I'm feeling really anxious because a while back, I had a risky encounter with someone whose HIV status I don't know. It's been 180 days since then, and I did an HIV test on day 179. The test I took was the HIV 1 and 2 p24 CMIA, and the result came back negative with an index value of 0.09. I'm trying to understand more about the window period for HIV testing and whether the CMIA test is as reliable as the ELISA test. Also, does taking the test two days earlier, like on day 179, affect the accuracy at all? I had multiple tests throughout this periodone at three months with an index of 0.07 and another at day 42, which was also negative with the same index value. Can you help me make sense of all this?

I'm really worried because this morning I accidentally drank some water from a can that had a dead rat in it. Can anyone advise me on what I should do now? I'm pretty scared about it, please help!

Immediately rinse your mouth and throat with clean water, then drink plenty of safe water to help flush out your system; monitor yourself for symptoms like fever, vomiting, diarrhea, or abdominal pain, which can indicate leptospirosis or other waterborne illnesses;

I've been feeling really off for the past two weeks. My thermometer readings are normal, but Im still experiencing feverish chills and shivers. I did some blood tests like complete blood count, C-reactive protein, and malaria, but everything came back normal. I also had the typhi dot IgM test, and it showed a weak positive. Can you help me understand what a weak positive means in this context? I'm attaching my report for reference.
