Antibody response to the inactivated SARS-CoV-2 vaccine among healthcare workers, IndonesiaHealthcare workers (HCWs) are at risk for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due to increased occupational exposure to SARS-CoV-2 (Nguyen et al., 2020). As well as being beneficial for the HCWs themselves, protecting HCWs from SARS-CoV-2 infection is important to prevent disease transmission in healthcare and community settings (Anonymous, 2020). In addition, protecting HCWs from coronavirus disease 2019 (COVID-19) is crucial for the preservation and protection of national healthcare systems (Anonymous, 2020).
SARS-CoV-2 seroprevalence among 7950 healthcare workers in the Region of Southern DenmarkCoronavirus disease 2019 (COVID-19) surged as an ongoing worldwide pandemic throughout 2020 (Park et al., 2020; Siordia, 2020). The first Danish cases were reported in late February 2020, and the initial spread of infection most likely originated from ski tourists returning from Northern Italy and Austria (Madsen et al., 2021). The first epidemic wave in Denmark peaked in late March and early April, with 9.2 patients admitted to hospital per 100 000 population (Madsen et al., 2021; Statens Serum Institut 2021).
The role of supporting services in driving SARS-CoV-2 transmission within healthcare settings: A multicenter seroprevalence studyThe emergence of SARS-CoV-2 (causing COVID-19) in December 2019 rapidly evolved into a pandemic, with cumulative numbers of more than 83 million confirmed cases and 1.8 million deaths globally according to WHO (2021a). During the lengthy course of this pandemic, The Lancet (2020) reported that workers within healthcare facilities had been working at maximum capacity for many hours and over many shifts, and in some settings with limited protection. Being a frontline healthcare worker was found to be one of the risk factors for acquiring COVID-19, as shown in many serological studies, such as that by Galanis et al.
SARS-CoV-2 infection in mortuary and cemetery workersAs of 15 December 2020, more than 73 million people have been infected with SARS-CoV-2 and over 1.6 million deaths have been reported worldwide (Worldometer, 2021). Viral RNA can remain detectable for more than 100 days in 6.6% of patients after clinical recovery from initial infection; 5% their close contacts develop IgG antibodies, suggesting past exposure (Chirathaworn et al., 2020). Asymptomatic people are also well-documented transmitters of infection. Seropositivity for SARS-CoV-2 among healthcare workers varies between 3%–17% (Chen et al., 2020; Fusco et al., 2020).
The first wave of COVID-19 in hospital staff members of a tertiary care hospital in the greater Paris area: A surveillance and risk factors studyHealthcare workers (HCWs) are deemed to be at high risk of exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with a potential risk of transmission to vulnerable patients (Keeley et al., 2020; Galmiche et al., 2020). In Japan, Furuse et al. have shown that 30% of clusters identified in reported Coronavirus Disease 2019 (COVID-19) cases are linked to healthcare facilities (Furuse et al., 2020). Hospitals have initiated infection control measures to protect HCWs, ensure workforce availability, and decrease in-hospital transmission risk.
COVID-19 infection among healthcare workers in a national healthcare system: The Qatar experienceSince the identification of first case cluster in Wuhan, China, in December 2019, the COVID-19 pandemic has swept the entire world. The pandemic has overwhelmed hospital capacity and existing healthcare resources in many countries. Healthcare workers (HCWs) are a particularly high-risk group due to their close interactions with infected persons as well as lack or deficiency of personal protective equipment (PPE) in many settings. The rate of infection in HCWs is reported to vary between 3 and 17% and varies according to the history and degree of exposure and presence of symptoms (Lan et al., 2020; Fusco et al., 2020; El-Boghdadly et al., 2020; Chen et al., 2020).
