Governments’ economic support for households during the COVID-19 pandemic and consumer confidence

To combat the adverse consequences of the COVID-19 pandemic, governments have implemented various economic policies. This study examines how different types of government economic support for households are associated with consumer confidence. Utilizing data from 35 countries in the Organization for Economic Co-operation and Development for January 2020–October 2021 and applying panel fixed effect and system generalized methods of moments regressions, we show that higher levels of government economic support lead to higher levels of consumer confidence. The results also suggest that government income support for households has a stronger impact than debt/contract relief on consumer confidence during the pandemic in the full sample. Moreover, we find that debt/contract relief is a more effective policy to boost confidence in emerging economies. Finally, COVID-19 fatalities have a significant negative effect on consumer confidence.

University students' experience of online space while engaging in synchronous learning via videoconferencing amidst the pandemic.

The high infectivity and fatality of COVID-19 has changed the mode of higher education from onsite to online. Although many studies investigated the effectiveness and satisfaction of online education, little is known regarding university students' lived experience of online space during synchronous learning via videoconferencing. The present study explored how university students experienced online space when engaging in synchronous learning via videoconferencing platforms during the outbreak of the pandemic. The phenomenological approach was chosen to primarily explore students' experience of online space as well as their experience of embodiment and relations to self and others. Interviews were conducted with nine university students who voluntarily participated to share their experience of online space. Three core themes were generated from the descriptions of experiences provided by the participants. For each core theme, two sub-themes were emerged and described. The analysis of the themes demonstrated that online space was experienced as being separate from home but also inseparable because it was an extension of the comforts of home. This inseparableness is also reflected in the virtual classroom where the rectangular screen presented on the monitor is always shared with everyone in the class. Moreover, online space was perceived as having no transitional space in which spontaneity and new encounters occur. Finally, the presence of self and others was experienced differently in online space due to the participants' choices of being seen or heard using their microphones and cameras. This led to a different sense of togetherness in online space. The insights gained from the study were discussed in relation to considerations for online learning in the post-pandemic era. Based on the emerged themes from the results, the current study concluded that the online space created by technologies cannot be a complete substitute for traditional face-to-face classrooms and suggested possible implications for designing and using online space in university education.

Estimates of COVID-19 deaths in Mainland China after abandoning zero COVID policy.

China witnessed a surge of Omicron infections after abandoning 'zero COVID' strategies on 7 December 2022. The authorities report very sparse deaths based on very restricted criteria, but massive deaths are speculated. We aimed to estimate the COVID-19 fatalities in Mainland China until summer 2023 using the experiences of Hong Kong and of South Korea in 2022 as prototypes. Both these locations experienced massive Omicron waves after having had very few SARS-CoV-2 infections during 2020-2021. We estimated age-stratified infection fatality rates (IFRs) in Hong Kong and South Korea during 2022 and extrapolated to the population age structure of Mainland China. We also accounted separately for deaths of residents in long-term care facilities in both Hong Kong and South Korea. Infection fatality rate estimates in non-elderly strata were modestly higher in Hong Kong than South Korea and projected 987,455 and 619,549 maximal COVID-19 deaths respectively, if the entire China population were infected. Expected COVID-19 deaths in Mainland China until summer 2023 ranged from 49,962 to 691,219 assuming 25-70% of the non-elderly population being infected and variable protection of elderly (from none to three-quarter reduction in fatalities). The main analysis (45% of non-elderly population infected and fatality impact among elderly reduced by half) estimated 152,886-249,094 COVID-19 deaths until summer 2023. Large uncertainties exist regarding potential changes in dominant variant, health system strain and impact on non-COVID-19 deaths. The most critical factor that can affect total COVID-19 fatalities in China is the extent to which the elderly can be protected.

