How long do you need to self isolate if you test #COVID19 positive? It depend:
📌symptomatic: 10 days from symptom onset & extra 3 days w/o symptoms.
📌asymptomatic: 10 days from date of PCR (+)test
➡️ And if we had cheap antigen home testing, we’d have even faster isolation.

2) How do we know this? From this study. “SARS-CoV-2 appears to be most contagious around the time of symptom onset and infectivity rapidly decreases thereafter to near-zero after about 10 days in mild-moderately ill patients” academic.oup.com/cid/advance-ar…
3) However authors point out, “and 15 days in severely-critically ill and immunocompromised patients”.
4) “The longest interval associated with replication-competent virus thus far is 20 days from symptom onset”
5) For example, for a patient with symptoms for 14 days, the patient can be discharged (14 days + 3 days =) 17 days after date of symptom onset; for a patient with symptoms for 30 days, the patient can be discharged (30+3=) 33 days after symptom onset). who.int/news-room/comm…
