Some Ways You Can Contract HIV and Their Risks

[SnugOFP]

This is a good video. Deserves more viewers. All the estimates are current and based on fact unlike a lot of other sources. I tend to get really afraid when i have exposures and I check out this video every now and then just to refresh my memory on the numbers. I really do wish they did more studies on oral sex on a woman though. That is a very very common activity and a quite desriable one for many men and women and there is no hard numbers to refer to at all. :(

[statebrigaidiote]

Is AB negative blood type immune to HIV?

[AIDSvideos]

@statebrigaidiote: No. No blood type grants immunity to HIV. A few people (about 1% of Northern Europeans, for example) have genetic mutations to the receptors on their CD4 cells that make it harder for HIV to enter the cell and grant a limited degree of resistance to HIV infection. These are called CD4 delta 32 mutations or deletion mutations IIRC.

[guforules]

i've got a question thats been bothering me for a while now.

I once bought some marijuana.i don't know if it had some blood on it.i broke it up by hand, I had some cuts in my fingers.I then rolled it up and smoked my joint.

Can I have contracted HIV if there actually was some blood on the buds and I used my "damaged" fingers to break it up?

[MrDoubtfulguest]

@guforules Just get tested. HIV doesn't remain active out of the body for very long, but you sound like a worrier. Get tested, and stop worrying. (If you actually contracted HIV in the manner you describe, and you could prove it, your case would make medical history)

Or perhaps you are just joking.

[oskar092]

Can someone tell me about pre-cum? I have heard conflicting things about this.

[AIDSvideos]

@oskar092: This is Eric; I'm not a doctor. It can contain and transmit HIV.

[BlazeUp1231]

why do people say, "if you have sex with somone with HIV you get the disease straight away" ?

[bluetortilla]

What are your chances of being in a fatal car crash on the highway? Of being murdered in Oakland at midnight? Of having a fatal heart attack at age 54? We all die of something sooner or later.

[AIDSvideos]

@bluetortilla: It's true that all people die sooner or later. That's not an argument for making decisions that increase your risk of contracting an incurable virus such as HIV that can both make you very sick AND force you to take medication for the rest of your life AND cause you to die sooner that you otherwise would have.

[lv702east]

can you get it from smoking with a person that has it ????

[vanmaarwijk]

i guess i need to test every bitch im gonna date

[sorass1]

u cannot get hiv from oral sex period and kissing common people think logically hiv is a STD transmitted by unprotected vaginal/anal sex and also iv drug use and mother to child wen condoms r used effectivly meaning wen they dont break or slip they r 100 percent effective against the trnsmission f hiv

[2Warlock4You]

Hey I have a question by friend has oral herpes and has cold sores, i hit a scab that was broken and it was blood, can i contract oral herpes from that?

[AIDSvideos]

@2Warlock4You: This is Eric; I'm not a doctor. My understanding is that physical contact with an active cold sore can sometimes lead to an infection at the site of contact, so people are advised to avoid contact with active, non-healed cold sores.

[2Warlock4You]

@AIDSvideos no it wasnt a scab of the cold sore it was a scab on his elbow that was broken

[iamkingofthecastle]

Thank you so much, good straight answers

[lisapalmer850]

i had a friend who didn't have hiv and this boy did that she mess around did had hiv she got hiv 6 months later that was scarey i seen her a year later she had sores on her arm and legs what stage is she at:)

[sorass1]

kissing does not tranmit hiv oral sex does not transmit hiv neither does going down on a woman. im not a doctor but its never happened and the risks they are stating in this video are to high in alot of doctors estimation

[AIDSvideos]

@sorass1: Actually, U.S. CDC has documented cases in which people contracted HIV and are believed to only have had exposure through oral sex. Likewise, U.S. CDC has documented cases where people contracted HIV and transmission is believed to have occurred by deep kissing (although IIRC, these were cases where people may have had mouth sores as well). Cited estimates are from published peer-reviewed scientific studies.

[lisapalmer850]

if  you and your husband been been faithful for 5 years and still don't have hiv and don't mess around are they still at rick

[AIDSvideos]

@lisapalmer850: In the developed world, the median period between contracting HIV and progressing to a clinical AIDS diagnosis is 10 years. So it *is* possible that either you or your husband could have (for example) contracted HIV 5.5 years ago and not have symptoms yet. CDC recommends that ALL people in U.S. be tested for HIV at a routine doctor's office visit to be safe.

