Question

I took an HIV 1 and 2 antibodies screening and an HIV 1 and 2 p24 combo test 86 days after I was exposed. The results came back negative. Can I be sure that's conclusive at this point?

A negative HIV 1&2 antibodies and p24 combo test after 86 days (approximately 3 months) of exposure is highly suggestive of non-infection, but not conclusive. Here's why: Reasons for Caution 1. Window period: HIV antibodies may take up to 3-4 months to develop. 2. False negatives: Rare, but possible due to laboratory errors or test sensitivity. 3. Viral load: Low viral load may not trigger antibody production. Next Steps 1. Repeat testing: Schedule another HIV test 3-6 months after initial exposure.

Question

I'm really worried about the test results. The Widal test came back positive with Typhi O at 140, Typhi H at 180, and both Typhi AH and BH at 120. I'm not sure if this points to typhoid or malaria. Could you help me understand what these results mean?

Question

I'm really worried because I got bitten by a bat about a month ago and I didn't get the rabies vaccine. Do bats carry rabies? Should I be concerned?

Question

I'm super worried and need some clarity. So back in 2001-2002, I got bitten by a dog but didnt get any vaccines then. Jumping ahead 5-6 years later, I started getting anxious about it and took 3 rabies vaccines in 2008. Since then, Ive had a total of 12 rabies vaccines between 2008 and 2012, taking them post-exposure. Does that mean I'm still at risk of rabies in the future because I took the vaccines late? Also, last year I went to a mela and had dinner at a hotel where the food was kept on the floor in a container. Later, I started stressing out about whether a dog might have eaten that food too. I've heard rabies has an incubation period of 1-3 months. Im past 67 months now, so is there still a risk? Some people suggest getting tests like the Nuchal biopsy Rabies Antibody test. This is all overwhelming, and I could really use some advice.
