What Should I Do If I Need To Clean Up Blood
HIV does not usually survive long outside of the body, but contact with blood should be avoided.;
To clean up blood that has been spilled, wear rubber gloves and mop up the liquid using bleach and warm water . Use warm, soapy water to clean away blood spilled on someones body.
Put the waste, used gloves and bloodied clothes in a plastic bag, seal and throw away.
What If There Is An Actual Or Suspected Exposure To Hiv
The decision to begin a post-exposure prophylaxis for HIV infection is based on the judgment of a health care professional and should be a joint decision with the exposed worker. PEP often involves taking a combination of 2 or 3 antiretroviral drugs for about 4 weeks. PEP can help reduce, but not eliminate, a personâs risk of infection. The PEP should begin as soon as possible, as it may be less effective if started more than 72 hours after exposure.
Occupational Groups Risking Exposure to the AIDS Virus
The occupational groups listed below risk exposure to HIV in the workplace. The table that follows suggests preventive measures for these groups. For many situations, using all protective barriers listed in the table is not necessary, but workplaces should always make them available in case of emergency response scenarios.
Surgeons, Nurses and Nurses Aides
Surgeons, nurses and nurses’ aides should take precautions to avoid needlestick injuries, cuts with sharp instruments and exposure through skin lesions to potentially infectious blood and body fluids.
Physicians and Laboratory Workers
These people continuously handle infectious samples. Doctors, in diagnosing HIV patients, carry out physical examinations and collect blood samples. Laboratory technicians analyze potentially infected samples.
Embalming the bodies of persons with a HIV infection presents a risk because HIV can live for hours in a deceased body.
Hiv Transmission Can Occur After Only One Exposure
Assigning an actual percentage to the riskiness of a certain activity is a tricky business. While statistics may suggest that there is only a 1-in-200 chance of getting infected by such-and-such activity, that doesnt mean you cant get infected after only one exposure.
Instead, a 0.5%;per exposure risk is meant to indicate that an average of one infection will occur out of 200 people who engage in a particular activity. It doesnt mean that;you need to do something 200 times in order to get infected.
Its important to remember that risk estimates are based on two factors and two factors alonethat one person has HIV and the other doesnt. Additional co-factors, such as co-existing sexually transmitted infections , general health, and the infected persons viral load,;can further compound risk until a;low-risk activity is suddenly considerably higher.

Hiv Transmission And Risk: Separating Fact From Fiction
Its much harder to transmit HIV than most people think.Thanks to years of dedicated work by scientists and researchers, we now have a solid understanding of the way HIV passes from person to person.
Unfortunately, much of our society is still clinging to harmful, outdated myths about HIV transmission.
In a recent survey, 28% of millennials and Gen Zers said they would be reluctant to hug, talk to, or even associate with someone living with HIVdespite the fact that none of those behaviors pose any risk.
Thankfully, we have good science to combat misinformation about the way HIV passes from one person to another. In this resource guide, well break down the science of HIV transmission and dispel harmful misconceptions. Well also explain why certain groups of people are more likely to be living with HIV than others, and well offer practical steps you can take to keep yourself HIV negativeor, if youre living with HIV, to prevent onward transmission of the virus.
If youre reading this guide because you were recently diagnosed with HIV, remember that you will be OK. Powerful medicines can help you live a long and healthy life. When it comes to HIV transmission, you shouldnt be afraid to hug, kiss, and touch your loved ones. You will not hurt them.
Which Bodily Fluids Can Pass Hiv
Bodily fluid is a blanket term that refers to any of the liquids floating around inside the human body. Were talking blood, sweat, tears, semen, vaginal fluids, urine, and all the rest.
HIV does not spread throughout the body evenly. Some bodily fluids have it, but most dont. In fact, HIV can only be transmitted to another person through these three types of bodily fluids:
- sexual fluid
- breast milk
HIV cannot be passed from person to person via other fluids like tears, saliva, vomit, or feces. This is an incredibly important point about HIV transmission that is often misunderstood.
For decadesand still todaypeople have worried they might catch HIV from a toilet seat, perhaps by touching the urine or fecal matter of an HIV-positive person. This absolutely does not happen.
People have also worried they might catch the virus from the saliva of an HIV-positive person who kisses them or spits on them. In fact, this fear is so pervasive that some states have made it a felony for people with HIV to spit at or bite someone else. Those laws are based on outdated science.
The only way it would be possible to transmit HIV through saliva is if the HIV-positive person had bleeding gums or sores, and somehow that bloody saliva got into the bloodstream of the HIV-negative person. However, experts agree that the risk of this happening is so statistically tiny that its not worth worrying about.
So, to recap:

