Transmission Precautions Research Articles

Are we doing enough to control infection risk in Australian small animal veterinary practice? Findings from a mixed methods study.

Managing risk effectively within small animal veterinary practice is integral for staff, patient and client safety. Veterinary personnel are exposed to many risks, including bites, scratches, sharps injuries and exposure to zoonotic diseases and multi-resistant organisms. Patients may also be exposed to healthcare-associated infections, including multi-resistant organisms. While veterinary owners/managers have a duty of care under legislated Workplace Health and Safety requirements, all staff have a responsibility to contribute to assessing and minimizing risk. The application of standard and transmission precautions will help with risk minimization. This study aimed to determine how small animal veterinary staff understand and perceive infection prevention and control risk and to provide recommendations to assist with risk mitigation. A mixed methods design was used. A digital questionnaire was administered to small animal veterinary staff in Australia to identify knowledge, attitudes and practices of risk related behaviors. Follow up focus groups were conducted with small animal practitioners to explore factors supporting and preventing veterinary staff from implementing recommended practices identified in the questionnaire. Small animal veterinary staff acknowledged they participated in many high-risk activities, including recapping needles and eating and drinking in patient care areas. Injuries were common, with 77% of staff receiving a bite or scratch, and 22% receiving a sharps injury in the preceding six months. Less than one in five of these incidents was reported. Staff agreed effective infection prevention and control was the responsibility of all staff, but a designated staff member should take responsibility for managing it. The practice owner/manager was integral to supporting and promoting recommended strategies, contributing to a positive workplace culture and improving safety for staff and patients. Small animal veterinary staff have some understanding of how to identify, report, manage and mitigate risk but were limited by their knowledge of infection prevention and control principles.

A cross sectional study to assess knowledge and self-expressed practices regarding universal precautions among nursing students

Background: Each year, 2 million healthcare workers (HCWs) are exposed to HBV, 9 million to HCV and 1 lakh 70 thousand to HIV. To reduce disease transmission, blood and body fluid precautions were recommended in 1983 by the United States Centre for Disease Control (CDC). Objective was to assess the knowledge and Self-Expressed Practices (SEPs) regarding universal precautions among B.Sc. Nursing (BSN) students and the association between knowledge and SEPs. Methods: A descriptive approach and cross-sectional study design was used. A total of 200 students from BSN 1st year, 2nd year and 3rd years 60, 70 and 70, respectively, consented to participate in the study. Bio-data profile, a self-structured questionnaire to assess knowledge and a Likert scale to assess SEP. Results: Only 2.9% of students of BSN 2nd year fall in the adequate knowledge category, whereas 56.67 % (n=60) students of 1st year, 71.5% (n=70) students of 2nd year, and 68.6% (n=70) students of 3rd year belonged to moderate knowledge category. 86.67% of students in BSN 1st year, 78.57% of students 2nd year and 68.57% of students 3rd year fall in the adequate SEPs category. Only BSN 3rd year students showed a significant association between knowledge and SEPs sum total score (p=0.02). Conclusions: Maximum students had moderate knowledge, but SEPs were in an inadequate category. Students repeatedly receive training regarding universal precautions as they are the future of the health care system, and continuous surveillance of occupational hazards should be conducted to ensure safety and awareness among students and other Health Care Workers (HCWs).

A quantitative evaluation of aerosol generation during cardiopulmonary resuscitation.

