If I Get Infected Fluid From An Hiv
No, HIV is not always passed on from someone living with HIV. There are lots of reasons why this is the case. For example, if the HIV-positive person is on effective treatment it will reduce the amount of HIV in their body. If a doctor confirms that the virus has reached undetectable levels it means there is no risk of passing it on.
If youre concerned that youve been exposed to HIV you may be eligible to take post-exposure prophylaxis , which stops the virus from becoming an infection. However its not available everywhere and has to be taken within 72 hours of possible exposure to be effective.
Its really important to take a HIV test every time you think you have been at risk of HIV.
How Long Does Hiv Live Outside The Body In Blood
HIV in blood from something like a cut or nosebleed can be active for several days, even in dried blood. The amount of virus is small, though, and unable to easily transmit infection.
HIV survival time in fluid outside of the body can increase when a small amount is left in a syringe. After an injection in someone with high levels of HIV, enough blood stays in the syringe to transmit the virus. Since its inside a syringe, the blood isnt as exposed to air as it is on other surfaces.
According to the , when the temperature and other conditions are just right, HIV can live as long as 42 days in a syringe, but this typically involves refrigeration.
HIV lives the longest in a syringe at room temperature, but can still live up to

How Long Does Hiv Survive Outside The Body
In general, the virus doesnât live long once itâs outside of a human body. Studies show that HIV grown in the lab, when placed on a surface, loses most of its ability to infect — 90% to 99% — within several hours. And the level of virus tested was much higher than whatâs found in bodily fluids. So contact with dried blood, semen, or other fluids poses little risk.
Tiny amounts of HIV have been found in saliva, poop, sweat, and tears. But research shows it poses little risk.
The virus canât survive in water, so you donât have to worry about swimming pools or hot tubs.
One study found HIV can live in used needles for over a month if the temperature and conditions are just right. That means sharing needles or syringes, like during drug use, raises your risk of infection.
So How Long Can Hiv Live Outside The Body
HIV or human immunodeficiency virus is a virus that attacks white blood cells in the body so people will easily get other diseases. This HIV virus must be in the pH or state in accordance with the condition of the virus in order to survive as in the blood.
Therefore an HIV virus cannot survive or live outside the body as it is in the sweat or blood that has come out in the body. According to research that there is an HIV virus that is in the blood that has come out in the body and mixed with other conditions is very rare even almost nothing to be able to transmit the virus to the people around.

For How Long Does The Hiv Virus Survive Outside The Body
Answered by: Dr Anuj Sharma | World Health Organization, Country Office for India, New Delhi
Q: Why is it said that the HIV virus dies once it is outside the body? All viruses become inactive once outside the body – is that not so, and moreover, as far as I know a virus never dies and can always get into its reproduction mode once inside the host cell. So, in this regard I want to know that if suppose I put a drop of HIV infected blood on a slide, keep it exposed for some time, say a couple of hours, and then if I bring an open wound in contact with the dried blood, will the person get infected with HIV?
Isnt Hiv Only A Risk For Certain Groups Of People
Like most illnesses, HIV doesnt discriminate between types of people and the infection can be passed on to anyone via one of the ways mentioned above.
Some people are more vulnerable to HIV infection if they engage regularly in certain activities that are more likely to transmit the virus. However, its a common misunderstanding that HIV only affects certain groups.
While not everyone has the same level of HIV risk, everyone can reduce their risk of infection.

How Long Can Hiv Survive Outside The Human Body
Generally the virus does not survive at the room temperature due to its fragile nature. Scientific studies have found that HIV can sometimes survive in dried blood at room temperature for up to six days.
Generally, when people ask the question, How long can HIV survive outside the body? it means they have come into contact with some body fluid that they think might contain HIV, and are worried about transmission. Almost always these questions are about casual contact, and we know the virus is not transmitted except during unprotected sex, sharing needles, or through significant and direct exposure to infected blood. The length of time HIV can survive outside the body depends on: The amount of HIV present in the body fluid, and What conditions the fluid is subjected to. In a laboratory, HIV has been kept viable for up to 15 days, and even after the body fluid containing it had dried. However, these experiments involved an extremely high concentration of the virus that was kept at a stable temperature and humidity. These conditions are very unlikely to exist outside of a laboratory. HIV is very fragile, and many common substances, including hot water, soap, bleach
Exploring Hiv Transmission Rates
World Health Organization , about 36.7 million people worldwide lived with HIV as of 2016. Still, thanks to antiretroviral therapy , people with HIV are leading longer, better quality lives. Many of these strides have been made in the United States.
To help reduce the risk of transmission, its important to understand how the virus is spread. HIV is only transmitted through bodily fluids, such as:
- blood
- semen
- breast milk
Learn which type of exposure is most likely to transmit the virus and how antiretroviral drugs are making a difference.
, direct blood transfusion is the route of exposure that poses the highest risk of transmission. While uncommon, receiving a blood transfusion from a donor with HIV may increase the risk.
The CDC also discusses HIV transmission risk in terms of how many times the virus is likely to be transmitted per 10,000 exposures. For example, for every 10,000 blood transfusions from a donor with HIV, the virus is likely to be transmitted 9,250 times.
Since 1985, however, blood banks have adopted stricter screening measures to identify blood with HIV. Now all blood donations are carefully tested for HIV. If they test positive, theyre discarded. As a result, the risk of contracting HIV from a blood transfusion is very low.

