Healthcare Workers Infection Rate in the Era of Coronavirus Disease 2019 - in Tertiary Teaching Hospital

BACKGROUND: Healthcare workers (HCWs) are at the frontline defense against coronavirus disease 2019 (COVID-19) pandemic. AIM: The study aimed to describe the characteristics and appraise potential risk factors of COVID-19 transmission among HCWs who tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in one of Cairo University Hospitals. METHOD: Cross-sectional descriptive analysis of confirmed polymerase chain reaction (PCR) positive versus negative cases for COVID-19. RESULTS: Through March–June 2020, (145/846; 17%) suspected HCWs were tested for COVID-19 by PCR; out of them (70/145; 48.3%) were confirmed as positive, these positive cases represented (70/846; 8.3%) of all HCWs of the hospital. About 33% of confirmed COVID-19 positive HCWs acquired the infection from the healthcare while only (13/70; 19%) from community settings, and no clear exposure data were identified in (34/70; 48%) of cases. Most of symptomatic cases showed a positive PCR test for SARS-CoV-2 versus asymptomatic cases, p < 0.001. There was no statistical significance regarding gender, age, presence of comorbidity, workload or the type of acquisition. CONCLUSION: HCWs are at an increased risk of COVID-19 infection at the workplace. Strict implementation of infection control measures is of crucial role in preventing transmission of COVID-19 infection in health-care settings.

ObjectiveTo study the SARS-CoV-2 infection rate among hospital healthcare workers after the first wave of the COVID-19 pandemic, and provide more knowledge in the understanding of the relationship between infection, symptomatology and source of infection.DesignA cross-sectional study in healthcare workers.SettingNorthern Limburg, the Netherlands.ParticipantsAll employees of VieCuri Medical Center (n=3300) were invited to enrol in current study. In total 2507 healthcare workers participated.InterventionBetween 22 June 2020 and 3 July 2020, participants provided venous blood samples voluntarily, which were tested for SARS-CoV-2 antibodies with the Wantai SARS-CoV-2 Ig total ELISA test. Work characteristics, exposure risks and prior symptoms consistent with COVID-19 were gathered through a survey.Main outcome measureProportion of healthcare workers with positive SARS-CoV-2 serology.ResultsThe overall seroprevalence was 21.1% (n=530/2507). Healthcare workers between 17 and 30 years were more likely to have SARS-CoV-2 antibodies compared with participants >30 years. The probability of having SARS-CoV-2 antibodies was comparable for healthcare workers with and without direct patient (OR 1.42, 95% CI 0.86 to 2.34) and COVID-19 patient contact (OR 1.62, 95% CI 0.80 to 3.33). On the contrary, exposure to COVID-19 positive coworkers (OR 1.83, 95% CI 1.15 to 2.93) and household members (OR 6.09, 95% CI 2.23 to 16.64) was associated with seropositivity. Of those healthcare workers with SARS-CoV-2 antibodies, 16% (n=85/530) had not experienced any prior COVID-19-related symptoms. Only fever and anosmia were associated with seropositivity (OR 1.90, 95% CI 1.42 to 2.55 and OR 10.51, 95% CI 7.86 to 14.07).ConclusionsHealthcare workers caring for hospitalised COVID-19 patients were not at an increased risk of infection, most likely as a result of taking standard infection control measures into consideration. These data show that compliance with infection control measures is essential to control secondary transmission and constrain the spread of the virus.

