Thank you very much for responding to my enquiry, my case is that on the 19th of October I had intercourse with a sex worker and the condom broke. A few days later I had runny nose that lasted about 3 weeks, then end of those 3 weeks I had sore throat where I had to clear my throat most of the time as there is much mucous ( I m still having the sore throat ), its white in color, I also noticed 3 swollen lymph nodes on my neck. I was worried, I took a 4th generation hiv rapid test on 14th of October and it turned out negative, I also took a another 4th generation hiv rapid test on 23 of October and it was negative. Moreover I did a blood test, the result came out normal according to my doctor....but I m still worried as the sore throat is still present and I ve never had a sore throat that lasted this long, is there a possibility that 4th generation test would fail to detect hiv at the 4 - 5th week?
