Contrary to expectations, hospital cleaners are at a higher risk of getting the Covid-19 infection, compared to intensive care unit (ICU) clinicians, according to a study published in the journal Thorax.

The researchers suggest that the type of personal protective equipment (PPE) worn may be key to these differences, which are likely to be relevant for any second surge in Covid-19 this winter.

"We presumed intensive care workers would be at highest risk... But workers in ICU are relatively well protected compared with other areas," said study author.

For the findings, the research team offered to test staff with no Covid-19 symptoms for both current (throat and nose swabs to detect antigen) and previous (blood test to detect antibodies) infection.

545 asymptomatic healthcare workers were recruited while at work and were asked to report any illnesses consistent with Covid-19 that they had had in the previous four months.

Nearly 2.5 per cent staff with no symptoms tested positive for SARS-CoV-2. Of these, 38 per cent subsequently developed Covid-19 symptoms.

The findings showed that cleaners had the highest antibody positivity (seroprevalence)-- 34 per cent followed by clinicians working in acute medicine (33 per cent or general internal medicine 30 per cent.

The lowest seroprevalence was found among staff working in intensive care medicine 15 per cent, emergency medicine 13 per cent, and general surgery 13 per cent.

"This is an observational study, and not all participants provided all the information requested. Nor is it known whether symptomless infection among staff puts hospital patients at risk," the study authors wrote.
