Coronavirus disease 2019 (Covid-19) poses an important occupational health risk to health workers (HWs) that has attracted global scrutiny. To date, several thousand HWs globally have been reported as infected with the severe acute respiratory syndrome coronavirus 2 virus that causes the disease. It is therefore a public health priority for policymakers to understand risk factors for this vulnerable group to avert occupational transmission. A rapid review was carried out on 20 April 2020 on Covid-19 risk factors among HWs in PubMed, Google Scholar, and EBSCOHost Web (Academic Search Complete, CINAHL Complete, MEDLINE with Full Text, CINAHL with Full Text, APA PsycInfo, Health Source—Consumer Edition, Health Source: Nursing/Academic Edition) and WHO Global Database. We also searched for preprints on the medRxiv database. We searched for reports, reviews, and primary observational studies (case control, case cross-over, cross-sectional, and cohort). The review included studies conducted among HWs with Covid-19 that reported risk factors irrespective of their sample size. Eleven studies met the inclusion criteria. Lack of personal protective equipment, exposure to infected patients, work overload, poor infection control, and preexisting medical conditions were identified as risk factors for Covid-19 among HWs. In the context of Covid-19, HWs face an unprecedented occupational risk of morbidity and mortality. There is need for rapid development of sustainable measures that protect HWs from the pandemic.

Background and objective:To provide good health and well-being as established by the Sustainable Development Goal(SDG)3,access to digital technologies can act as conduits to achieve such progress in a population.As guided by the World Health Organization,antenatal care(ANC)attendance is one of the measures promoted to curtail the global health burden of maternal and infant mortality.ANC services are seldom utilized to their full potential in Zimbabwe.This study explores if any of the women's digital technology characteristics were associated with antenatal care visits.Methods:The study analyzed population-based cross-sectional data with a subsample of 1 932 women aged 15-49 years from the 2019 Zimbabwe Multiple Indicator Cluster Survey.Test of associations with chi-square test,bivariate,and multivariate multinomial logistic regression analyses were used to examine the predictors of adequate(4-7)and optimal(≥ 8)ANC visits relative to undesirable(1-3)antenatal care visits among women who had given births 2 years before the survey.Results:The results indicate that 64.5％(1246/1 932)of the women attained adequate ANC while about 9.8％(189/1 932)attained optimal ANC.Reading a newspaper/magazine at least once a week(odds ratio[OR]1.73,β'=0.551,t=2.030,P=0.043)and watching television at least once a week(OR 1.72,β'=0.545,t=2.454,P=0.015),listening to the radio less than once a week(OR 1.28,β'=0.247,t=1.750,P=0.080),and owning a mobile phone(OR 1.48,β'=0.394,t=3.020,P=0.003)were positively associated with adequate ANC.Optimal ANC was significantly associated with women being able to read a newspaper at least once a week(OR 2.93,β'=1.074,t=3.120,P=0.002),listen to the radio less than once a week(OR 2.07,β'=0.73,t=2.700,P=0.007)and have ownership of a mobile phone(OR 1.88,β'=0.631,t=2.620,P=0.009).Conclusion:Access to a newspaper,radio,television,and mobile phone were important predictors of a woman's ability to achieve her ANC attendance.Policies to improve the knowledge of ANC packages can be facilitated using digital technology to achieve adequate and preferably optimal ANC in Zimbabwe.It is important to improve digital infrastructure to support digital technologies in providing ANC services.

Globally,there have been multiple public health emergencies in recent decades.High rates of morbidity,occa-sionally mortality,and economic instability are usually associated with pandemics.One of the epidemics that has significantly increased morbidity and mortality worldwide is the human immunodeficiency virus(HIV)and acquired immune deficiency syndrome(AIDS)pandemic.HIV has a disproportionately negative impact on key populations.Strong leadership,effective communication,and sound science are necessary for public health emer-gency(PHE)responses to be successful.These three PHE response pillars are also essential for bridging the HIV response gap among key populations in the setting of restrictive laws.In this review,we explored the importance of these three pillars of successful PHEs responses,and how they are essential to closing the gap in the HIV response among key populations.Leaders must make decisions and instil a sense of authority in the populace during PHEs to foster trust and confidence.Leaders should base their choices on scientific evidence.Effective communication during PHEs should be proactive,polite,imaginative,innovative,and constructive.To address gaps in the HIV response among key populations,leaders must create a supportive environment for effective communication and scientific research,communication should be used to raise awareness of HIV and to dispel stigma and discrimination,while science should provide evidence of efficacy and effectiveness of interventions among key populations.

Health care workers (HCWs) are more than ten times more likely to be infected with coronavirus infectious disease 2019 (COVID-19) than the general population, thus demonstrating the burden of COVID-19 among HCWs. Factors that expose HCWs to a differentially high-risk of COVID-19 acquisition are important to elucidate, enable appropriate public health interventions to mitigate against high risk and reduce adverse outcomes from the infection. We conducted a systematic review and meta-analysis to summarize and critically analyze the existing evidence on SARS-CoV-2 risk factors among HCWs. With no geographical limitation, we included studies, in any country, that reported (i) the PCR laboratory diagnosis of COVID-19 as an independent variable (ii) one or more COVID-19 risk factors among HCWs with risk estimates (relative risk, odds ratio, or hazard ratio) (iii) original, quantitative study design, and published in English or Mandarian. Our initial search resulted in 470 articles overall, however, only 10 studies met the inclusion criteria for this review. Out of the 10 studies included in the review, inadequate/lack of protective personal equipment, performing tracheal intubation, and gender were the most common risk factors of COVID-19. Based on the random effects adjusted pooled relative risk, HCWs who reported the use of protective personal equipment were 29% (95% CI: 16% to 41%) less likely to test positive for COVID-19. The study also revealed that HCWs who performed tracheal intubations were 34% (95% CI: 14% to 57%) more likely to test positive for COVID-19. Interestingly, this study showed that female HCWs are at 11% higher risk (RR 1.11 95% CI 1.01–1.21) of COVID-19 than their male counterparts. This article presents initial findings from a living systematic review and meta-analysis, therefore, did not yield many studies; however, it revealed a significant insight into better understanding COVID-19 risk factors among HCWs; insights important for devising preventive strategies that protect them from this infection.