It is unclear if cardiopulmonary resuscitation is an aerosol-generating procedure and whether this poses a risk of airborne disease transmission to healthcare workers and bystanders. Use of airborne transmission precautions during cardiopulmonary resuscitation may confer rescuer protection but risks patient harm due to delays in commencing treatment. To quantify the risk of respiratory aerosol generation during cardiopulmonary resuscitation in humans, we conducted an aerosol monitoring study during out-of-hospital cardiac arrests. Exhaled aerosol was recorded using an optical particle sizer spectrometer connected to the breathing system. Aerosol produced during resuscitation was compared with that produced by control participants under general anaesthesia ventilated with an equivalent respiratory pattern tocardiopulmonary resuscitation. A porcine cardiac arrest model was used to determine the independent contributions of ventilatory breaths, chest compressions and external cardiac defibrillation to aerosol generation. Time-series analysis of participants with cardiac arrest (n = 18) demonstrated a repeating waveform of respiratory aerosol that mapped to specific components of resuscitation. Very high peak aerosol concentrations were generated during ventilation of participants with cardiac arrest with median (IQR [range]) 17,926 (5546-59,209 [1523-242,648]) particles.l-1 , which were 24-fold greater than in control participants under general anaesthesia (744 (309-2106 [23-9099]) particles.l-1 , p < 0.001, n = 16). A substantial rise in aerosol also occurred with cardiac defibrillation and chest compressions. In a complimentary porcine model of cardiac arrest, aerosol recordings showed a strikingly similar profile to the human data. Time-averaged aerosol concentrations during ventilation were approximately 270-fold higher than before cardiac arrest (19,410 (2307-41,017 [104-136,025]) vs. 72 (41-136 [23-268]) particles.l-1 , p = 0.008). The porcine model also confirmed that both defibrillation and chest compressions generate high concentrations of aerosol independent of, but synergistic with, ventilation. In conclusion, multiple components of cardiopulmonary resuscitation generate high concentrations of respiratory aerosol. We recommend that airborne transmission precautions are warranted in the setting of high-risk pathogens, until the airway is secured with an airway device and breathing system with a filter.

Impact of the coronavirus disease-2019 pandemic on Veterans Health Administration Sleep Services.

To understand the impact of the coronavirus disease-2019 pandemic on sleep services within the United States Department of Veterans Affairs using separate surveys from "pre-COVID" and pandemic periods. Data from a pre-pandemic survey (September to November 2019) were combined with data from a pandemic-period survey (August to November 2020) to Veterans Affairs sleep medicine providers about their local sleep services within 140 Veterans Affairs facilities). A total of 67 (47.9%) facilities responded to the pandemic online survey. In-lab diagnostic and titration sleep studies were stopped at 91.1% of facilities during the pandemic; 76.5% of facilities resumed diagnostic studies and 60.8% resumed titration studies by the time of the second survey. Half of the facilities suspended home sleep testing; all facilities resumed these services. In-person positive airway pressure clinics were stopped at 76.3% of facilities; 46.7% resumed these clinics. Video telehealth was either available or in development at 86.6% of facilities and was considered a lasting addition to sleep services. Coronavirus disease-2019 transmission precautions occurred at high rates. Sleep personnel experienced high levels of stress, anxiety, fear, and burnout because of the pandemic and in response to unexpected changes in sleep medicine care delivery. Sleep medicine services within the Veterans Affairs evolved during the pandemic with many key services being interrupted, including in-lab studies and in-person positive airway pressure clinics. Expansion and initiation of telehealth sleep services occurred commonly. The pandemic adversely affected sleep medicine personnel as they sought to maintain access to care.

Optimal control analysis for a Candida auris nosocomial infection model with environmental transmission

In this paper, we propose a mathematical model to investigate the role of environmental reservoirs in the transmission dynamics of the rising Candida auris infections in nosocomial settings. The ability of the pathogen to resist commonly used hospital disinfectants ensures its persistent contamination of hospital surfaces and medical equipment readily leading to patient colonization. Colonized patients shed the pathogen into their surroundings thereby increasing the fungal concentration in the hospital environment. We analyze the model for its basic mathematical properties, perform sensitivity analysis, and formulate an optimal problem to determine the efficiency of control interventions, namely, standard transmission precautions, proper laboratory identification, and isolation of patients identified with colonization in reducing the contamination and transmission of C. auris infections. We characterize the optimal controls using Pontryagin's Minimum Principle and further prove the uniqueness of the optimality system. Numerical simulations are performed to substantiate the theoretical analysis, and the results are illustrated graphically.

Knowledge about Hepatitis B Virus and Relevant Safety Precautions among Dental Students in Kurdistan Region, Iraq.

