2. Am I still infectious after recovering?
Probably to some extent, though the first batch of studies is far from conclusive as to how long it lasts.
Provisional research from Germany has suggested that COVID-19 infectiousness – in contrast to the 2003 SARS outbreak – peaks early and that recovering patients with mild symptoms become low-risk around 10 days after they first fall ill. But
another study, following four medical professionals treated at a Wuhan hospital, revealed that traces of the virus could persist in the body for up to two weeks after symptoms had vanished; as the patients were no longer coughing or sneezing, the potential means of transmission were albeit much reduced. Less optimistic was a study published last week in
The Lancet medical journal that showed
the virus survived in one Chinese patient’s respiratory tract for 37 days – well above the average of 24 days for those with critical disease status.
