SARS Wars: the Fomites Strike Back

Controversy continues about the significance of fomite transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Recent papers continue to advocate concern. However, designs of studies showing virus survival on surfaces under laboratory conditions are unsuitable for extrapolation to real life. Although viral RNA is frequently found on real-life surfaces, actual tests for infectious virus are almost entirely negative, even in hospitals with COVID-19 patients. Fomite transmission should be regarded as no more than a very minor component of this pandemic.

Debate continues about the significance of fomite transmission of SARS-CoV-2, with studies showing virus survival on surfaces not necessarily reflecting real-life conditions. Despite frequent presence of viral RNA on surfaces, tests for infectious virus are largely negative, even in hospitals with COVID-19 patients. Fomite transmission is likely a very minor component of the pandemic.
