Arne thanks for your great answer. One follow up is in the paragraph where you said that even if blood got into your mouth the saliva enzymes etc would kill it etc.........what if the mouth had small micro cuts etc?

Question:
Hi I read some of your recent answers and I too had an experience below.

If someone who is actively bleeding, dripped/put blood from a finger, and dripped/put blood into an EMPTY water bottle, and quickly capped it, would the HIV survive in the empty water bottle? I ask this worrying that the capped water plastic bottle would be considered airtight or is that different than airtight like a needle?

Then, if the bottle is re-opened 30 seconds later and quickly, filled with water, then drank, would the HIV virus be alive due to being in empty CAPPED water bottle, and thus a risk to the person drinking the contaminated water with blood? Would the water kill it when poured into bottle? Or would the air have already killed it in 30 seconds before even the water was poured in? Is a capped water bottle considered airtight?

Please very nervous teenager and please be detailed and do I need to be tested for this incident?

The blood was put into a empty water bottle, then capped thus I think this would make it airtight? And thus keeping the HIV virus alive? Then re-opened, water poured in, and drank immediately. So would this be a risk for HIV in any way, assuming there were MIRCO cuts in mouth? Again please confirm answer again with MIRCO cuts in mouth.

Answer:
Hi there, thank you for contacting the AIDS Vancouver Helpline for HIV and AIDS related information.

The simple answer to your question is no, you would not be at risk for HIV whatsoever. A capped water bottle is not airtight in the sense that the barrel of a syringe is. While the bottle is capped the blood would be exposed to the air already inside the bottle and any HIV virus would be dead and unable to infect. You have nothing to worry about whatsoever.

For your information, if you were to get some blood into your mouth you would not be at risk for HIV either. The reason for this is that our saliva actually has an enzyme in it that breaks down viruses and makes them unable to infect. So if you were to get some of the HIV virus in your mouth it would be extremely unlikely that it would infect.

I hope that answers your question and alleviates your anxiety. Keep in mind the HIV virus is actually very hard to transmit and transmission only ever really occurs as a result of certain sexual activities, injection drug use, or mother-to-child transmission.

Hello, and thank you for using AIDS Vancouver as your primary source of information about HIV/AIDS issues.

To follow-up on Arne's response, I'd like to confirm that saliva has an enzyme in it that inhibits HIV. In addition, I would like to say that taking blood into your mouth is considered a low-risk activity for contracting HIV. There have been only a few reports of infection attributed to the circumstance of taking blood into one's mouth, and usually under certain identifiable circumstances (e.g. if an individual is bleeding profusely from the mouth).

I trust that I have answered your question sufficiently. Should you have any further inquiries, please don't hesitate to write back or visit http://www.aidsvancouver.org for more information.

Sincerely,

Marta
AIDS Vancouver Volunteer.
