I was working with dried blood spot samples in the lab with blood most likely hiv +. These blood spot cards were in bags and i used gloves. My concern is that i was touching my keyboard and phone with my gloved hands while handling the samples. After i was done with the samples i forgot to wipe off my keyboard and phone. I touched my face and possibly mouth or eyes after touching the keyboard and phone. I has symptoms after this and got blood tested about a month later for hiv,hcv,hbv and they were all negative.  This happened about 2 years ago and im still having anxiety about it. What is the risk of transmission from this exposure?

Hi there,

Thank you for your inquiry. From what we gather from the question, you are asking about the possibility of HIV transmission after coming in contact with dried blood samples that may or may not have been HIV positive. From the information given, this scenario is determined to be No Risk.

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 with 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 the samples did contain HIV positive fluid, the exposure to oxygen means there is No Risk of transmission from this activity.

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