Does Aids Come From Hiv

How To Be Safe When Coming Into Contact With Infected Blood

Origin of HIV, or Where Does HIV Come From?

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.

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.

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.

When To Contact A Doctor

Anyone who is showing symptoms of HIV should contact a doctor as soon as possible. This is especially important if the individual has recently had sexual contact with someone else or shared a needle with someone else.

HIV can remain asymptomatic for a long time. For this reason, anyone who has recently had unprotected sex and is concerned about exposure to HIV should contact a doctor as soon as they can, even if they do not have any symptoms. The same goes for anyone who has recently shared a needle.

It can be difficult to discuss the possibility of having HIV. However, without proper treatment, HIV can be life threatening. In these situations, it is very important for people to put their long-term health first and to discuss the matter with a doctor.

Can You Get Hiv From A Blood Transfusion

How and where does AIDS come from?

Receiving a blood transfusion or other products made from blood is safe in the UK as all blood products have been screened for infections such as HIV since 1985.

In countries that dont have strict checks on the safety of their blood supply, receiving contaminated blood can pass the virus on. This can also happen in countries that dont screen other blood products, organs or sperm.

Giving blood has never been a risk.

What Should I Do If I Need To Clean Up Blood

HIV does not usually survive long outside of the body, but contact with blood should be avoided.

Hepatitis C can survive in dried blood at room temperature for several weeks, and hepatitis B can survive in dried blood for around a week outside the body.

To clean up blood that has been spilled, wear rubber gloves and mop up the liquid using bleach and warm water . Use warm, soapy water to clean away blood spilled on someones body.

Put the waste, used gloves and bloodied clothes in a plastic bag, seal and throw away.

How Long Does It Take For Hiv To Progress To Aids

How long does it take for HIV to progress to AIDS? In all but a few rare cases, if left untreated, HIV will progress to a stage of infection called AIDS. This is when the immune defenses have been compromised, and the body is less able to defend itself against potentially life-threatening infections.

Who Should Be Tested For Hiv

The Centers for Disease Control and Prevention recommends all people between the ages of 13 and 64 get tested for HIV at least once as a part of routine health care. People at high risk of contracting HIV should be tested at least once a year. High risk groups include men who have sex with men, people who inject drugs, those who have sexually-transmitted infections, and those who have multiple sex partners. Several different types of tests are available to detect HIV. At-home tests are available that may provide results in as soon as 20 or 30 minutes. How soon should you get an HIV test after exposure? If you test negative for HIV but have recently engaged in high-risk behavior, get retested 3 months later because it can take that long for the body to make HIV antibodies.

Where Does Aids Come From

Where did Aids come from?

The first recognised cases of Aids occurred in America in the summer of 1981, and soon afterwards in Africa. In the beginning doctors did not know what caused this disease, and it was only in 1983 that scientists discovered that Aids is caused by a virus – now known as HIV-1.

There are two viruses associated with Aids, namely HIV-1 and HIV-2.

HIV-1 is associated with infection in most parts of Africa, America, Europe and the rest of the world, while HIV-2 occurs mostly in West-Africa. There are many subtypes of HIV-1 .

There are many theories about the origin of Aids, but the truth is that nobody really knows where Aids came from. The most widely accepted theory is that HIV crossed the species barrier from primates to humans at some time during the twentieth century.

HIV is related to a virus called SIV which is found in primates such as chimpanzees, Macaque and African green monkeys. The virus probably crossed from primates to humans when contaminated animal blood entered cuts on the hands of humans who were butchering SIV-infected animals for food.

While the initial spread of HIV was probably limited to isolated communities who had little contact with the outside world, various factors such as migration, improved transportation networks, socio-economic instability, multiple sexual partners, intravenous drug use and an exchange of blood products, ultimately caused the virus to spread all over the world.

You’re More Likely To Get Hiv If Your Partner Has Hiv And An Std

People with both HIV and an STD have more HIV in their semen or vaginal fluid. This makes it easier for a person with an STD or HIV to give the virus to others when having sex without a condom.

Remember, many people who have HIV don’t know it. It can take many years for symptoms to show up. That is why it is so important to use condoms during sex, or not to have sex at all.

