How Is Hiv Transmitted Through Needles
HIV isnt transmitted only through sexual contact. Sharing needles also puts a person at higher risk of contracting HIV.
When a needle is injected into a persons body, it breaks the skin barrier. If the needle has already been injected into another person, it can carry traces of their blood, along with any infections they have. The contaminated needle can introduce these infections into the second persons body.
Researchers dont know if having an undetectable viral load reduces the risk of HIV transmission through shared needles, but its reasonable to assume it may provide some risk reduction.
HIV can affect anyone. Whatever their age, gender, sexuality, ethnicity, or race, everyone should take steps to protect themselves. But due to socioeconomic factors, some demographic groups have higher HIV transmission rates and generally are more affected by HIV.
According to the CDC , the general demographic traits most affected by HIV are:
Transgender women are also highly impacted by HIV transmissions as a population, reports the CDC .
These groups are disproportionately affected by HIV, but they arent inherently at greater risk of contracting HIV. An individuals personal risk depends on their behaviors, not on their age, gender, sexuality, ethnicity, race, or any other demographic factor.
After I Begin Hiv Treatment How Long Does It Take For The Risk Of Sexually Transmitting Hiv To Become Effectively Zero
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 Do You Bring This Up To A Potential Partner
Talking HIV status and sex with a potential partner can be intimidating, because you cant predict how someone will react.
Even if they have some knowledge of HIV and safer sex, they might still be worried about having sex with someone living with HIV.
Here are some things that might help make the convo easier:
- Pick a time and place to talk where you can take your time without being interrupted.
- Be prepared with information on HIV treatments and prevention methods, so you can answer questions and direct them to resources.
- Talk to them about U=U and the precautions you can take to protect their health during sex.
- Be open to hearing what they have to say, and give them time to process the information.
- Be prepared for the possibility that they may react negatively or not want to move forward, and try not to take it personally. Their reaction is all their own.
There are several precautions you and your partner can take to prevent contracting or transmitting HIV through sexual activity.

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.
Stay On Top Of Medications Including Art Prep And Pep
There are a few medications available that can help prevent the transmission of HIV:
- ART. A person living with HIV may take medication known as ART to help them stay healthy and prevent the transmission of HIV. Most people who take it as prescribed can lower their viral load to an undetectable level.
- PrEP. Short for pre-exposure prophylaxis, PrEP is a drug that someone who is HIV-negative can take to lower the risk of contracting HIV by as much as 99 percent .
- PEP.Post-exposure prophylaxis, or PEP, is a drug regimen that can help reduce the risk of HIV after a possible exposure when started within 72 hours.

How Do I Avoid Passing Hiv On To Someone Else
If you are infected with HIV, the best way to prevent spreading HIV infection to others is to:
- take your medication as prescribed there is a very low risk of passing on HIV if your own infection is under control
- use condoms and a water-based lubricant for anal and vaginal sex
- never share needles, syringes and other injecting equipment
If you have HIV infection, you are expected to notify anyone who is at risk of exposure from you:
- Tell people you have had sex or taken drugs with. Your doctor can help you decide who may be at risk and help you to contact them either personally or anonymously.
- Tell anyone you intend to have sex with about your HIV status . This is required by law in some states.
If you are pregnant, talk to your doctor about starting antiretroviral treatment to prevent the infection passing to the baby during pregnancy, childbirth or breastfeeding. Read more about HIV and pregnancy.
How Is Hiv Transmitted
The person-to-person spread of HIV is called HIV transmission. People can get or transmit HIV only through specific activities, such as through sex or injection drug use. HIV can be transmitted only in certain body fluids from a person who has HIV:
- Blood
- Vaginal fluids
- Breast milk
HIV transmission is only possible if these fluids come in contact with a mucous membrane or damaged tissue or are directly injected into the bloodstream . Mucous membranes are found inside the rectum, the vagina, the opening of the penis, and the mouth.
In the United States, HIV is spread mainly by:
- Having anal or vaginal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV
- Sharing injection drug equipment , such as needles, with someone who has HIV
HIV can also spread from a woman with HIV to her child during pregnancy, childbirth , or breastfeeding. This is called mother-to-child transmission of HIV.
You can’t get HIV from casual contact with a person who has HIV, such as a handshake, a hug, or a closed-mouth kiss. And you can’t get HIV from contact with objects such as toilet seats, doorknobs, or dishes used by a person who has HIV. Use the ClinicalInfo You Can Safely ShareWith Someone With HIV infographic to spread this message.

