Children Older Than 18 Months
When fetuses develop within the womb, they receive nourishment from the pregnant parent through the placenta. If the pregnant parent has HIV, the placenta also transfers HIV antibodies to the fetus. For this reason, all infants birthed by a parent with HIV will test positive for the antibodies at birth.
After birth, antibodies for HIV from the birthing parent can remain in the blood for up to 18 months. Once children are over 18 months old, doctors use the HIV antibody test to make a diagnosis.
What Is The Treatment For Hiv
Antiretroviral therapy is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines every day.
ART is recommended for everyone who has HIV. ART prevents HIV from multiplying, which reduces the amount of HIV in the body . Having less HIV in the body protects the immune system and prevents HIV infection from advancing to AIDS. ART cannot cure HIV, but HIV medicines help people with HIV live longer, healthier lives.
ART also reduces the risk of HIV transmission. A main goal of ART is to reduce a persons 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 their HIV-negative partner through sex.
What Are The 3 Stages Of Hiv When Does Hiv Infection Transition To Aids
There are 3 stages of HIV infection.
- Stage 1: Flu-like symptoms after initial HIV infection
- Stage 2: Clinically latency may last for 10 or more years in some individuals
- Stage 3: After HIV reactivation and/or HIVs progressive attack on the immune system, the damaged immune system has a reduced or an inability to protect the individual from serious infections and other illnesses. This stage is termed AIDS. In this stage, lab testing reveals high viral loads and CD4 counts < 200 cells/mm3.

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:
- From mother to child during pregnancy, birth, or breastfeeding. However, the use of HIV medicines and other strategies have helped lower the risk of mother-to-child transmission of HIV to 1% or less in the United States.
- Getting stuck with an HIV-contaminated needle or other sharp object. This is a risk mainly for health care workers. The risk is very low.
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.
Treatment Options For Hiv
Treatment should begin as soon as possible after a diagnosis of HIV, regardless of viral load.
The main treatment for HIV is antiretroviral therapy, a combination of daily medications that stop the virus from reproducing. This helps protect CD4 cells, keeping the immune system strong enough to take measures against disease.
Antiretroviral therapy helps keep HIV from progressing to AIDS. It also helps reduce the risk of transmitting HIV to others.
When treatment is effective, the viral load will be undetectable. The person still has HIV, but the virus is not visible in test results.
However, the virus is still in the body. And if that person stops taking antiretroviral therapy, the viral load will increase again, and the HIV can again start attacking CD4 cells.

What Are The Symptoms Of Hiv
After the first month or so, HIV enters the clinical latency stage. This stage can last from a few years to a few decades.
Some people dont have any symptoms during this time, while others may have minimal or nonspecific symptoms. A nonspecific symptom is a symptom that doesnt pertain to one specific disease or condition.
These nonspecific symptoms may include:
- headaches and other aches and pains
- swollen lymph nodes
- recurrent oral or vaginal yeast infections
- pneumonia
- shingles
As with the early stage, HIV is still transferable during this time even without symptoms and can be transmitted to another person.
However, a person wont know they have HIV unless they get tested. If someone has these symptoms and thinks they may have been exposed to HIV, its important that they get tested.
HIV symptoms at this stage may come and go, or they may progress rapidly. This progression can be slowed substantially with treatment.
With the consistent use of this antiretroviral therapy, chronic HIV can last for decades and will likely not develop into AIDS, if treatment was started early enough.
The cause of the rash determines:
- how it looks
- how it can be treated depends on the cause
Second Stage: Clinical Latency Symptoms
After your immune system loses the battle with HIV, the flu-like symptoms will go away. But thereâs a lot going on inside your body. Doctors call this the asymptomatic period or chronic HIV infection.
In your body, cells called CD4 T cells coordinate your immune systemâs response. During this stage, untreated HIV will kill CD4 cells and destroy your immune system. Your doctor can check how many of these cells you have with blood tests. Without treatment, the number of CD4 cells will drop, and youâll be more likely to get other infections.
Most people don’t have symptoms they can see or feel. You may not realize that you’re infected and can pass HIV on to others.
If youâre taking ART, you might stay in this phase for decades. You can pass the virus on to other people, but itâs extremely rare if you take your medicines.

