Most adults with severe to critical illness or severe immune suppression likely remain infectious for up to 20 days after symptom onset.
In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
What are some potential long term effects of COVID-19?
