Hello and thank you for posting your medical question on E health Forum. I am glad I can help you here.
From the available history, it seems that you are anxious regarding the exposure due to the tear of the condom. It is understandable. The constellation of symptoms described here after the exposure are not due to HIV. They could be due to unrelated but incidental skin infections and upper respiratory tract infections. If they are persisting and the symptoms are severe, you may need a short course of antibiotics for a few days.
Use of a latex condom during sex can reduce the risk of HIV infection because it reduces the chance of getting semen, blood and vaginal secretions (fluids known to carry the virus) into the body. Since condoms can break or slip, people should not rely on them as their only defense against HIV. Additional protection can be provided by using a spermicide, such as nonoxynol-9, with a condom.
The HIV ELISA antibody test detects antibodies for HIV and is very reliable with a sensitivity of 99.7% sensitive and specificity of 99.9%. It give a positive result within 4 -12 weeks of exposure. In your case since the test was done at 6 weeks post exposure, a negative test is conclusive to indicate that you are HIV NEGATIVE. There is no need to have any more doubts in this regard.
You may consider to consult your physician for reassurance and counselling as well as to treat your co-existing skin and upper respiratory infections.
I hope you find this helpful.
