Yesterday I cut my finger a bit as I passed a glass table in a bar. Apparently I did not see blood on the table, my wound bled a little not much, then I covered the wound with a napkin and put hydrogel of this that is now for COVID. Is there an HIV risk if there was blood on the table? On the other hand, when I left the premises I greeted a person with my hand, would there be a risk if this person were HIV? It may sound silly but I need an answer if there was any real risk in what I said or are they paranoia of mine. Thanks 0CB3F2BC-BB2F-4037-A82C-193E1A027920.png

Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission given that you cut your finger on a glass table that may have had HIV positive fluid on it. Based on the information provided, this scenario is determined to be of No Risk (transmission of HIV is not possible in the given scenario).

In order for transmission to occur, a number of requirements must be met (see below).

HIV transmission requires the presence of HIV positive fluid (such as semen, vaginal fluid, pre-cum, rectal fluid, breastmilk, etc), coupled with a High, Low, or Negligible Risk activity, that provides the virus direct access to the bloodstream. 

The activity you described above is of No Risk because "HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host" (1). Due to exposure to oxygen,  HIV undergoes a rapid reduction in concentration. Therefore, in the event that there was dried blood on the table, the virus would be rendered inactive following exposure to oxygen, meaning there is No Risk of transmission from this activity.

To answer your second question, HIV cannot be transmitted through shaking hands, hugging, sharing utensils, etc. as there is no exchange of bodily fluids. 

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