Use Of Personal Protective Measures Research Articles

Practices of Personal Protective Measures against SARS-Cov-2 among Undergraduate Medical Students in South India

Introduction: The use of personal protective measures holds relevance despite mass immunization coverage of COVID-19 vaccination in the population. This is because vaccination only gives protection from severe COVID-19 and does not prevent the risk of infection. Medical students can be vital in training people in infection control practices. The study aimed to assess the practices of undergraduate medical students regarding personal protective measures against COVID-19. Methods: A cross-sectional study was done among first to final-year students at a private medical college in Mangalore. Data were collected using a Microsoft form. Results: The mean age of the 302 participants was 21.2±1.6 years. The majority of them were females [179 (59.3%)]. Face mask was worn by 295(97.7%) participants. Non-recommended types of face masks like using cloth masks [108 (36.6%)] and handkerchiefs [7 (2.4%)] were reported by participants. 35 (11.9%) of them wore the face mask incorrectly. Periodicity of replacement of disposable type masks was not done every day by 181(61.4%) participants. 142(48.1%) of them did not dispose of masks whenever they became moist on every occasion. Only 79 (26.8%) always practiced proper disposal of face masks. Hand sanitizer to disinfect hands was always used by 102 (33.8%) participants. Only 42 (13.9%) participants practiced correct practice of hygiene hand wash always. Only 58 (19.2%) participants had a good level of practice. Practice level was significantly poorer among males and first-year students. Conclusion: Several gaps in preventive practices against COVID-19 were identified, particularly among males and first-year students. These issues need to be addressed among medical students in future training programs.

Mathematical modelling of COVID-19 transmission with optimal control and cost-effectiveness analysis

The present global health threat is the novel coronavirus disease (COVID-19), caused by a new strain of the SARS-CoV-2 coronavirus. In this study, have employed optimal control theory, aided by Pontryagin’s Maximum Principle, to explore optimal control measures. Specifically, we have investigated time-dependent intervention strategies, including the proper use of personal protective measures and vaccination. Bifurcation analysis was conducted and results shows that the model system exhibit a forward bifurcation. The optimal control system have been numerically simulated using the fourth-order Runge–Kutta methods. The results show that the implementation of the combination of the two interventions was more significant and effective in minimizing the spread of the COVID-19 than the implementation of a single control measure. These findings underscore the significance of multifaceted intervention approaches over singular control measures. Notably, the combined implementation of interventions emerges as markedly more effective in containing COVID-19 transmission. Moreover, our study identifies personal protective measures as a particularly cost-effective intervention, offering substantial relief from the burden of the pandemic within the population. We anticipate that our research will inform evidence-based approaches to pandemic control and aid in the ongoing global efforts to safeguard public health.

Association of known SARS-CoV-2 serostatus and adherence to personal protection measures and the impact of personal protective measures on seropositivity in a population-based cross-sectional study (MuSPAD) in Germany

BackgroundIn 2020/2021 in Germany, several non-pharmacological interventions were introduced to lower the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We investigated to what extent knowledge of prior infection with SARS-CoV-2 or vaccination status influenced the use of personal protection measures (PPM). Further, we were interested in the effect of compliance with PPM on SARS-CoV-2 serostatus.MethodsData was based on a sequential, multilocal seroprevalence study (MuSPAD), carried out in eight locations from July 2020 to August 2021. We estimated the association between a known SARS-CoV-2 serostatus (reported positive PCR test or vaccination) and self-reported PPM behavior (hand hygiene, physical distancing, wearing face mask), just as the association of PPM compliance with seropositivity against nucleocapsid (NC), receptor-binding domain (RBD), and spike protein (S) antigens. We identified relevant variables and deduced adjustment sets with directed acyclic graphs (DAG), and applied mixed logistic regression.ResultsOut of the 22,297 participants (median age: 54 years, 43% male), 781 were classified as SARS-CoV-2-infected and 3,877 had a vaccinated immune response. Vaccinated individuals were less likely to keep 1.5 m distance [OR = 0.74 (95% CI: 0.57–0.97)] and only partly physically distanced [OR = 0.71 (95% CI: 0.58–0.87)]. Participants with self-reported positive PCR test had a lower chance of adhering partly to physical distancing [OR = 0.70 (95% CI: 0.50–0.99)] in comparison to the reference group. Higher odds of additionally wearing a face mask was observed in vaccinated [OR = 1.28 (95% CI: 1.08–1.51)] even if it was not obligatory. Overall, among unvaccinated participants, we found little evidence of lower odds of seropositivity given mask wearing [OR: 0.91 (95% CI: 0.71–1.16)], physical distancing [OR: 0.84 (95% CI: 0.59–1.20)] and no evidence for completely adhering to hand cleaning [OR: 0.97 (95% CI: 0.29–3.22)].ConclusionsA known confirmed prior infection and vaccination may have the potential to influence adherence to PPM.