ObjectiveTo determine the rates of asymptomatic viral carriage and seroprevalence of SARS-CoV-2 antibodies in healthcare workers.DesignA cross-sectional study of asymptomatic healthcare workers undertaken on 24/25 April 2020.SettingUniversity Hospitals Birmingham NHS Foundation Trust (UHBFT), UK.Participants545 asymptomatic healthcare workers were recruited while at work. Participants were invited to participate via the UHBFT social media. Exclusion criteria included current symptoms consistent with COVID-19. No potential participants were excluded.InterventionParticipants volunteered a nasopharyngeal swab and a venous blood sample that were tested for SARS-CoV-2 RNA and anti-SARS-CoV-2 spike glycoprotein antibodies, respectively. Results were interpreted in the context of prior illnesses and the hospital departments in which participants worked.Main outcome measureProportion of participants demonstrating infection and positive SARS-CoV-2 serology.ResultsThe point prevalence of SARS-CoV-2 viral carriage was 2.4% (n=13/545). The overall seroprevalence of SARS-CoV-2 antibodies was 24.4% (n=126/516). Participants who reported prior symptomatic illness had higher seroprevalence (37.5% vs 17.1%, χ2=21.1034, p<0.0001) and quantitatively greater antibody responses than those who had remained asymptomatic. Seroprevalence was greatest among those working in housekeeping (34.5%), acute medicine (33.3%) and general internal medicine (30.3%), with lower rates observed in participants working in intensive care (14.8%). BAME (Black, Asian and minority ethnic) ethnicity was associated with a significantly increased risk of seropositivity (OR: 1.92, 95% CI 1.14 to 3.23, p=0.01). Working on the intensive care unit was associated with a significantly lower risk of seropositivity compared with working in other areas of the hospital (OR: 0.28, 95% CI 0.09 to 0.78, p=0.02).Conclusions and relevanceWe identify differences in the occupational risk of exposure to SARS-CoV-2 between hospital departments and confirm asymptomatic seroconversion occurs in healthcare workers. Further investigation of these observations is required to inform future infection control and occupational health practices.

Increased Risk

Healthcare workers (HCWs) are at increased risk of infection by the virulent severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Though data exist on the positivity rate of the SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) test as well as COVID-19-related deaths amongst HCWs in South Africa, the overall infection rate remains underestimated by these indicators. It is also unclear whether the humoral immune response after SARS-CoV-2 infection offers durable protection against reinfection. This study will assess the SARS-CoV-2 seroprevalence amongst HCWs in the Eastern Cape (EC) and examine the longitudinal changes (rate of decay) in the antibody levels after infection in this cohort. Using a multi-stage cluster sampling of healthcare workers in selected health facilities in the EC, a cross-sectional study of 2250 participants will be recruited. In order to assess the community infection rate, 750 antenatal women in the same settings will be recruited. Relevant demographic and clinical characteristics will be obtained by a self-administered questionnaire. A chemiluminescent microparticle immunoassay (CMIA) will be used for the qualitative detection of IgG antibodies against SARS-CoV-2 nucleocapsid protein. A nested cohort study will be conducted by performing eight-weekly antibody assays (X2) from 201 participants who tested positive for both SARS-CoV-2 RT-PCR and serology. Logistic regression models will be fitted to identify the independent risk factors for SARS-CoV-2 infection. The cumulative SARS-CoV-2 infection rate and infection fatality rate among the frontline HCWs will be estimated. In addition, the study will highlight the overall effectiveness of infection prevention and control measures (IPC) per exposure sites/wards at the selected health facilities. Findings will inform the South African Department of Health’s policies on how to protect HCWs better as the country prepares for the second wave of the SARS-CoV pandemic.

Objective: To estimate the percentage of individuals infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) over time in the community in England and to quantify risk factors. Design: Repeated cross-sectional surveys of population-representative households with longitudinal follow-up if consent given. Setting: England. Participants: 34,992 Individuals aged 2 years and over from 16,722 private residential households. Data were collected in a pilot phase of the survey between 26 April and 28 June 2020. Main outcome measures: Percentage of individuals in the community testing positive for SARS-CoV-2 RNA using throat and nose swabs. Individuals were asked about any symptoms and potential risk factors. Results: The percentage of people in private-residential households testing positive for SARS-CoV-2 reduced from 0.32% (95% credible interval (CrI) 0.19% to 0.52%) on 26 April to 0.08% (95% CrI 0.05% to 0.12%) on 28 June, although the prevalence stabilised near the end of the pilot. Factors associated with an increased risk of testing positive included having a job with direct patient contact (relative exposure (RE) 4.06, 95% CrI 2.42 to 6.77)), working outside the home (RE 2.49, 95% CrI 1.39 to 4.45), and having had contact with a hospital (RE 2.20, 95% CrI 1.09 to 4.16 for having been to a hospital individually and RE 1.95, 95% CrI 0.81 to 4.09 for a household member having been to a hospital). In 133 visits where individuals tested positive, 82 (61%, 95% CrI 53% to 69%) reported no symptoms, stably over time. Conclusion: The percentage of SARS-CoV-2 positive individuals declined between 26 April and 28 June 2020. Positive tests commonly occurred without symptoms being reported. Working outside your home was an important risk factor, indicating that continued monitoring for SARS-CoV-2 in the community will be essential for early detection of increases in infections following return to work and other relaxations of control measures.

