Contaminated Blood Transfusions And Organ/tissue Transplants

Some Ways You Can Contract HIV and Their Risks

If adequate safety practices are not in place, healthcare workers can also be at risk of HIV from cuts made by a needle or sharp object with infected blood on it. However, the risk of occupational exposure, is very low in most countries.

If you think you have been exposed to HIV, the only way to find out if you have HIV is to have an HIV test.

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.

Ambulance Workers

Dental Workers

Embalmers

Embalming the bodies of persons with a HIV infection presents a risk because HIV can live for hours in a deceased body.

Chances Of Getting Hiv From One Encounter

by Dr. Sanjiv Khanse | Diseases and Conditions

You have unprotected sex with someone from the opposite sex, just that once.

You realize later that the person is HIV positive, meaning that he/she is infected with the HIV .

You want to know what are the odds of you getting infected from exposure with that single unprotected encounter.

You could also have a blood transfusion once or share an injection needle with an infected partner just that once. What are the chances of contracting this viral disease?

The odds vary and depend on a few factors.

How Hard Is It To Contract Hiv From

Many people have questions about scenarios they have heard could lead to HIV transmission. For example, a lot of people are told at some point that you can get HIV from using a toilet seat. In reality, the likelihood of that happening is so minuscule, it isnt worth considering. For HIV to be transmitted in that manner, two people who both had open wounds that made contact with the toilet seat would have to use the same seat seconds after each other. Even then, the chances of infection would still be small. A slightly more realistic way that people worry about contracting HIV is through kissing. However, its still only a tiny bit more realistic. A person would again have to have open sores in their mouth, and it would take a lot of saliva to transmit the virus.

Most people are unlikely to have to worry about how hard is it to contract HIV during their day-to-day lives. You wont accidentally contract it from sharing a glass with someone. You wont get it from touching someone in a non-sexual manner, unless you both have open wounds. Before believing anything you hear about how hard is it to contract HIV, its always best to research. You can quickly dispel some common myths by Googling them.

What Puts You At Risk For Stds And Hiv

World AIDS Day: Top 5 Myths about HIV/AIDS

You’re at risk if you:

  • Have sex without using a condom, with someone who is infected.
  • Have had an STD.
  • Have more than one sex partner.
  • Are under the influence of drugs and alcohol.
  • Many women have STDs without having symptoms. This means that unless she gets tested, she may have an STD and not know it.
  • Young women are getting HIV or an STD because the tissue lining the vagina is more fragile.

If you are a woman, take charge of your sexual health. Be sure to schedule pelvic exams and pap smears every year. Get tested and learn how to protect yourself from STDs and HIV.

Hiv Risk From A Single Blood Transfusion

Because of careful donor selection criteria, HIV risk from a single blood transfusion has very much reduced due to strict screening measures.

HIV seroprevalence in blood donors is less than 2 percent of the adult American population because of strict screening measures.

Despite this, HIV transmission may still occur due to three reasons:

Blood may be collected during the window period of infection, when the donor is infectious but has not yet developed positive result on the HIV laboratory tests.

Infection with variant strains of HIV that may not be detected by regular screening tests.

However, according to CDC,

the risk of HIV transmission by transfusion was low, even before screening, and has been virtually eliminated by the routine screening of donated blood and plasma.

But, in case HIV positive blood is given to an HIV negative individual, the risk of HIV infection with a single transfusion exceeds that of any other risk. More than ninety percent of recipients transfused with HIV positive blood are found to be infected with the virus.

Is It True That Gay Men Are More At Risk For Hiv Than Other People

Although anyone can be at risk for HIV, some people can be more at risk depending upon the types of sexual practices and drug use they are engaging in. Being gay does not necessarily mean you are at higher risk, but certain activities gay men sometimes participate in might put them at greater risk. Overall, the gay male population in Canada has higher rates of HIV infection than some other populations. Stigma and homophobia can affect a person’s ability to access information about safer sex specifically for gay men.

Whats The Short Answer

Yes, its possible to get HIV from putting the tip in. And that can be from putting the tip of a penis into the butt, vagina, or mouth.

The risk of getting HIV from the tip varies between the body parts and other factors, like whether youre the one giving or receiving said tip, if one or both parties are taking HIV meds, and more.

Lets break down some common scenarios to help you gauge your risk.

Other Types Of Transmission

How I contracted HIV

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.

How Is Hiv Transmitted

HIV is transmitted between humans through the exchange of certain types of bodily fluids. Bodily fluids that can transmit HIV include blood, semen, breast milk, and vaginal fluids .

Not all body fluids can transmit HIV. The following cannot transmit HIV:

  • Exchanging saliva, like through closed-mouth kissing or sharing drinks/utensils
  • Coming in contact with an HIV positive personâs tears, sneezes, or sweat
  • Ordinary physical contact, such as hugging, hand shaking, or touching shared objects like cutlery, cups, or toilet seats .
  • Air or water
  • Pets and insects cannot carry the virus and infect you, because transmission of HIV is only between humans .

While care needs to be taken in some situationsâlike when having sex or when open injuries are presentâthis certainly does not mean that it is unsafe to be around people with HIV. Think of how you interact with the vast majority of peopleâbodily fluids are not exchanged. Harboring discriminatory thoughts only perpetuates a fearful stigma against someone with HIV, which only hurts the person who has it.

HIV is often transmitted through sexual activity and drug use in adults in the United States . Maternal transmissionâfrom mother to childâis how the infection is spread to infants .

Men Who Have Sex With Men

Gay or bisexual MSM are the most severely affected population. MSM account for just a small fraction of the total U.S. population, yet nearly two-thirds of all new infections occurred within this group in 2009, and one-half of all people living with HIV in 2008 were MSM. MSM within ethnic minority populations are at greatest risk .

