Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV by touching door knob while have a small cut on finger. From the information given, this scenario is determined to be No Risk transmission of HIV is not possible with the given scenario. (No exchange of bodily fluids)

In order to contract HIV the following conditions must be met: There must be HIV present in a bodily fluid. The five bodily fluids that carry the HIV virus include: blood, semen (including pre-ejaculate), vaginal fluids, breast milk, and rectal secretions. The bodily fluid containing HIV must have direct access to the bloodstream. This can be through cuts, tears, rips, mucous membranes, open sores, or needles. Transmission occurs through a risky activity in which the first two conditions are met. For example: condom less sex, sharing needles, unsafe tattoos or piercings, vertical transmission–from mother to child (in utero, during delivery, breastfeeding).

There is no risk of acquiring HIV in the above mentioned scenario. Assuming that the door knob had some blood, it must gain direct access to the bloodstream via open/large cuts or sores that are visibly bleeding. Also, HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host. HIV outside of the body or drying HIV causes a rapid 90%-99% concentration depletion (within several hours). Quote from CDC states: "HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host.

The symptoms you are experiencing can be due to other causes or illness. Because HIV symptoms mirror other viral infection or can be due or explained by other things, testing is really the only way to know.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