Background Hepatitis B virus (HBV) is still a major health problem worldwide, placing healthcare workers, medical and dental students, and professionals at higher occupational risk. The present study aimed to evaluate the level of knowledge about this virus and relevant safety precautions among dental students in the Kurdistan region of Iraq. Materials and methods. This cross-sectional study was conducted among the third, fourth, and fifth stage dental students of Hawler Medical, Sulaimani, and Duhok universities. Data on the students' demographic characteristics and their knowledge about HBV (16 close-ended questions) and safety precaution measures (10 close-ended questions) were collected by means of a questionnaire. Analysis of variance was used to compare the mean of knowledge and safety precaution scores. Results In total, 372 students (mean age 21.77 ± 1.31 years) completed the questionnaires. The mean scores for knowledge and safety precautions were 13.17 ± 2.09 and 8.05 ± 1.61, respectively. Respondents from Hawler Medical University showed statistically significantly higher knowledge levels than their counterparts in Sulaimani and Duhok universities (p = 0.012). Conclusions The majority of surveyed dental students are aware of HBV, its mode of transmission, infection, complications, vaccination, and safety precautions required to prevent the spreading of the virus. While the levels of knowledge about HBV and safety precautions among the dental students in the Kurdistan region of Iraq were generally acceptable, differences in knowledge level were identified between the universities, and these may be related to their educational and training programs.

Pregnancy and COVID-19: prevention, vaccination, therapy, and beyond

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has alarmed the world since its first emergence. As pregnancy is characterized by significant changes in cardiovascular, respiratory, endocrine, and immunological systems, there are concerns on issues like the course of disease in pregnant women, safety of medications, route of delivery and risk of obstetric complications. The aim of this review is to summarize the current literature in the management of pregnant women during the COVID-19 pandemic. Although more than 90% of pregnant women with COVID-19 recover without serious morbidity, rapid deterioration of disease and higher rates of obstetric complications may be observed. The risk of vertical transmission has not been clearly revealed yet. Decreasing the number of prenatal visits, shortening the time allocated for the examinations, active use of telemedicine services, limiting the number of persons in healthcare settings, combining prenatal tests in the same visit, restricting visitors during the visits, providing a safe environment in healthcare facilities, strict hygiene control, and providing personal protective equipment during the visits are the main strategies to control the spread of disease according to current guidelines. Although new medication alternatives are being proposed every day for the treatment of COVID-19, our knowledge about the use of most of these drugs in pregnancy is limited. Preliminary results are promising for the administration of SARS-CoV-2 vaccines in the pregnant population. Timing of delivery should be decided based on maternal health condition, accompanying obstetric complications and gestational age. Cesarean delivery should be performed for obstetric indications. Breast feeding should be encouraged as long as necessary precautions for viral transmission are taken. In conclusion, an individualized approach should be provided by a multidisciplinary team for the management of pregnant women with COVID-19 to achieve favorable outcomes.

COVID-19 Infection, Prevention, and Control Considerations in the Obstetric Environment.

Pregnancy increases the risk of severe illness due to coronavirus disease 2019 (COVID-19). Thus, prevention of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in all obstetrical health care settings requires consistent implementation of multiple evidence-based practices and consideration of local epidemiology, local regulations for COVID-19, and guidance from the Centers for Disease Control and Prevention and Professional Societies. COVID-safe practices should be implemented for patients, visitors/support persons, and health care personnel and include screening, appropriate personal protective equipment, and transmission precautions. Vaccination of all health care personnel, pregnant people, and their support persons remains the best strategy to prevent COVID-19.

#95: Clinical Profile and Outcome of Pediatric Acute Lymphoblastic Leukemia Patients with Tuberculosis at the Philippine General Hospital

