I just got a covid booster shot a week before Sept 6.
Those of us who are immunosuppressed can harbor the virus an especially long time, Gay. Do you still have symptoms? The tricky thing is that it may be nonviable (dead) virus that we're still shedding. There's no way to know for sure, so I'm sure you're masking in the meantime.
I will thanks
I hope you get better soon. You may want to call your primary care doctor and speak about testing positive, for such a long time.
