If I am not feeling sick, can I have coronavirus and still be contagious?


It’s important people realize they can be infected with the SARS-CoV-2 virus for up to 2 weeks before they feel sick. During that time they could spread the infection to others by shedding the virus as they talk, laugh and touch items in their daily life. This knowledge is based on data from China in early 2020. An analysis of 181 adults showed that after being exposed to the virus, half got sick within 5-6 days and the majority were sick within 14 days.

Social distancing is critical. Data from China and cruise ships estimate a person infected with the virus that causes COVID-19 can infect 2-3 people, who then can infect another 2-3 people. This exponential growth could lead one person with the infection to grow to over 4000 people with the infection in a month if measures like social distancing, quarantine and isolation don't happen.
