SINGAPORE – After 11 days of getting sick, Covid-19 patients no longer pose a risk of spreading the disease – which means they can be safely discharged.
Singapore now discharges patients only after two swab tests are negative for the virus. But a local study has shown that while the patients might test positive, it “does not equate to infectiousness or viable virus”.
That’s because the test detects parts of the virus’ genome, but is unable to show if they are just fragments of the virus, or if an intact virus is no longer viable and can’t infect anyone.
The position paper from Singapore’s infectious diseases experts say these new findings allow for revised discharge criteria.
