How Is Hiv Diagnosed
Diagnosis of HIV infection during infancy depends on the detection of the virus. Since all infants born to HIV-infected mothers have a positive antibody test at birth because of the passive transfer of the HIV antibody across the placenta, virological testing is used to confirm the diagnosis.
For infants born to HIV-infected mothers, viral diagnostic testing is usually performed within the first 2 days of life, at 1 to 2 months of age, and at 4 to 6 months of age. A diagnosis of HIV infection can be made with two positive virologic tests obtained from different blood samples.
For children over 18 months, adolescents, or adults, diagnosis is made by testing the blood for the presence of HIV antibody.
Can Hiv Pass From Mothers To Their Babies
Infection can pass from pregnant women living with HIV to their babies in the womb and during birth. Taking HIV medications during pregnancy and childbirth dramatically lowers the risk of a baby becoming infected with HIV.
After birth, transmission can occur through breast milk. The highest risk may be in the early months after birth. It is recommended that new mothers who are living with HIV formula-feed their babies rather than breast-feed.
If you are a woman living with HIV and you intend to become pregnant, or you find out that you have during your pregnancy, talk to your provider immediately about ways to minimize the chances that your baby will become infected, too.
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.

Viral Load & Medications
If someone has HIV, this does not mean that they are restricted to celibacy. Many people with HIV still continue to have safe, enjoyable sex lives without spreading the virus. Always using a condom or barrier method is an important first step to prevent the sharing of HIV containing fluids.
Antiretroviral therapy : Another way to help decrease the risk of spreading HIV is to lower a personâs viral loadâthe amount of HIV in a personâs blood. Viral loads can be lowered using medications called antiretroviral therapy . These medications can lower the HIV viral load so much that HIV may not even be detectable on a blood testâthis is called an undetectable viral load . When a person’s viral load in undetectable, they have effectively no risk of transmitting the HIV virus to a non-infected partner . Taking these medication will help keep a person with HIV healthy while also helping prevent the spread of HIV to another person. This is not a cure, however. If medication is taken incorrectly or stopped, HIV viral loads will increase again and transmission can occur. Condoms and other barrier methods should still always be used during sex .
What Is The Risk Of Hiv From Anal Sex
The risk of HIV through unprotected anal intercourse is seen to be extremely high, as much 18 times greater than vaginal intercourse. The reasons for the increased risk are well known and include such factors as:
- The fragility of rectal tissues, which allow the virus direct access into the bloodstream through tiny tears or abrasions
- The porousness of rectal tissues, providing access even when undamaged
- The high concentration of HIV in semen and pre-seminal fluid , which doubles the risk of infection with every one-log rise in the person’s viral load.
Furthermore, the secretion of blood from damaged rectal tissues can increase the risk for the insertive partner, providing the virus a route of transmission through the urethra and tissues that line the head of the penis .

Are Hiv Medicines Used At Other Times To Prevent Hiv Transmission
Yes, HIV medicines are also used for post-exposure prophylaxis and to prevent mother-to-child transmission of HIV.
- Post-exposure prophylaxis PEP means taking HIV medicines within 72 hours after a possible exposure to HIV to prevent HIV infection. PEP should be used only in emergency situations. It is not meant for regular use by people who may be exposed to HIV frequently. For more information, read the ClinicalInfo fact sheet on Post-Exposure Prophylaxis .
- Prevention of mother-to-child transmission of HIV Pregnant women with HIV take HIV medicines for their own health and to prevent mother-to-child transmission of HIV. After birth, babies born to women with HIV receive HIV medicine to protect them from infection with any HIV that may have passed from mother to child during childbirth. For more information, read the ClinicalInfo fact sheet on Preventing Mother-to-Child Transmission of HIV.
What Behaviors Are The Most Risky For Getting Or Transmitting Hiv
Since there is a fairly high number of people who have HIV and dont know it, you should be tested for HIV so you know your status. Being intoxicated is risky because you are more likely to engage in risky sex if you are drunk or high. In terms of sex acts, anal sex and vaginal intercourse are the most risky behaviors.

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.
Tattoos And Body Piercings
- There are no known cases in the United States of anyone getting HIV this way.
- However, it is possible to get HIV from tattooing or body piercing if the equipment used for these procedures has someone elses blood in it or if the ink is shared. This is more likely to happen when the person doing the procedure is unlicensed because of the potential for unsanitary practices such as sharing needles or ink.
- If you get a tattoo or a body piercing, be sure that the person doing the procedure is properly licensed and that they use only new or sterilized needles, ink, and other supplies.

What Are The Tests For Detecting Hiv
Various tests may be used for HIV detection:
- HIV antibody test: This test detects the antibodies produced in the body in response to HIV.
- Antigen test: This test can be done at an earlier stage than an HIV antibody test. It measures a protein called p24 antigen, present in the virus and produced in high amounts after the infection.
- Nucleic acid test : It is also called an RNA test. It is a very specific test that looks for the virus itself and can detect HIV as early as about 10 days of infections.
- In-home test kits: Although less accurate than the laboratory-based tests, home-based kits have the advantage of testing in the privacy and comfort of the home. Only FDA approved home-based kits should be used.
- Viral culture: This involves using the patients sample and growing the virus in the lab. It takes longer to get the results and is not the most preferred test for HIV.
Hiv Blood Tests And Results
A specialist can test for HIV utilizing a particular blood test. A positive outcome implies that they have recognized HIV immunizer in the circulation system. The blood is re-tried before a positive result gets given. After the expected presentation to the infection, early testing and analysis are essential and enormously improves the odds of fruitful treatment. Home testing packs are additionally accessible.
HIV may take 3 and a half year to appear in testing and re-testing might be essential for a complete determination. Individuals in danger of disease inside the most recent a half year can have a quick test. The test supplier will regularly suggest another test inside half a month.

