What Are The Odds Of Getting Hiv

Can Hiv Be Transmitted Through Blood Transfusions

What Are the Chances of Getting an STD from One Unprotected Encounter?

Yes but this is very rare. In the unlikely event that a person who is HIV-positive donates blood products that are not tested, the person who receives the blood product is likely to develop an HIV infection too.

If youre thinking about donating blood but are not sure about your HIV status, you can request an HIV test in advance of donating at your local clinic.

In order to prevent this, international health regulations require all blood products, such as organs or tissues, to be screened for a number of viral or bacterial contaminations before they are used.

During the screening process any blood products which contain HIV, hepatitis B, hepatitis C, or syphilis will be disposed of.

This means that the transmission of HIV through blood products is very rare, but examples have occurred in some low-income countries which lack the equipment to test all blood.

Multiple Vulnerabilities Increase Risk In Men And Women

Vaginal sex is one of the primary ways a person can become infected with HIV. According to the U.S. Department of Health & Human Services, it accounts for about 6,300 new infections among women each year in the U.S. and about 2,800 new infections among heterosexual men.

Globally, the figures are even more dismaying. While the sexual transmission of HIV in the U.S. is highest among gay and bisexual men , heterosexuals are by far the group most affected worldwide.

This is especially true in Africa where most new infections are among heterosexuals. In these populations, vaginal sex is the predominant route of infection.

How Do I Get Tested For Hiv

A small blood sample, mouth swab, or urine sample is used to test people for HIV. It can take as long as three to six months after initial exposure for the signs of the virus to show up in your blood, and years before you show any symptoms.

You can be tested at a doctor’s office, hospital, community health center, or other health clinic. Some places have mobile testing vans. AIDS services organizations also may provide testing. At-home testing kits are also available.

Depending on where you go, testing may be free. You may be able to choose to take the test without giving your name. Many providers or groups that offer HIV testing also provide counseling.

If you choose to take a test at home, make sure to use a test that has been approved by the U.S. Food and Drug Administration . If the test has not been approved by the FDA, it may not give accurate results. Home tests are sold at drugstores and online. Follow up with your doctor to confirm the results of at-home tests and, if necessary, begin treatment.

Hiv And Stds Are Spread In The Same Ways

World AIDS Day: It

You can get HIV or an STD by having sex without a condom with a person who is already infected. HIV and some STDs can be passed from a mother to her baby while she is pregnant, during birth or through breast feeding. HIV and some STDs can also be spread by sharing drug “works” with someone who has HIV or an STD.

What Puts You At Risk For Stds And Hiv

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.

Risk By Sexual Activity

When discussing HIV risk, people often try to ascertain which “type” of sex is riskier vaginal, anal, or oral. From a purely statistical standpoint, anal sex is considered the highest risk activity with an almost 18-fold greater risk of infection compared to vaginal sex.

But this assessment is somewhat misleading, at least from an individual perspective. While vaginal sex may pose a lower risk comparatively, the figures neither take into account the way in which the disease is distributed between men and women nor the vulnerabilities which place some individuals at extremely high risk of infection.

Women are three to four times more likely to get HIV from men than the other way around. A young woman is more likely to get HIV from her first sexual encounter than her male partner.

There are some men who are far more likely to get HIV than others. Studies have shown, for example, that uncircumcised men are more than twice as likely to get HIV after vaginal sex than circumcised men.

Vulnerabilities vary by individual, so assessing the real risk of vaginal sex requires a better understanding of the factors that place some women and men at greater risk than others.

How Is Hiv Transmitted

Anyone, at any age, can get HIV. People usually acquire HIV from unprotected sex with someone living with HIV, through contact with HIV-infected blood, or by sharing needles with a person living with HIV. You may be at risk if:

  • You had sex without a latex or polyurethane condom. The virus passes from the person living with HIV to his or her partner via blood, semen, or vaginal fluid. During sex, HIV can get into your body through body fluids and any opening, such as a tear or cut in the lining of the vagina, vulva, penis, rectum, or rarely the mouth. Latex condoms can help prevent HIV transmission between sexual partners.
  • You or your sexual partners have shared needles with a person living with HIV. People who inject illegal drugs are not the only people who might share needles. For example, people with diabetes who inject insulin or draw blood to test glucose levels could also share needles. Talk to your partner about their drug and sexual history, and always use a new, sterile needle for injections.
  • You had a blood transfusion or operation in a developing country at any time.
  • You had a blood transfusion in the United States between 1978 and 1985.
  • You were diagnosed with or treated for hepatitis or tuberculosis at any time.