Abstract Background The Philippines remains one of the countries on the WHO list of high-burden countries for tuberculosis (TB), and malignancy has long been recognized as a risk factor for this disease. This report describes the clinical profile and outcomes of pediatric patients with acute lymphoblastic leukemia (ALL) diagnosed with tuberculosis. Methods Medical records of pediatric patients with ALL consulting at the University of the Philippines – Philippines General Hospital diagnosed from January 2015 to December 2017 (excluding those with concomitant HIV infection) were reviewed. Those diagnosed with tuberculosis infection were further analyzed, obtaining demographic data, results of diagnostics, and treatment. Results Out of 102 patients, 5 were found to have tuberculosis, all of them being male, with an average age of 7.2 years old. All cases were pulmonary, with one patient having multi-drug-resistant TB. PPD was positive in 4 cases, with indurations measuring &amp;gt;10mm, while chest radiographs showed nonspecific findings for 3 patients. Of 3 patients who underwent sputum AFB testing, one had a positive result. While 1 patient was diagnosed with TB and ALL concurrently, majority of patients were diagnosed after entering remission. Three patients completed 6 months of TB treatment, while 1 patient is still on medication for multi-drug-resistant tuberculosis. One patient abandoned treatment. Conclusion In this group of ALL patients, malnutrition and corticosteroid use were not found to be independent risk factors for TB. As TB disease may be due to reactivation of latent TB infection (LTBI) during immunosuppression, screening for LTBI may be a worthwhile strategy to decrease morbidity. Transmission precautions are emphasized to reduce acquired TB infection in immunocompromised populations.

Less attention paid to waterborne SARS-CoV-2 spreading in Beijing urban communities.

SARS-CoV-2 has been detected in various environmental media. Community and individual-engaged precautions are recommended to stop or slow environmentally-mediated transmission. To better understand the individual’s awareness of and precaution to environmental dissemination of SARS-CoV-2, an online survey was conducted in Beijing during March 14–25, 2020. It is found that the waterborne (especially wastewater mediated) spreading routes are far less perceived by urban communities. The precautions for wastewater transmission are less favored by the public than airborne and solid waste mediated spreading routes. Such risk communication asymmetry in waterborne transmission will be further enlarged in places with fragile water system. Furthermore, education level is the most significant attribution (Sig. < 0.05) that causes the difference of awareness and precautions of the waterborne transmission among the respondents, according to the variance analysis results. Our survey results emphasize the urgent need for evidence-based, multifactorial precautions for current and future outbreaks of COVID-19.Electronic Supplementary MaterialSupplementary material is available in the online version of this article at 10.1007/s11783-021-1398-2 and is accessible for authorized users.

COVID-19 infection rate among tertiary referral center otorhinolaryngology healthcare workers.

ImportanceOtorhinolaryngology is considered one of the medical specialties with a high risk for exposure to corona disease 2019 (COVID-19). Uncontrolled transmission in a hospital department poses a risk to both healthcare workers (HCWs) and patients.ObjectiveTo monitor SARS-CoV-2 incidence, transmission, and antibody development among HCWs to identify high risk procedures, pathways, and work areas within the department.MethodsProspective cohort study of HCWs using repetitive oro- and nasopharygeal swab samples, antibody tests, and self-reported symptoms questionnaires at a tertiary referral center in Copenhagen, Denmark.Results347/361 (96%) HCWs participated. Seven (1.9%) were positive on swab tests and none had symptoms. Fifteen (4.2%) developed antibodies. Only one case of potential transmission between HCWs was identified. Infection rates were low and no procedures or areas within the department were identified as exposing HCWs to a higher risk.Conclusions and relevanceAdherence to the surveillance program was high. The low incidence among HCW during the first wave of the COVID-19 pandemic may reflect local transmission and infection control precautions, as well as a low infectious burden in the Danish society.

Discontinuation of Transmission Precautions for COVID-19 Patients: Polymerase Chain Reaction Diagnostics, Patient Delays, and Cycle Threshold Values.

