How Can Hiv Be Contracted

Is It Hard To Take These Drugs

How is HIV Transmitted? Episode 2

The HIV medicines that currently are recommended are usually very simple and easy to take. Several drug combinations are available that package 3 separate medicines into only 1 pill, taken once a day, with minimal side effects.

For the great majority of people, HIV medicines are tolerable and effective, and let people with HIV live long and healthy lives. For some people, the drugs may be difficult to take every day, and for a small number, they cause serious side effects or don’t work well.

Once patients are on medications, they must work with their health care providers to find solutions for side effects and monitor how well the drugs are working.

The good news is that there are many excellent HIV medicines. Finding the right combination of medicines for each person is usually possible–a combination that controls the virus but does not cause side effects.

Hiv Treatment & Undetectable

Todays HIV treatments, called antiretroviral therapy or ART, are extremely effective. Some treatments are a single tablet. Long-acting injectable medications are likely to be approved and available soon. Medicine has come a long way since the first HIV treatment options became available in the 1990s.

There is still no functional cure for HIV, but ART can help people live long, healthy lives.;Todays medications are provided in combinations that reduce a persons viral load to levels so low its undetectable. People who become undetectable cannot transmit the virus to others.

Viral load is a term that describes how much virus a person living with HIV has in their body.

Without HIV medications, the virus replicates which causes the amount of virus in the body to increase.

HIV medications prevent HIV from making copies of itself. Then, the amount of HIV in the body goes down.

To see how well HIV treatments are working, doctors and other providers measure the amount of virus in the blood and report a measurement called your viral load. Its simply a measurement of how many copies of the virus are in a single unit of blood.

A very low amount of virus may even be undetectable by viral load tests . A common undetectable level is <20 copies per milliliter of blood. Low viral loads are those that are less than 200 copies per milliliter. Very high viral loads can be over 500,000 copies per milliliter.

Other Less Common Ways

Eating food thats been chewed by an HIV-infected person can cause the virus to be transmitted. This happens if infected blood has mixed with the food and has only been seen among infants.

Being bitten by an HIV-infected individual can also lead to an infection, but only if the skin has been broken. This has only been seen in cases where there was serious trauma, damage to tissue, and bleeding.

How Are The Drugs Taken

Most people who are getting treated for HIV take 3 or more drugs. This is called combination therapy or “the cocktail.” It also has a longer name: antiretroviral therapy or highly active antiretroviral therapy . Combination therapy is the most effective treatment for HIV.

People with HIV need to work closely with their providers to decide which drugs to take. Several coformulations are available, and for most patients, HIV treatment involves taking just 1 or 2 pills per day.

Ways Hiv Cannot Be Spread

Four curable sexually transmitted infections

HIV is not spread by:

  • Air or water
  • Mosquitoes, ticks or other insects
  • Saliva, tears, or sweat that is not mixed with the blood of a person with HIV
  • Shaking hands; hugging; sharing toilets; sharing dishes, silverware, or drinking glasses; or engaging in closed-mouth or social kissing with a person with HIV
  • Drinking fountains

How Is Hiv Spread From Person To Person

HIV can only be spread through specific activities. In the United States, the most common ways are:

  • Having vaginal or anal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV. Anal sex is riskier than vaginal sex.
  • Sharing injection drug equipment , such as needles, with someone who has HIV.

Less common ways are:

HIV is spread only in extremely rare cases by:

  • Having oral sex. But in general, the chance that an HIV-negative person will get HIV from oral sex with an HIV-positive partner is extremely low.

How Does Hiv Spread

HIV spreads when infected blood, semen or vaginal fluids enter the body. Because symptoms can be mild at first, people with HIV might not know they’re infected. They can spread HIV to others without knowing it.

HIV can spread:

  • during sex
  • through sharing needles for injecting drugs or tattooing

HIV also can pass from mother to child during pregnancy, childbirth, or breastfeeding.

HIV does not spread through:

  • pee, poop, spit, throw-up, or sweat
  • coughing or sneezing
  • sharing eating utensils or drinking glasses

Blood Transfusions & Transplants And Hiv

FAST FACTS

  • In most places in the world the risk of getting HIV from a blood transfusion is very low.
  • International health guidelines state that all blood products must be tested for viruses such as HIV, and in most countries rigorous testing procedures are put in place.
  • In rare cases where blood or blood products, such as a donated organ or tissue, have not been tested, HIV may be transmitted if the donation has come from an HIV-positive individual.
  • You have the right to ask your healthcare professional if a blood product has been tested for HIV or not.
  • You cannot get HIV from donating blood as new, sterile and disposable needles are used.

