The discovery by a team of researchers from Vanderbilt University Medical Centre, that almost half the healthcare workers tested for Covid-19, tested positive but displayed no symptoms is evidence, if any more were needed, of the importance of wearing a face-mask in all public places.
Among 249 front-line health care workers who cared for COVID-19 patients during the first month of the pandemic in Tennessee, 8% tested positive for COVID-19 antibodies by serology testing, suggesting they had contracted COVID-19 in the first several weeks of taking care of COVID-19 patients. Among these health care workers with positive serology results, 42% reported no symptoms of a respiratory illness in the prior two months. This suggests that front-line health care workers are at high risk for COVID-19 and that many health care workers with the virus may not have typical symptoms of a respiratory infection. These results were published in the journal Clinical Infectious Diseases on July 6.