Can Hiv Be Prevented
To reduce the risk of getting HIV, people who are sexually active should:
- use a condom every time they have sex
- get tested for HIV and make sure all partners do too
- reduce their number of sexual partners
- get tested and treated for STDs having an STD increases the risk of HIV infection
- consider taking a medicine every day if they are at very high risk of getting infected
For everyone:
- Do not inject drugs or share any kind of needle.
- Do not share razors or other personal objects that may touch blood.
- Do not touch anyone else’s blood from a cut or sore.
Changing Attitudes About Hiv
When someone is diagnosed with HIV, other people may have negative attitudes and beliefs about that person’s behaviour, lifestyle or circumstances in life. These negative associations form what’s called stigma, an experience that can decrease quality of life because it includes:
- judging
Efforts to end stigma will help to:
- prevent new infections
- ensure that people living with HIV receive the care, treatment and support they need

What Is The Difference Between Hiv And Aids
The term AIDS refers to the most advanced stages of HIV infection. Most of the conditions affecting people with AIDS are opportunistic infections that generally do not affect healthy people. In people with AIDS, these infections are often severe and sometimes fatal because the immune system is so ravaged by HIV that the body cannot fight off the infection. Symptoms of opportunistic infections common in people with AIDS include:
- coughing and shortness of breath
- seizures and lack of coordination
- difficult or painful swallowing
- severe headaches
- coma
People with AIDS also are particularly prone to developing various cancers. These cancers are usually more aggressive and difficult to treat in people with AIDS.
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.

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.
How To Tell If Symptoms Are Hiv
There are three types of HIV tests:
- An NAT involves drawing blood from a vein. It can tell if you have HIV or how much virus is present in your blood. While an NAT can detect HIV sooner than other types of tests, this test is very expensive and not routinely used for screening individuals unless they recently had a high-risk exposure, or a possible exposure and have early symptoms of HIV infection. This test takes several days for results to come back.
- An antigen/antibody test is recommended for testing done in labs and is now common in the United States. It involves drawing blood from a vein, and results take several days to come back. There is also a rapid antigen/antibody test available that is done with a finger prick and takes 30 minutes or less to get results.
- HIV antibody tests only look for antibodies to HIV in your blood or oral fluid. In general, antibody tests that use blood from a vein can detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid. Antibody tests can detect an HIV infection 23 to 90 days after exposure. Most rapid tests and the only currently approved HIV self-test are antibody tests. They take 20 minutes or less to provide results.
Keep in mind, any positive result would necessitate a second test to confirm it. The only test that would not require a second confirmatory test is the NAT.

Who Is At Risk For Hiv Infection
Anyone can get HIV, but certain groups have a higher risk of getting it:
- People who have another sexually transmitted disease . Having an STD can increase your risk of getting or spreading HIV.
- People who inject drugs with shared needles
- Gay and bisexual men, especially those who are Black/African American or Hispanic/Latino American
- People who engage in risky sexual behaviors, such as not using condoms
How Is Hiv Treated
There is no vaccine or cure for HIV infection. However, there are effective treatments that can help prevent the progression to AIDS and help ensure a near-normal life expectancy.
These treatments are known as antiretroviral therapy. They stop the virus from reproducing itself, which leads to a lower viral load. The treatment involves a combination of drugs used together.
Improvements in treatment now mean that HIV infection is a manageable chronic disease for many people in countries like Australia. People with HIV who are effectively treated are also highly unlikely to pass the virus on to others.