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.

Hiv Treatment As Prevention

The Myths And Facts Of HIV And AIDS

People with HIV can take ART to lower their chance of transmitting HIV to others.

ART reduces the quantity of HIV in the body, or viral load, and keeps it at a low level.

The term viral load refers to the number of HIV copies per milliliter of blood.

Healthcare professionals define successful viral suppression as having a viral load of less than of HIV per milliliter of blood. Achieving and maintaining viral suppression significantly reduces the risk of HIV transmission.

Other ways to prevent HIV transmission include:

  • using a condom or other barrier method during sex
  • reducing the number of sexual partners
  • getting vaccinated against other STIs, such as HPV and hepatitis B
  • avoiding using injectable drugs, if possible
  • if using injectable drugs, avoiding sharing needles and syringes
  • following all workplace safety protocols

People can speak with a doctor to learn more about their individual risk of contracting HIV.

Anyone concerned about HIV exposure should contact a healthcare professional or a local emergency room to get testedand receive PEP.

Symptoms Of Hiv/aids And Stages

Many people donât have symptoms at first, and sometimes even for years or decades. But there are signs that can happen, such as flu-like symptoms soon after you become infected with HIV. Even if you donât feel sick, HIV damages the immune system. It hijacks infection-fighting white blood cells called CD4 cells and uses them to churn out thousands of copies of itself. Without treatment, HIV destroys so many of these cells that your body canât protect you from life-threatening infections. If your CD4 count drops below 200, you have AIDS.

There are three stages of HIV infection:

Stage 1: This the earliest stage. You may also hear it called the âacuteâ stage. You might have a fever, rash, fatigue, chills, and other flu-like symptoms. But you might not have any symptoms. If you do, they may start 2-4 weeks after youâre infected. During this time, the virus quickly makes many copies of itself.

Stage 2: During this stage, HIV continues to reproduce, and it slowly damages your immune system over time. You might not feel sick or have symptoms. But HIV isnât gone, and you can still spread it to other people. This stage can last for years or even decades.

Stage 3: This is when you have AIDS. Your immune system has been severely damaged, leaving you vulnerable to other illnesses. With AIDS, many people have symptoms such as chills, fever, sweats, swollen lymph glands, weakness, and weight loss.

Sex Toys Fingering Fisting And Hiv

Sex toys, such as dildos, come into direct contact with rectal/vaginal fluids and mucous membranes. This means sharing an uncleaned dildo or other toy can pass on HIV. Using sex toys on your own has no risk.

There is no direct risk of HIV from fingering or fisting , but be aware of being rough. Damage to anal/vaginal tissues, especially if there is any bleeding, will increase risk of HIV transmission if you then have anal, vaginal or oral sex later.

Hiv Diagnosis And ‘window Period’

You wonât know if you have HIV right after youâre infected. It takes time for your body to make antibodies and for antigens to show up.

The âwindow periodâ is the time between when you might have been exposed to HIV and a test can tell for sure you have it. This varies from person to person and test to test. Your testing counselor can tell you more about the window period for the test youâre taking. Here are some general guidelines:

An antibody test can detect HIV 23 to 90 days after youâre exposed to the virus. The window for a test that uses blood from a vein is faster than one that uses oral fluid or blood from a finger stick.

An antigen/antibody test done in a lab on blood from a vein can detect HIV infection within 18 to 45 days. It takes longer if the testâs done with blood from a finger stick.

A nucleic acid test usually has the shortest window: 10 to 33 days. This test is not generally used to diagnose HIV infection unless you have symptoms and a history that suggest you were infected only a few days ago.

If you have a negative test and werenât exposed to the virus during the window period for that test, you can be certain you didnât have HIV when you were tested.

The CDC recommends that all adults have an HIV test at least once, even if theyâre not at risk. If your risk is higher — for example, you have multiple sex partners or use needles for drugs — you should be tested every year.

How Can You Reduce Your Risk Of Contracting Hiv

How long can one live with HIV without treatment | hiv/aids

Ultimately, you shouldnt try to gauge your own risk of contracting HIV. The best thing to do is to assume that you always have a chance of contracting it when engaging in risky behavior. When it comes to sex, the best way to prevent HIV infection is to always use a condom. Not only should you use them every time, but you should use them properly, too. This may seem simple, but there are some important rules to follow. For example, no one should use a condom that has been in their wallet for the last year. Its important to use condoms as instructed and handle them with care. Taking one out of its packet with long fingernails isnt a good idea. You might also choose to use internal condoms, dental dams or gloves for protection.

There are other risks to manage, aside from having sex. Anyone who injects drugs should be sure to use clean equipment and never share with anyone else. Seeking out needle programs and other services makes this easier to do. Although it is an unlikely method of transmission, people in health care professions should be careful. They should ensure they have adequate training and knowledge. Health and safety in the workplace should involve methods for managing sharps and fluids.

Male Vs Female Partners

When having vaginal sex without a condom with a partner who has a penis, the vaginal membranes are more likely to tear than the partners penis.

In condomless anal sex with a partner who has a penis, the rectal membranes are also more likely to tear than the partners penis. Microscopic tears create an easier path for HIV and other STIs to enter the body when exposed.

Its possible for a partner with a penis to contract HIV during vaginal and anal sex. If a female partner is living with HIV with a detectable viral load, it can be carried in her vaginal secretions. If her partner has open sores on their mouth or penis, they can create a gateway for vaginal secretions or other bodily fluids with HIV to enter the body.

Uncircumcised men are at higher risk of contracting HIV from condomless sex than circumcised men. The delicate membranes of foreskin can tear during sex, creating a pathway for HIV to enter the body.