[jonykakuyo]

is it still possible to get HIV from oral sex even if the man doesn't ejaculate?

[AIDSvideos]

@jonykakuyo: Yes.

[orengepeels]

what if i have only have received unprotected oral sex ONCE from a woman who may or may not be infected. do the same statistics apply?

[AIDSvideos]

@orengepeels: Yes.

[bluetortilla]

@orengepeels that's complete bunk. extremely remote and not documented. if you know documentation please share.

[AIDSvideos]

@bluetortilla: The sources are cited right in the video. Or just go to the cited wikipedia article, which nicely organizes the risk estimates with source citations for each estimate.

[charmer2323]

u cant have oral sex with a condom it wont taste very good lol my sudjection is to make sure u and ur partner do not have stds or hiv before oral sex or any kind of sex. the problem with anal sex is the condom wants to fall off

[AdamCharlton]

people who have questions about statistics should definitely watch this video, best one i've seen! very clear

[spasiboalisher]

Oh wow!!! Never knew that Thank You so much dear for this video!!! 5+++++++

[Doktoru2007]

Hello! Do you know what's the chance of contracting HIV after kissing someone? About 2 weeks ago I got drunk and hit on a girl I didn't know (we just kissed, no sex) and now I have fever, mild headache and nausea (possible first symptoms of HIV). Should I worry?P.S.: i don't do drugs and I use condoms.

[AIDSvideos]

@Doktoru2007: Go to AIDSvideos site and click "FAQ." Read it.

[CMxDavid]

@Doktoru2007 no u can not it is no dna transfution

[ANOTHERHOLEINYOHEAD]

@Doktoru2007 No you had a hangover silly. Thats usually how you feel the next day.

[Xanimorugi]

Does the stat about unprotected insertive anal sex having a risk of 0.065% chance each time take into account rather the guy is circumcised or not? I ask because I see that the study was done in Europe and most European countries dont circumcise? So is this stat for uncut or cut penises?

[AIDSvideos]

@Xanimorugi: Good question; I don't know. We cite the sources for the estimates in the video. I'd encourage you to look up the original study and read it for further details.

[09158546253]

can HIV be transmitted in kissing?

[AIDSvideos]

@09158546253: @KateAusten27: Go to the AIDSvideos site and click FAQ.

[icns87]

i was really paranoid till i saw the oral sex section of your video... but i still would love to know, if i received unprotected oral sex just once in my lifetime, can i still get hiv that first time?(if my partner was infected)

[AIDSvideos]

@icns87: Yes, it is possible. Get tested.

[icns87]

@AIDSvideos

sorry if im being a pain... but if its possible, can you please tell me how many times it has happened in the past

[AIDSvideos]

@icns87: I have no idea. Nor is it relevant to you at all. Either you contracted HIV or you did not. How many times it did/did not happen to other people has no effect on your personal situation. Get tested. Watch our video "What's the Risk I Contracted HIV?"

[icns87]

@icns87

[Jibjub80]

@icns87 If you received unprotected oral (I'm assuming you were the one being given oral), it is highly unlikely that you have HIV from that exposure. It is still possible as youtuber "AIDSvideos" stated, but not probable. But since you stated that you were "paranoid" about it, it may be wise to get a test 3 months after exposure, for your own peace of mind.

[QuantumCerberus]

A question please !

How much the % of contracting HIV when a male ejaculate inside woman's mouth ?

Is it save for female to drink sperm ?

[AIDSvideos]

@QuantumCerberus: Watch this vid again. It clearly states a risk estimate for male-to-female transmission of HIV via oral sex. Unprotected sex is never safe. If you choose to be sexually active, use a latex barrier like a condom or dental dam (as appropriate for the act) every time for every sexual act. Watch our vid "A Brief Introduction to HIV/AIDS" for more of the basics.

[QuantumCerberus]

Use dental dam for male

Use condom for female !

Thanks pal, you saved my life...

Thanks..

[Navoistico]

is it possible to get hiv when two people who never had no sex at get hiv if they have sex with eachother countless times?

[driz27]

oral sex is no risk sex. HIV cannot be transmitted oral sex. On theory, there are risk. However, there is no scientific data that proves oral sex transmit HIV.

