What Is The ‘four

How do you get HIV?

In 1983, the Centers for Disease Control in the United States listed the main at-risk groups, including partners of people with AIDS, people who inject drugs, haemophiliacs and people who have recently been to Haiti. At the time that cases of AIDS began to emerge in the USA, the absence of definitive information about HIV and its link to AIDS, inflated the panic and stigma surrounding the epidemic. Before long people began to talk colloquially of a 4-H Club at risk of AIDS: homosexuals, haemophiliacs, heroin addicts and Haitians, contributing to further stigmatisation.21

I Am Hiv Positive How Can I Prevent Passing Hiv To Others

Take HIV medicines daily. Treatment with HIV medicines helps people with HIV live longer, healthier lives. ART can’t cure HIV, but it can reduce the amount of HIV in the body . One of the main goals of ART is to reduce a person’s viral load to an undetectable level. An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. People with HIV who maintain an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.

Here are some other steps you can take to prevent HIV transmission:

  • Use condoms correctly every time you have sex.
  • Talk to your partner about taking PrEP.
  • If you inject drugs, don’t share your needles, syringes, or other drug equipment with your partner.

Lowering The Risk Of Sexual Transmission

There are several protective measures which dramatically reduce the risk of HIV transmission during sex. You can find out more about these on other pages.

pre-exposure prophylaxis

Antiretroviral drugs used by a person who does not have HIV to be taken before possible exposure to HIV in order to reduce the risk of acquiring HIV infection. PrEP may either be taken daily or according to an event based or on demand regimen.;

Undetectable viral load: when people with HIV take effective treatment,;the amount of HIV in their body fluids falls drastically, to the point where they cannot pass HIV on to their sexual partners. An extremely low level of HIV in body fluids is referred to as an;undetectable viral load. The knowledge that this prevents transmission is often referred to ‘Undetectable equals Untransmittable’ .

PrEP: if the HIV-negative person takes antiretroviral medications as;pre-exposure prophylaxis ,;this significantly reduces the risk of acquiring HIV. The most common form of PrEP is in a tablet, but it can also be provided as a vaginal ring or an injection.

Condoms: if;male condoms or female condoms;are used, this significantly reduces the risk of acquiring HIV.

Male circumcision: if you are circumcised, this partially lowers your risk of acquiring HIV during vaginal sex.

Myths about HIV and AIDS

While research suggests that high concentrations of HIV can sometimes be detected in precum, it is difficult to judge whether HIV is present in sufficient quantities for infection to occur. To guard against the possibility of infection with HIV or any other STI it is best to practice safer sex by using condoms.

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.

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 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.

How Does A Person Get Hiv

How is HIV Transmitted? Episode 2

HIV can only be passed by these five body fluids:

  • blood
  • vaginal fluid
  • breast milk

HIV can be passed when one of these fluids from a person with HIV gets into the bloodstream of another personthrough broken skin, the opening of the penis or the wet linings of the body, such as the vagina, rectum or foreskin. HIV cannot be passed through healthy, unbroken skin.

The two main ways that HIV can be passed are:

  • through sex
  • by sharing needles or other equipment to inject drugs

HIV can also be passed:

  • to a fetus or baby during pregnancy, birth or breastfeeding

HIV cannot be passed by:

  • shaking hands, working or eating with someone who has HIV
  • hugs or kisses
  • swimming pools, toilet seats or water fountains
  • insects or animals

Since November 1985, all blood products in Canada are checked for HIV, to ensure that it is safe to get a blood transfusion. And there is no chance of getting HIV from donating blood.

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:

  • oral sex

Lets break each of these down in more detail.

When And Where Did Hiv Start In Humans

Studies of some of the earliest known samples of HIV provide clues about when it first appeared in humans and how it evolved. The first verified case of HIV is from a blood sample taken in 1959 from a man living in what is now Kinshasa in the Democratic Republic of Congo. The sample was retrospectively analysed and HIV detected. There are numerous earlier cases where patterns of deaths from common opportunistic infections, now known to be AIDS-defining, suggest that HIV was the cause, but this is the earliest incident where a blood sample can verify infection.9

Do Condoms Stop Hiv Being Passed On

Yes.Using a condom correctly prevents contact with semen or vaginal secretions , stopping HIV from being passed on. The virus cannot pass through the latex of the condom.

Condoms should only be used with a water-based lubricant;as oil-based lube weakens them.

People with HIV who are on effective treatment and have an undetectable viral load cannot pass on HIV through any of their body fluids.

Its also important to remember that if you have sex without a condom other sexually transmitted infections ;can be passed on.

Sex without a condom can also result in pregnancy if other contraception is not being used.

Ways That Hiv Is Not Transmitted

Pin on Health and Medication

HIV is not transmitted by day-to-day activities or by contact with objects, food or clothes.

The following list includes just a few examples of questions we get from people worried about catching HIV.

Most of these questions come from a combination of fear and ignorance. They come from a lack of confidence in understanding HIV transmission.

You can NOT catch HIV from:

  • Eating any food, cooked or uncooked, with blood on it.
  • From a sterile needle at a clinic or other health centre.
  • From a human bite.
  • From an insect bite including a mosquito bite.
  • From an animal.
  • From living in the same house as someone who is HIV positive.
  • From a sewing needle if you stab your finger.
  • From blood on a bus seat that went through your underwear.
  • Cleaning nail clippers.
  • Using a knife/fork/spoon/cup/plate that an HIV positive person may have used.
  • Getting sexual fluid on skin.
  • Getting sexual fluid on a cut that has already healed over. A cut has to be open to be a risk of HIV.

The above are all real examples sent as questions to i-Base. They show that ignorance about HIV is still common.;

Bites That Break The Skin

A bite that opens the skin and causes bleeding can lead to the transmission of HIV. However, according to the

goes up with increasing viral load.