Self care and wellbeing in the face of COVID-19: Multidisciplinary perspectives and interprofessional experiences.

The human toll which has resulted from the coronavirus disease 2019 pandemic is clearly recognised. No single event in recent times has had such profound effects on health services and their staff wellbeing around the world. Policy making has been led by the requirement for confinement and surveillance to limit spread of the disease, and in clinical settings the impact of the necessity for the use of personal protective measures has caused huge strains on practice clinically and professionally. In this paper we share experiences from the pandemic, explore the social and organisational factors at stake and make some suggestions for both personal wellbeing practice and a systems response to the ongoing staff wellbeing challenges of the pandemic.

Knowledge on prevention and management of snake bite among adults in rural area of West Bengal

Background: Snake bite and its consequences may be largely prevented with adequate knowledge. Better knowledge can lead to positive attitude and subsequently good practices. Hence, it is of utmost need that people should have adequate knowledge regarding snake bite and its management. Aims and Objectives: The aims of this study were to assess the knowledge regarding prevention and management of snake bite among adults in a rural area of West Bengal and to find out any association between sociodemographic profile and knowledge on prevention as well as management of snake bite among the study participants. Materials and Methods: A community-based and observational descriptive study was conducted in the rural field practice area of Medial College, Kolkata, West Bengal for of 2 months. The study participants who were willing to participate in the study and gave written informed consent were included in the study. A pre-designed, pre-tested, and semi-structured data collection form was used. It was developed based on similar type of previous studies and was modified according to the local culture. The data collection form comprised sociodemographic profile of the study participants, their knowledge regarding snake bite, and its prevention and availability of first aid management. Results: A total of 134 participants were included in the study. The mean age was 45.81 ± 8.00 years. It was observed that majority of the study subjects believed in the knowledge that all types of snakes are poisonous (93.2%) and leads to death (90.3%). First aid measures such as application of tourniquet that was seen in only 4.4% of the cases. However, more than half of the study subjects (71.6%) believed in sucking the venom out of the wound. It was noted that higher education status, improved social class had better knowledge score of snake bite prevention and management as compared to their counterparts and this association was found to be statistically significant (P < 0.001). Conclusion: Knowledge of the study subjects on snake bite and its prevention is good, but still a large number of participants have inadequate knowledge on snake bite and its prevention. Community-based awareness program on prevention and management of snake bite, use of personal protective measures, and training of peripheral health workers ware specifically recommended.

Perceived Effectiveness and Sustainability of Face Masks Among German Citizens During the 2nd Wave of the COVID-19 Pandemic—A Cross-Sectional Study