[AIDSvideos]

Wrong. "Yes, it is possible for either partner to become infected with HIV through performing or receiving oral sex. There have been a few cases of HIV transmission from performing oral sex on a person infected with HIV .... Studies have shown that latex condoms are very effective, though not perfect, in preventing HIV transmission when used correctly and consistently." [CDC, "Can I get HIV from oral sex?"] See our video "Some Ways You Can Contract HIV and the Risk of Each One" for details.

[Olekander]

She certainly knows her facts. She delievers the statistics in a really chilling manner. :S.

[MrSOYCABRONYQUE]

I had sex with a girl down in Mexico back in Oct while i was on vacation , now when i got back to the states a friend told me that she was hiv positive , i did not know at the time of the act , i only had sex once but first she gave me a bj with no condom and then as far as i can remember she put a condom on me and we started having sex, i was so drunk that night thats all i remember .

[AIDSvideos]

You are wise to recognize that alcohol may interfere with your ability to remember everything that happened or what the details were. Get tested. Follow the doctor's instructions for any follow-up testing. If you choose to be sexually active in the future, use a condom correctly every time. Good luck!

[difussion88]

what if the condom breaks while inserting into a woman hiv status unknown, and pull out in less than 3 seconds what are the risk?

[AIDSvideos]

Watch our vid "What's the Risk I Have Contracted HIV?"

[Olekander]

@difussion88 very low lol.

[kalashnikov567]

i don't understand how these odds could be so low to get HIV, but so many people catch it. If a condom doesn't break, and is used correctly does it pretty much make it a 0% if its vaginal.

[LUELUE818]

ane now i will engage in only protected sex untill i have a monogumus relationship. thank you doctor once again.

[LUELUE818]

i had oral sex with a man who is HIV positive and wasnt told untill after we messed around. i felt betrayed and that i was some kind of a joke to him. I really liked him and thaught it would be ok. I have done my research and your video just gave me numbers. I know i still have a chance but it is very low. I have learned my lesson and will never engage in uprotected sex. i just hope it goes well when i test in three months. THANK YOU for giving us RELATIVE information on HIV.

[stepsolar]

I LUELU818 - I was just in the same situation - i was told by an HIV positive man AFTER we messed around... Right before I gave him oral sex I ate a very dry browny that made the rough of my mouth sore too.. . plus I felt him leaking on my leg earlier (though he was not erect at all during the entire time).. But I'm wondering if you've been tested and how it went?

[godzuki444]

If i belive in your numbers , this should be wrong right ? , It would be imposible that three girls got aids at the same time.

[AIDSvideos]

Not impossible at all. The numbers in the videos are the AVERAGE-per act risk of transmission for a person who is HIV+. As the video says: "The risk of contracting HIV from a partner will also vary at different times during their infection. A person who has contracted HIV is most infectious shortly after they have acquired the virus, known as primary HIV infection. .... [The risk] can be increased or decreased by many other factors" such as STDs. The performer had just contracted HIV ....

[AIDSvideos]

... so he was probably experiencing primary HIV infection when he had sex after returning from Brazil and was at his most infectious. It's estimated that up to one third of all sexual transmissions of HIV occur during the period of primary HIV infection even though it's brief because the risk during that period is so high. Also, adult film performers usually don't use condoms while filming. So that story, far from being impossible, makes complete sense.

[godzuki444]

Wikipedia says "In 2004, a male performer, Darren James, tested positive for HIV after engaging in a scene in the video "Split That Booty 2" in Rio de Janeiro. By the end of the month it was discovered that three actresses who had worked with James shortly after his return to the United States (two of whom were involved in the same production) had also become infected with the virus" .

[AIDSvideos]

Watch "The Importance of Condom Compliance." She could have an STD (like HIV or herpes) and not even know it. If you choose to be sexually active, use a condom correctly every time.

[brandonmgd]

Isn't it counter-productive to list wikipedia as a reference? Are these figures the same for all races? Also, if the risk is so low, how is it that 1 out of 300 Americans are infected.

[AIDSvideos]

(1) We listed all sources we relied upon. We didn't use wikipedia as an original data source, but it provided a useful summary index to primary sources, so we cited it as a source. It's not counterproductive; it's honest. (2) I'm aware of no evidence that risk of contracting HIV varies by race or ethnicity. (There are specific mutations conferring partial resistance whose distribution varies by ethnicity, but the risk varies on which gene you get, not what your ethnicity is.)