The Impact of COVID-19 Lockdowns on Air Quality: A Systematic Review Study

Background: The purpose of this article was to review the published literature and evaluate the association between air quality/air pollution and the lockdown/stay-at-home orders during COVID-19 pandemic. Our goal is to identify the various environmental factors, such as urban and rural air quality, which were affected by the lockdown during the coronavirus disease (COVID-19) pandemic. Methods: We searched PubMed (2000–2021) for eligible articles using the following: (1) Aerosol[Title/Abstract], AND (2) air quality[Title/Abstract] OR air pollution[Title/Abstract] AND (3) COVID-19[Title/Abstract]. A total of 39 articles were identified through the search conducted in PubMed. We first screened the title and the abstract of those 39 articles for eligibility. A total of 24 articles did not meet the eligibility criteria and were excluded based on the title and the abstract review. The 15 remaining articles were assessed in full text for eligibility and data extraction. After a full-text review, 3 articles were excluded. Finally, a total of 12 selected articles were confirmed for data extraction. Results: Among the 12 studies, 5 articles focused on the effect of the air pollution, fine particulate matter, and air pollutants of COVID-19 pandemic’s lockdown, while 1 article targeted the relationship between the weather/air quality and COVID-19 death rate during lockdown. In addition, 5 papers focused on the association between the environmental factors, air pollution and air quality and COVID-19 mortality rate. Finally, 1 research study paper aimed to study the COVID-19 positivity rate and the effect of air quality during the stay-at-home order or the lockdown which was occurred in March 2020. It is important to note that it has been found that an increase in the average PM2.5 concentration was correlated with a relative increase in the COVID-19 test positivity rate. This explains the increase in the number of COVID cases during the period of the wildfire smoke from August to October 2020 (1). Conclusion: The findings indicate that the COVID-19 lockdown has significant impact on the air quality across the world. The lockdown significantly reduces the air pollutants such as NO2, CO, O3 and Particulate Matter PM2.5 and PM10. This reduction led to a much healthier and safer outdoor air and hence improved the air quality during the lockdown/stay-at-home orders. More research is needed to validate that the air pollutants (NO2, CO, O3, PM2.5 and PM10) have a significant impact on the COVID-19 mortality and fatality rates.

COVID-19 infection rate but not severity is associated with availability of greenness in the United States

Human exposure to greenness is associated with COVID-19 prevalence and severity, but most relevant research has focused on the relationships between greenness and COVID-19 infection rates. In contrast, relatively little is known about the associations between greenness and COVID-19 hospitalizations and deaths, which are important for risk assessment, resource allocation, and intervention strategies. Moreover, it is unclear whether greenness could help reduce health inequities by offering more benefits to disadvantaged populations. Here, we estimated the associations between availability of greenness (expressed as population-density-weighted normalized difference vegetation index) and COVID-19 outcomes across the urban–rural continuum gradient in the United States using generalized additive models with a negative binomial distribution. We aggregated individual COVID-19 records at the county level, which includes 3,040 counties for COVID-19 case infection rates, 1,397 counties for case hospitalization rates, and 1,305 counties for case fatality rates. Our area-level ecological study suggests that although availability of greenness shows null relationships with COVID-19 case hospitalization and fatality rates, COVID-19 infection rate is statistically significant and negatively associated with more greenness availability. When performing stratified analyses by different sociodemographic groups, availability of greenness shows stronger negative associations for men than for women, and for adults than for the elderly. This indicates that greenness might have greater health benefits for the former than the latter, and thus has limited effects for ameliorating COVID-19 related inequity. The revealed greenness-COVID-19 links across different space, time and sociodemographic groups provide working hypotheses for the targeted design of nature-based interventions and greening policies to benefit human well-being and reduce health inequity. This has important implications for the post-pandemic recovery and future public health crises.

Spatio-temporal Analysis of COVID-19: A Global Study

Background: COVID-19 is an international public health emergency in the world. Objectives: The aim of the present study is to determine the geographic pattern and temporal trend of Coronavirus disease 2019 incidence, fatality, and recovery rates worldwide. Methods: The present ecological study is a mixed exploratory study. The study population included Patients with COVID-19, recovered individuals, and deaths from COVID-19 from October 1, 2019, until June 30, 2021, worldwide. Descriptive analysis included the calculation cumulative incidence rate (CIR), case fatality rate (CFR), and case recovery rate (CRR) of COVID-19. Global Moran's I and Anselin Local Moran's I tests were used for spatial analysis. The joinpoint regression analysis was used to examine the time trend by ArcGIS, Joinpoint, and SPSS software. Results: The average cumulative incidence rate was 1077 in 106 individuals; also, the average case recovery rate and average case fatality rate were %72.81 and %3.21, respectively. Global Moran's I index measured for CIR was 0.159. The results of Anselin's local Moran's I, high-high cluster, consists of some countries in South America and in southern and Western Europe and central and western Asia. The temporal trend of changes in the incidence rate and CRR of COVID-19 were incremental, and the average annual percentage change from October 2019 to June 2021 increased by 44.4% and 3.2%, respectively (P < 0.001), but CFR decreased by -0.3% and was not significant (P > 0.05). Conclusions: As regards the specific spatial pattern of fatality and recovery rate of COVID-19, it seems essential to consider spatial conditions and environmental factors which are related to the incidence and fatality of COVID-19 in different regions, as well as the necessity of upgrading the care system in high-risk areas, in order to have better management and control of the pandemic and optimal function in early diagnosis, proper treatment, and high vaccination coverage.

