I was sharing with a friend an electronic cigarette.
My friend had dry lips which were slightly bleeding.
His lips' blood contatced and passed to the edge of the Electronic cigarette
(The edge of E-Cigarette where you put the lips and inhale from the electronic cigarette).
We passed the electronic cigarette from each other a few times.
Each of us took few inhalations from E-Cigarette and than passed the E-Cigarette to the other.

After a while from the massive usage of the elecronic cigarette,
the electronic cigarette became very hot in the edge.

In my last inhalation from the hot electronic cigarette I got thermal burns on my lips
and on my fingers from the hot electronic cigarette edge.

If the thermal burns on my lips and fingers came in contact with the blood of my friend on the edge of the electronic cigarette,
what is the HIV risk from this contact of the burned lips and fingers with blood on the edge of E-Cigarette?


Does the thermal burns on my lips and my fingers increase HIV risk
when coming in contact with the blood of my friend on the edge of the electronic cigarette?

Thank you for the help.

Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through contact with blood on the edge of E-Cigarette with your burned lips and fingers.  From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).

The scenario mentioned above does not meet the three components of the HIV Transmission Equation (see down below).

Even if there had been fluid containing any active HIV particles on the E-Cigarette, exposure of the virus to oxygen quickly deactivates it. The CDC has shown that "HIV does not survive long outside the body (such on surfaces), and it cannot reproduce outside of the human host" (1). When HIV is exposed to oxygen, it undergoes a rapid decrease in concentration (90-99% within a couple of hours), so the risk of environmental transmission of HIV is essentially zero (1). Therefore, in the event that the E-Cigarette used did come in contact with HIV positive bodily fluid, the exposure to oxygen, coupled with the fact that there was no direct access to your bloodstream, means there is No Risk of transmission from this activity.

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

Regards,