[AIDSvideos]

(3) The risk of contracting HIV during a *single instance* of unprotected sex may SEEM low, but if you have sex many times (especially with a lot of different partners), it quickly adds up. About 53% of new HIV/AIDS diagnoses in America in 2005 were among gay men; it appears that a high rate of unprotected anal sex in that demographic group is contributing significantly to the total number of annual new HIV infections in the United States.

[coupleofbeers31]

Are these statistics correct? The chances seem extremely low. So this would kinda downplay the whole "it only takes 1 time" myth....

[Fatelvis2]

@coupleofbeers31 I dont know look at that german pop star the guy who got infected from her ( we assume) only had sex with her a couple of times

I have also seen posts from people who just tested positive and there sexual history was pretty brief

[Biktuh]

when you say "per exposure", do you mean per exposure strictly with a person positive with HIV? or do you mean per exposure would include those people you have had sexual contact with that are necessarily hiv+?

[AIDSvideos]

This is Eric; I'm not a doctor. "Per exposure" means "per exposure to a person who has themself been infected with HIV." e.g. if you are a man who has unprotected vaginal intercourse with a woman who has been infected with HIV (whether or not she shows HIV+ on tests yet), that is one exposure. If you have unprotected sex with a person who has never been exposed to HIV, that's not an exposure to HIV (but could expose you to many other things).

[fuckserbrussians1]

so if an hiv blood needle was on the floor a couple of weeks and u accidentaly step on it and it stabs into you, you can still contract hiv? she says that its a 0.67 percent chance

[AIDSvideos]

This is Eric; I'm not a doctor. No, the 0.67% chance she cited related to needle sharing by injection drug users. This generally relates to sharing of a needle within a short period of time (e.g. minutes or hours). If a needle had been "on the floor a couple of weeks," the blood should have dried and the HIV should have "died," so the risk of HIV transmission would probably be reduced. BUT REGARDLESS, DON'T EVER SHARE OR REUSE NEEDLES FOR ALL KINDS OF REASONS INCLUDING OTHER DISEASES THAN HIV.

[vainandproud]

last question...............WHAT EXACTLY IS THE RATE AT WHICH CONDOM FAILURE OCCURS DURING RECEPTIVE ANAL SEX? like how ofteeeeeeeeeeeen does it happen? and what if i use a condom and i dont let him ejaculate inside me? could i still get infected from precum if the condom breaks inside me? how safe issssssssss this if i follow these things?

[vainandproud]

i'm bottom so i have sex with tops...what i don't understand is...if i have sex with a top that is always a top and always uses protected sex....then how am i going to get the disease?

i know both bottoms and tops get aids, but bottoms at a much higher rate....but isnt it safer then to have sex with a top?

i just dont understand how i could get sick if i have sex with a guy that has never had unprotected receptive anal, is a straight-topper and always used condoms?!

[AIDSvideos]

This is Eric; I'm not a doctor. You're making a false assumption that using a condom GUARANTEES a person won't contract HIV. That's simply not correct. A person could have always been a "top" and used condoms and nonetheless contracted HIV and also pass it on to you as well. The risk is reduced by condoms significantly, but is not zero. So be honest with yourself about that and don't kid yourself that you COULDN'T contract HIV.

[vainandproud]

you are a really bad moderator! answer my damn questions, isn't that your job or are you discriminating because i'm gay?

1) is the risk from kissing 1 in 20,000 too? since the risk from getting hiv from someone's mouth while getting head is 1 in 20, 000? is it the same risk of getting hiv from someone's mouth while kissing?

[AIDSvideos]

As I noted by private message to you already: (1) It is NOT my job to research & answer your questions, I'm a volunteer (2) YouTube's comment facility is glitchy and slow -- your comment just showed up now after a 5 day delay; yell at YouTube, not me. I'm really not inclined to spend my late night researching answers for someone who's verbally abusive. Learn some basic politeness and start doing research online about your risks yourself instead expecting others to do it for you.

[ForJustice007]

Studies say that most people got HIV through unprotected sex

In the countries with lower HIV infection rates 1 from 1000 or 1 from 2000 persons is infected with HIV.Considering that the chances for a man to contact HIV from an infected woman through unprotected vaginal are 1 to 2000 and 1 to 200 from infected man to a woman, I don't understand how there are so many infected persons.

