Viruses are constantly changing, which sometimes leads to new strains called “variants.” Different COVID-19 variants can have different incubation periods.

But if you do catch it after you’re vaccinated, the vaccine will still protect you from getting as seriously ill or needing h...
The CDC says that if you might have come into contact with the virus and have no symptoms, you should self-monitor. This means watching for signs such as fever, cough, and shortness of breath. Stay out of crowded places, keep at least 6 feet away from other people, and wear a high-quality face mask when you have to go out. If you know that you came...