Necessary Conditions For Hiv Infection
HIV is a relatively fragile virus, which is not spread by casual contact. HIV is not easy to catchit must be acquired. In order for HIV to be transmitted, three conditions must occur:
- There must be an HIV source.
- There must be a sufficient dose of virus.
- There must be access to the bloodstream of another person.
Body Fluids That Can Transmit HIV
Anyone infected with the virus is potentially a source of HIV infection. Transmission occurs primarily through infected blood, semen, vaginal secretions, or breast milk. Sweat, tears, saliva, urine, and feces are not capable of transmitting HIV unless visibly contaminated with blood.
In settings such as hospital operating rooms, other fluids such as cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, and amniotic fluid may be considered infectious if the source is HIV positive. These fluids are generally not found outside the hospital setting. Therefore, the most common body fluids considered potentially infectious for HIV are blood, semen, vaginal secretions, and breast milk.
The concentration and amount of HIV necessary for infection to occur is called a sufficient dose.
Access to another persons bloodstream involves behaviors or circumstances that place someone at risk for infectious fluid entering their bloodstream. The most common of the risk behaviors are unprotected sexual intercourse with an infected person and use of contaminated equipment for injecting drugs.
What We Know About Injecting Drugs
The risk for getting or transmitting HIV is very high if an HIV-negative person uses needles, syringes, or other drug injection equipment after someone with HIV has used them. This is because the needles, syringes, or other injection equipment may have blood in them, and blood can carry HIV. Likewise, youre at risk for getting or transmitting hepatitis B and C if you share needles, syringes, or other injection equipment because these infections are also transmitted through blood.
In 2017, 6% of new HIV diagnoses in the United States were attributed to injection drug use and 3% were attributed to injection drug use and male-to-male sexual contact . On average, an HIV-negative person has about a 1 in 160 chance of getting HIV every time they share needles, syringes, or other injection equipment with a person who has HIV.
More Information There may be extremely tiny amounts of blood in syringes or works that you may not be able to see, but could still carry HIV. Be aware that HIV can survive in a used syringe for up to 42 days depending on temperature and other factors.
There are medicines to treat hepatitis B. If youve never had hepatitis B, theres a vaccine to prevent it. There are medicines to treat hepatitis C, but they arent right for everyone. Theres no vaccine to prevent hepatitis C. Talk to your health care provider to learn more about hepatitis B and C.

How Do I Protect Myself And Others
Teach children to never touch used needles, syringes or condoms, and to tell an adult immediately if they find one. It is important to dispose of a used condom, needle or syringe quickly and carefully. Always wear clean disposable gloves or use tongs, pliers or another object to pick up used condoms, needles and syringes. Discard condoms in a plastic bag. Needles and syringes should be placed in a metal or plastic container with a puncture-proof lid and disposed of in the regular garbage or according to local by-laws. Always discard used gloves in a plastic bag and wash your hands carefully with warm water and soap. If the item used to remove the condom, needle or syringe is not disposable it should be disinfected with bleach.
Hand washing is the best way to prevent the spread of germs. Wash your hands carefully with soap and warm water for at least 15 to 20 seconds. Waterless alcohol-based hand rinses can be used as long as hands are not heavily soiled.
Wash your hands before and/or after the following activities:
- before preparing food and after handling uncooked foods;
- before eating or smoking;
- before and after providing first aid;
- before and after providing care to a person;
- after using the toilet or changing diapers;
- after handling blood or body fluids; and
- after coughing or sneezing.
Means And Requirements For Hiv Transmission
People may become infected with HIV if they engage in specific risk behaviors or if they are exposed through needlestick injuries . Other blood contact with mucous membranes or non-intact skin provides a possible, but not probable, chance of transmission.
HIV is transmitted through:
- Unprotected anal, vaginal, and oral intercourse
- Sharing needles or other injection equipment
- A mother passing the virus to her baby either before or during birth
- An infected woman breastfeeding her infant
- Accidental needlestick injuries, or infected body fluid coming into contact with the broken skin or mucous membranes of another person
- A transfusion prior to 1986 of HIV-infected blood or blood products
In extremely rare cases, HIV can be transmitted by sharing razors or toothbrushes, if infected blood from one person was deposited on the toothbrush or razor and the blood entered the bloodstream of another person.
The transmission of HIV depends upon:
- The availability of the infectious agent in sufficient quantity
- The viability of the infectious agent
- The virulence of the infectious agent
- The ability of the infectious agent to reach the bloodstream, mucous membranes, or broken skin of a potential host
One of the predictors of the infectious level of an HIV-positive person is viral load, which is how much HIV is present in the bloodstream. Studies show a clear connection between higher viral load in the blood and increased transmissibility of HIV.

