My partner is experiencing high temps with the possibility of it being covid related as a mutual friend tested positive who we were in contact with 7 days ago. how likely is it that i have covid too? i'm currently showing no symptoms?

Likely: Many people in your age group if in good health won’t show any symptoms but you still may be able to spread to there. Quarantine and get tested so you can know when safe to exit quarantine. Get plenty of rest and liquids and no smoking and minimal alcohol and supplements if necessary based on your diet.

Likely covid: If you have no symptoms I feel you should isolate at least 10 days,( preferably 14,) even if you test negative, from when your partner became ill. If you develop symptoms isolate 14 days as well as 3 days with no symptoms. It's important to realize that your apartment or home is contaminated with the virus and you could spread it to others even without having symptoms.
