I'm a 21-year-old guy and had unprotected oral sex with a girl, but I don't know her HIV status. I also ejaculated in her mouth. I've taken the HIV Tridot test three times once after 30 days, then after 45 days, and again after 74 days. All the results were negative. How reliable are these tests, and could they turn positive later on? What's the window period for the HIV Tridot test? I'm pretty anxious about this and would like to understand more.

The HIV Tridot test is highly accurate after 74 days, as the window period for most HIV tests is 2-12 weeks. Since your results are consistently negative, the chance of turning positive later is extremely low. For complete peace of mind, a confirmatory test at 90 days (like a 4th-generation test) is advisable.

I'm really concerned about my HIV status. So, I had a PCR RNA test 22 days after potential exposure, and it came back not detected. Then, at 44 days, I did an HIV combo test and it was negative. Finally, I did HIV rapid testing at 76 days, and that was negative too. Based on these results, am I in the clear?

I've had all three of my rabies shots right on time, but I've missed the fourth one that was supposed to be on the 15th. It's now the 16th. Is it okay to get it on the 17th, or should I be worried?

Antibiotics are ineffective against viral infections. Continue taking Dolo 650 to manage fever and symptoms. Consider adding: 1. Rest and hydration 2. Warm liquids (e.g., tea, soup) 3. Saline nasal drops (for congestion) 4. Cough syrup (if needed)