How Could You Get Hiv From Contact With Blood
The risk of HIV transmission through blood comes when the person has a detectable viral load and their blood enters another persons body or comes into contact with a mucous membrane. These are parts of the body with wet, absorbent skin such as the:
- eyes
- inside of the anus
- mouth.
Theres also a risk if blood from a person who has a detectable viral load comes into contact with a cut or broken skin, giving HIV a way through the skin and into someones bloodstream. If blood gets onto skin that isnt broken, there is no risk.
In a medical setting, its possible for HIV to be transmitted by someone accidentally cutting themselves with a blade or needle they have used to treat a person living with HIV.
This is called a needlestick injury. The risk of being infected in this way is very low. However, if someone thinks they have been exposed to HIV through a needlestick injury, post-exposure prophylaxis may be an option.
Frequently Asked Questions About Hiv/aids
HIV can be detected in several fluids and tissue of a person living with HIV. It is important to understand however, that finding a small amount of HIV in a body fluid or tissue does not mean that HIV is transmitted by that body fluid or tissue. Only specific fluids from an HIV-infected person can transmit HIV. These specific fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the blood-stream for transmission to possibly occur.
In the United States, HIV is most commonly transmitted through specific sexual behaviors or sharing needles with an infected person. It is less common for HIV to be transmitted through oral sex or for an HIV-infected woman to pass the virus to her baby before or during childbirth or after birth through breastfeeding or by prechewing food for her infant. In the United States, it is also possible to acquire HIV through exposure to infected blood, transfusions of infected blood, blood products, or organ transplantation, though this risk is extremely remote due to rigorous testing of the U.S. blood supply and donated organs.
For more information, see: How safe is the blood supply in the United States?
For more information on latex condoms, see “Male Latex Condoms and Sexually Transmitted Diseases.”
In women, the lining of the vagina can sometimes tear and possibly allow HIV to enter the body. HIV can also be directly absorbed through the mucous membranes that line the vagina and cervix.

Semen Vaginal Fluids And Anal Mucus
If an HIV positive person has sex without a condom, and they do not have an undetectable viral load, HIV can get into the other persons blood because it lives in the semen, vaginal fluid and anal mucus. There does need to be a tear or graze in the other person for the HIV to enter into their body. A condom stops any fluid being passed to the other person, and it also stops unwanted pregnancy and getting other sexually transmitted infections.
Perceived Vs Documented Risk
A perceived risk is one that is based on belief rather than fact and persists despite the unlikeliness of the event ever occurring. By contrast, a documented risk is based on statistical evidence of something actually occurring. Where a perceived risk is about theory, a documented risk is about the fact.
With regards to HIV, the potential to infect does not translate into an actual risk unless the exposure satisfies four specific conditions:
- There must be body fluids in which HIV can thrive. This includes semen, blood, vaginal fluid, and breast milk. HIV cannot thrive in parts of the body that have high acidity .
- There must be a route by which HIV can enter the body. This includes sexual intercourse, shared needles, occupational exposure, or transmission from mother to child.
- The virus must be able to reach vulnerable cells inside the body. This requires the rupture or deep penetration of the skin and/or the absorption of the virus through the mucosal tissues of the vagina or anus. Scrapes, abrasions, and skin prick do not offer the deep penetration needed for an infection to occur. HIV cannot pass through intact skin.
- There must be sufficient quantities of virus in the body fluids. Saliva, sweat, and tears all either contain enzymes the inhibit HIV or have a pH hostile to HIV.
Unless all of these conditions are satisfied, an HIV infection simply cannot occur.

