How is HIV Transmitted?

Human Immunodeficiency Virus (HIV) is a virus that targets the immune system, and its transmission primarily occurs through specific activities. Understanding these transmission methods is crucial for effective prevention and management of the virus within the UK and beyond.

Transmission Through Sexual Contact

The most common way HIV is transmitted is through unprotected sexual intercourse with a person who has the virus. This includes vaginal, anal, and, to a lesser extent, oral sex. During these activities, the virus can enter the body through the mucous membranes of the genitals, rectum, or mouth. The risk of transmission increases if there are cuts or sores, which may allow the virus to enter the bloodstream more easily.

Transmission Through Blood

Sharing needles or syringes that contain HIV-infected blood is a highly efficient way for the virus to spread. This mode of transmission is particularly associated with intravenous drug use. In the UK, needle exchange programs aim to reduce this risk by providing clean equipment to drug users.

Additionally, although rare in the UK due to strict screening processes, HIV can be transmitted through blood transfusions, organ transplants, or tissue donations from an infected donor. The NHS employs rigorous testing to virtually eliminate this risk, ensuring that blood products are safe.

Mother-to-Child Transmission

Mothers with HIV can pass the virus to their child during pregnancy, childbirth, or breastfeeding. However, with modern antiretroviral treatments and medical interventions, the risk of mother-to-child transmission can be significantly reduced. In the UK, pregnant women are routinely offered an HIV test to facilitate early diagnosis and treatment, which dramatically reduces transmission risks.

Myths and Misunderstandings

It is important to dispel common myths about how HIV is transmitted. The virus cannot be spread through casual contact, such as hugging, kissing, sharing food or drinks, using the same toilet, or via insect bites. HIV requires the exchange of certain body fluids, such as blood, semen, vaginal fluids, rectal fluids, or breast milk, from a person with HIV.

Prevention Strategies

Prevention strategies in the UK focus on education, safe sex practices, and the use of preventive medications like pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP). Condom use during sexual intercourse remains one of the most effective ways to prevent the transmission of HIV.

Regular testing and early treatment are also essential measures. People who are aware of their HIV-positive status can take antiretroviral therapy (ART) to reduce their viral load to undetectable levels, greatly reducing the risk of transmitting the virus to others.

How Can You Get HIV?

HIV is a virus that can make the body sick by hurting the immune system. You can catch the virus in certain ways. It's important to know how people can get HIV so we can stop it from spreading.

Getting HIV From Sexual Contact

The most common way to get HIV is by having sex without a condom with someone who has the virus. This includes vaginal sex, anal sex, and sometimes oral sex. HIV can get into your body through soft parts inside your genitals, bottom, or mouth. If you have cuts or sores, the virus can get into your blood more easily.

Getting HIV From Blood

People can get HIV by sharing needles that have infected blood on them. This often happens with people who use drugs with needles. In the UK, there are programs to give clean needles to help stop this from happening.

It's very rare, but HIV can also be passed through blood transfusions, organ transplants, or tissue donations from someone who has the virus. Doctors in the UK test blood and organs very carefully to make sure they are safe.

Passing HIV From Mother to Baby

Mothers with HIV can give the virus to their baby during pregnancy, when the baby is being born, or through breastfeeding. But there are medicines that can help mothers so they do not pass HIV to their babies. In the UK, pregnant women are offered an HIV test to help keep their babies safe.

Things That Do Not Spread HIV

It's important to know that HIV is not spread through hugging, kissing, sharing food or drinks, using the same toilet, or insect bites. HIV only spreads through certain body fluids like blood, semen, vaginal fluids, rectal fluids, or breast milk, and only from a person who has HIV.

How to Prevent HIV

In the UK, people learn about safe sex and can use medicines to help prevent HIV, like PrEP and PEP. Using a condom during sex is one of the best ways to stop HIV.

Getting tested and treated early is also very important. People who know they have HIV can take medicine to make the virus really low in their blood. This helps stop them from giving the virus to other people.

If you want to learn more, you can use helpful tools like videos or talk to a doctor or nurse.

You cannot get HIV from saliva. This means you won't get HIV from kissing.

But be careful if both people have big cuts or sores in their mouths. If there is blood, there is a small risk.

Can you get HIV from oral sex?

Oral sex means using your mouth on someone's private parts. You might worry if you can get HIV this way.

It's important to be safe. Use protective things like condoms or dental dams to lower the risk.

Talk to a doctor or nurse if you have questions. They can help you understand and stay safe.

Oral sex is safer than anal or vaginal sex if you want to avoid HIV. But there is still a small chance of getting HIV, especially if you have cuts or sores in your mouth.

Can you get HIV from a blood donation?

HIV is a virus. It can make people sick.

You can get HIV if you have blood from someone who has it.

But, hospitals check blood carefully. They make sure it is safe.

Ask a doctor or nurse if you have questions. They can help.