What Happens If I Stop Taking Antiretroviral Therapy

What is HIV? | How is HIV Transmitted?

When therapy is stopped, viral load rebounds, and the risk of transmitting HIV to a sexual partner in the absence of other prevention methods returns. NIAID-supported research has provided clear-cut scientific evidence to support the benefits of staying on continuous antiretroviral treatment. In 2006, NIAIDs large clinical trial called SMART showed that people receiving intermittent antiretroviral treatment had twice the rate of disease progression compared to those receiving continuous treatment.;

Taking antiretroviral treatment daily as directed to achieve and maintain durably undetectable status stops HIV infection from progressing, helping people living with HIV stay healthy and live longer, while offering the benefit of preventing sexual transmission. Stopping and re-starting treatment can cause drug resistance to develop, making that treatment regimen ineffective and limiting future treatment options.

Don’t Miss: Where Does Hiv Originated From

How Hiv Infects The Body

HIV infects;the immune system,;causing progressive damage and eventually making it unable to fight off infections.

The virus attaches itself to immune system cells;called CD4 lymphocyte cells, which protect the body against various bacteria, viruses and other germs.

Once attached, it enters the CD4 cells and uses it;to make thousands of copies of itself. These copies then leave the CD4 cells, killing them in the process.

This process continues until eventually the number of CD4 cells, also called your;CD4 count, drops so low that your immune system stops working.

This process may take up to 10 years, during which time you’ll feel and appear well.;

Direct Contact With Blood

HIV is also known to spread through the use of syringes, needles, or any other equipment thats used to prepare and inject drugs when theyre shared with an HIV-positive person. Depending on temperature and other factors, the HIV virus can live in a needle for up to 42 days.5 Tattooing or body piercing, which breaks the skin, can also be risky if needles are shared.

There is effectively no risk of sexual transmission of HIV when the partner living with HIV has achieved an undetectable viral load and then maintained it for at least six months. Most people living with HIV who start taking antiretroviral therapy daily as prescribed achieve an undetectable viral load within one to six months after beginning treatment.

A persons viral load is considered durably undetectable when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load. It is essential to take every pill every day to maintain durably undetectable status.

How Is Hiv/aids Transmitted

HIV vs. AIDS: Differences and connections

Sexual contact – HIV is spread most commonly by sexual contact with an infected partner. The virus enters the body through the lining of the vagina, vulva, penis, rectum, or mouth during sexual activity.

Blood contamination – HIV may also be spread through contact with infected blood. However, due to the screening of blood for evidence of HIV infection, the risk of acquiring HIV from blood transfusions is extremely low.

Needles – HIV is frequently spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa through accidental sticks with contaminated needles or other medical instruments, is rare.

Mother-infant – HIV also can be spread to babies born to, or breastfed by, mothers infected with the virus.

Blood Transfusions And Transplants

In the early days of the HIV epidemic in the 1980s to early 1990s, there were many people infected with HIV due to tainted blood transfusions. Prior to 1992, there were no screening tools available to ensure that the U.S. blood supply, including clotting factors and plasma, was free of the virus.

That risk has fallen dramatically in recent decades due to advances in detection technologies and the universal screening of blood and tissue donations in the United States and other countries. This not only includes the screening of HIV but other bloodborne infections like hepatitis B and hepatitis C.

Today, the risk of HIV from a blood transfusion in the United States is roughly one in 1.5 million. From 2002 to 2008, only one documented case of HIV transmission from a transfusion was reported by the Centers for Disease Control and Prevention .

The risk outside of the United States can vary dramatically. In Egypt, for instance, one in four HIV infections is the result of a transfusion. By contrast, in South Africa, the country with the highest HIV incidence in the world, the transmission risk is closer to one of every 76,000 transfusions.

Hiv: How Its Not Transmitted

The following are nine ways the virus is not spread:

Kissing and touching. Social kissing and hugging pose no risk of transmission, Sha says. Also, being sexual with someone without exchanging infected body fluids does not spread the virus. The only time deep kissing is a risk is when the person infected with HIV has open sores or oral bleeding, Sha notes.

Sharing a living space. Any casual contact with someone who has HIV, including sharing a bathroom, is safe. However, Sha tells patients not to share razor blades or toothbrushes. If someone who is infected nicks himself while shaving or has bleeding gums, it could increase risk of transmission.

Sharing food or utensils. The virus cannot survive on surfaces, so sharing utensils and other household items will not spread HIV. You can even share a meal with someone who is infected without worry. Transmission has been associated with mothers pre-chewing food for their babies, when infected blood from the mouth mixes with the food. Known as pre-mastication, it is a common practice in Africa, but not typically done in the United States, Sha says.