Viral load is highest both during the early phase of HIV and without treatment with antiretroviral medications. Taking antiretroviral medications every day can reduce a persons viral load to very low levels that cant be detected through testing.

In this way, antiretroviral medications arent only a treatment, but an important tool for prevention. When HIV cant be detected in the blood, a person living with HIV cant sexually transmit the virus to a partner without HIV.

This principle is called Undetectable = Untransmittable and has been supported by

up to 6 months of taking antiretroviral medications each day to achieve an undetectable viral load.

A persons viral load is said to be durably undetectable when all test results are undetectable for at least 6 months after the first undetectable result.

Theres no need to be afraid of having casual contact with someone who is living with HIV. The virus doesnt live on the skin and cant live very long outside of the body.

Additionally, bodily fluids like saliva, tears, and sweat dont transmit HIV either.

Therefore, casual contact, such as holding hands, hugging, or sitting next to someone who has HIV, wont transmit the virus. Closed-mouth kissing isnt a threat either.

These include:

  • syphilis
  • gonorrhea
  • herpes

Can I Become Infected If My Partner Has Hiv

A partnership where one person is infected with HIV and the other is not can be described as a sero-discordant relationship. There is a risk of HIV transmission if the discordant couple has unprotected sex. However, this risk can be greatly reduced with the use of condoms during vaginal, anal and oral sex. Both partners in a discordant sexual relationship should take on the responsibility of protecting one another from HIV infection.

How Do You Get Or Transmit Hiv

You can only get HIV by coming into direct contact with certain body fluids from a person with HIV who has a detectable viral load. These fluids are:

  • Blood
  • Semen and pre-seminal fluid
  • Rectal fluids
  • Vaginal fluids
  • Breast milk

For transmission to occur, the HIV in these fluids must get into the bloodstream of an HIV-negative person through a mucous membrane ; open cuts or sores; or by direct injection.

People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners.

HIV Transmission Probability: How is HIV Transmitted (Crazy Facts)

HIV is not spread by:

  • Air or water
  • Mosquitoes, ticks or other insects
  • Saliva, tears, or sweat that is not mixed with the blood of a person with HIV
  • Shaking hands; hugging; sharing toilets; sharing dishes, silverware, or drinking glasses; or engaging in closed-mouth or social kissing with a person with HIV
  • Drinking fountains

How Is Hiv/aids Transmitted

Sexual contact – HIV is spread most commonly by sexual contact with an infected partner. The virus enters the body through the lining of the vagina, vulva, penis, rectum, or mouth during sexual activity.

Blood contamination – HIV may also be spread through contact with infected blood. However, due to the screening of blood for evidence of HIV infection, the risk of acquiring HIV from blood transfusions is extremely low.

Needles – HIV is frequently spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa through accidental sticks with contaminated needles or other medical instruments, is rare.

Mother-infant – HIV also can be spread to babies born to, or breastfed by, mothers infected with the virus.

Factors That Increase The Risk Of Sexual Transmission

Not every act of unprotected sex with an HIV-positive person results in HIV transmission. But other factors can make HIV transmission more likely.

If the HIV-negative person has an untreated sexually transmitted infection , the risk is greater.

Just as HIV treatment and an undetectable viral load prevents HIV transmission, a;high;viral load makes it more likely. Viral load refers to the quantity of HIV in a persons body fluids. It is extremely high in the first few weeks after a person is first infected with HIV. It may also be high if a person does not take HIV treatment and has advanced disease. People who have HIV without realising it cannot take HIV treatment, so there is a strong possibility that they have a high viral load. ;

Is Hiv And Aids An Occupational Concern

HIV Resources & FAQ

Where ever there is the possibility of contact with blood in the workplace, workers should take precautions to prevent contact with the skin, eyes or mucous membranes .

Routine Practices are recommended to prevent the spread of HIV in the workplace. Routine practices are based on the principle that all blood, body fluids, secretions, and excretions except sweat, non-intact skin, and mucous membranes, unless they contain visible blood, may contain transmissible infectious agents. Steps involve using protective clothing such as gloves, gowns or aprons, masks and protective eye wear when dealing with people’s blood and other blood-contaminated body fluids such as semen and vaginal secretions. They also do not apply to saliva except in dentistry where saliva is likely to be contaminated with blood.

Hand washing after contact with blood, blood-contaminated body fluids and soiled items is also recommended to reduce the risk of infection.

The best approach to most diseases is to prevent their occurrence – occupationally-related diseases are no exception. In the case of HIV, prevention is the only cure.

Other Types Of Transmission

In the past, HIV was spread by transfusion with blood products, such as whole blood or the “factor” used by hemophiliacs. Many people acquired HIV this way. The blood supply is now much more strictly tested and controlled in most countries. The odds of acquiring HIV from receiving blood or blood factor in countries like the US, the UK, and Canada are extremely low. For example, statistics from the US show that a person is more likely to be killed by a lightning strike than they are to acquire HIV from a blood transfusion. However, not every country screens all blood donations for HIV.

It is also possible to get HIV from skin grafts or transplanted organs taken from people living with HIV. Again, the risk is considered very low, as these “body products” must be strictly tested in the same way as blood products. Semen donations collected by sperm banks for artificial insemination are also considered “bodily products” and rigorously tested in high-resource countries. Private semen samples that are not processed by sperm banks or similar organizations may not have been tested. It is important for anyone receiving a private donor’s sperm for artificial insemination to have the donor tested for HIV.

If you are getting breast milk from a milk bank, it is important to ask if the bank tests the milk for HIV. Also, if your baby is getting breast milk from a wet nurse, it is important to make sure that she tests negative for HIV before giving her milk to your baby.
