I walked next to my friend outside on tuesday. on wednesday, she tested positive for covid. when i was around her inside, i had on a kn95 mask, but im a bit worried about my exposure outside still. what is the risk i caught covid from her outside?

If you were close together - then there are chances you were exposed. Getting the infection depends on the kind of exposure, your immune system, whether you were immunized and the type of covid virus she has. So see not easy to predict. good luck

If you were vaccinated and boosted multiple times, there is still the chance of exposure. The virus if contracted should be a mild form depending on your immune system and the variant. If symptoms arise do a home Covid test.