Saliva, sweat, or tears. An infected persons saliva, sweat, and tears do not put you at risk.

Water fountains. Sipping from a water fountain after someone who has HIV used it is considered casual contact and will not lead to transmission.

Mosquitoes and other insects. The virus is not viable in insects or ticks, Sha says.

How Long Can Hiv Survive Outside The Body

Once outside the body, HIV usually cant survive for very long. Coming into contact with blood or semen that has been outside the body doesnt generally pose a risk for HIV transmission.

Similarly, the risk of passing on HIV to someone else if you have a detectable viral load and cut yourself is also very low. Wash away any blood with soap and hot water and cover the wound with a sticking plaster or dressing.

How Could You Get Hiv From Contact With Blood

How to Test for HIV?

The risk of HIV transmission through blood comes when the person has a detectable viral load;and their blood enters another persons body or comes into contact with a mucous membrane. These are parts of the body with wet, absorbent skin such as the:

  • eyes
  • inside of the anus
  • mouth.

Theres also a risk if blood from a person who has a detectable viral load comes into contact with a cut or broken skin, giving HIV a way through the skin and into someones bloodstream. If blood gets onto skin that isnt broken, there is no risk.

In a medical setting, its possible for HIV to be transmitted by someone accidentally cutting themselves with a blade or needle they have used to treat a person living with HIV.;

This is called a needlestick injury. The risk of being infected in this way is very low. However, if someone thinks they have been exposed to HIV through a needlestick injury, post-exposure prophylaxis may be an option.

What Is Usually The First Sign Of Hiv

The initial presentation of an HIV infection is a flu-like illness which includes:

  • Rash
  • Swollen lymph nodes: Lymph nodes are a part of the bodys immune system that helps get rid of bacteria and viruses. An HIV infection, like many other infections, can cause the inflammation of lymph nodes, which can be felt as round or nodular swellings in the armpit, groin, and neck. The swelling is often associated with aches and pains in these areas.

How Is Hiv Spread Through Sex

You can get infected from sexual contact with someone who has HIV. Sexual contact that can transmit HIV includes:

  • vaginal sex
  • anal sex
  • oral sex

If you have sex, the best thing you can do to prevent HIV infection is practice “safer sex” with any partner who is not proven to be HIV negative . To do so, always use protection–this could include using a condom, dental dam, or other latex barrier, and/or PrEP . It is also important to avoid “rough sex” or other activities that might cause bleeding. If you use lube with a condom, make sure it is water-based, not oil-based. Oil-based lube causes latex condoms to break. See more tips for using condoms; note that, if used correctly and consistently, condoms also protect against other sexually transmitted infections and against pregnancy.

If you have unprotected sex with someone who is infected, it doesn’t mean that you will be infected, too. But there is always a chance, especially if your partner is not on effective HIV medicines. Using condoms and PrEP reduces your risk.

HIV is NOT spread by:

  • hugging or massage
  • sex toys you don’t share
  • daily living with someone who has HIV

Frequently Asked Questions About Hiv/aids

HIV can be detected in several fluids and tissue of a person living with HIV. It is important to understand however, that finding a small amount of HIV in a body fluid or tissue does not mean that HIV is transmitted by that body fluid or tissue. Only specific fluids from an HIV-infected person can transmit HIV. These specific fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the blood-stream for transmission to possibly occur.

In the United States, HIV is most commonly transmitted through specific sexual behaviors or sharing needles with an infected person. It is less common for HIV to be transmitted through oral sex or for an HIV-infected woman to pass the virus to her baby before or during childbirth or after birth through breastfeeding or by prechewing food for her infant. In the United States, it is also possible to acquire HIV through exposure to infected blood, transfusions of infected blood, blood products, or organ transplantation, though this risk is extremely remote due to rigorous testing of the U.S. blood supply and donated organs.

For more information, see:;How safe is the blood supply in the United States?

For more information on latex condoms, see “Male Latex Condoms and Sexually Transmitted Diseases.”

In women, the lining of the vagina can sometimes tear and possibly allow HIV to enter the body. HIV can also be directly absorbed through the mucous membranes that line the vagina and cervix.

What Does It Mean To Be Durably Undetectable

How is HIV transmitted? Facts, risk factors, and prevention

Taking antiretroviral therapy daily as prescribed to suppress HIV levels leads to an undetectable status. A person is considered to have a durably undetectable viral load if their viral load remains undetectable for at least six months after their first undetectable test result. It is essential to continue to take every pill every day as directed to maintain an undetectable viral load.
