Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission in the event that scratches on your neck had come into contact with vaginal fluid which was transferred there by hand. Later, you mention that you received HIV screening 34 days after the event, with concerns about HIV related symptoms you were experiencing.
From the information given, this scenario is determined to be of No Risk (transmission of HIV is not possible in the given scenario). The scenario described above does not meet the requirements of our HIV Transmission Equation. The requirements are not met because, although there is the presence of bodily fluids, there is no High, Low, or Negligible Risk activity, and thus, there is no direct access to the bloodstream. Although you had described there to be cuts on the back of your neck, this does not provide a direct access to the bloodstream. Superficial cuts and scratches are not deep enough to provide an avenue for HIV transmission. Further, the fluid that you describe has been exposed to oxygen, providing another barrier to transmission in this case.
Consider this quote from the CDC: "HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host" (1). Additionally, this means that HIV positive fluids that are exposed to environmental surfaces, such as hands, undergo a rapid reduction in concentration and are quickly rendered inactive.
Although symptoms may indeed indicate an acute phase of HIV transmission, it is not possible to confirm diagnosis without adequate testing confirmation.
In regard to the testing you received; we are unable to determine from your question which testing method you had received. However, most testing methods are considered to provide completely conclusive results 3 months (12 weeks) post-exposure.
In your case, we would not have originally recommended HIV testing for the scenario provided. It is incredibly important to know one's status in order to protect yourself or others from HIV acquisition, which makes your decision to seek testing admirable.
Due to restrictions in our understanding, we would officially Recommend re-testing after 12 weeks for completely conclusive results. Although you may consider the results you have already received to be extremely reliable.
All the best,
AIDS Vancouver Online/Helpline, Cody
