It has been 45 days since I doubt I have been infected with hiv. I got an hiv 1 and hiv 2 antibodies screening test on 46th day which came out to be negative. But I experience nasal congestion, fever and sore throat for 3 days last week, but since then I am experiencing dry cough with visible bumps on throat wall. Should I be worried of hiv? Is the antibodies test accurate after 46 days of being infected?