BackgroundThe COVID-19 pandemic, which began at the end of 2019, has led to a significant increase in the demand for face masks in Germany and around the globe. Since non-reusable masks are often not correctly disposed of and are not biodegradable, their increasing use harms the environment. Both the ongoing pandemic and the rising environmental pollution eventually pose a threat to human health. Yet, it is unclear whether mask users are conscious of this, and which factors influence their choice of face masks. This study investigates the user preferences, perceived effectiveness, and the sustainability of different mouth/nose protection (MNP) to lay the foundation for developing more sustainable and effective alternatives.MethodsA national (Germany-wide) cross-sectional study with a sample of 1,036 participants was conducted. Descriptive data analysis was deployed to describe trends and socio-demographic differences among the respondents. Different socio-demographic groups among the respondents were compared regarding their infection risk perception, compliance toward the use of personal protective measures, their choice of MNP, and knowledge level of sustainability and effectiveness of various MNP using inferential statistics (Chi2 test/Whitney–Mann-U-test/Kruskal–Wallis-test).ResultsThe results suggest that, in addition to protective effectiveness, the reusability of MNP is important to not just most respondents but especially to older participants. In contrast, the price, shape, and design were not as important. The knowledge level of the effectiveness and sustainability of MNP was high among the participants and was not associated with socioeconomic characteristics. However, the knowledge level directly influenced the choice of MNP.ConclusionThere seems to be an inclination to use sustainable MNP, provided their level of protection is similar to medical masks or FFP2/FFP3 masks. The willingness to wear a sustainable option increases with age.

Resurgence of Interest in Eastern Equine Encephalitis Virus Vaccine Development.

Eastern equine encephalitis virus (EEEV; Family Togaviridae), is an endemic pathogen first isolated in 1933 with distribution primarily in the eastern US and Canada. The virus has caused periodic outbreaks in both humans and equines along the eastern seaboard and through the southern coastal states. While the outbreaks caused by EEEV have been sporadic and varied geographically since the discovery of the virus, it has continued to expand its range moving into the Midwest states as well. Additionally, one of the largest outbreaks was recorded in 2019 prompting concerns that outbreaks were becoming larger and more frequent. Because the virus can cause serious disease and because it is transmissible by both mosquitoes and aerosol, there has been renewed interest in identifying potential options for vaccines. Currently, there are no licensed vaccines and control relies completely on the use of personal protective measures and integrated vector control which have limited effectiveness for the EEEV vectors. Several vaccine candidates are currently being developed; this review will describe the multiple options under consideration for future development and assess their relative advantages and disadvantages.

Immunogenicity and Safety of the BNT162b2 mRNA COVID-19 Vaccine Among Actively Treated Cancer Patients.

BackgroundActivity and safety of the SARS-CoV-2 BNT162b2 vaccine in actively treated patients with solid tumors is currently unknown.MethodsWe conducted a retrospective study of 326 patients with solid tumors treated with anticancer medications to determine the proportion of cancer patients with immunogenicity against SARS-CoV-2 following 2 doses of the BNT162b2 vaccine. The control group comprised 164 vaccinated healthy adults. Anti-SARS-CoV-2 S immunoglobulin G antibodies were measured using a level greater than 50 AU/mL as a cutoff for seropositivity. Information on adverse effects was collected using a questionnaire. All statistical tests were 2-sided.ResultsMost patients (205, 62.9%) were treated with chemotherapy either alone or with additional therapy; 55 (16.9%) were treated with immune checkpoint inhibitors and 38 (11.7%) with targeted therapy alone; 28 (8.6%) received other combinations. The vaccine was well tolerated, and no severe side effects were reported. Among patients with cancer, 39 (11.9%) were seronegative compared with 5 (3.0%) of the control group (P = .001). Median immunoglobulin G titers were statistically significantly lower among patients with cancer compared with control (931 AU/mL vs 2817 AU/mL, P = .003). Seronegativity proportions were higher in the chemotherapy-treated group (n = 19; 18.8%) compared with the immune checkpoint inhibitor–treated patients (n = 5; 9.1%) and with those treated with targeted therapy (n = 1; 2.6%) (P = .02). Titers were also statistically significantly different among treatment types (P = .002).ConclusionsThe BNT162b2 vaccine is safe and effective in actively treated patients with cancer. The relatively lower antibody titers and lower proportion of seropositive patients, especially among chemotherapy-treated patients, call for continuing the use of personal protective measures in these patients, even following vaccination.

Preventing Vector-Borne Transmission of Zika Virus Infection During Pregnancy, Puerto Rico, USA, 2016-20171.

