Is it possible for me to develop a cold from a virus i was exposed to before qnd fought off and/or been gone latent in my body without being exposed to other sick people? How long can cold viruses be latent in the body with the ability to reactivate? Submitted by sewcrazy4cats t3_10ljt5v on January 26, 2023 at 4:50 AM in askscience 11 comments 46
