ED123

I stopped at a car accident last week and there was a gentleman who was bleeding slightly from nose and on his hand.  I didn’t touch any of the wounds but I lifted his jacket and his bags.  I got home 20 mins later and started biting my nails and tasted blood.  There was no visible blood on me and I had been blowing my nose so could have been my own. I am panicking now that it may have been the gentleman’s blood on my finger and if it was could it infect me if he is infected? 


thank you x

Hi there,

Thank you for your inquiry. From what we gather from your question, you are asking about the possibility of HIV transmission after potentially coming in contact with blood and then biting your nails. From the information given, this scenario is determined to be No Risk (Transmission of HIV is not possible in the given scenario).

For HIV transmission to be possible, three components must be met (see below).

Helpline Transmission Equation .jpg 

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 your fingernails, the virus would be rendered inactive following exposure to oxygen, meaning there is No Risk of transmission from this activity.

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