We examined pregnant women’s use of personal protective measures to prevent mosquito bites during the 2016–2017 Zika outbreak in Puerto Rico. Healthcare provider counseling on recommended measures was associated with increased use of insect repellent among pregnant women but not with wearing protective clothing.

Pre and post training study of awareness about biomedical waste management among health care personnel in medical college hospital in Western Rajasthan

The biomedical waste is any waste that is generated during diagnosis, treatment or immunization of human beings or animals, or in the research activities of biological. The amount of biomedical waste being generated is increasing day by day which can pollute the environment and can spread many harmful diseases if not handled properly. Health care workers in our country are still not fully aware about proper disposal of BMW. The objective of the study was to access the effect of training on health care personnel about the biomedical waste management in our institution. : A pre designed questionnaire was used for data collection before and after hands on training. Total 250 health care personnel including doctors, nurses, lab technicians and class IV employees working in our institution participated in study. Data was analysed using SPSS software and results were interpreted into percentages. Doctors, nurses and lab technicians had good knowledge regarding biomedical waste management before but the knowledge of class IV employees (cleaners and maintenance personnel) was not good but all group showed good improvement in their Knowledge regarding biomedical waste management after training. There should be periodic trainings and workshops with special focus on proper use of personal protective measures for all health personnel having special focus on paramedical and cleaner staff about Biomedical waste management rules.

Awareness and use of Personal Protective Measures against Mosquito Borne Diseases

Background: The key success of Vector Borne Diseases control depends not only on services provided by health authorities but also on awareness of vector borne diseases and community participation. Objectives: The present study was conducted to assess the knowledge and use of PPMs against MBDs in field practice area of UHTC amongst study participants. Methods: It was a community based Cross-sectional study conducted in the field practice area of UHTC among 245 families. Result: 94.7% respondents were aware that malaria is transmitted by mosquito bite. Maximum 102 families were using citronella stick, followed by 98 families using liquid vaporizer. 7.79% participants were using PPM adequately while 3.21 % were using PPM correctly. Conclusion: The general awareness regarding important parameters of mosquito borne diseases was less amongst respondents. Less cost, easy availability and simplicity in using PPM were the reasons cited by the respondents regarding their preferences for choosing PPM.

Covid-19 pandemic and the skin.

In the beginning of the COVID‐19 outbreak, skin manifestations, if present, were not paid enough attention. Then, the focus moved toward the impact of the prolonged use of personal protective measures in both healthcare workers and patients. In the meantime, attention is increasingly paid to dermatology as a result of the concern for certain groups of dermatologic patients, including those whose condition may worsen by the thorough disinfection measures and those treated with immunosuppressants or immunomodulators. Following patients with psoriasis on biological therapy, as well as other inflammatory and autoimmune cutaneous disorders such as atopic dermatitis, pemphigus, pemphigoid diseases, and skin cancer provoked the interest of dermatologists. Finally, an intriguing question to the dermatologic society was whether skin changes during COVID‐19 infection exist and what could be their diagnostic or prognostic value. Here, we summarize skin conditions during the COVID‐19 pandemic, patient information, and expert recommendations and give an overview about the registries launched to document skin changes during COVID‐19, as well as details about certain patient groups infected with SARS‐CoV‐2, for example, psoriasis, atopic dermatitis, and autoimmune bullous diseases.

Context matters: Contrasting behavioral and residential risk factors for Lyme disease between high-incidence states in the Northeastern and Midwestern United States

