Can someone spread the virus without being sick?

It's possible for people to spread the virus for about two days before experiencing signs or symptoms and many remain contagious for at least 5-10 days after signs or symptoms first appeared. If someone is asymptomatic or their symptoms go away, it's possible to remain contagious for at least 5-10 days after testing positive for COVID-19. This is why it is important to wear a well-fitting mask around others for the full 10 days after your symptoms start or if you don't have symptoms, for 10 days after your positive test. Day 0 is the day you start having symptoms, or if you don't have symptoms, the day of your positive test.
