Question 2

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?

Accepted Answer

Advised elisa hiv test at 6 months and at 1 year.

Question 3

I'm getting a bit worried because a couple of months back, a street dog tried to bite me but didn't really get a good grip. It left a small wound on my thigh just with one of its teeth, and I cleaned it up with Dettol right afterward. It's been over two months now, and its almost healed  there's just a little dark spot left. Everything seemed fine, but now Im starting to get anxious about whether I could've picked up any infections or viruses from it. I see the same dog around regularly, so I can identify it if that helps. What should I do to check if Im all clear from any infections or viruses from the encounter?

Fever Persisting Despite Treatment

_Test results interpretation:_

1. _Initial tests (2132016)_:
    - Typhoid rapid test: Positive (IgM antibodies), indicating recent typhoid infection.
    - Negative results for malaria and microfilariae.
2. _Follow-up tests (2552016)_:
    - Typhoid rapid test: Negative (IgM and IgG antibodies), suggesting the infection has been cleared.

_Persisting fever:_

1. _Possible causes_:
    - Relapse or re-infection with typhoid
    - Other underlying infections (e.g., urinary tract infection, pneumonia)
    - Inflammatory or autoimmune conditions
    - Medication side effects
2. _Additional tests recommended_:
    - Blood cultures to rule out ongoing bacterial infections
    - Complete Blood Count (CBC) to assess for signs of infection or inflammation
    - Erythrocyte Sedimentation Rate (ESR) or C-Reactive Protein (CRP) to evaluate for inflammatory conditions
    - Urine analysis and culture to rule out urinary tract infections
3. _Fever type:_
    - The persistent fever could be a low-grade fever, which is a common symptom of various conditions.

I'm really concerned about how long it usually takes for someone to test negative after being positive for COVID. Can you provide some guidance on this?
