Differential occupational risks to healthcare workers from SARS-CoV-2 observed during a prospective observational study

Abstract: We conducted voluntary Covid-19 testing programmes for symptomatic and asymptomatic staff at a UK teaching hospital using naso-/oro-pharyngeal PCR testing and immunoassays for IgG antibodies. 1128/10,034(11.2%) staff had evidence of Covid-19 at some time. Using questionnaire data provided on potential risk-factors, staff with a confirmed household contact were at greatest risk (adjusted odds ratio [aOR] 4.82 [95%CI 3.45-6.72]). Higher rates of Covid-19 were seen in staff working in Covid-19-facing areas (22.6%… Show more

“…This can be explained by the lack of protection and information in the most unprotected social strata, and in this we agree with Hawkins et al [ 21 ]. Curiously, healthcare workers showed much smaller frequencies than those reported by other authors as Eyre et al [ 22 ], although as we previously said, the sample is not large enough to draw conclusions in this regard. In our opinion, cutaneous manifestations of COVID-19 can be significantly polymorphic, occasionally non-specific, and ultimately resolve spontaneously.…”

“…Asymptomatic health care workers were invited to participate in voluntary nasal and oropharyngeal swab PCR testing every 2 weeks and serologic testing every 2 months (with some participating more frequently for related studies) beginning on April 23, 2020, as previously described. 5 , 22 Staff were followed until November 30, 2020. Deidentified data were obtained from the Infections in Oxfordshire Research Database, which has generic research ethics committee, Health Research Authority, and Confidentiality Advisory Group approvals.…”

“…The 60-day window was prespecified to exclude persistence of PCR-positive RNA after the index infection that led to seroconversion, on the basis of earlier reports of RNA persistence for 6 weeks or more. 22 , 25 , 26 Similarly, we considered only PCR-positive tests occurring at least 60 days after the previous PCR-positive test.…”

“…38 The adequate and correct use of PPE is the best measure to prevent HCWs from acquiring COVID-19 infection. 39 However, at the early stage of the outbreak, a global shortage of PPE occurred, and HCWs lacked practice on the proper donning and doffing of PPE. 40 Insufficient knowledge and skills related to the isolation of respiratory diseases pose a high risk of infection with HCWs.…”
