Can You Get Hiv From Straight Sex

No 4 Having Vaginal Sex : 1 In 1250

Straight Talk about Sexually Transmitted Diseases – Leena Nathan, MD | UCLAMDChat

Most women who get HIV are infected through vaginal sex. In such cases, an HIV-positive man transmits the virus to his female partner through preseminal fluid or ejaculate, which allows HIV to pass through the linings of the vagina and cervix.

  • Reduce the risk. In theory, withdrawal practiced as a safety measure may help reduce a womans risk of contracting HIV from an HIV-positive partner, but because the virus can be found in preseminal fluids, the method may not be effective. Using condoms, however, can help lower the odds of transmitting HIV by 80 percent or more, according to the World Health Organization.

How To Have Safer Sex With Your Hiv

In recent years, several advances have made intimacy between a couple with one HIV-positive partner somewhat safer. People who are aggressively managing their HIV with medications called antiretroviral therapy, or ART, usually have lower levels of HIV in their blood and bodily fluids. This, Henderson explains, also decreases the chances that theyll transmit the virus to someone else. According to the CDC, people who maintain undetectable viral loads that is, the level of HIV in the blood is lower than can be detected with current technology have virtually no chance of infecting a sexual partner.

Individuals at high risk for contracting HIV can also take a combination of medicines called pre-exposure prophylaxis, or PrEP, which works to prevent the virus from establishing a permanent infection in the body, Henderson explains. PrEP involves taking an antiretroviral pill every day and seeing a healthcare provider every three months to take an HIV test and get a prescription refill.

Though its often given in an emergency room in urgent situations, post-exposure prophylaxis, or PEP, offers an option for people who have just participated in high-risk sex, such as having had anal intercourse with a man who is HIV positive. Henderson notes that PEP has to be taken within 72 hours of possible exposure to the virus.

Hiv Can Spread Through Sexual Contact Between Women

During the study, the team gave the couples condoms and taught them other ways to prevent passing along HIV to their partner. But in 137 couples, transmission did occur sometime during the decade. In these cases, the team compared the viruses of the newly infected person with those of the partner.

They found that HIV was most likely to be transmitted when its genetic code had a particular pattern. These versions of the HIV genes seem to make the virus good at initially infecting and replicating within a person.

Turned out, this pattern is the average DNA sequence that scientists find when they examine HIV strains in people from around the globe. “The average sequence in the population is probably average because it works best, and we found that that is true,” says Jonathan Carlson, a computational biologist at Microsoft Research, who contributed to the study.

To establish a long-term infection through sexual contact, an HIV virus must first infect a single cell on the genitals. Then the virus multiples and spreads to adjacent cells. “Fitter” viruses are more efficient at infecting new cells and then replicating themselves, Carlson says.

And the higher the initial barrier to this initial infection, the fitter the virus has to be to complete this process.

“What was most striking was that risk factors that were known to affect the risk of transmission affected the selection,” says Eric Hunter, a virologist at Emory University, who also contributed to the study.

Lets Look At Some More Cdc Data On Hiv Infection Rates Who Is At Risk

Straight women have higher rates of HIV than straight men.

That said, there is a group of straight people women who have extremely high HIV infection rates. You can scream racism all you want, but the statistics are what they are.

Black women have higher than average rates of sexually transmitted diseases.

The Center for Disease Control provides this data about STD infection rates among black women:

Straight men and women make up 90 percent of the population, but they account for only 15 percent of non-childhood AIDS cases. Only 6 percent of men with AIDS, the Centers for Disease Control and Prevention says, contracted the virus from straight sex. And even that figure doesnt hold up to a closer look. Several studies now suggest that most men who claim they got the virus this way are lying. They got it from sex with other men or sharing needles with addicts. Those studies also show that many women listed in the straight-sex category are either IV-drug users themselves or have likely contracted AIDS from sex with an IV drug user..

Dont be gay. Dont use illegal drugs. Dont have sex when you or she has an open wound or a herpes wound. Thats it. Youre safe from HIV.

If Someone Already Has Hiv And Subsequently Gets An Std Does That Put Their Sex Partner At An Increased Risk For Getting Hiv

I

If the person living with HIV gets and maintains an undetectable viral load by taking antiretroviral treatment, then an STD does not increase the risk of transmitting HIV.6 However, HIV-infected persons who are not taking antiretroviral treatment may be more likely to transmit HIV when they have another STD.

