ARS cannot be "cured" by taking any medication. The symptoms can be treated, and will be eased slightly, but the syndrome itself will not abate until it runs its course. Example, you could take Tylenol for the high fever associated with ARS, and the Tylenol would reduce the fever slightly, but then it would go back up again.
Also can seroconversion start 5 days after the possilble exposure??? When they are present (which isn't consistent), ARS symptoms can present themselves at about 2-4 weeks post exposure, with the symptoms lasting 1-2 weeks.
Is runny nose,blocked nose symtoms of ARS??? No. Sounds like a cold.
Symptoms are a horrible way to gauge HIV risk and status. The symptoms are inconsistent and highly variable. If you have had an HIV risk, the only way to know your status is to test.
