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.
Benefits Of Early Detection
Recognizing the symptoms of ARS is important as it affords a person the opportunity for early detection. This not only helps ensure that HIV is not spread to others, but offers benefits in the way of early treatment.
Studies published in 2013 indicate that the early initiation of antiretroviral therapy correlates to a reduced risk of both HIV-related and AIDS-defining illnesses. By contrast, delaying therapy until a persons CD4 count drops below 350 cells/mL is associated with not only more adverse clinical events, but a significantand even profoundreduction in life years.
Early treatment prevents often-irreversible damage to the immune system. It also reduces the risk of passing the virus to others, a strategy known as treatment as prevention .

What Is Usually The First Sign Of Hiv
HIV, or the human immunodeficiency virus, exists within the bodies of more than 1.2 million Americans. Each year, more than 35,000 new infections emerge. If left untreated, the virus can lead to acquired immunodeficiency syndrome .
Since the beginning of the AIDS epidemic, more than 700,000 Americans have died from complications stemming from this disease. Even though HIV is no longer in the news all that often, it is clear that the disease continues to make an impact in this country. This blog will help you understand HIV, the symptoms of the disease, and how you can get help.

Symptoms Of Aids In Women
The symptoms of AIDS vary little between women and men. There are some variations, including evidence that women with HIV experience greater cognitive decline and may be more likely to experience signs of HIV encephalopathy than men.
The one AIDS-defining condition exclusive to women is invasive cervical cancer . This is the advanced stage of cervical cancer in which tumor cells have spread to tissues deeper within the cervix or to other parts of the body. Though ICC can affect both HIV-positive and HIV-negative women, the incidence among women with HIV is up to seven times greater.
As with other HIV-associated conditions, the risk of ICC increases with declines in the CD4 count. Women with CD4 counts under 200 are six times more likely to get ICC than those whose CD4 counts over 500.
Arguably more concerning is the fact that the incidence of ICC among women with HIV has remained largely unchanged since the 1990s. This is unlike other AIDS-defining conditions that are rarely seen today due to the advent of combination antiretroviral therapy.
Though the reasons for this remain unclear, some studies have suggested that women with HIV are more likely to be infected by less prevalent high-risk strains of HPV that current vaccines cannot protect against.

Hiv Among Black Msm And Trans People
Signs of acute HIV are the same for all people, no matter their race or sex. With that said, Black people and men who have sex with men account for the lion’s share of new HIV diagnoses. Black trans people, with emphasis on Black trans women and feminine people, also have higher chances of testing positive for HIV than the general population. Studies show stigma, lack of access to health care, and discrimination contribute to the high rate of diagnosis in these populations. Reports have shown 62% of Black trans women in the United States are living with HIV. The Black trans community at large, including Black transmasculine people, test HIV positive at higher rates than the broader population. Roughly 30% of all new cases are among Black MSM who have no less than a 50/50 chance of getting HIV in their lifetime.
Symptom : Nausea Vomiting And Diarrhoea
Many people experience digestive system problems as a symptom of the early stages of HIV. However, nausea, vomiting and diarrhoea can also appear in later stages of infection, usually as the result of an opportunistic infection.
It is important to stay hydrated. Diarrhoea that is unremitting and not responding to usual therapy might be an indication of HIV, and it would be best to seek the advice of a doctor to help determine its cause.

First Stage: Acute Hiv Infection Symptoms
Most people don’t know right away when they’ve been infected with HIV. But they may have symptoms within 2 to 6 weeks after theyâve gotten the virus. This is when your body’s immune system puts up a fight. It’s called acute retroviral syndrome or primary HIV infection.
The symptoms are similar to those of other viral illnesses, and they’re often compared to the flu. They typically last a week or two and then go away. Early signs of HIV include:
- Ulcers in your mouth, esophagus, anus, or genitals
- Headache and other neurological symptoms
If you have symptoms like these and might have come into contact with someone with HIV in the past 2 to 6 weeks, go to a doctor and ask that you get an HIV test. If you donât have symptoms but still think you might have come into contact with the virus, get tested.
Early testing is important for two reasons. First, at this stage, levels of HIV in your blood and bodily fluids are very high. This makes it especially contagious. Second, starting treatment as soon as possible might help boost your immune system and ease your symptoms.
A combination of medications can help fight HIV, keep your immune system healthy, and keep you from spreading the virus. If you take these medications and have healthy habits, your HIV infection probably wonât get worse.
Needle And Syringe Programs
Needle and syringe programs provide clean needles or syringes to people who inject drugs, reducing the risk of the transmission of HIV and other blood-borne diseases such as hepatitis B and hepatitis C. This is sometimes referred to as needle exchange.
The types of NSP outlet vary, from participating pharmacies to vending machines. Find an NSP in your state or territory:
You can also find a local needle and syringe program using the healthdirect Service Finder. Select By name and type needle into the search bar.