Abstract Background: Many healthcare systems initiated rapid training with COVID-19 simulations for their healthcare workers (HCWs) to build surge capacity and optimize infection control measures. This study aimed to describe COVID-19 simulation drills in international healthcare centers. Methods: This is a cross-sectional survey among simulation team leaders and HCWs, based on each center's debriefing reports from simulation centers from 30 countries in all WHO regions where COVID-19 simulation drills were conducted. The primary outcome measures were the COVID-19 simulations' characteristics, outcomes, facilitators, obstacles, and challenges encountered during the simulation sessions. Results: Invitation was sent to 500 simulation team leaders and HCWs, and 343 responded. Those who completed the study comprised 121 participants: 62.8% females; 56.2% physicians; 41.3% from East Mediterranean (EMRO) countries; 25.6% from Southeast Asian countries (SERO); and 12.4% from Europe. The frequency of simulation sessions was monthly (27.1%), weekly (24.8%), twice weekly (19.8%), or daily (21.5%). Among participants, 55.6% reported the team's full engagement in the simulation sessions. The average session length was 30–60 minutes. The most commonly reported debriefing leaders were ICU staff, simulation lab staff, and E.R. facilitators, and the least common were infection control staff. A total of 80% reported "a lot" to "a great improvement" in terms of clinical preparedness after simulation sessions, and 70% were satisfied with the COVID-19 simulation sessions and thought they were better than expected. Most of the perceived issues reported were related to infection control measures, followed by team dynamics, logistics, and patient transport issues. Conclusion: Simulation centers team leaders and HCWs reported positive feedback on COVID-19 simulation sessions. The presence of multiprofessional personnel during drills is warranted. These drills are a valuable tool for rehearsing safe dynamics of HCWs on the frontline of COVID-19.Trial registration: Not applicable.

Background Coronavirus disease (COVID-19) is a highly infectious disease caused by an RNA virus named SARS CoV2. The increased risk of infection by this virus among dental students necessitates updated knowledge and highlights their important role in preventing and controlling its transmission. Objective: This study aims to assess knowledge, perceptions, and attitudes regarding COVID-19 and infection control measures among dental students in Saudi Arabia. Methods: A cross-sectional study was conducted among dental students in different Saudi universities using an online self-administered questionnaire. It gathered data on students’ demographic information, knowledge of COVID-19 and infection control measures, risk perception and attitudes toward the disease, and their preparedness for treating infected patients. Results: A total of 327 dental students responded to the questionnaire. Of these students, 92.4% had received training in infection control in dental practice, but only 24.2% had attended training regarding COVID-19. The majority of students had adequate knowledge regarding the modes of transmission and the common symptoms of COVID-19, with statistically significant total mean knowledge scores among students in different academic years (p<0.05). A large percentage of the students (92.7%) agreed that the use of rubber dams or high-volume saliva ejectors could reduce the possibility of transmitting infection. However, 58.4% of the students disagreed that intraoral dental radiographs should be avoided to reduce the possibility of transmitting infection. Conclusion: Although knowledge of and risk perception concerning COVID-19 among students is good, additional training sessions integrating recent international guidelines for infection control are required to update their knowledge and achieve safe dental practice.

