Effective antiretroviral therapy also prevents the transmission of HIV. When a person living with HIV is taking effective antiretroviral therapy and has a suppressed viral load HIV can no longer be transmitted through sex. Antiretroviral medicines should only be taken as prescribed by a health-care professional.
How likely are you to get HIV once?
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 it's 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.

Can you get HIV only once?
In other words, there may be a relatively small chance of acquiring HIV when engaging in a risk behavior with an infected partner only once; but, if repeated many times, the overall likelihood of becoming infected after repeated exposures is actually much higher.
Is HIV a risk behavior?
HIV Risk Behaviors. The risk of getting HIV varies widely depending on the type of exposure or behavior (such as sharing needles or having sex without a condom). Some exposures to HIV carry a much higher risk of transmission than other exposures.
How does HIV affect a person's chances of contracting it?
Certain behaviors can increase a person’s chance of contracting HIV. HIV transmits through bodily fluids, such as blood, semen, and breast milk. A person who has anal, vaginal, or oral sex with a person that has detectable levels of HIV has a less than 2%. Trusted Source.
How many people have HIV in 2019?
HIV is a global health issue that affected an estimated 38 million people worldwide in 2019. People have higher or lower chances of contracting HIV due to certain sexual behaviors and other factors.

When a person takes it daily, PrEP can reduce the risk of acquiring HIV through sex by 99%. Trusted Source.
How many children are under 15?
1.8 million were children under the age of 15
What is the risk of HIV transmission?
A key factor determining the risk of transmission is the amount of virus in body fluids, which is known as viral load. When a person is living with HIV and is on effective treatment, the amount of HIV in their body fluids falls drastically, to a level that is described as ‘undetectable’ viral load.
What are the factors that increase the risk of sexual transmission?
Another factor that would increase the risk of sexual transmission is the HIV-negative person having an STI (genital ulcer disease). This is thought to more than double the chances of acquiring HIV ( relative risk 2.65 ). The risk can be lowered by prevention measures.
Is per exposure risky?
The per-exposure measure of risk may cause activities to seem less risky. You might be surprised at the apparently low figures that constitute 'high risk' activities. Being told that there is, for example, a one in 200 chance of infection could, conceivably, lead someone to think, “Only one in 200. Well, that’s not too bad”.
Is a viral load biologically verified?
Some figures are from carefully managed clinical trials, whereas others are from real-world conditions. Some facts can be biologically verified (such as an undetectable viral load) where as others rely on how people report their behaviour to researchers (such as condom use).

What is HIV? Human immunodeficiency virus (HIV) 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.
Why is it important to reduce viral load?
Reducing the viral load helps a person with HIV stay healthy, and it also lowers the risk of that person transmitting HIV to a sexual partner. When their viral load is reduced to such a low level that blood test can’t detect it (undetectable viral load), that person won’t be able to transmit HIV to a partner.
What is the cell that helps HIV?
Second, when a person has an infection, their immune system sends out certain cells to help fight it. These cells are called CD4+ cells. They’re the same cells that HIV targets.
What are the cells that are most susceptible to HIV?
These cells are called CD4+ cell s. They’re the same cells that HIV targets. When their immune system is actively fighting off another infection, they may be more susceptible to HIV. If a partner has HIV with a detectable viral load and is also has another STI, the risk of HIV transmission increases.
Which partner is more likely to get HIV?
The receptive (or “bottom”) partner is 13 times more likely to be infected with HIV than the insertive partner, according to the CDC. That’s because the virus — found in blood, semen, preseminal fluid (“pre-cum”), and rectal fluids — can more easily enter the receptive person’s body through the thin lining of the rectum.
How many instances of exposure to HIV?
It takes only one instance of exposure to become infected with the human immunodeficiency virus, or HIV.

What does it mean if you have a 1 in 70 chance of getting HIV?
Case in point: Having a 1 in 70 chance of transmitting HIV does not mean it takes 70 exposures to the virus in order to seroconvert. It simply means that out of 70 exposures, on average, one will lead to HIV; bad luck might have it that the transmission occurs on the very first exposure.
What happens when you underestimate HIV?
During sex, our risk perception is replaced by love, lust, trust and intimacy. When you lack information or misunderstand facts, you can’t grasp your true HIV risk. If you underestimate the HIV prevalence in your community, you’ll underestimate your risk.