Are Women More Likely To Get Hiv
Yes. Biologically speaking, a woman is more vulnerable to heterosexual transmission of the disease because the genitalia are easily exposed to seminal fluids.
Gender inequality has great influence on the spread of HIV/AIDS among women. In some cultures, many women and girls are often put in situations where they engage in non-consensual sex or have sex for money.
In the U.S., minority communities have been hit the hardest by HIV. African American and Hispanic women together represent less than 25% of all U.S. women, yet they account for more than 78% of AIDS cases reported among women in the country.
How Can I Know If I Have Hiv
The only way to know if you have HIV is to take an HIV test. Many medical groups recommend routine voluntary HIV screening of all patients aged 18 to 75 years of age as a normal part of medical care. The reason for this is that nearly one out of seven people infected with HIV are not aware that they have the infection.

There is no cure for HIV infection, but it can be treated with medicines. This is called antiretroviral therapy . ART can make HIV infection a manageable chronic condition. It also reduces the risk of spreading the virus to others.
Most people with HIV live long and healthy lives if they get and stay on ART. It’s also important to take care of yourself. Making sure that you have the support you need, living a healthy lifestyle, and getting regular medical care can help you enjoy a better quality of life.
What Is Hiv And Aids
HIV stands for human immunodeficiency virus, which is the virus that causes HIV infection. The abbreviation HIV can refer to the virus or to HIV infection.
AIDS stands for acquired immunodeficiency syndrome. AIDS is the most advanced stage of HIV infection.
HIV attacks and destroys the infection-fighting CD4 cells of the immune system. The loss of CD4 cells makes it difficult for the body to fight off infections and certain cancers. Without treatment, HIV can gradually destroy the immune system and HIV infection advances to AIDS.

How Is Aids Diagnosed
Symptoms such as fever, weakness, and weight loss may be a sign that a persons HIV has advanced to AIDS. However, a diagnosis of AIDS is based on the following criteria:
- A drop in CD4 count to less than 200 cells/mm3. A CD4 count measures the number of CD4 cells in a sample of blood.OR
- The presence of certain opportunistic infections.
Although an AIDS diagnosis indicates severe damage to the immune system, HIV medicines can still help people at this stage of HIV infection.
Causes Or Mode Of Infection
The HIV infects the macrophages in the blood. Once they infect, the viral RNA enters the host cell and produces DNA with the help of reverse transcription. This viral DNA, then integrates into the host genome and produces multiple RNA copies by the process of transcription. These RNAs then form multiple copies of the virus and continue the infection in the same way.
At the same time, HIV also enters the T lymphocytes and continues the same set of events as it does in macrophages. This leads to a decrease in the number of helper T lymphocytes. Thus, the immunity of the body is considerably compromised. The immunity is lowered to such an extent that the infected person suffers from even minor infections, which is one of AIDS characteristic symptoms. Other symptoms include bouts of fever, diarrhoea and significant weight loss.

Diagnosis In Men Vs Women
Doctors diagnose HIV in both men and women by testing a blood or saliva sample, although they could also test a urine sample. This test looks for antibodies produced by the person to fight the virus. The test typically takes around 3 to 12 weeks to detect antibodies.
Another test looks for HIV antigens, which are substances that the virus produces immediately after transmission. These antigens cause the immune system to activate. HIV produces the p24 antigen in the body even before antibodies develop.
Usually, both the antibody and the antigen tests are done in labs, but there are also home tests that people can take.
Home tests may require a small sample of blood or saliva, and their results are quickly available. If the test is positive, it is essential to confirm the results with a doctor. If the test is negative, a person should repeat it after a few months to confirm the results.
What You Can Do To Reduce Stigma
You can help reduce stigma by being respectful, compassionate and non-judgemental. Model this behaviour for others when you witness stigmatizing behaviours.
When talking about HIV, certain terms can be stigmatizing. Be thoughtful about the words you use when discussing the topic.
Learn more about the facts of HIV. Treatment can lower the amount of virus in a person’s blood to a level that’s too low to be measured on a standard blood test. This means it’s undetectable.
People living with HIV on treatment who maintain an undetectable viral load have effectively no risk of transmitting HIV to their sexual partners.
Knowing and sharing these facts widely can help to reduce stigma. Share our Undetectable = Untransmittable infographic to help us raise awareness.