Obstacles of Handling COVID-19 Outbreak among Primary Health Care Nurses in Indonesia

The rise in COVID-19 cases and fatalities indicates that nurses working in primary health care face certain challenges in administering treatment and preventative measures. Identify the obstacles faced by the nurses of primary health care in their efforts to conduct prevention and treatment of the COVID-19 outbreak in Bandung, Indonesia. Correlational descriptive quantitative design with a survey approach was employed in this research. Total sampling was used to collect 120 nurses that made up the study's sample. The findings showed that nurses experienced high obstacles 58 nurses (48.3%) in carrying out tracing tasks, 61 nurses (50.8%) in implementing monitoring tasks, 34 nurses (28.3%) in carrying out education and counseling tasks, and 60 nurses in the duty of referral selection. Multivariate analysis indicated nurses' updating knowledge of monitoring task difficulties is the most crucial determinant with a p-value (p = 0.038). In carrying out nursing duties during the pandemic, updating knowledge is very useful for breaking the chain of transmission and handling pandemics in general. Nurses at PHC should improve their knowledge and handling skills related to the pandemic by attending training and seminars related to handling the COVID-19 outbreak.

Factors associated with COVID-19 fatality among patients admitted in Mashonaland West Province, Zimbabwe 2020-2022: a secondary data analysis

Introduction: approximately 15% of COVID-19 patients develop symptoms necessitating admission. From 2020 to 2022, Mashonaland West Province had an institutional case fatality rate of 23% against a national rate of 7%. Therefore, we evaluated the COVID-19 admissions in the province to determine the factors associated with COVID-19 mortality.

Longstanding Rural-Urban Disparities Exacerbated by COVID-19: The Experiences of Older Residents in West Texas: Lessons Learned

Purpose: The primary objective of this study was to examine differences in COVID-19 testing, diagnosis, symptoms, preventive measures, and healthcare resources and services between urban- and rural-dwelling older adults of the West Texas region. Methods: Data from surveys of 303 adult urban and rural residents (>40 years old) between June 2020 and January 2021 were conducted. County-level data from the Texas Department of State Health Services (TDSHS) were analyzed for the period between March 2020 and February 2021. Findings: County-level data from TDSHS revealed greater access to COVID-19 testing and higher case numbers yet lower COVID-19 fatalities among urban residents. On the contrary, rural counties had fewer overall COVID-19 cases, less access to COVID-19 testing, and higher COVID-19 fatalities. Conclusion: The COVID-19 pandemic exasperated the long-standing healthcare disparities documented between rural and urban neighborhoods, resulting in devastating consequences in rural areas suffering from poor healthcare infrastructure. Findings revealed disparities in COVID-19 experiences among urban and rural communities, which highlight the need for strategies aimed at improving healthcare access in rural areas through telemedicine and other innovative approaches.

Estimating Sars-Cov-2 Infections and Associated Changes in Covid-19 Severity and Fatality

Estimating Sars-Cov-2 Infections and Associated Changes in Covid-19 Severity and Fatality