When Did Hiv Enter The Population

By looking at the genome sequences of different viruses over time, researchers can calibrate a molecular clock based on the rate of sequence change, or mutations. Scientists can then use this to infer the rate of evolution and thus determine approximately when the most recent common ancestor existed.

Using this technique, researchers estimated that HIV-1 group M originated in 1908 and group O in 1920. HIV-2 groups A and B originated a bit later approximately in 1940 and 1945, respectively.

Unresolved Questions About Hiv Origins And Emergence

The discovery of the main HIV / SIV phylogenetic relationships permits explaining broad HIV biogeography: the early centres of the HIV-1 groups were in Central Africa, where the primate reservoirs of the related SIVcpz and SIVgor viruses exist similarly, the HIV-2 groups had their centres in West Africa, where sooty mangabeys, which harbour the related SIVsmm virus, exist. However, these relationships do not explain more detailed patterns of biogeography, such as why epidemic HIV-2 groups only evolved in the Ivory Coast, which is one of only six countries harbouring the sooty mangabey. It is also unclear why the SIVcpz endemic in the chimpanzee subspecies Pan troglodytes schweinfurthii did not spawn an epidemic HIV-1 strain to humans, while the Democratic Republic of Congo was the main centre of HIV-1 group M, a virus descended from SIVcpz strains of a subspecies that does not exist in this country. It is clear that the several HIV-1 and HIV-2 strains descend from SIVcpz, SIVgor, and SIVsmm viruses, and that bushmeat practice provides the most plausible cause of cross-species transfer to humans. However, some loose ends remain.

It is not yet explained why only four HIV groups spread considerably in human populations, despite bushmeat practices being widespread in Central and West Africa, and the resulting human SIV infections being common.

How To Delay The Progression Of Hiv To Aids

How AIDS originated ? Shocking proof

How does HIV turn into AIDS? Is it possible to delay the process? Yes. There is currently no cure for AIDS, but the condition can be delayed to give the person a longer period of good health. Each class of the medications works differently to control the virus. It is advisable to use a combination of three drugs from two classes.

  • Non-nucleoside reverse transcriptase inhibitors . This class includes drugs like efavirenz, etravirine and nevirapine. These drugs work by disabling a protein required by the HIV virus to reproduce.
  • Nucleoside or nucleotide reverse transcriptase inhibitors . This class of drugs includes abacavir. The drugs work by producing faulty protein that resemble those used by the HIV virus to reproduce.
  • Protease inhibitors . This class includes atazanavir, darunavir, fosamprenavir and indinavir. These drugs inhibit protease, a protein required by the HIV virus to reproduce.
  • Entry or fusion inhibitors. Entry inhibitors include enfuvirtide and maraviroc. These drugs delay the development of AIDS by inhibiting the entry of the HIV virus into the CD4 cells.
  • Integrase inhibitors. Integrase inhibitors include raltegravir, elvitegravir and dolutegravir. Integrase is a protein used by the HIV virus to insert its DNA into the CD4 cells. These drugs function by inhibiting it.

When to Start Drugs

All people with HIV should be on antiretroviral drugs. However, drugs are particularly necessary in these situations:

Are Women More Likely To Get Hiv

Yes. Biologically speaking, a woman is more vulnerable to heterosexual transmission of the disease because the genitalia are easily exposed to seminal fluids.

Gender inequality has great influence on the spread of HIV/AIDS among women. In some cultures, many women and girls are often put in situations where they engage in non-consensual sex or have sex for money.

In the U.S., minority communities have been hit the hardest by HIV. African American and Hispanic women together represent less than 25% of all U.S. women, yet they account for more than 78% of AIDS cases reported among women in the country.

Where Can I Go For Hiv Testing

You can get tested for HIV and other STDs at your doctors office, a community health clinic, the health department, or your local Planned Parenthood health center. You might want to get your HIV test at a place that also has HIV counseling .

You can either get an anonymous” or “confidential HIV test, depending on the laws in the state that you live in. Confidential” testing means your name is on the test, and the results go in your medical records. Your doctors and insurance company may also see the results. If you test positive, your results are sent to your local health department so they know the rates of HIV in your area. But your results are protected by privacy laws, so nobody else can see them without your permission.

“Anonymous” testing means your name isnt on the test. Youll get an ID number that youll use to find out your results. Your results wont go in your medical records, and they wont be sent to your insurance company or the health department youre the only one who will know them.