Does Being Durably Undetectable Mean That The Virus Has Left My Body
Even when viral load is undetectable, HIV is still present in the body. The virus lies dormant inside a small number of cells in the body called viral reservoirs. When therapy is halted by missing doses, taking a treatment holiday or stopping treatment, the virus emerges and begins to multiply, becoming detectable in the blood again. This newly reproducing virus is infectious. It is essential to take every pill every day as directed to achieve and maintain a durably undetectable status.
Contaminated Blood Transfusions And Organ/tissue Transplants
- receiving blood transfusions, blood products, or organ/tissue transplants that are contaminated with HIV. This risk is extremely small because most countries test blood products for HIV first.
If adequate safety practices are not in place, healthcare workers can also be at risk of HIV from cuts made by a needle or sharp object with infected blood on it. However, the risk of occupational exposure, is very low in most countries.
If you think you have been exposed to HIV, the only way to find out if you have HIV is to have an HIV test.

What is HIV?
Human immunodeficiency virus 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.
Theres an epidemic of HIV in the United States and around the world. According to the Centers for Disease Control and Prevention , more than 1.1 million people in the United States are living with HIV, and 1 in 7 of them arent aware of it. An estimated 39,782 people in the country were diagnosed with HIV in 2016 alone.
HIV transmission occurs in many different ways, including through condomless sex and by sharing needles. Risk of transmission varies depending on several factors including:
- sexual practices and the HIV status of sexual partners
- sharing needles for drug use or tattoos
- use of PrEP, PEP, condoms, or having an undetectable viral load
Its important to understand the risk level based on actual factors in preventing the transmission of HIV.
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.

How Can I Reduce My Risk Of Getting Hiv
- Get tested for HIV. Talk to your partner about HIV testing and get tested before you have sex. Use this testing locator from the Centers for Disease Control and Prevention to find an HIV testing location near you.
- Choose less risky sexual behaviors. HIV is mainly spread by having anal or vaginal sex without a condom or without taking medicines to prevent or treat HIV.
- Use condoms every time you have sex. Read this fact sheet from CDC on how to use condoms correctly.
- Limit your number of sexual partners. The more partners you have, the more likely you are to have a partner with poorly controlled HIV or to have a partner with a sexually transmitted disease . Both of these factors can increase the risk of HIV transmission.
- Get tested and treated for STDs. Insist that your partners get tested and treated, too. Having an STD can increase your risk of getting HIV or spreading it to others.
- Talk to your health care provider about pre-exposure prophylaxis . PrEP is an HIV prevention option for people who don’t have HIV but who are at risk of getting HIV. PrEP involves taking a specific HIV medicine every day to reduce the risk of getting HIV through sex or injection drug use. For more information, read the ClinicalInfo fact sheet on Pre-Exposure Prophylaxis .
- Don’t inject drugs. But if you do, use only sterile drug injection equipment and water and never share your equipment with others.
When Should I Get Tested For Hiv
If you think you could have HIV, talk to your doctor or sexual health clinic about having a test. Not all people who have HIV will experience a seroconversion illness, so testing is important if you think you might be at risk. Some people at high risk need to be tested regularly.
You should get tested for HIV if:
- you have had unprotected sex with a partner whose HIV status is unknown or who has HIV but does not have a measurable amount of virus in their blood
- you have had unprotected sex with a person from a country that has high rates of HIV infection
- your sexual partner has recently travelled to a country that has high rates of HIV infection and may have had unprotected sex there
- you have had unprotected sex with a sex worker in Africa, Eastern Europe, South East Asia or Papua New Guinea
- you have ever shared injecting equipment
Early diagnosis is important and can improve the long-term course of the illness.
It is a good idea to talk to your doctor or sexual health clinic about other STIs at the same time.
Your information will be kept confidential unless there are major concerns for your safety or the safety of others. HIV is a notifiable disease, which means laboratory staff need to inform the government about new cases, but this information is also confidential.