Giving And Receiving Oral Sex

New Gel to Stop Women’s Chances of Getting HIV

Though semen and pre-cum are not the only routes for contracting HIV, they are two avenues. Ejaculating during oral sex increases the risk. If you or your partner feels ready to ejaculate, you can remove your mouth to avoid exposure.

Barrier methods like latex or polyurethane condoms and dental dams can be used during every oral sex act. Change condoms or dental dams if you move from the vagina or penis to the anus, or vice versa.

Also use lubricants to prevent friction and tearing. Any holes in the barrier methods can increase exposure risk.

Abstain from oral sex if you have any cuts, abrasions, or sores in your mouth. Any opening in the skin is an avenue for possible viral exposure.

Be careful not to cut or tear your partners skin with your teeth during oral sex. This opening can expose you to blood.

The insertive partner is less likely than the receptive partner to get the infection from an HIV-positive partner. However, bodily fluids carrying the virus can enter the insertive persons body through the urethra or any cuts or sores on the penis.

  • Reduce the risk. If the insertive partner uses a condom, that can cut the risk of HIV transmission by an average of 63 percent, according to the CDC. You can help lessen the chance that the condom will slip or break by using water- or silicone-based lubricants. In addition, be aware that condoms dont fully protect against certain sexually transmitted diseases that can be contracted through skin-to-skin contact, like syphilis and herpes.

Other Types Of Hiv Risks

Another less-common way HIV is transmitted in the United States is needlestick injury. This typically happens when a health care worker is accidentally jabbed by a used needle or syringe that contains HIV-positive blood. Again, this is very rare.

Thirty years ago, blood transfusions and organ donations were an especially dangerous way that some people acquired HIV. Nowadays, donated blood and organs are routinely tested.

How Does Hiv Get Inside The Body In The First Place

It turns out that its relatively difficult for HIV to get inside the body and lock on to those white blood cells. This can only happen during intimate contact between two peopleby which we mean anal sex, vaginal sex, or sharing injection-drug equipment.

HIV cannot pass through a persons skin. This means that you will not become positive by touching bodily fluid that contains HIV, unless you have an open wound where youre touching the fluid. Even if you ingest the viruslets say, by eating food with traces of HIV inside itthe acid inside your stomach will protect you.

HIV almost always enters the body in one of three ways:

  • Direct contact with the bloodstream, either through an open wound or with a needle.
  • Direct contact with certain mucous membranesspecifically, the soft, permeable tissues inside the rectum, vagina, penis, and mouth.For newborns, exposure is possible during pregnancy, delivery, or shortly after birth by consuming breast milk from an HIV-positive person.

For adults, its important to remember that HIV can only enter the body when its exposed to an open wound, injected directly into the bloodstream, or passed through a mucous membrane, typically through anal or vaginal sex.

In addition, anyone who is pregnant should get an HIV test. If the results come back positive, your doctor can help you stay healthy and prevent your baby from getting HIV.

About 6 percent of the HIV diagnoses in 2015 can be attributed to the use of injection drugs, according to the Centers for Disease Control and Prevention . The reason is that needles, syringes, and other equipment can contain blood, and therefore HIV, which can then be directly transmitted into the bloodstream. Under the right environmental circumstances, the virus can survive in a used needle for up to 42 days, according to the U.S. Department of Health and Human Services. In addition, using drugs can lower peoples inhibitions, making them less likely to use a condom during sex or to take preventive HIV medications, further increasing their risk.

    • Reduce the risk. Although the number of HIV diagnoses among people who inject drugs has declined by 48 percent from 2008 to 2014, according to the CDC, experts worry that the rising opioid epidemic is putting new people at risk for getting the virus. To find substance abuse help, call the Substance Abuse and Mental Health Services Administrations national helpline at 1-800-662-HELP or visit its website, findtreatment.samhsa.gov, for a list of treatment facilities near you.
    • Reduce the risk. People who inject drugs can help lower their risk of exposure to HIV by using a sterile needle and syringe for each injection sterile needles can be obtained without a prescription at pharmacies and through syringe services programs at state or local health departments.