STD testing, including HIV testing, isnt usually automatically part of your regular checkup or gynecologist exam you have to ask for it directly. Be honest with your nurse or doctor so they can help you figure out what tests are best for you. Dont be embarrassed: your doctor is there to help, not to judge.

How Do I Avoid Getting Hiv During Sex

HIV is spread through contact with blood or sexual fluids , usually during vaginal and anal sex. So the only 100% certain way to avoid HIV is to not have vaginal or anal sex.

But most people do have sex at some point in their lives, so learning about HIV prevention and knowing how to have safer sex is important. Using condoms REALLY lowers your risk of getting HIV. If youre going to have sex, using condoms every single time is the best way to protect yourself from HIV. Theres also a daily pill you can take called PrEP that can help prevent HIV. Your doctor or nurse can tell you if PrEP is right for you.

Some sexual activities are safer than others when it comes to getting HIV. These activities are no risk theyve never caused a reported case of HIV:

  • masturbating

  • having oral sex with a condom or dental dam

  • using clean sex toys

These activities are lower risk theyve only caused a few reported cases of HIV :

  • “French or deep kissing

  • vaginal sex with a condom and/or PrEP

  • anal sex with a condom and/or PrEP

  • oral sex without a condom or dental dam

These activities are high risk millions of people get HIV this way:

  • vaginal sex without a condom or PrEP

  • anal sex without a condom or PrEP

Theres no vaccine that protects against HIV, but lots of people are working on making one. And there are medicines that can help prevent HIV.

Do I Have To Disclose That I Have Hiv

HIV AIDS Origin Of HIV Wh Does HIV Come From Monkey

In general, you should tell people who may be impacted by your HIV status about your illness. Your doctor should know to optimize your care. You may want to tell close friends and family about your condition. You may want to disclose that you have HIV to others who have it, such as those in a support group. Sex partners and people you share needles with need to know if you are HIV positive. They are at risk of contracting the virus from you. Some states have laws that make it a crime not to disclose your HIV-positive status to sex partners or needle-sharing partners before you have sex or inject drugs. Check HIV disclosure laws by state. Employers are not allowed to discriminate based on HIV status.

How Do You Get Hiv From Semen Or Vaginal Fluid

Body fluids including semen and vaginal secretions can contain HIV. If a person has HIV and a detectable viral load, HIV can passed on to someone if their semen or vaginal secretions get into the body of a sexual partner during vaginal or anal sex.

If a man has HIV and a detectable viral load, one of his body fluids where the virus is found is his semen.

If he has a detectable viral load and his semen gets into the body of his sexual partner during sex, then HIV can get into the other persons bloodstream.

Pre-cum also contains HIV this is why there is a risk of infection even if a man pulls out of his partner before he ejaculates.

If a woman has HIV and she has a detectable viral load, one of her body fluids where the virus is found is in her vaginal secretions.

If these come into contact with a penis during sex, then HIV could be transmitted. The virus in her secretions can enter through the delicate skin of the penis or foreskin.

How Can I Protect Myself

The best way to protect yourself from HIV is to not have sex and not share needles.

If you decide to have sex, reduce your risk of getting HIV by:

  • using a condom every time you have sex
  • getting tested for HIV and making sure all partners do too
  • reducing the number of sexual partners you have
  • getting tested and treated for STDs having an STD increases the risk of HIV infection

Understanding how HIV spreads can help you make safer choices about sex. Talk to your doctor if you have any questions about HIV and if you want to get tested.

Understanding Hiv And Aids

Generally speaking, the time it takes to go from HIV infection to AIDS is around five to 10 years if no medical intervention is made. Differences in time can be due to any number of factors, including:

  • The genetic strain of HIV a person living with the virus has been infected with
  • The general health of the individual
  • The place where the person lives
  • A person’s genetics or family history
  • Smoking and other personal lifestyle choices

This is, of course, if the person receives no treatment. The picture changes entirely if they do.

Since 1996, the introduction of antiretroviral drugs has dramatically altered the natural progression of HIV infection. While HIV still cannot be cured, people newly diagnosed with HIV who get treated and stay in care can be expected to have near-normal to normal life expectancies. As with other chronic diseases, early detection is key to identifying and treating the virus as soon as possible.
