Can you spread the virus if you don’t have symptoms?

Yes. Most people who are infected with COVID-19 will develop symptoms within 2-11 days, with an average of 5 days. Similar to some other respiratory viruses, individuals will shed virus prior to developing symptoms. Estimates of how long this pre-symptomatic period vary and have been suspected to be up to 2 days. In addition, some individuals will be entirely asymptomatic when infected with SARS-CoV-2. Therefore, someone who does not show symptoms may already infected with the virus and be able to transmit the virus.