Risks To Insertive And Receptive Partners

There is a widespread belief among gay men that the insertive partner is at very low risk of HIV infection. It is true that HIV infection occurs less frequently in men who solely take the insertive role than in men who engage in both roles, or men who practise receptive anal intercourse only .

However, being the insertive partner in condomless sex remains a high-risk activity. The per-act risk for the insertive partner in anal sex is comparable to the per-act risk for the male partner in vaginal sex.

The receptive partner is at risk of infection from HIV in the semen and pre-seminal fluids of the infected partner. Rectal tissue is delicate and easily damaged, which can give the virus direct access to the bloodstream. However, such tissue damage is not necessary for infection to occur: the rectal tissue itself is rich in cells which are directly susceptible to infection.

The insertive partner is also at risk of infection, as there are high levels of HIV in rectal secretions, as well as blood from the rectal tissues . This creates a risk of transmission to the insertive partner through the tissue in the urethra and on the head of the penis particularly underneath the foreskin.

Several systematic reviews of studies have calculated that condomless receptive anal intercourse posed approximately ten to twelve times greater risk of infection than insertive anal intercourse.

What is HIV?

Human immunodeficiency virus attacks and weakens the immune system, making an individual more vulnerable to serious illness. Untreated HIV can lead to AIDS, which occurs when the immune system is so weak it becomes susceptible to serious infections and some cancers.

Theres an epidemic of HIV in the United States and around the world. According to the Centers for Disease Control and Prevention , more than 1.1 million people in the United States are living with HIV, and 1 in 7 of them arent aware of it. An estimated 39,782 people in the country were diagnosed with HIV in 2016 alone.

HIV transmission occurs in many different ways, including through condomless sex and by sharing needles. Risk of transmission varies depending on several factors including:

  • sexual practices and the HIV status of sexual partners
  • sharing needles for drug use or tattoos
  • use of PrEP, PEP, condoms, or having an undetectable viral load

Its important to understand the risk level based on actual factors in preventing the transmission of HIV.

Risk Factors In Women

The risk of HIV from unprotected vaginal sex is higher among women for a number of reasons. From a physiological standpoint, the tissues of the vagina are far more susceptible to HIV than those of the penis.

HIV is able to pass through these tissues when the immune system recognizes the invading virus and send defensive cells to “grab and drag” them through the lining to be destroyed.

Instead, HIV turns the table and attacks the very cells meant to help neutralize them. By doing so, the body helps facilitate its own infection. And, because the surface area of the vaginal epithelium is far greater than that of the male urethra, the opportunity for infection is increased, often exponentially.

Other physiological vulnerabilities include:

While the daily use of an HIV drug called pre-exposure prophylaxis can dramatically decrease the risk of HIV in an uninfected partner, there is evidence that works less well in women. Research published in 2016 suggests the level of the active drug molecule in vaginal tissue isn’t near as high as in rectal tissue.

None of this, of course, takes into account any of the social vulnerabilities that can place women at increased risk. These include sexual violence in relationships which not only steals a woman’s chance for self-protection but can result in damage to delicate vaginal tissue.

People Think Its Easy To Contract Hiv Thats A Good Thing Right Maybe Not Guest Post By Jason Kerwin

Daily Antiretroviral Drug Lowers Risk of Getting AIDS

    This is the fourteenth in our series of posts by students on the job market this year.People are afraid of HIV. Moreover, people around the world are convinced that the virus is easier to get than it actually is. The median person thinks that if you have unprotected sex with an HIV-positive person a single time, you will get HIV for sure. The truth is that its not nearly that easy to get HIV the medical literature estimates that the transmission rate is actually about 0.1% per sex act, or 10% per year.

    Great stuff! I’ve wanted to see precisely this paper for a while. I think it’s morally opprobrious that we exaggerate the risks to people, and it’s very interesting to also see that this backfires through the previously only theorized fatalism channel.

    I was 12 when magic Johnson came out that he wasHIV positive. I am now 37 and sex still scares me and I can honestly say I barely get any enjoyment out of it. This was helpful I’ll relax a little bit more

    my partner of six years is HIV positive,this has affected our sexual relationship and we do not have any child yet,because of his condition.he has been on hiv drug all this while and the VL shows 0.1%,can we make love without me contacting the virus?