That means some people had and still have unprotected sex hundreds or thousands of times during their lifetime.

[Grupperhead]

If I masturbate in the shower and ejaculate, is it dangerous for my brother to take a shower right after me? Can he get in contact with my semen even if I think I've washed it away? Help!

[navyseal100]

HIV DIES AFTER CONTACT WITH AIR

[AIDSvideos]

See our video "HIV in the Household."

[vainandproud]

Does this mean a person has a 1 in 20,000 chance of getting HIV from kissing someone?

[patricia1patricia]

i'm sorry but i cannot agree with these statistics.

1/1538 chance...1/200 chance.... uh uh.

I was told and i know that "You have unprotected sex with a HIV + person THEN you GET AIDS...PERIOD"

[AIDSvideos]

Whoever told you that meant well but didn't know the statistics on per-exposure risk of contracting HIV. Having unprotected sex one time with an HIV+ person doesn't guarantee you will contract HIV. (I'm *not* recommending unprotected sex with anyone, by the way!) The statistics we cite are estimates from studies published in peer-reviewed scientific journals.

[huytrankiem]

She did not assess the risk from FINGERING! If I finger the vagina of the poz and I have one wound at the same time, my wound is not bleeding but festering and painful. Am I at a risk?

[huytrankiem]

I have watched the videos but I have not seen the risk of catching HIV from fingering the vagina with the wound on the fingers.

I had a wound on my finger. I accidentally cut my finger while doing shaving( in the night before the incident). The wound was not bleeding when I fingering the vagina, but it was a little festering and painful.

Could I catch HIV this way?Was there a "layer" formed to protect my body once the wound stopped bleeding?

[huytrankiem]

She did not mention the digital sex( fingering vagina), I am worried over the incident because I fingered one woman with the wound on my finger. it was not bleeding but It was burning and discharging matter. Please assess my risk,

Thank you,

[mylastq]

My second question.

2) Does manual masturbation carry ZERO risk of HIV infection given that:

a) my partner's semen does not come into contact with my penis, and vice versa, and

b) there are no OBVIOUS cuts on my hands?

By obvious cuts, i am referring to cuts or wounds i can see with my naked eye.

Are there invisible cuts on your hands that you are unaware of?

What about possible cuts under your fingernails at the tips of your fingers?

(cont'd)

[mylastq]

(cont'd) Basically, how risky is deep kissing if you are engaging in deep kissing with a person of unknown HIV status? Is it so low risk that you don't need to worry about it or get tested? Is it so low risk that it carries the same risk as having a car accident when you're on the road? Or is it of higher risk?

[mylastq]

(cont'd) However, as we both know, it is hard to really determine the risk of deep kissing, because most individuals don't stop at kissing and continue to riskier types of sex. If insertive oral sex has a risk of 1 in 20,000 of HIV transmission due to the possible presence of blood in the person giving head entering the system of the insertive partner's urethra or small scraps on his penis...can we say that deep kissing as well has a 1 in 20,000 risk of HIV transmission each time? (cont'd)

[mylastq]

Dear Eric,

I am a MSM.

I have 3 questions.

1) I understand that deep kissing is regarded as a low risk sexual activity. However, the CDC recommends not engaging in deep kissing with a person who is known to be infected, due to the possible presence of blood in the mouth. There has been only one possible case of HIV infection documented so far that was due to deep kissing. (cont'd)

[ernonno]

I don't quite get one thing. If a girl has HIV, and you have umprotected sex with her your chances to get infected are 1 in 2000 or the video meant that you have 1 in 2000 chances thet she MIGHT have HIV, and then get infected 100% of the times? Please answer, I don't get it.

[AIDSvideos]

The first. The video is saying that IF the woman is HIV+ and a man has unprotected vaginal sex with her, he has 1 chance in 2000 each time of contracting HIV.

[ernonno]

Thank a lot. I thought the percentage was a lot higher before.

[bookofenoch34]

Ive heard a lot of conflicting numbers, how long exactly can HIV survive in a blood smear that is exposed to air?

[AIDSvideos]

This is Eric; I'm not a doctor. So long as the blood remains wet, you should assume that HIV within the blood remains infectious. However, HIV "dies" within minutes of the blood fully drying out or of being on a dry surface like a toilet seat.

