Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about your risk of acquiring HIV when using utensils (chopsticks, straws, etc.) that many contain blood while you have scratches in your mouth and on your lips. 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 Transmission Equation(1). It does not satisfy the equation because:

  • HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host(2).

  • All 3 components of the HIV Transmission equation must be met for transmission to occur. There must be a bodily fluid containing HIV (ex: blood, breast milk, rectal or vaginal secretions), direct access to the bloodstream (ex:inside of the vagina or anus, mucosal membranes), both paired with a high risk activity (ex: unprotected vaginal or anal intercourse, sharing needles, or mother-to-child)

For your scenario this means that there is No Risk of HIV transmission. Why? We know from above that HIV does not survive long outside the human body (such as chopsticks, bowls, etc), and it cannot reproduce outside a human host. This means that any bodily fluids (blood) on a bowl, straw, or chopsticks is outside of the human host, has been exposed to environmental conditions and thus, cannot reproduce. There was also no direct access for bodily fluids containing HIV to enter your bloodstream. The scratches in your mouth and on your lips made by eating would be considered superficial cuts. Superficial cuts can be likened to that of a paper cut. They are shallow and simply do not provide a deep enough access point for bodily fluids containing HIV to enter your bloodstream.

We would encourage you to check out some great resources we've listed below to learn more about HIV transmission.

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