Causes Of Hiv Infection
HIV is found in the body fluids of an infected person. This includes semen, vaginal and anal fluids, blood and breast milk.
It’s a fragile virus and does not survive outside the body for long.
HIV cannot be transmitted through sweat, urine or saliva.
The most common way of getting HIV in the UK is through having anal or vaginal sex without a condom.
Other ways of getting HIV include:
- sharing needles, syringes or other injecting equipment
- transmission from mother to baby during pregnancy, birth or breastfeeding
The chance of getting HIV through oral sex is very low and will be dependent on many things, such as whether you receive or give oral sex and the oral hygiene of the person giving the oral sex.
How Long Does Hiv Live Outside The Body In The Environment
HIV cant survive for long in the environment. When fluid leaves the body and is exposed to air, it begins to dry up. As drying occurs, the virus becomes damaged and can become inactive. Once inactive, HIV is dead and no longer infectious.
Some research show that, even at levels much higher than usually found in the bodily fluids and blood of people with HIV, 90 to 99 percent of the virus is of being exposed to air.
However, even though exposure to the environment can inactivate the virus, at least several days , even as the fluid dries.
So, can you get HIV from a surface, such as a toilet seat? In short, no. The amount of active virus that would be able to transmit an infection in this scenario is negligible. A case of transmission from a surface has never been reported.

How Long Can Hiv Survive Outside The Body
Once outside the body, HIV usually cant survive for very long. Coming into contact with blood or semen that has been outside the body doesnt generally pose a risk for HIV transmission.
Similarly, the risk of passing on HIV to someone else if you have a detectable viral load and cut yourself is also very low. Wash away any blood with soap and hot water and cover the wound with a sticking plaster or dressing.
How Hiv Can Spread
The most common ways people contract HIV in the United States are through sharing equipment when injecting drugs and having anal or vaginal sex without barrier contraceptives. Anal sex poses a higher risk than vaginal sex, as there is a greater chance of tissue damage.
Although it is less common, HIV may pass to an infant during pregnancy, birth, or breastfeeding.
In extremely rare cases, HIV may spread if blood comes into contact with an open wound. There is a chance of this occurring if partners engage in open-mouth kissing, and both have bleeding gums or open sores within the mouth.
However, saliva that does not contain blood cannot transmit HIV. People cannot get HIV from closed-mouth or cheek kissing.
People can reduce or eliminate the chance of contracting HIV by using barrier contraceptives or taking preventive HIV therapy, known as pre-exposure prophylaxis .
PrEP is a pill that a person can take once a day to minimize the chance of contracting HIV. It may be helpful for those who:
- have a partner with HIV
- have a partner with an unknown HIV status
- have multiple partners

Can Herbal Medicine Cure Hiv
No. Some people choose to take alternative forms of medicine, such as herbal medicines, as a natural way of treating HIV. However, herbal remedies do not work.
Taking herbal medicines can be dangerous as they will not protect your immune system from infection. They may also interact poorly with antiretrovirals if you are taking them alongside treatment. The only way you can stay healthy when living with HIV is to take antiretroviral treatment as prescribed by your doctor or healthcare professional, and to attend viral load monitoring appointments to make sure your treatment is working.
How Do You Get Hiv From Semen Or Vaginal Fluid
Body fluids including semen and vaginal secretions can contain HIV. If a person has HIV and a detectable viral load, HIV can passed on to someone if their semen or vaginal secretions get into the body of a sexual partner during vaginal or anal sex.
If a man has HIV and a detectable viral load, one of his body fluids where the virus is found is his semen.
If he has a detectable viral load and his semen gets into the body of his sexual partner during sex, then HIV can get into the other persons bloodstream.
Pre-cum also contains HIV this is why there is a risk of infection even if a man pulls out of his partner before he ejaculates.
If a woman has HIV and she has a detectable viral load, one of her body fluids where the virus is found is in her vaginal secretions.
If these come into contact with a penis during sex, then HIV could be transmitted. The virus in her secretions can enter through the delicate skin of the penis or foreskin.

Saliva Sweat Tears Urine Or Feces
HIV cannot be spread by sharing drinking glasses or by casual kissing. The risk of spreading the virus through “deep” kissing in which large amounts of saliva are exchanged is extremely low. Only one unproven case has ever been reported.
No cases of HIV spread have ever been reported after a person has come in contact with the sweat, tears, urine, or feces of an HIV-infected person.