Healthcare workers (HCWs) are at increased risk of latent tuberculosis (TB) infection (LTBI) and TB disease.We conducted an updated systematic review of the prevalence and incidence of LTBI in HCWs in low- and middle-income countries (LMICs), associated factors, and infection control practices. We searched MEDLINE, Embase and Web of Science (January 1, 2005–June 20, 2017) for studies published in any language. We obtained pooled estimates using random effects methods and investigated heterogeneity using meta-regression.85 studies (32 630 subjects) were included from 26 LMICs. Prevalence of a positive tuberculin skin test (TST) was 14–98% (mean 49%); prevalence of a positive interferon-γ release assay (IGRA) was 9–86% (mean 39%). Countries with TB incidence ≥300 per 100 000 had the highest prevalence (TST: pooled estimate 55%, 95% CI 41–69%; IGRA: pooled estimate 56%, 95% CI 39–73%). Annual incidence estimated from the TST was 1–38% (mean 17%); annual incidence estimated from the IGRA was 10–30% (mean 18%). The prevalence and incidence of a positive test was associated with years of work, work location, TB contact and job category. Only 15 studies reported on infection control measures in healthcare facilities, with limited implementation.HCWs in LMICs in high TB incidence settings remain at increased risk of acquiring LTBI. There is an urgent need for robust implementation of infection control measures.

Abstract Background Healthcare workers (HCW) are presumed to be at increased risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due to occupational exposure to infected patients. However, there has been little epidemiological research to assess these risks. Methods We conducted a prospective cohort study of HCW (n = 546) and non-healthcare workers (NHCW; n = 283) with no known prior SARS-CoV-2 infection who were recruited from a large U.S. university and two affiliated university hospitals. In this cross-sectional analysis of data collected at baseline, we examined SARS-CoV-2 infection status (as determined by presence of SARS-CoV-2 RNA in oropharyngeal swabs) by healthcare worker status and role. Results At baseline, 41 (5.0%) of the participants tested positive for SARS-CoV-2 infection, of whom 14 (34.2%) reported symptoms. The prevalence of SARS-CoV-2 infection was higher among HCW (7.3%) than in NHCW (0.4%), representing a 7.0% greater absolute risk (95% confidence interval for risk difference 4.7, 9.3%). The majority of infected HCW (62.5%) were nurses. Positive tests increased across the two weeks of cohort recruitment in line with rising confirmed cases in the hospitals and surrounding counties. Conclusions Overall, our results demonstrate that HCW had a higher prevalence of SARS-CoV-2 infection than NHCW. Continued follow-up of this cohort will enable us to monitor infection rates and examine risk factors for transmission.

Whether lockdown related to the COVID-19 pandemic influences alcohol consumption is not well known. This study assesses alcohol consumption and hazardous drinking behavior during the initial phase of pandemic measures in Norway and identifies potential risk factors. A cross-sectional study (N = 25,708) was conducted in Bergen, Norway, following the first six weeks of strict infection control measures. In a model of self-assessed increased alcohol consumption, logistic regression analysis was conducted with independent variables for COVID-19-related worries, joblessness, quarantine, self-reported drinking behavior, age, gender, and occupational situation. These are reported with odds ratios (ORs) with 95% confidence intervals. Fifty-one percent of respondents reported economic or health-related worries due to COVID-19, 16% had been in quarantine, 49% worked/studied from home, 54% reported hazardous drinking behavior, and 13% reported increased alcohol consumption. People aged 30–39 years had elevated odds of increased alcohol consumption during lockdown (OR 3.1, 2.4−3.8) compared to the oldest adults. Increased drinking was more frequent among people reporting economic worries (OR 1.6, 1.4−1.8), those quarantined (OR 1.2, 1.1−1.4), and those studying or working at home (OR 1.4, 1.3−1.6). More than half of respondents reported hazardous drinking behavior. Increased alcohol consumption during lockdown was common among people with economic worries, people in quarantine, and people studying or working at home. These data could be important when adjusting pandemic measures.
