Answer 2

Answer:

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).

The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