Why Do Some People With Hiv Infection Develop Aids
Over time, untreated HIV infection damages the immune system and makes it more difficult to fight infections and cancers.
Before there were effective treatments for HIV infection, all infected people went on to develop AIDS within about 10 years. Today, people with HIV who take effective treatment are unlikely to develop AIDS and will have a near-normal life expectancy. This is because these medicines keep the amount of virus in their blood under control and protect the immune system.
What About Blood Or Breast Milk
HIV is sometimes passed on from mother to child during pregnancy. It can also happen during birth or when breastfeeding. However, the risk of this can be reduced, providing that the mother has received a diagnosis. Pregnant women who take HIV medication can reduce the risk of infecting their child. They may also have a C-section instead of a natural birth. HIV medication is also given to babies for several weeks after birth. In countries where safe drinking water is accessible, formula milk is recommended.
There are also other ways HIV could be contracted through contact with positive blood. These include health workers accidentally being exposed to infected fluids and blood transfusions. However, both of these are very unlikely, especially in developed countries. There are some countries where the risk of infection from a blood transfusion is higher for example, some countries in Africa or the former Soviet Union.

Aids Or Hiv Life Expectancy Without Medication
How long can you live with HIV or AIDS if you chose not to treat with ART combinations or other prescription drugs? In the absence of such therapy, a patient should expect to see a notable decrease in life expectancy.
In countries where health care and ARTs arent readily accessible, HIV rates are above 20 percent. Shorter HIV life expectancy in these regions, combined with a high incidence of AIDS in younger age groups, boosts their overall mortality rate.
Population studies proved that AIDS patients who did not take HIV medications survived for roughly three years. Once they developed a dangerous opportunistic illness, life expectancy with AIDS decreased to one year or less.
Thats why HIV and AIDS remain a serious threat to public health, and why early detection is absolutely critical to long-term survival.
How Transmission May Occur
Tattoo artists create their designs by injecting ink into the second layer of a person’s skin, known as the dermis. They do this by using a tattoo machine which punctures the skin with a collection of small, high-speed needles. Body piercing, by contrast, uses a single needle to puncture the skin.
As a result of the broken skin, certain infections can theoretically be passed from one customer to the next if the gun or needles aren’t properly disinfected. But do they?

Whats The Difference Between Hiv And Aids
HIV is the virus that causes AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. HIV and AIDS are not the same thing. And people with HIV do not always have AIDS.
HIV is the virus thats passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system that helps protect you from infections. When you dont have enough of these CD4 cells, your body cant fight off infections the way it normally can.
AIDS is the disease caused by the damage that HIV does to your immune system. You have AIDS when you get dangerous infections or have a super low number of CD4 cells. AIDS is the most serious stage of HIV, and it leads to death over time.
Without treatment, it usually takes about 10 years for someone with HIV to develop AIDS. Treatment slows down the damage the virus causes and can help people stay healthy for several decades.
Effective Ways To Prevent Hiv/aids
The human immunodeficiency virus destroys immune cells which fight infection. This makes it difficult for your body to fight off infections and certain kinds of cancer. Without proper treatment, an HIV infection can progress to acquired immunodeficiency syndrome or AIDS, a stage where your immune system is seriously damaged and you get a number of severe illnesses known as opportunistic infections.1
HIV spreads through contact with body fluids like blood, semen, pre-seminal fluids, vaginal fluids, rectal fluids, or breast milk from an infected person. In the United States, this virus is mostly spread by having sex with or sharing syringes or other injection equipment with someone who is infected. It can also be transmitted from a mother to her child during the course of the pregnancy, while breastfeeding, or during childbirth.2 Although the number of people being infected with HIV has been declining, it still remains a cause of concern with thousands of new cases being diagnosed every year.3 But take heart, there are things you can do to protect yourself from this dangerous infection.
Here are some ways to keep yourself safe.
