when is it ok to be around someone who has mono
If youâve been kissing them or sharing straws or drinks or eating utensils, go have your self checked for mono. They are contagious from the time they contract the virus themselves and may have not been symptomatic for 4 to 7 weeks. Mono has a long incubation period. Iâm sorry if this is bad news, but now you know. If you havenât been kissing or sharing spit, you should be pretty safe.