How Can To Help Stop The Spread Of Hiv
To lower the risk of getting HIV and other STIs:
- Those who are HIV-negative should consider PrEP. If a possible HIV exposure occurs, PEP may provide emergency protection.
- Use condoms during vaginal and anal sex.
- Get tested and treated for STIs and follow healthcare providers recommended screening schedule.
- Before having sex with someone, ask them to get tested for HIV and STIs.
- Those who inject drugs should get clean needles from a needle exchange.
- Avoid sharing needles for drugs and tattoos.
Talk to a healthcare provider about PrEP if a sexual partner has HIV with a detectable viral load or theres another known risk of contracting the virus. Heres a search tool for finding healthcare providers who prescribe PrEP.
Anyone who thinks they might have contracted HIV needs to get tested immediately. Early treatment can help manage the symptoms, lower the risk of complications, lower the risk of transmitting HIV to a sexual partner, and help people to live a long and healthy life.
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.

How Do People Get Aids
AIDS stands for acquired immunodeficiency syndrome, a disease that makes it hard for the body to fight off infectious diseases. The human immunodeficiency virus causes AIDS by infecting and damaging part of the bodys defenses against infection, namely the white blood cells known as CD4 helper lymphocytes .
How does someone become infected? HIV can be spread through any type of unprotected sex if one of the partners has the virus. This can happen when body fluids such as semen , vaginal fluids, or blood from an infected person get into the body of someone who is not infected. Someone can become infected even if only tiny amounts of these fluids are spread. Everyone who has unprotected sex with an infected person is at risk of contracting HIV, but people who already have another sexually transmitted disease are even more at risk.
HIV can be spread sexually from a guy to a girl, a girl to a guy, a guy to a guy, and a girl to a girl.
Sharing needles to inject drugs or steroids is another way that HIV can be passed to other people. Sharing of needles for tattoos, piercings, and body art can also lead to infection. Someone with HIV who shares a needle also shares the virus, which lives in the tiny amounts of blood attached to the needle. Sharing needles also can pass hepatitis and other serious infections to another person.
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.

Why Genital Herpes Boosts The Risk Of Hiv Infection
Scientists have discovered why people who develop genital herpes sores are at higher risk of contracting HIV despite successful treatment of the lesions. The new insight may lead to better strategies for HIV prevention.
Genital herpes, caused by the herpes simplex virus type 2 , is one of the most common sexually transmitted infections worldwide. It is also associated with a 2- to 3-fold increased risk for HIV infection. Some people infected with HSV-2 suffer from recurring sores and breaks in genital skin. Researchers hypothesized that these lesions account for the higher risk for HIV. However, recent clinical trials that successfully treated genital herpes lesions with the anti-viral drug acyclovir didn’t reduce the risk of HIV infection.
A team led by Dr. Lawrence Corey and Dr. Jia Zhu of the Fred Hutchinson Cancer Research Center and Dr. Anna Wald of the University of Washington sought to understand why genital herpes boosts the risk of HIV infection even after treatment with oral acyclovir and the healing of genital lesions. Their work was funded by NIH’s National Institute of Allergy and Infectious Diseases and Eunice Kennedy Shriver National Institute of Child Health and Human Development .
In further experiments, the scientists found that HIV replicates 3 to 5 times as quickly in cultured tissue from the sites of healed HSV-2 lesions as in cultured tissue from control sites.

- 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.
I Am Hiv Positive How Can I Prevent Passing Hiv To Others
Take HIV medicines daily. Treatment with HIV medicines helps people with HIV live longer, healthier lives. ART can’t cure HIV, but it can reduce the amount of HIV in the body . One of the main goals of ART is to reduce a person’s viral load to an undetectable level. An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. People with HIV who maintain an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
Here are some other steps you can take to prevent HIV transmission:
- Use condoms correctly every time you have sex.
- Talk to your partner about taking PrEP.
- If you inject drugs, don’t share your needles, syringes, or other drug equipment with your partner.

How Do You Get Hiv
HIV is carried in semen , vaginal fluids, anal mucus, blood, and breast milk. The virus gets in your body through cuts or sores in your skin, and through mucous membranes . You can get HIV from:
having vaginal or anal sex
sharing needles or syringes for shooting drugs, piercings, tattoos, etc.
getting stuck with a needle that has HIV-infected blood on it
getting HIV-infected blood, semen , or vaginal fluids into open cuts or sores on your body
HIV is usually spread through having unprotected sex. Using condoms and/or dental dams every time you have sex and not sharing needles can help protect you and your partners from HIV. If you do have HIV, treatment can lower or even stop the chances of spreading the virus to other people during sex. If you dont have HIV, theres also a daily medicine called PrEP that can protect you from HIV.
HIV can also be passed to babies during pregnancy, birth, or breastfeeding. A pregnant woman with HIV can take medicine to greatly reduce the chance that her baby will get HIV.
HIV isnt spread through saliva , so you CANT get HIV from kissing, sharing food or drinks, or using the same fork or spoon. HIV is also not spread through hugging, holding hands, coughing, or sneezing. And you cant get HIV from a toilet seat.