[bookofenoch34]

I also have a question, I've heard many conflicting facts about the amount of time HIV can live when exposed to air, you probably have access to a lot of peer reviewed articles on the subject, what do you think? I had a needle stick injury and I saw what i though was a tiny spec of dried blood about 1 mm that was not on the needle itself but on the plastic at the base of the needle, assuming the person has HIV am I at risk?

[AIDSvideos]

This is Eric; I'm not a doctor. I've read in the past that HIV is believed only to remain viable for about 10 minutes when outside of the human body or wet human fluids. (e.g. if on a dry surface in isolation) You should ask your doctor about your personal risk from the needle stick exposure you may have had and how you should be tested and when. Worst case, there could have been wet fluid in the needle that you didn't see.

[AIDSvideos]

Best case, if the person/people whose blood was on the needle hadn't been exposed to HIV, you weren't exposed either. Good luck!

[PAPILLION71]

I'm not having anymore sex period, i'm just going to stick to masturbating on over internet, in the safety of my home. I saw a lot of aids videos all day today-forget it man, too many people have aids now, the world is starting to suck.

[jrlynn79]

@PAPILLION71 Amen brotha ;)

[BlazeUp1231]

@PAPILLION71 brother i agree can you imagine catchin aids, fuck that its fuckin torture

[thunderflash82]

I heard if you're circumcised you have a lower chance of infection. Is that true?

Another question. I fucked a girl in the ass unprotected. If she had HIV, would her shit be contagious?

[AIDSvideos]

Controlled clinical studies have shown that circumcised males are about 50% less likely to contract HIV through heterosexual sex than uncircumcised males. And yes, a man can contract HIV through unprotected anal sex with a woman. However, to be precise, I don't think it's any HIV shed in the feces that poses the risk so much as direct contact between the penis and the mucous membranes of the anus.

[thunderflash82]

When you say per exposure, do you mean per ejaculation?

[AIDSvideos]

No. Ejaculation is not necessary for HIV transmission to occur. I mean per instance of contact. e.g. needle sharing one time is one contact, unprotected sex is one contact, etc.

[seekingstats]

This video was much more helpful than "What's the Risk I Have HIV/AIDS?". I was in a monogamous relationship, w/ someone who hid a heroin addiction. Though he swears that he never shared needles, after I discovered his web of lies that hid his addiction, I know that I cannot trust him. I am waiting for the results of my test, but not knowing is keeping me up at night. I feel stupid for ever trusting him, though we used condoms most of the time, I can't help but think about the times we didn't.

[patricks98]

so if there was an ejaculation or if there wasnt, either way it is an instance of contact???????

[AIDSvideos]

This is Eric; I'm not a doctor. See the wikipedia article on HIV and its table with these statistics; then refer to the specific scientific studies that are referenced for details on how the numbers were calculated. In short, you should consider one incident an exposure whether or not ejaculation occurred.

[JohnnyRock2000]

Now I understand how that slut that lives in the apartment beneath mine still hasn't got AIDS.

[AIDSvideos]

Please avoid the use of stigmatizing terms.

[Snolliot]

so the link of the massive spread must be:

a man getting poked in the butt get hiv, poke a man in the butt spread it and also poke women in the butt.

[Snolliot]

source Wikipedia? UHuh maybe not so reliable after all

[AIDSvideos]

Cheap shot. We are not citing Wikipedia as a primary source at all. The primary sources are the peer-reviewed scientific & medical journals we provided citations for. We're simply referencing Wikipedia since it did a nice job of pulling together the relevant references in one place.

[RionKaneshiro]

You have a little bug for the unprotected insertive oral sex.

Dr. Kuhn said its 0.005% bit it's stated 0.01%

So I think someone forgot to change the value ;)

[axvenzo]

well, nice to know!

great informative video, hope the numbers are right... have fun but now you know...!

[DefineYourTerms3]

If risk sounds low, remember that it is easier to get other STDs than HIV and that risks skyrocket with partners who have mutliple partners, i.e., prostitutes.

[AIDSvideos]

Yep -- HIV is not the only thing out there to worry about!

[dahiya1]

since HIV is not the only thing to worry about and it easier to get other STD why only focus on HIV?......and if the risk is that low why is it much spread?

[AIDSvideos]

HIV can kill you and is incurable. Other STDs generally aren't fatal (herpes, HPV) or are generally curable (gonorrhea, syphilis). Therefore we're focusing on HIV.