Tattoos And Body Piercings
- There are no known cases in the United States of anyone getting HIV this way.
- However, it is possible to get HIV from tattooing or body piercing if the equipment used for these procedures has someone elses blood in it or if the ink is shared. This is more likely to happen when the person doing the procedure is unlicensed because of the potential for unsanitary practices such as sharing needles or ink.
- If you get a tattoo or a body piercing, be sure that the person doing the procedure is properly licensed and that they use only new or sterilized needles, ink, and other supplies.
Ways Hiv Can Be Transmitted

Hiv In Vaginal Fluids
While HIV can spread via vaginal fluids, the virus tends to exist in smaller concentrations than it does in blood and semen.
It is not clear why this is the case, but it appears that hormones and the types of cells in the genital tract may play a role.
Breast milk contains HIV in lower concentrations than blood or semen.
A baby can contract HIV through breast milk, so the CDC recommend that people with HIV do not breastfeed, regardless of antiretroviral therapy or viral load.
HIV can also transmit to a baby through pregnancy or birth. However, this is becoming less common with recent developments in care.
If a person with HIV is receiving effective antiretroviral therapy, and they give HIV medicine to the baby for 46 weeks after delivery, the risk of the baby contracting HIV can be
How Is Hiv Not Passed From One Person To Another
You may have just read the section above and thought to yourself: Wait, that seems like a really short list of ways HIV gets transmitted. What about mosquitoes? Blowjobs? Kissing? Sharing food or utensils?
As weve previously discussed in this guide, there are a lot of myths and misconceptions about HIV transmission. At some point, people without HIV may worry they have been exposed to the virus. And when people get freaked out about their health, they tend to start scouring the internet for answers.
At TheBody, weve spent the past 25 years fielding questions about HIV exposure fears and talking with experts about the realities of HIV risk. So we know an awful lot about the HIV transmission concerns people tend to have in common.
These are the top five recurring fears about HIV transmission that are way, way more than theyre cracked up to be:

How To Be Safe When Coming Into Contact With Infected Blood
A condom will act as a barrier against any contact with blood during sex.;
As well as sex, sharing equipment for injecting drugs is a way blood can get into someones body. This can be avoided by using fresh needles and not sharing needles, syringes and other equipment.;
If a woman has HIV, her menstrual blood also carries a risk of transmission if she has a detectable viral load.;
If youre HIV negative and taking pre-exposure prophylaxis youll be protected against getting HIV if you come into contact with infectious blood.
Why Do Guys Use Vaseline
Vaseline, or petroleum jelly, is an oil based ointment that people can use to moisturize and soften dry skin. People might want to use Vaseline as a sexual lubricant because it has a soft and smooth texture. Vaseline does not get sticky or dry out, which in theory also makes it a good lubricant option

What You Can Do
Not having sex is a 100% effective way to make sure you dont get or transmit HIV through sex. If youre sexually active, you can lower your risk by choosing sexual activities that carry a lower risk for HIV than anal sex. You can also do other things to reduce your risk, including taking medicine to prevent or treat HIV and using condomsthe right way, every time. Condoms and medicine to prevent or treat HIV are highly effective at preventing HIV if used correctly. But the medicines are much less effective if you dont take them daily as prescribed, and condoms can sometimes break or come off during anal sex. Using a water-based or silicone lubricant can help prevent condoms from breaking or slipping.