Days To 20 Years After Exposure
The chronic stage of infection occurs once the immune system brings the virus under control. During this phase, HIV will go into hiding, where it resides in various cells and tissues throughout the body in a dormant state known as latency. HIV latency can persist without symptoms for 10 years or more, although some people may experience signs within a year or two.
During the early chronic phase, lymphadenopathy may be the only notable sign of an HIV infection. In some cases, the glands may be visibly enlarged and reach up to an inch or more in size. If the condition persists for more than three months, its referred to as persistent generalized lymphadenopathy .
Even during latency, the virus will multiple imperceptibly and gradually deplete immune cells known as CD4 T-cells. As immune deficiency develops, a number of nonspecific symptoms are likely to appear, including:
- Oral candidiasis , a fungal infection that causes the formation of creamy, white lesions on the sides of the tongue and lining of the mouth
- Unexplained fevers and drenching night sweats that soak through bedsheets and nightclothes
- Severe, uncontrolled diarrhea that lasts for more than three days
Each of these symptoms is commonly seen in persons with immune deficiency. They may, in some cases, be caused by HIV itself or by an infection that has yet to be diagnosed.
Stage : Acute Hiv Infection
Within 2 to 4 weeks after infection with HIV, about two-thirds of people will have a flu-like illness. This is the bodys natural response to HIV infection.
Flu-like symptoms can include:
- Swollen lymph nodes
- Mouth ulcers
These symptoms can last anywhere from a few days to several weeks. But some people do not have any symptoms at all during this early stage of HIV.
Dont assume you have HIV just because you have any of these symptomsthey can be similar to those caused by other illnesses. But if you think you may have been exposed to HIV, get an HIV test.

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.
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.

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.
When To Seek Medical Care
Early diagnosis is key. If you think youve been exposed to HIV or have an encounter that put you at risk for HIV, you should seek medical care right away with a primary care doctor, urgent or walk-in clinic, or, if those are not available to you, a local emergency room.
Doctors can give you a medication called post-exposure prophylaxis after exposure to reduce your chances of developing HIV. But this medication needs to be taken within 72 hours of exposure. Ideally, youd start taking it within the first 24 hours.
If you think you were exposed to HIV in the past for example, if a former sexual partner tells you they have HIV its critical to seek medical care as soon as possible. The sooner you find out you have HIV, the sooner you can start treatment.

Rash Related To Medication
While rash can be caused by HIV co-infections, it can also be caused by medication. Some drugs used to treat HIV or other conditions can cause a rash.
This type of rash usually appears within a week or 2 weeks of starting a new medication. Sometimes the rash will clear up on its own. If it doesnt, a change in medications may be needed.
Rash due to an allergic reaction to medication can be serious.
Other symptoms of an allergic reaction include:
- trouble breathing or swallowing
- dizziness
- fever
Stevens-Johnson syndrome is a rare allergic reaction to HIV medication. Symptoms include fever and swelling of the face and tongue. A blistering rash, which can involve the skin and mucous membranes, appears and spreads quickly.
When 30 percent of the skin is affected, its called toxic epidermal necrolysis, which is a life threatening condition. If this develops, emergency medical care is needed.
While rash can be linked with HIV or HIV medications, its important to keep in mind that rashes are common and can have many other causes.
Symptoms Specific To Men
It’s important to note that these male-specific symptoms can also be signs of other conditions. If you have any of these, make sure to speak with your doctor.
Low sex drive. This is a sign of hypogonadism, which means your testicles donât make enough of the sex hormone testosterone. This condition is tied to HIV.Hypogonadism can also cause:
- Breast tissue growth
Sores on the penis. A common sign of HIV is painful open sores, or ulcers on your mouth or esophagus. They can also appear on your anus or penis. These sores often keep coming back.
Pain or burning while peeing. In most cases, this is a symptom of a sexually transmitted infection like gonorrhea or chlamydia. It may signal swelling of the prostate, a small gland beneath the bladder. This condition is called prostatitis. Itâs sometimes caused by a bacterial infection.
Other symptoms of prostatitis include:
- Pain during ejaculation
- Peeing more often than usual
- Cloudy or bloody pee
- Pain in the bladder, testicles, penis, or the area between the scrotum and rectum
- Lower back, abdomen, or groin pain
If you think you may have been exposed to HIV, see a doctor right away. If itâs been 72 hours or less, you can take something called post-exposure prophylaxis . You take HIV medicine once or twice a day for 28 days that may keep you from getting HIV.
If you have been exposed to HIV, there are other symptoms that aren’t exclusive to men but are important to keep an eye on.

A Timeline Of Hiv Symptoms
What is HIV?
HIV is a virus that compromises the immune system. Theres currently no cure for it, but there are treatments available to reduce its effects on peoples lives.
In the majority of cases, once HIV infection takes hold, the virus stays in the body for life. However, unlike what may occur with infections by other types of viruses, HIV symptoms dont suddenly appear and peak overnight.
If left untreated, the disease progresses over time through three stages, each with its own set of possible symptoms and complications some severe.
Regular antiretroviral treatment can reduce HIV to undetectable levels in the blood. At undetectable levels, the virus wont progress to the later stages of HIV infection. In addition, the virus cant be transmitted to a partner during sex.
How Are Hiv And Aids Treated
Medicines can help people with HIV stay healthy. They can also prevent HIV from progressing to AIDS.
Health care providers prescribe a combination of different medicines for people with HIV and AIDS. They must be taken exactly as prescribed or they won’t work. These medicines:
- help keep the number of CD4 cells high
- reduce the viral load of HIV
Regular blood tests will check the number of CD4 cells in the body and the viral load.
If an HIV-positive person’s CD4 count gets low, doctors prescribe daily antibiotics. This prevents pneumocystis pneumonia, which happens in people with weakened immune systems.