The dynamics of zoonotic vector-borne diseases are determined by a complex set of parameters including human behavior that may vary with socio-ecological contexts. Lyme disease is the most common vector-borne disease in the United States. The Northeast and upper Midwest are the regions most affected - two areas with differing levels of urbanization and differing sociocultural settings. The probability of being infected with Lyme disease is related to the risk of encounters with Ixodes scapularis ticks infected with Borrelia burgdorferi sensu lato, which reflects both the environmental tick hazard and human behaviors. Herein, we compare behavioral and peridomestic risk factors perceived to influence the risk for human-tick encounters between two high-incidence states in the Northeast (New York and New Jersey) and one high-incidence state in the Midwest (Wisconsin). We used a smartphone application, The Tick App, as a novel survey tool, during spring and summer of 2018. Adaptive human behavior was identified in the relationship between outdoor activities and the use of methods to prevent tick bites. More frequent recreational outdoor activities and gardening (a peridomestic activity) were associated with a 1.4–2.3 times increased likelihood of using personal protective measures to prevent tick bites, when accounting for demographics and previous Lyme diagnosis. Most outdoor activities were more frequently reported by participants from the Midwest (n = 697), representing an older demographic, than the Northeast (n = 396). Participants from the Northeast were less likely to report use of personal protective measures to prevent tick bites, but a larger proportion of participants from the Northeast reported application of environmental pesticides targeting ticks or mosquitoes or other insects on their property (34 % of 279 versus 22 % of 616 participants) and interventions to reduce the presence of peridomestic deer compared to participants from the Midwest (e.g. 20 % of 278 versus 7% of 615 participants reported having a deer proof fence). Participants from the Midwest were more likely to kill rodents on their property (28 % versus 13 %). These differences illustrate the need for further assessment of personal behavior and tick exposure in these two Lyme disease-endemic regions to aid in targeted public health messaging to reduce tick-borne diseases.

Contact Tracing during Coronavirus Disease Outbreak, South Korea, 2020.

We analyzed reports for 59,073 contacts of 5,706 coronavirus disease (COVID-19) index patients reported in South Korea during January 20–March 27, 2020. Of 10,592 household contacts, 11.8% had COVID-19. Of 48,481 nonhousehold contacts, 1.9% had COVID-19. Use of personal protective measures and social distancing reduces the likelihood of transmission.

COVID-19: A global transplant perspective on successfully navigating a pandemic.

The COVID‐19 pandemic has rapidly evolved and changed our way of life in an unprecedented manner. The emergence of COVID‐19 has impacted transplantation worldwide. The impact has not been just restricted to issues pertaining to donors or recipients, but also health‐care resource utilization as the intensity of cases in certain jurisdictions exceeds available capacity. Here we provide a personal viewpoint representing different jurisdictions from around the world in order to outline the impact of the current COVID‐19 pandemic on organ transplantation. Based on our collective experience, we discuss mitigation strategies such as donor screening, resource planning, and a staged approach to transplant volume considerations as local resource issues demand. We also discuss issues related to transplant‐related research during the pandemic, the role of transplant infectious diseases, and the influence of transplant societies for education and disseminating current information.

A Study to Assess the Level of Knowledge Regarding Use of Personal Protective Measures among the Street Sweepers

A Study to Assess the Level of Knowledge Regarding Use of Personal Protective Measures among the Street Sweepers

A Study on Respiratory Morbidities and Pulmonary Functions among Traffic Policemen in Bengaluru City.

Context:Air pollution is a major public health problem in the present Indian cities, due to unplanned urbanization and increased use of vehicles. Traffic policemen, due to the nature of their job and working atmosphere, are more prone to develop respiratory problems such as asthma, chronic obstructive pulmonary disease, rhinitis, recurrent respiratory tract infections, and others.Objectives:The objective was to find out the respiratory morbidities and to assess their pulmonary function using computerized spirometry among traffic policemen in Bengaluru city.Settings and Design:A cross-sectional study was conducted for a period of 6 months (from January 2018 to June 2018) in randomly selected traffic police stations in South Bengaluru, Karnataka.Subjects and Methods:A pretested, semi-structured questionnaire was used to collect information on the demographic profile, duration of exposure, smoking history, allergy/asthma history, and the use of personal protective measures. Pulmonary function test (PFT) was done to assess the lung function using computerized spirometry.Statistical Analysis Used:Data were entered and analyzed using Microsoft Excel 2016 version.Results:A total of 217 traffic policemen were included in the study. The mean duration of working in the traffic department was 5.9 ± 6.6 years (mean ± standard deviation). Among them, 101 (46.5%) used personal protective measures. Allergic rhinitis was reported by 38 (17.5%) individuals, and 28 (12.9%) individuals had chest symptoms (cough and breathing difficulty). Among them, 44 (20.3%) experienced exacerbation of these symptoms at the workplace. Observed mean values of all parameters in the PFT were less than their predicted (expected) values.Conclusions:There was increased burden of respiratory problems and lower lung volumes and flows among traffic policemen.