BackgroundThe decision of when it is safe to discontinue transmission-based precautions for SARS-CoV-2 coronavirus disease 2019 (COVID-19) hospitalized patients has been controversial. The Centers for Disease Control and Prevention offered reverse transcriptase polymerase chain reaction (PCR) diagnostic test- or symptom-based guidelines.MethodsA retrospective chart review of Vidant Health system, Eastern North Carolina, was conducted. Length of stay, days in isolation unit, and date appropriate for discharge or isolation discontinuation based on the symptom-based strategy were recorded.ResultsOf 196 COVID hospitalized patients, 34 had repeated COVID PCR tests 3 or more days from their first positive test result. Half of these patients experienced delays in release from transmission-based precautions because of repeated positive PCR test results and use of the test-based approach. This resulted in an additional 166 days of hospitalization, costing an estimated $415,000. Furthermore, 2 subjects had a combined 16-day delay in necessary medical procedures. Most of the COVID PCR platforms yield quantitative results in the form of cycle threshold (Ct) values, the number of cycles needed to detect the genome. These values have also been used to assess whether patients are likely to remain contagious. None of our patients who met the criteria for symptom-based strategy for transmission-based precaution discontinuation had positive PCR test results with Ct values lower than 25, but 4 had Ct values lower than 30.ConclusionsConcerns surround immunocompromised patients and those treated with steroids who might be delayed or incapable of stopping viral replication and thus remain contagious. Our results suggest that clinicians use all available data including Ct values to evaluate the safety of discontinuation of transmission precautions.

A Narrative Review of Personal Protective Equipment Uses in Coronavirus Disease 2019 and Its Disposable Practices.

Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for causing coronavirus disease 2019 (COVID-19), is transmitted through close contact and droplets, people, especially those at risk of infection, must follow preventive measures in the community and healthcare settings. Healthcare personnel (HCP) must appropriately select and use personal protective equipment (PPE) with sensible donning and doffing and disposal practices. A narrative review of the existing literature was conducted, in which articles from Scopus, PubMed, Google Scholar, ScienceDirect, and Web of Science were collected. The primary findings of the retained articles were reviewed according to official recommendations on PPE use. The World Health Organization (WHO), US Centers for Disease Control and Prevention (CDC), and European Center for Disease Control and Prevention (ECDC) recommend standard precautions for contact transmission, respiratory transmission, and droplet precautions among HCPs caring for patients with COVID-19. Indeed, healthcare workers working in high-risk areas, as well as the public, when social distancing cannot be assured, must wear PPE such as face mask and protective eyewear to prevent the transmission of SARS-CoV-2 infection. Due to the increased use of PPE, the potentially infectious waste stream has been rapidly increasing, requiring safe and adequate solid waste management. The proper use of PPE and management of waste generated from COVID-19 care centers can reduce the risk of COVID-19 infection. These measures should be implemented to counter the rapid spread and any long-term impacts of the current pandemic.

Optimizing Peripandemic Care for Veteran Major Non-Traumatic Lower Extremity Amputees: A Proposal Informed by a National Retrospective Descriptive Analysis of COVID-19 Risk Factor Prevalence.

IntroductionIn response to the Coronavirus 2019 (COVID-19) pandemic, vascular surgeons in the Veteran Affairs Health Care System have been undertaking only essential cases, such as advanced critical limb ischemia. Surgical risk assessment in these patients is often complex, considers all factors known to impact short- and long-term outcomes, and the additional risk that COVID-19 infection could convey in this patient population is unknown. The European Centre for Disease Prevention and Control (ECDC) published risk factors (ECDC-RF) implicated in increased COVID-19 hospitalization and case-fatality which have been further evidenced by initial reports from the United States Centers for Disease Control and Prevention. CDC reports additionally indicate that African American (AA) patients have incurred disparate infection outcomes in the United States. We set forth to survey the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database over a nearly 20 year span to inform ongoing risk assessment with an estimation of the prevalence of ECDC-RF in our veteran critical limb ischemia population and investigate whether an increased COVID-19 comorbidity burden exists for AA veterans presenting for major non-traumatic amputation.Materials and MethodsThe VASQIP database was queried for all above knee amputation (AKA) and below knee amputation (BKA) completed 1999–2018 after IRB approval (MIRB:#02507). Patient race and ECDC-RF including male gender, age > 60 years, smoking status, hypertension, diabetes, chronic obstructive pulmonary disease, cancer, and cardiovascular disease were recorded from preoperative patient history. AKA and BKA cohorts were compared via χ2-test with Yates correction or unpaired t-test and a subgroup analysis was conducted between AA and all other race patients for COVID-19 comorbidities in each cohort.ResultsVASQIP query returned 50,083 total entries. Average age was 65.1 ± 10.4 years and 68.2 ± 10.5 years for BKA and AKA cohorts, respectively, (P < .0001) and nearly all patients were male (99%). At least one ECDC-RF comorbidity was present in 25,526 (88.7%) of BKA and 17,558 (82.4%) of AKA patients (P < .0001). AA BKA patients were significantly more likely than non-AA BKA patients to present with at least one ECDC-RF comorbidity (P = .01).ConclusionsAccording to a large national Veterans Affairs database, there are high rates of ECDC-RF in veteran amputees. During the present crisis, management of these patients should incorporate telehealth, expedient discharge, and ongoing COVID-19 transmission precautions.

