How Long Does Hiv Live Outside The Body In Blood

How soap kills the coronavirus

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 Hiv Can Spread

Progress on drinking water, sanitation and hygiene in schools: Special ...

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

Path To Improved Health

There are many ways to prevent occupational exposure to HIV. To start, health care workers should treat all body fluids the same way. You should assume they are infected and take precautions:

  • Use protective covering, such as gloves and goggles. You always should do this when dealing with blood and body fluids.
  • Wash your hands and other skin areas right after contact with blood and body fluids.
  • Be careful when handling and disposing of needles and sharp instruments.
  • Use available safety devices to prevent needle stick injuries.
  • Be aware of your employers post-exposure processes.

If an exposure does occur, follow these basic steps:

  • For a skin puncture, induce bleeding at the wound site. Do this by applying gentle pressure around the wound as you wash the area with soap and water.
  • For a skin or mucous splash, rinse the area well with water.
  • Get the infected persons information. This includes name, address, phone number, and HIV status. If they are a patient, get their doctors contact information.
  • Notify your supervisor and coworkers. If your place of work has other procedures in place, follow those .
  • Seek immediate medical care. Go to your employee health unit, emergency department, or personal doctor.

Once you are with medical professionals, they will assess the exposure. If you have a skin puncture or cut, you may also need a tetanus toxoid booster. The following are some questions a doctor may ask about the exposure.

Caring For An Hiv+ Family Member Or Friend

HIV cannot penetrate healthy skin. In order for it to enter the body, there must be a break in the skin. As a safeguard against contact with blood or body fluids, a person providing care for bleeding wounds should wear disposable gloves. This is a precautionary measure to ensure that the person is not exposed to the virus through tiny cuts in the hands that may be unnoticed.

The infected person should reserve a thermometer for personal use. It should be washed with warm soapy water after each use, soaked in rubbing alcohol for 10 minutes, dried and stored.

How Long Does Hiv Live Outside The Body


There are many myths and misconceptions about how long HIV lives and is infectious in the air or on a surface outside the body.

Unless the virus is kept under specific conditions, the true answer is not very long.

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.

How To Be Safe When Coming Into Contact With Infected Blood

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.

How Could You Get Hiv From Contact With Blood

  • 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.

When there is no soap or water available, one alternative is to use hand sanitizers or waterless hand scrubs. Some of these products are made of ethyl alcohol mixed with emollients and other agents. They are often available as a gel, or on wipes or towelettes. Alcohol-based hand sanitizers should contain at least 60% alcohol to be effective. Sanitizers do not eliminate all types of pathogens.

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

When soap and water was mixed with washings from a woman’s cervix and vagina and with seminal fluid , there was a 57% to 87% decrease in the number of viable peripheral blood mononuclear cells . “The present study demonstrates that soap and water solutions should be effective in inactivating HIV and HIV-infecting cells associated with barrier contraceptives or cells that are present in the vaginal canal,” the researchers conclude.