Borreliosis’ incidence among selected professionals in Poland

Borreliosis, also known as the Lyme disease, can be often characterized with a long-term latency period. Varied symptoms caused by different strains may additionally make it difficult to identify. Delayed diagnosis and treatment can lead to irreversible osteoarticular or neurological changes. In the case of pregnant women the illness can cause developmental changes of the fetus or even lead to miscarriage. The wide base of tick hosts additionally increases the risk of contracting borreliosis by various occupational groups. This publication is aimed at presenting the risk of contracting the Lyme disease among selected professionals in Poland, especially in respect to forest workers, perceived as the highest risk group. By correlating data from many years of disease reports, it is possible to observe the effects of the hitherto use of personal protection measures and to determine the estimated likelihood of the Lyme disease spread among other professional groups.

Causes of accidents at work in the opinions of public sector forestry employees in Poland

The aim of the study was recognition of opinions of forestry employees concerning causes of accidents in forestry, and evaluation of which of the selected demographic characteristics of forestry employees are associated with their opinions concerning causes of occupational accidents. An attempt was also undertaken to answer the question whether there is any relationship between the opinions of forestry employees pertaining to the causes of accidents at work, and observance of the OSH principles concerning the use of protection measures. The survey included 135 forestry employees and conducted by using an author-constructed questionnaire containing items which primarily concerning the causes of accidents at work and the protection measures applied. The opinions of forestry employees pertaining to the causes of accidents were analyzed according to independent variables, such as: workplace, period of employment, age, education level, and an index of the level of the respondents' concern about OSH (index of the use of personal protection measures by the respondents). The significance of differences between the subgroups selected according to the above-mentioned variables was assessed using the chi-square test. Forestry employees most frequently indicated such causes of accidents as the lack of e use of protection equipment (63.7%), bravado and neglecting hazards (63%), as well as entering or staying in a danger zone during tree felling (56.3%). Nearly a half of the respondents (48.1%) mentioned as the cause of accidents the improper and self-willed behaviour of an employee. The respondents additionally mentioned being taken by surprise by an unexpected event (40%), and the inadequate state of machinery, equipment, and vehicles (36.3%). Based on the results of the study concerning the causes of accidents in forestry, it was found that the examined forestry employees show high awareness and knowledge concerning the causes of occupational accidents in forestry. The greatest differences in the way of perceiving the causes of accidents and hazards were observed according to the respondents' period of employment and age. In addition, a relationship was observed between indication by the respondents of specified causes of accidents, and the scope of their use of protection measures.

Community awareness on dengue and practices of mosquito bite prevention in urban residents of a central Indian city, Sagar, Madhya Pradesh

Background: Dengue is an arboviral, mosquito borne illness caused by bite of infected aedes mosquitoes which breed commonly on household water containers like cooler tank, fridge trays and flower pots. Though dengue is non fatal illness but it may lead to deaths from dengue hemorrhagic fever and dengue shock syndrome. The objective of the study was to assess the community awareness regarding dengue and practices primarily being used as personal protection measures against mosquito bites and abolition of household breeding sites of mosquitoes.Methods: A cross sectional observational study done in 5 randomly selected wards of the municipal corporation Sagar. 400 households were studied, selecting 80 houses from each ward randomly. Pretested structured questionnaire was used for interview with the head of family/adult member of the family. The data collected was analysed using SPSS software and chi square test was applied as test of significance.Results: The households studied were mostly (28.2%) of lower middle class (modified B G Prasad scale). the dengue awareness in the community was fair (44.25%) and satisfactory (46.25) in Likert scale. Awareness regarding household breeding sites of mosquitoes was absolute (100%) but the use of personal protective measures was partial (50%).Conclusions: The knowledge and awareness to stop the mosquito breeding, biting should be enhanced and should be turned into action.