Reducing Aerosol-Related Risk of Transmission in the Era of COVID-19: An Interim Guidance Endorsed by the International Society of Aerosols in Medicine.

National and international guidelines recommend droplet/airborne transmission and contact precautions for those caring for coronavirus disease 2019 (COVID-19) patients in ambulatory and acute care settings. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, an acute respiratory infectious agent, is primarily transmitted between people through respiratory droplets and contact routes. A recognized key to transmission of COVID-19, and droplet infections generally, is the dispersion of bioaerosols from the patient. Increased risk of transmission has been associated with aerosol generating procedures that include endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation before intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, noninvasive positive-pressure ventilation, tracheostomy, and cardiopulmonary resuscitation. The knowledge that COVID-19 subjects can be asymptomatic and still shed virus, producing infectious droplets during breathing, suggests that health care workers (HCWs) should assume every patient is potentially infectious during this pandemic. Taking actions to reduce risk of transmission to HCWs is, therefore, a vital consideration for safe delivery of all medical aerosols. Guidelines for use of personal protective equipment (glove, gowns, masks, shield, and/or powered air purifying respiratory) during high-risk procedures are essential and should be considered for use with lower risk procedures such as administration of uncontaminated medical aerosols. Bioaerosols generated by infected patients are a major source of transmission for SARS CoV-2, and other infectious agents. In contrast, therapeutic aerosols do not add to the risk of disease transmission unless contaminated by patients or HCWs.

PIN70 Knowledge Towards Universal Safety Precautions Among Healthcare Population in India during Initial Phase of COVID-19: A Web Based Survey

The first case of COVID–19 in India surfaced in the state of Kerala on January 31 2020. Hence, an early exploration of knowledge and perceptions of medical students and professionals, regarding transmission and universal safety precautions during the early phase of the disease is aimed in the study. A web-based, online cross-sectional survey was conducted among the healthcare population in India during late February 2020. A questionnaire was designed to assess the knowledge regarding clinical and epidemiological characters of COVID-19 along with the universal safety precautions. A virtual snowball sampling using predesigned google forms were disseminated through social media networks. Descriptive statistics along with Chi-square test were performed with a p-value of < 0.05 was considered as statistically significant. Among the 983 participants who provided their consent of willingness and completed the questionnaire, 63% represented pharmacy profession followed by 14% from nursing discipline. Even though the age of study population varied from 18 – 79 years and with a female preponderance of 54.1% (n = 532), students as a whole participated largely in the study (68.1%, n = 670). A mean knowledge score of 3.21±1.14 (out of 6) indicated inadequate knowledge among the study population. The study revealed that there is no statistically significant difference in knowledge score based on age, place of living and medical discipline, but a significant association was observed between knowledge level and gender (p = 0.004). The knowledge regarding universal safety precautions and transmission of a disease is vital in preventing the community spread, while an inadequate and improper knowledge among medical population can amplify the spread. Online classes and training programs should be initiated at the university levels as well as a part of CME curriculum for up gradation of early knowledge regarding COVID-19.

Exploring the illness experiences amongst families living with 2019 coronavirus disease in Ghana: Three case reports.