PS-BPC10-8: POST-VACCINATION SARS-COV-2 IGG ANTIBODY TITER IN DIALYSIS PATIENTS

Background: Dialysis patients have a higher COVID-19 fatality rate than the general population and are priority candidates for SARS-CoV-2 vaccination. However, dialysis patients are immunocompromised, suggesting that they may develop a less immune response to COVID-19 vaccination than healthy individuals. Objective and Methods: A total of 358 hemodialysis patients who were twice-vaccinated with BNT162b2 were included. SARS-CoV-2 IgG antibody titer was measured within 7 days to 1 month, 1∼2 months, and 3∼4 months after the second vaccination, and factors influencing antibody titer were statistically investigated. SARS-CoV-2 IgG measurement was performed using SARS-CoV-2 IgG II Quant Reagent (Abbott), which is a reagent to quantitatively measure IgG antibodies against the receptor-binding domain of SARS-CoV-2 spike protein. Results: The patients were 240 males (67%) and 118 females, ranging from 37 to 95 years old, with a median age of 70 years. Causes of kidney failure were diabetes mellitus in 35.2%, hypertensive kidney disease in 7.3%, glomerular disease in 30.5%, and polycystic kidney disease in 4.5% of the patients. Comorbidities were hypertension in 64.3% and diabetes in 48.9%. Steroids or immunosuppressive drugs were used in 9% of the patients. SARS-CoV-2 IgG antibody titers at 7 days to 1 month, 1 to 2 months, and 3 to 4 months (median 10, 42, and 98 days) after the second vaccination have the median of 4092 AU/mL(with interquartile range: 1354, 7592), 2199 (927, 4692), and 789 (323, 1559), respectively. Post-vaccination SARS-CoV-2 IgG titers were significantly correlated with Kt/V, the presence of autoimmune diseases, the use of steroids or immunosuppressive drugs, malignancy treatment, and serum albumin and hemoglobin levels. Multivariate analysis showed that the factors that decreased post-vaccination SARS-CoV-2 IgG titer were the use of steroids and immunosuppressive drugs, the presence of malignant tumors under treatment, and hypoalbuminemia. Conclusion: Compared to healthy subjects in previous reports, dialysis patients had lower SARS-CoV-2 IgG titers after COVID-19 vaccination, suggesting that the vaccine may not be sufficiently effective. In addition, SARS-CoV-2 IgG titers are likely to be even lower in patients at high risk for decreased immune response due to medications or comorbidities. Additional vaccination may be essential for hemodialysis patients who are expected to have low SARS-CoV-2 IgG titers.

The Impact of Economic Freedom on the COVID-19 Fatality Rate

The Impact of Economic Freedom on the COVID-19 Fatality Rate

U.S. COVID-19 Policy in 2023 and its Consequences

Economic pressures combined with anti-science politics have led to the termination of COVID-19 safety protocols in the United States (US). Although the epidemiology and virology of COVD-19 have not changed since its emergence in late 2019, intentional, consistent strategies with demonstrated efficacy for containment of the pandemic have been abandoned. Diminished media coverage of COVID-19 contributes to the popular notion that the pandemic is “over.” COVID-19 thus remains uncontained in the US. The number of US COVID-19 fatalities remains the highest in the world, and continues to grow. Beyond the negative consequences for public health and pandemic management, the confabulation of politics and science has also produced growing political tensions, with the emergence of socially regressive legislation in states historically invested in the anti-science agenda as applied to COVID-19. Recommendations are made for consistent messaging and policy from government agencies to improve management of the COVID-19 pandemic, and unify the public in acceptance of science-based interventions and attitudes.

Health Expenditure and Covid-19 Mortality Rate: The Role of Corruption

a sample consisting of 119 countries all around the world. The study uses three representations of corruption variables; utilizes a dataset from International Country Risk Guide ICRG. These representations are the country’s inherent corruption, the country’s ongoing corruption, and the country’s corruption and expenditure effects during Covid. The main finding is that corruption positively contributes to a higher Covid-19 fatality rate through inherent corruption, ongoing corrupt activities, and the collective role of corruption and government spending in Covid-19 mortality. Thus, countries pay the cost of their own corruption financially and physically.

