Would HIV transmit from Shaving Blades

Question: 

Hello,

I left my shaving blades in the bathroom for 3 days, and I used it in the morning. I checked my shaving blade before I use it, and it was dry. I rinsed it with hot water for about 1 minute. My question is If my roommates who were HIV positive had used my shaving blades without telling me, would I get HIV from using it? Thank you for your time.

Answer: 

Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of HIV transmission from your razor blade which may or may not have been used by your roommates (who are of unknown HIV status).

From the information given, this scenario is determined to be of No Risk (transmission of HIV is not possible in the given scenario).

This scenario is determined to be of No Risk because HIV exposed to oxygen or in the environment undergoes a rapid reduction in concentration, and is quickly rendered inactive. For this reason, HIV positive fluid does not survive long outside of the human host and therefore does not pose a risk for transmission (1).

Dry blood or any residual blood that may have been left on the razor would undergo this same process. The environment breaks down the HIV that the blood may contain. For this reason, razor's that have been previously used do not pose a risk for HIV transmission.

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

All the best,
