Ok I am totally confused. First answer was NO risk, then second answer when i said even if there were micro cuts in mouth, it became low risk, and if I am reading the third answer it says no risk............can someone please just answer one way or another without saying if this happend or if that happend, and just answer the question as I wrote it?

Here was my original question, except that I broke it down one by one. Perhaps we can answer it one by one?is it LOW risk or NO risk.............

1. if someone put blood into an empty pepsi plastic bottle, then capped it, would the HIV live in this bottle since it is capped, kinda like an airtight needle or would the air in the bottle kill it?

2. 30 seconds later, water is poured water into the same bottle and drank it. Would the water kill the hiv virus before being drank?

3. Is there ANY risk of HIV especially if one had SMALL MICRO CUTS in mouth?

4. Low or NO risk

HIV Transmission
No Risk
Ok I just read this question from start to finish below. It was labelled no risk because having any blood mixed with water would immediately kill HIV, because it doesnt live in water. And any blood in the bottle would be killed by HIV because a bottle even with a cap on it is not like a hollow needle airtight. Because it is not airtight, oxygen would kill the HIV immediately. However, whoever asked the question asked a follow up question of what if there were cuts in the mouth and now the answer is LOW RISK instead of NO risk???

What does it matter if someone had micro cuts in the mouth, if your original answers said the HIV would already be dead before even going into mouth?????If your previous answers which stated that any blood in the bottle would die immediately once exposed to air, why would having micro cuts in mouth change the risk?

I am confused on your answers, can you please re-read all of the below and answer accordingly? Is this a low risk or no risk. Basically if I read this, the question should read, if someone put blood into an empty bottle, then capped it, then a 30 seconds to a minute later poured water into the same bottle and drank it again within a minute, is their any risk of HIV especially if one had small micro cuts in mouth? I am totally confused on how this went from no risk to low risk if HIV is dead??

Here is all the other Q&A.

HIV Transmission
Low Risk
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?

HIV Transmission
No Risk
No Risk
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.

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).

Hi there,

Thanks for contacting us again.

It looks like the question was regarding actually taking blood into the mouth and not micro cuts. Your situation did NOT place you at risk. Taking blood in the mouth might be considered a risk if perhaps you were performing oral sex on someone who may be actively bleeding, or perhaps you were actually drinking massive quantities of blood. But just because there is technically SOME risk, does not mean that it is very great. You do not need to be concerned based on the situation you have described.

As for your questions regarding microcuts, the answer is no, absolutely not. Situations where one might be at risk through cuts in the mouth might be perhaps if someone was still freshly bleeding from dental work or if someone had very poor dental health and had ongoing bleeding gums. Even in those cases, the risk happens through oral sex and not drinking from a bottle that may contain some blood in it.

It is very understandable to be a young person nervous about HIV transmission, but I think in this case you have nothing to be concerned about.

I hope this clears everything up for you; however, if you have more questions, feel free to contact us again.

All the best,

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

I will answer your questions further, in the order they have been posed:

1. A Pepsi bottle is not airtight after the seal has been broken, and is nothing like a syringe. If an HIV positive individual put blood into an empty Pepsi bottle, then capped it, the HIV would die immediately upon exposure to oxygen. The HIV contained in blood dies, as quickly as the skin is broken; immediately upon exposure to oxygen. There is no risk of contracting HIV in the way you have described here.

2. 30 seconds later, the HIV contained in the blood that is in the bottle is already dead! In fact, it is impossible for HIV to live in water (H2o). There is no risk of contracting HIV, even if you drank all the water in the Pepsi bottle containing the blood.

3. If an HIV positive individual dropped their blood into an empty Pepsi bottle, filled it with water, and an individual who was HIV negative and had micro cuts in their mouth then drank the water, there would be NO risk of contracting HIV, for the above mentioned reasons.

In terms of taking blood into one's mouth as an activity, it is listed as a low-risk because under specifically identifiable circumstances, there have been a few reports of HIV infection attributed to this activity. The circumstances you have clearly described however, do not pose any risk whatsoever.

I trust I have answered your questions sufficiently. Feel free to write back to the AIDS Vancouver Helpline, or visit our website for more information.
