evidence: All individuals with COVID-19 need to wear a well-fitting, high-quality mask for a total of 10 days from symptom onset or their first positive test date (if asymptomatic) when around others; this applies to both indoor and outdoor settings. This includes individuals who test positive and have no symptoms or only mild symptoms. You can remove your mask sooner if you have two sequential negative tests at least one day apart. [...] As long as you do not feel sick, you do not need to stay home for a set number of days. However, there is a chance you could still pass the infection to other people, who may get sick and are at high risk for severe disease. This is why it is important to wear a well-fitting mask around others for 10 days after testing positive. You can still spread COVID-19 and other respiratory viruses, even if you have no symptoms. People with COVID-19 can be infectious 2 days before and up to 10 days after symptom onset or positive test date (if no symptoms). This has not changed, and that is why it remains important to wear a mask for 10 days after getting COVID-19.
