Hello doctors, I am a male and i have 2 scenarios that took place within this year and i would like your advice.1.

In Dec 2021 i met a csw and we engaged in sex. During sex the condom broke twice. I did a duo test 33days post exposure and the result was negative. As per my doctor here in DXB he said it was conclusive. However 3days after the 4th gen test, I tested positive for covid as my whole family was infected. somewhere between 40-45 post exposure and after my 4th gen test i developed a swollen lymph in the right side my underchin. The 2nd, 25 days ago i went to massage parlour where the masseuse performed 10-15sec unprotected oral on me however i told her to use condom after this and she did. She also rubbed her body against me including her genital area against my body. there was a portion of the rubbing when my penis was unprotected. There was no penetrative sex. I have had an itch for the last week or so in my upper back and neck area.

The way things have progressed in my life over the past year like meeting family who i had not met for a long time and so on has made me very anxious and nervous regarding HIV. I have tried to remain calm after my negative result in the beginning of the year however sadly its always been bugging me in the back of my head for the last 8 months. To add to the anxiety My visa renewal is coming up and they test for HIV which furthered the anxiety.

1. Could the 4th gen result have been false negative given that i probably had covid during the test?

2. I do plan on getting tested again next week to rule both events, given the circumstances, what are the chances that my result can return positive?

1,  4th generation HIV tests detect more than 99% of recent infections at 28 days following an exposure, even a higher proportion at 33 days.  4th generation tests are considered absolutely conclusive at 6 weeks.  Neither of us has ever seen or heard of a person who have an HIV test convert from negative to positive after 28 days.  There are no data to suggest that COVID is in any way associated with falsely negative HIV tests.  

Receipt of oral sex has never been proven to lead to HIV.

2,  Your chances that the tests next week will be positive are virtually zero.

Hope this information is helpful.  EWH
