Initially healthcare providers recommended a 14 day quarantine, some even suggested this timeframe may not be long enough. Currently, in January 2021, medical providers are recommending a 10 day quarantine after the peak of symptoms or 14 days from the known date of exposure.
Someone can carry the virus longer based on the severity of their symptoms, which is why as of January 2021 they recommend a 10 day quarantine from the peak of symptoms. The chart shows that you can carry the virus longer with more symptoms, but the recommended timeline is outdated.
Updated research shows that if you come in contact with the virus, and remain asymptomatic (no symptoms), you will be contagious for approximately 10 days. Another individual who develops breathing problems, nausea, vomiting, diarrhea, or other various symptoms can be contagious for a longer period of time, but it is still uncertain the exact amount of time. Healthcare providers are currently recommending a 10 day quarantine after the peak of symptoms, January 2021.
The peak of symptoms is when your symptoms are the worst. When did you feel the worst? When did you have a fever, cough, or whatever other severe COVID symptoms? Go 10 days out from that day and you should prevent transmission to others.