HIV-negative sex partners of people with HIV can prevent HIV if:

  • HIV-positive people use antiretroviral therapy as prescribed. ART reduces the amount of virus in blood and body fluids. People with HIV who take ART, as prescribed, to achieve and maintain an undetectable viral load can stay healthy for many years, and have effectively no risk of transmitting HIV to sexual partners.
  • Sex partners take PrEP medications, as prescribed, after discussing this option with their healthcare provider and determining whether it is appropriate.
  • Partners choose less risky sex activities.
  • Partners use a new condom for every act of vaginal, anal, and oral sex throughout the entire sex act .

What Are The Chances Of Getting Hiv Through Anal Or Vaginal Intercourse

One way to address the anxiety about infecting a partner is to understand the exact level of risk involved with different types of sexual activity. Among heterosexuals, vaginal intercourse is a common route of HIV transmission, with the woman at greater risk for HIV infection than the man. Says Henderson, The risk for infection for the female is about twice that of the male partner.

The type of sexual behavior that poses the greatest risk for passing on the HIV virus is receptive anal intercourse, Henderson says, explaining that the person receiving the penis in the anus is the receptive person. In heterosexual sex, that is the woman.

She notes that according to the Centers for Disease Control and Prevention , receptive anal intercourse carries a risk for HIV transmission 17 times greater than receptive vaginal intercourse. In men who have sex with men, anal intercourse also poses a risk of infection for the insertive partner, Henderson says, although the danger is 13 times greater for the receptive partner.

Keeping Your Guard Up Against Hiv

Today we have powerful anti-retroviral medicines that can ensure just about anybody can have a long productive life if they get infected with HIV.

And treatments like PrEP and PEP significantly reduce the chances of becoming infected if youre exposed to the virus.

Sometimes this gives people the idea that HIV is no big deal.

But HIV is a hassle. HIV-positive people have to take their meds every day. Theres still social stigma. The meds have side effects. You have to be careful about passing it to somebody else.

HIV is not something you want in your body. After all, it attacks your immune system, which you need to stay alive.

And thats why its so crucial to be aware of the ways HIV can infect you.

Unprotected Sex Std Risk

There is a significant likelihood of STD transmission from a single time of unprotected sex. As you can see, protection also does not completely take away the chances of contracting STD from one encounter. Abstinence is the only way to prevent the transmission completely. Nonetheless, you have a higher risk when you dont use protection, even just from one encounter.

Its best to assume that you have chances of STD transmission every time you have sex. Take precautions to prevent the spread by using protection every time. Also, you can greatly reduce the risk if you only have sexual contact with one other person, with both of you having been tested with negative results.

The only way to know for sure if youve picked up an STD from an unprotected sexual encounter is to get tested. If the person you were with told you they have a specific STD such as herpes or gonorrhea, it makes sense to get tested for that. But since youre not truly sure what STDs the person could have, you may want to do a complete STD test to be sure about your state of health. If you discover that you do have an STD, its nothing to be ashamed of. Its simply something that could impact your health in a negative way, especially if it goes untreated. Its important to find out if you have an STD so you can be treated.

Risk By Sexual Activity

How People Get HIV (Positively part 2 of 6)

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.

    HIV is sexist.

    A woman is twice as likely to catch the virus from an infected partner in a heterosexual relationship than a man is.

    And homosexual men are at even greater risk. They’re more than 20 times as likely to get infected from an HIV-positive partner than partners in a heterosexual relationship.

    Now scientists at Microsoft Research and the Zambia-Emory HIV Project have a clue about why these disparities exist.

    Only the strongest, most evolutionary “fit” versions of the virus tend to infect a man when he has sex with an HIV-positive woman, scientist report Thursday in the journal Science.

    Ways Hiv Can Be Transmitted

    How is HIV passed from one person to another?

    Most people who get HIV get it through anal or vaginal sex, or sharing needles, syringes, or other drug injection equipment . But there are powerful tools that can help prevent HIV transmission.

    Can I get HIV from anal sex?

    You can get HIV if you have anal sex with someone who has HIV without using protection .

