Question 1

I've been trying to understand the difference between the HIV RNA quantitative and qualitative tests. If I got a quantitative test done after six weeks, would it be a detection test, or is it more for measuring the amount of the virus if it's already detected? I'm a bit confused and would love some clarification.

Accepted Answer

If you're testing after 6 weeks of potential exposure and want to know the exact viral load or confirm HIV status, the quantitative test can still be useful, but a combination of tests (including antigenantibody tests) is often recommended for a more complete assessment. Always follow your healthcare providers advice on the timing and type of test.

Question 2

I recently got bitten by a street dog, which left a scratch without any bleeding. I quickly rinsed it with tap water for about 10 or 30 seconds and then got the intradermal antirabies vaccine around 45 minutes later. I'm a bit concerned about a few things. Could I still be at risk for rabies since I didn't wash the bite with soap for a full 15 minutes? Also, is there a chance my family could catch rabies just from washing dishes in the same spot where I cleaned my leg? I'm worried because I noticed the hospital might not have kept the vaccine cold the entire time I mean, they took it out in the morning and used it throughout the day, and I got my first dose around 4:30. For the second dose, they did get it right from storage, but the cool box was always open. Is there a possibility that this could affect how well the vaccine works and my chances of getting rabies?

Accepted Answer

For a scratch without bleeding from a street dog bite, washing the site with running tap water for 10-30 seconds is a good first aid measure. The risk of rabies transmission through such a scratch is very low. However, to be safe, you received the intradermal antirabies vaccine, which is the appropriate course of action to prevent rabies infection. Rabies is not transmitted through objects like utensils. The virus is primarily transmitted through the saliva of an infected animal, usually through a bite. Washing utensils where you washed the bitten site does not pose a risk of rabies transmission to your family members. The rabies vaccine is sensitive to temperature and must be stored properly to maintain its effectiveness. If the vaccine was not stored correctly, there is a risk that its potency may have been compromised. However, receiving the vaccine doses as you described (45 minutes after the bite and on the fourth day) is still beneficial in preventing rabies infection. It is important to complete the full course of the vaccine as prescribed by your healthcare provider to ensure protection against rabies.

Question 3

I'm feeling really stressed and confused about a recent potential HIV exposure. I had protected sex with a prostitute on December 26th, 2021, and today is January 17th, 2022. I've been reading a lot about symptoms online, and it's freaking me out. I took an HIV test (4th generation abag p24) on the 10th day after the exposure, and it came back non-reactive, with an index value of 0.12. Does this mean I'm in the clear, or do I need to take another test on the 28th day, like my doctor suggested? He mentioned that if I'm negative on the 28th day, I can just move on, but I'm still unsure. Can you help clarify this for me?

Accepted Answer

Stay calm, follow your doctors advice, and get the test done at 28 days. It's likely that you are HIV negative, but waiting for the additional test will help to definitively confirm it. Avoid reading too much online about symptoms, as it may only increase stress and anxiety.