Impact of COVID-19 on Antenatal Care in Jeddah, Saudi Arabia

Background: The severe acute respiratory syndrome coronavirus 2, which is what causes the Covid-19 pandemic's high morbidity and fatality rates, is ubiquitous in the population. Additionally, pregnancy increases the risk of unfavourable obstetric and neonatal outcomes from many respiratory virus infections due to the systemic effects of the physiological and immunologic changes that are common throughout pregnancy. So, the objective of our research was to evaluate how a coronavirus-19 pandemic will affect antenatal care in Jeddah, Saudi Arabia, in 2022.
 Methods: This is a cross-sectional study was conducted between 2021-2022 in Jeddah, Saudi Arabia among 202 women who were pregnant during the Coronavirus pandemic and had no previous Covid-19 infection. Data was collected by an online survey, the data were obtained, and different statistical tests were used for analysis by using SPSS, version 23.
 Results: The results revealed that most patients had filmed sonar or television more than twice (78.2%). and the extent of patients visiting the obstetrician and gynaecologist to follow up the pregnancy for more than 8 times of 47%. Moreover, the bulk of participants 89.6% did not have complications during pregnancy. Majority of the participants 76.2% their mental state was not better than usual and only 4% had suicide thoughts. (45.5%) decreased their exercise activity. A significant relationship was found between thinking of hurting the self and worrying about contracting during pregnancy and between mood and thinking of changing the place where intending to give birth. Women with high educations were significantly correlated with the concerns of Covid-19 and more commitment of the quarantine instructions, while who didn’t work were significant related to have concerns of Covid-19 than who work and less commitment to quarantine instructions.
 Conclusion: Although the good antenatal care during the covid19 pandemic in Jeddah, Saudi Arabia, the majority of pregnant women had impact on their mental health and had concerns of Covid-19. Thus, the research suggests providing pandemic related information to pregnant women and enhancing the trust between the caregiver and the patients.

SARS-CoV-2 infection in patients with melanoma: results of the Spanish Melanoma Group registry.

The Spanish Melanoma Group (GEM) developed a national registry of patients with melanoma infected by SARS-CoV-2 ("GRAVID"). The main objective was to describe the COVID-19 fatality rate in patients with melanoma throughout the pandemic, as well as to explore the effect of melanoma treatment and tumor stage on the risk of COVID-19 complications. These are the final data of the register, including cases from February 2020 to September 2021. One hundred-fifty cases were registered. Median age was 68years (range 6-95), 61 (40%) patients were females, and 63 (42%) patients had stage IV. Thirty-nine (26%) were on treatment with immunotherapy, and 17 (11%) with BRAF-MEK inhibitors. COVID-19 was resolved in 119 cases, including 85 (57%) patients cured, 15 (10%) that died due to melanoma, and 20 (13%) that died due to COVID-19. Only age over 60years, cardiovascular disorders, and diabetes mellitus increased the risk of death due to COVID-19, but not advanced melanoma stage nor melanoma systemic therapies. Three waves have been covered by the register: February-May 2020, August-November 2020, and December 2020-April 2021. The first wave had the highest number of registered cases and COVID-19 mortality. Tumor stage or melanoma treatments are non-significant prognostic factors for COVID-19 mortality. During the pandemic in Spain there was a downward trend in the number of patients registered across the waves, as well as in the severity of the infection. NCT04344002.

Biochemical and hematological factors associated with COVID-19 severity among Gabonese patients: A retrospective cohort study.

The COVID-19 disease presents a large range of clinical manifestations and includes asymptomatic, mild, and severe cases. The level of severity is related to parameters associated with immunity, genetics, and biochemistry. Africa shows one of the lowest COVID-19 fatality rates but very few data on the biochemical markers of COVID-19 in patients and the factors associated with disease severity are available for the continent. In Gabon, the COVID-19 fatality rate is only 0.63% but almost no data on biomarkers in COVID-19 patients have been published. Both the number of COVID-19 cases and the mortality rate reported in Africa in general, and in Gabon in particular, are lower than in non-African countries. As such, understanding the factors associated with disease severity in Gabonese patients is a crucial step to better understand the disease in the African context and prepare for future COVID-19 waves and other epidemics of emerging diseases. Here, we compared biochemical and hematological markers among 753 Gabonese COVID-19 patients with asymptomatic (184/753), mild/moderate (420/753), and severe/critical (149/753) forms of the disease using an Analysis of Variance (ANOVA) or a Kruskal-Wallis (KW) test. We modeled these parameters together with comorbidities, age, and sex to predict factors associated with disease severity by using a "binomial generalized linear model" utilizing the "package" stats of R software version 4.0.2. Our results showed that almost all the biochemical and hematological parameters (except creatinine, phosphorus, D-dimers, platelets, and monocytes) varied according to disease severity. However, age and the dysfunction of organs like the kidney, liver, and lung together with the decrease of electrolytes (chloride, potassium, and sodium) are the best predictors of disease severity in Gabonese patients.

A study protocol to explore and implement community-based point-of-care COVID-19 testing for women who use drugs in Baltimore, Maryland: The CARE study.

