I was exposed to covid 5 days ago. i don't have any symptoms & unable to get tested due availability issues. what are the chances that i have it after 5 days of no symptoms?

If you are vaccinated, you need not be concerned about getting sick. Incubation period is up to 14 days and even if you are vaccinated you could spread it even without symptoms. Try to isolate yourself, wear a mask around other people. Get vaccinated, if you are vaccinated, get a booster dose.

Exposure doesn't mean you contracted the virus .If you are unvaccinated or vaccinated you still may be positive or even negative depending on the amount of antibodies in your body. It takes about two weeks for symptoms to occur and now the govt. is adding more testing sites so look for the new ones and get tested.