    • Anal sex is the riskiest type of sex for getting or transmitting HIV.
    • Being the receptive partner is riskier for getting HIV than being the insertive partner .
    • The bottoms risk of getting HIV is very high because the rectums lining is thin and may allow HIV to enter the body during anal sex.
    • The top is also at risk because HIV can enter the body through the opening at the tip of the penis , the foreskin if the penis isnt circumcised, or small cuts, scratches, or open sores anywhere on the penis.

    Can I get HIV from vaginal sex?

    You can get HIV if you have vaginal sex with someone who has HIV without using protection .

    Can HIV be transmitted from a mother to her baby?

    HIV can be transmitted from a mother to her baby during pregnancy, birth, or breastfeeding. However, it is less common because of advances in HIV prevention and treatment.

    Can I get HIV from sharing needles, syringes, or other drug injection equipment?

    You are at high risk for getting HIV if you with someone who has HIV. Never share needles or other equipment to inject drugs, hormones, steroids, or silicone.

    Out Vs Hidden How Hiv Transmission Patterns Differ In Men Who Have Sex With Men

    Men who dont disclose same-sex sexual behaviour have different HIV transmission patterns compared to other men who have sex with men and heterosexual men.

    A recent UK study reveals that men who do not disclose same-sex sexual behaviour are more likely to have relations with men who also choose not to disclose their sexual behaviors. As such, these men are less likely to be in the close sexual networks that can accelerate HIV transmission known as HIV clusters.

    One explanation suggested for this by the study authors might be that non-disclosed MSM have fewer sexual partners than men who are open about having sex with men. They may also use condoms more consistently or have sex with lower-risk partners.

    In the study, researchers mapped the HIV transmission network using a phylogenetic analysis of 14,405 people living with HIV including 8,452 self-identified MSM, 1,341 self-identified heterosexual men and 1,743 self-identified heterosexual women.

    But among the men who identified as heterosexual, 249 were linked clusters of male-to-male sex, suggesting they had not disclosed same-sex behaviour to clinical staff.

    The findings also indicate that non-disclosed MSM are more likely to be black than men who are open about same sex behaviour. These results echo findings that black gay men in the UK are less likely to disclose their sexuality than white gay men.

    This echoes research from large USA cities on the role bisexually plays in HIV transmission.

    Although there were 508 new cases of HIV infections attributed to heterosexual contact, it is likely the case that those newly-infected men were not being honest. Men who engage in gay sexual contact or use IV drugs arent likely to admit it to a doctor.

    Has there ever been a single documented case of a straight male contracting HIV through heterosexual sex?

    We are taught that HIV affects everyone. That is a lie. HIV is a disease afflicting gay men and black women. Of course that doesnt mean no one should care about AIDs. But it does mean we should rationally assess our risk.

    Is HIV something we men need to worry about?

    Details magazine did an amazing expose on HIV that every man should read:

    Straight men and women make up 90 percent of the population, but they account for only 15 percent of non-childhood AIDS cases. Only 6 percent of men with AIDS, the Centers for Disease Control and Prevention says, contracted the virus from straight sex. And even that figure doesnt hold up to a closer look.

    Who Is At Greater Risk

    The transmission and acquisition of HIV from vaginal intercourse are high in cases of condom-less sex, both in women and men. While the risk tends to be higher among women due to biologic vulnerability , men are also at risk with everything from concurrent sexually transmitted diseases to circumcision status adding to that risk.

    How Does Hiv Attack The Human Body

    HIV cannot live on its own in the environment. So, in order to survive, the virus has to attack other living cells and use their metabolism to make copies of itself. Unfortunately, HIV attacks some of the human cells that are vital to a healthy immune system, including the white blood cells known as T-helper cells or CD4 cells. HIV also multiples within CD4 cells and because it continually keeps changing its outer coat it is resistant to being destroyed by white blood cells.

    What Cdc Is Doing

    CDC is pursuing a high-impact HIV prevention approach to maximize the effectiveness of current HIV prevention interventions and strategies. Funding state, territorial, and local health departments and community-based organizations to develop and implement tailored programs is CDCs largest investment in HIV prevention. This includes longstanding successful programs and new efforts funded through the Ending the HIV Epidemic in the U.S. initiative. In addition to funding health departments and CBOs, CDC is also strengthening the HIV prevention workforce and developing HIV communication resources for consumers and health care providers.
