So I recently visited one of my hiv positive friends and she prepared some food for me to eat. Let's say that she dropped blood on my food and I ate it after just one minute, am i at risk?
i do have a few sores in my mouth but nothing like constant bleeding or sti (do these small sores put me at risk?)
also, once outside the human body, how long does it take for the hiv virus to die?
Hello and thank you for contacting the AIDS Vancouver Helpline.

We are happy to help answer your questions, and want to let you know that there is no risk associated with this exposure. We are glad that your friend's status isn't stopping you from spending time together, even though you may be worried these situations sometimes. We have included a [great resource](, as well as our [Risk Chart]( to help reassure you that *HIV cannot be passed through casual contact* we engage in every day. Here's why:

For a risk of HIV transmission to exist, 3/3 parts must be present in an exposure:


---------- -------- ----------------------------
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection

In your exposure...

* Body fluids (e.g. blood) present are exposed to the air, AND exposed to saliva which reduces the risk of transmission happening. When the virus is outside of the human body, it becomes damaged very quickly and cannot enter another human body again. The virus also needs a human body to reproduce itself, and cannot be passed on when coming into contact with body fluids (that are outside of the body).

* There is no exchange of body fluids. The blood you may have come into contact with was exposed to the air and to saliva and cannot pass on HIV. Your sores are not considered a risk factors since, the blood was outside of the human body *before* you came into contact with it.

* There is no high-risk activity involved in your exposure. Eating food prepared by a person living with HIV, sharing food with a person who is living with HIV, etc carry no risk for transmission.

Additionally, we want to let you know that many people today who are living with HIV take medication that helps them manage the condition and enjoy a healthy life. Many people who use their medication consistently are even able to reduce the risk of transmission during high risk activities, so you may rest assured that engaging with your friend casually during everyday activities really does not carry any risk for acquiring HIV.

We trust we have answered your questions, and have included this reliable [resource]( to support our answers (*see: how well does HIV survive outside the body?).