The 2019 corona virus disease (COVID-19) has wreaked havoc on countries, communities and households. Its effect on individuals and their families, although enormous, has not been adequately explored. We thus present a report on the illness experiences of three families in Ghana who had at least one member diagnosed with COVID-19. We interviewed them and recorded their commonest fears, such as death, stigmatisation and collapse of family business. Respondents had a fair idea about symptoms of COVID-19, mode of transmission and safety precautions. Family separation and loss of income were some of the adverse effects expressed. Majority of them were hopeful that family members with COVID-19 would recover and be reunited. The biopsychosocial impact of COVID-19 is tremendous and family physicians and other primary care workers have an essential role to play in addressing this.

Knowledge of dental academics about the COVID-19 pandemic: a multi-country online survey

BackgroundCOVID-19 is a global pandemic affecting all aspects of life in all countries. We assessed COVID-19 knowledge and associated factors among dental academics in 26 countries.MethodsWe invited dental academics to participate in a cross-sectional, multi-country, online survey from March to April 2020. The survey collected data on knowledge of COVID-19 regarding the mode of transmission, symptoms, diagnosis, treatment, protection, and dental treatment precautions as well as participants’ background variables. Multilevel linear models were used to assess the association between dental academics’ knowledge of COVID-19 and individual level (personal and professional) and country-level (number of COVID-19 cases/ million population) factors accounting for random variation among countries.ResultsTwo thousand forty-five academics participated in the survey (response rate 14.3%, with 54.7% female and 67% younger than 46 years of age). The mean (SD) knowledge percent score was 73.2 (11.2) %, and the score of knowledge of symptoms was significantly lower than the score of knowledge of diagnostic methods (53.1 and 85.4%, P < 0.0001). Knowledge score was significantly higher among those living with a partner/spouse than among those living alone (regression coefficient (B) = 0.48); higher among those with PhD degrees than among those with Bachelor of Dental Science degrees (B = 0.48); higher among those seeing 21 to 30 patients daily than among those seeing no patients (B = 0.65); and higher among those from countries with a higher number of COVID-19 cases/million population (B = 0.0007).ConclusionsDental academics had poorer knowledge of COVID-19 symptoms than of COVID-19 diagnostic methods. Living arrangements, academic degrees, patient load, and magnitude of the epidemic in the country were associated with COVD-19 knowledge among dental academics. Training of dental academics on COVID-19 can be designed using these findings to recruit those with the greatest need.

A Case report about clinical outcome of a 37-week pregnant woman with COVID-19 in Bangladesh

Background: A highly pathogenic coronavirus named SARS‐CoV‐2 emerged in December 2019 in Wuhan, China after Severe Acute Respiratory Syndrome coronavirus (SARS‐CoV) and Middle East Respiratory Syndrome coronavirus (MERS‐CoV). It spreads rapidly around the world. Pregnant women are at risk for COVID-19 which is more likely to have complications and even progress to severe illness. There is not enough data to determine the effect of COVID-19 infection on the fetus.Case report: We report a case of 37-week pregnant woman with COVID-19 infection in Bangladesh who delivered an infant with no evidence of COVID-19 by RT-PCR. Careful transmission precautions with the infant, including contact, droplet, and airborne precautions helps us to deliver a negative baby.Conclusion: This case provides an initial view of the outcome associated with pregnancy-related COVID-19 and several effective strategies for managing pregnant women with COVID-19. Although SARS-CoV-2 may increase health risks to both mothers and infants during pregnancy, intensive attention should be paid to pregnant patients.

A primer for pediatric radiologists on infection control in an era of COVID-19.

Pediatric radiology departments across the globe face unique challenges in the midst of the current COVID-19 pandemic that have not been addressed in professional guidelines. Providing a safe environment for personnel while continuing to deliver optimal care to patients is feasible when abiding by fundamental recommendations. In this article, we review current infection control practices across the multiple pediatric institutions represented on the Society for Pediatric Radiology (SPR) Quality and Safety committee. We discuss the routes of infectious transmission and appropriate transmission-based precautions, in addition to exploring strategies to optimize personal protective equipment (PPE) supplies. This work serves as a summary of current evidence-based recommendations for infection control, and current best practices specific to pediatric radiologists.Electronic supplementary materialThe online version of this article (10.1007/s00247-020-04713-1) contains supplementary material, which is available to authorized users.