In countries where blood is carefully checked, the risk is very small. But HIV can still be passed on if the blood is not safe.

Do condoms stop HIV completely?

Using a condom can help protect from HIV, but it does not stop all risk. Condoms work well when used the right way. They can stop HIV from spreading most of the time.

It's good to use condoms every time you have sex. Ask an adult you trust if you have questions.

Pictures or videos can help explain how to use condoms. Talk to a doctor or nurse if you want to learn more.

Using condoms the right way every time helps keep you safe from HIV. But no method can stop it completely.

Can a baby get HIV from breastfeeding?

Yes, a baby can get HIV from breastfeeding if the mother has HIV. HIV is a virus that can make people sick. If a mother has HIV, the virus can be in her breast milk.

Here are some tools to help families:

  • Talk to a doctor or nurse for advice.
  • Use medicine if the doctor gives it to the mother.
  • Consider other ways to feed the baby, like formula milk.

Always ask questions if you are unsure.

Yes, a mom with HIV can pass it to her baby when breastfeeding.

Can you get HIV from sharing needles?

Yes, sharing needles is not safe. You can get HIV this way. Use a new needle each time to stay safe.

Be careful! Using the same needles or syringes as someone who has HIV can easily spread the virus to you.

Can you get HIV from food made by someone with HIV?

No, you cannot get HIV from eating food.

Even if someone with HIV makes your food, it's still safe to eat.

HIV does not live in food. It cannot spread this way.

Using tools like text-to-speech software can help if reading is hard.

No, you cannot catch HIV from cooking or eating food.

Can a mom with HIV give it to her baby?

Yes, but with the right help, the chance of the mother passing it to the baby during pregnancy, birth, or breastfeeding can be made much smaller.

How does medicine help stop the spread of HIV?

Medicine for HIV is called antiretroviral therapy (or ART). ART helps people with HIV live longer and healthier. It also makes it hard for the virus to spread to other people.

If someone takes ART medicine every day, it lowers the amount of virus in their body. This makes it very hard for the virus to spread.

To help understand these ideas, you can:

  • Use pictures or videos about ART and HIV.
  • Ask a doctor or nurse if you have questions.
  • Find easy-to-read books about ART and HIV.

Medicine called antiretroviral therapy can make the amount of virus in a person's body so low that doctors can't find it. This means the virus can't be passed to someone else during sex.

Can you get HIV from getting a tattoo or piercing?

Getting a tattoo or piercing is safe if clean tools are used. It is important to make sure the tools are clean to avoid getting germs or viruses.

HIV is a virus. You cannot get HIV if the tools are clean and safe.

To stay safe, only go to places where they use new needles each time.

Ask the person giving you a tattoo or piercing if they use clean tools.

If you feel unsure, take someone you trust with you to ask questions.

Getting HIV from tattoos or body piercings is not likely if things are kept clean and safe.

Can you get HIV from a cut?

You can get HIV from cuts or wounds, but it almost never happens. This is because the cut needs to touch blood that has the HIV virus in it for someone to get infected.

Can you get HIV from animals?

No, you cannot get HIV from animals. Only people can give HIV to other people.

If you need help understanding this, you can:

  • Ask someone you trust to explain it to you.
  • Use apps or websites that make reading easier.

No, people cannot get HIV from animals. HIV is a virus that only affects humans.

Can you get HIV from spit?

HIV is a virus that makes people very sick. You cannot get HIV from someone's spit (saliva).

It is safe to hug, kiss, or talk to someone with HIV. HIV spreads when blood or other body fluids mix, not through spit.

If you want to learn more about HIV, you can ask a doctor, nurse, or use helpful websites.

No, spit (saliva) does not spread HIV. The virus spreads through certain body fluids like blood, sperm, vaginal fluids, and breast milk.

Can you get a shot to stop HIV?

No, there is no shot right now that stops HIV. But scientists are working hard on it.

Here are some ways to stay safe from HIV:

  • Use a condom when you have sex.
  • Take medicine called PrEP if your doctor says it's right for you.
  • Do not share needles.

If you need help or have questions, you can talk to a doctor or nurse.

Right now, there is no shot to stop people from getting HIV. Scientists are working hard to make one.

How does PrEP help stop the spread of HIV?

PrEP is a medicine. People take it to stop getting HIV.

Here’s how it works:

  • It makes it hard for the HIV virus to stay in your body.
  • You need to take it before you come into contact with the virus.
  • PrEP works best if you take it every day.

Talking with a doctor or nurse can help. They can explain PrEP and how to use it.

Some people might use reminders to take their medicine every day. A calendar, alarm, or app can help with this.

PrEP is a medicine you take every day. It helps stop people from getting HIV. This is important for people who might get HIV easily.

Do other infections make it easier to get HIV?

Yes, if you have another STI, it is easier to get or give someone HIV.
