Evidently you still need to quarantine. Here is from the Centers for Disease Control:
"You can be around others after:
- 10 days since symptoms first appeared,
- 24 hours with no fever without the use of fever-reducing medications,
- other symptoms of COVID-19 are improving*
*Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation
It doesn't show here, but in the CDC website, the "and"s are in bold, meaning, all parts of the description must be there before you can come out of quarantine.
Are you under a doctor's care? I would consult my doctor about the fact you still have a daily fever. Your doctor should also be able to tell you when you have recovered to the point you no longer need to quarantine, or at least give an educated guess, assuming your doctor is experienced at treating covid.
I had a fever for 12 straight days with covid. Not fun. Then I had congestion a few days longer. My doctor told me what Anniebrooke says . . . I was told I needed to count the days of symptom onset and needed to be 10 days out at least from first onset of symptoms and 24 hours out from last day of fever. So, once your fever subsides, wait 24 hours. CDC is really clear on this information in terms of how long are you contagious. I also think that after having covid, would guess some secondary infections should be watched out for. Covid can linger. I was surprised I had a fever day after day for so long. Drink lots of water and get plenty of rest.
I was just reading in the Atlantic magazine about success in Bhutan at fighting Covid (they have only had one Covid death). The article said one thing Bhutan did from the beginning that was different than elsewhere was require that quarantine should be 21 days. It says, " A 14-day quarantine leaves about an 11 percent chance that, after being released, a person could still be incubating the infection and eventually become contagious."