Women who use drugs (WWUD) experience structural vulnerabilities (e.g., housing, food insecurities) and comorbidities that elevate their susceptibility to more severe COVID-19 symptoms or fatality compared to similarly-aged women who do not use illicit drugs. Testing is a cornerstone of effective COVID prevention, however, entrenched barriers to healthcare utilization means that WWUD may have diminished accessing to COVID testing. The CARE (COVID Action Research Engagement) study first examines predisposing and enabling factors that predict COVID testing uptake over six months (baseline, 3-, and 6-month follow-up) among a cohort of WWUD (N = 250) in Baltimore, Maryland, providing a nuanced and holistic understanding of how to meaningfully engage WWUD in COVID testing. Then, point-of-care COVID testing will be implemented on a mobile outreach van affiliated with a local community-based organization primarily serving WWUD; anonymous surveys of mobile outreach guests (N = 100) will assess feasibility and acceptability of this integrated testing. The study is grounded in the Behavioral Model for Vulnerable Populations and the Theoretical Framework of Acceptability. We hypothesize that point-of-care COVID testing integrated into a low-barrier harm reduction service, such as a mobile outreach program, will be an enabling environment for COVID testing uptake in part by reducing structural impediments to testing and will be highly feasible and acceptable to participants. Strengths, limitations, and plans for results dissemination are discussed.

Spatial-temporal differences of COVID-19 vaccinations in the U.S.

Although the disparities in COVID-19 outcomes have been proved, they have not been explicitly associated with COVID-19 full vaccinations. This paper examines the spatial and temporal patterns of the county-level COVID-19 case rates, fatality rates, and full vaccination rates in the United States from December 24, 2020 through September 30, 2021. Statistical and geospatial analyses show clear temporal and spatial patterns of the progression of COVID-19 outcomes and vaccinations. In the relationship between two time series, the fatality rates series was positively related to past lags of the case rates series. At the same time, case rates series and fatality rates series were negatively related to past lags of the full vaccination rates series. The lag level varies across urban and rural areas. The results of partial correlation, ordinary least squares (OLS) and Geographically Weighted Regression (GWR) also confirmed that the existing COVID-19 infections and different sets of socioeconomic, healthcare access, health conditions, and environmental characteristics were independently associated with COVID-19 vaccinations over time and space. These results empirically identify the geographic health disparities with COVID-19 vaccinations and outcomes and provide the evidentiary basis for targeting pandemic recovery and public health mitigation actions.

Hypertension in Associated with COVID-19

The novel coronavirus infection (COVID-19), now a worldwide public health concern is associated with varied fatality. Patients with chronic underlying conditions like hypertension have shown worst outcomes. Hypertension is a multifactorial disease and a public health burden, as it is a risk factor for diseases like stroke, coronary artery disease, and heart failure. As one of the most important public health problems in the 21st century, hypertension affects more than one billion individuals worldwide. Hypertension is a common comorbidity in COVID-19 patients. However, the association of hypertension with the severity and fatality of COVID-19 remain unclear. Hypertension is a major risk factor regarding the severity and fatality of COVID-19, and the RAAS plays an important role in COVID-19 infection since SARS-CoV-2 can lead to a dysregulation of the system by reducing the ACE2 expression. Hypertension may also affect the prognosis of COVID-19 illness. The severity rate of COVID-19 in hypertensive patients was much higher than in non-hypertensive cases. A systematic literature search was conducted using several databases on studies that assess hypertension and outcome in COVID-19. Composite of poor outcome, comprising of mortality, severe COVID-19, acute respiratory distress syndrome (ARDS), need for intensive care unit (ICU) care and disease progression were the outcomes of interest. Authors independently reviewed some titles, abstracts and read full-texts of articles to identify potentially eligible studies to decide about final inclusions. This systematic review was conducted based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement. We used six different databases: Pubmed, Clinical Key, Science Direct, Cochrane Library, Springer Link and Oxford Academic. A total of 2731 articles from the databases were identified, we got three articles that fulfill the criteria. We excluded the other studies by reading the title, abstract, and full text assessment. Hypertension was associated with the severity and mortality of COVID-19 illness. Hypertension was also independently associated with a significantly increased risk of critical COVID-19 and inhospital mortality of COVID-19.
