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.
Symptoms And Stages Of Hiv Infection
- There are three stages of HIV infection. The symptoms vary in type and severity from person-to-person.
- Stage 1 after initial infection can feel like flu but not everyone will experience this.
- Stage 2 is when many people start to feel better and may last for 10 years or more. During this time a person may have no symptoms.
- Stage 3 is when a persons immune system is very badly damaged and can no longer fight off serious infections and illnesses.
- The earlier a person is diagnosed with HIV and starts treatment, the better their health will be over time.
- Some people dont get any symptoms during stages 1 and 2, and may not know they have the virus, but they can still pass on HIV.
The signs of HIV infection can vary in type and severity from person-to-person, and some people may not have any symptoms for many years.
The stages below describe how HIV infection progresses in the body if it is left untreated. Without antiretroviral treatment for HIV, the virus replicates in the body and causes more and more damage to the immune system.
However with effective treatment, you can keep the virus under control and stop it from progressing. This is why its important to start treatment as soon as possible after testing positive.
When To Get Tested For Hiv After Exposure
Frequently Asked Questions. One recommended strategy is to get tested 2-4 weeks, 3 months, and 6 months after a risky exposure. Using a sensitive antigen/antibody HIV test, of those who are infected, most will test positive at 1 month almost all will test positive at 3 months and the rest will test positive at 6 months.

Calculating Life Expectancy With Hiv Or Aids
Recent research shows that a young person with HIV or AIDS could potentially live almost as long as anyone else in the general population. But this is only the case if they have routine access to health care and respond well to modern antiretroviral treatments . So a 20-year-old who starts on ARTs today, for example, might eventually live to be 67.
Keep in mind though, since there is no known cure, HIV life expectancy varies greatly from one individual to the next based on many things. This includes early detection plus, gender and lifestyle choices such as alcohol, tobacco, or drug use.
Over the past two decades, HIV life expectancy has drastically risen. What was once considered a terminal illness is now a medically manageable condition at any age. Those who abuse intravenous drugs or possess a preexisting immune disorder, however, do not fare as well.
In light of huge disparities in access to health care and ARTs, the CDC regularly publishes reports on obstacles to HIV and AIDS treatment. By 2016, it was estimated that 1.1 million people in the U.S., aged 13 or older, had HIV .
How Many Days After Hiv Do Rashes Appear
Early symptoms of an HIV infection that can occur alongside a rash include: According to the Centers for Disease Control and Prevention , these symptoms may appear 2-4 weeks after exposure and last between a few days and several weeks. Anyone who experiences these symptoms after possible exposure to HIV should seek advice about testing.

What Is Acute Hiv Infection
There are three stages of HIV infection:
- Stage 1:Acute HIVinfection
- Stage 2:Chronic HIV infection
- Stage 3:AIDS
Acute HIV infection is the first stage of the infection. Usually within two to four weeks of infection, two-thirds of those with HIV will experience flu-like symptoms. These symptoms may last for several days or even weeks. However, some people may experience no symptoms at all.
In this stage, there is a large amount of HIV in your blood, which is known as the viral load. Studies have noted incredibly high viral loads during the acute stage, meaning you are more contagious at this time.
How Long Does It Take Before Hiv Symptoms Appear
HIV-disease has four stages. The first stage and last two are symptomatic, while the second and longest, latency, have no symptoms. The appearance of symptoms varies greatly, based on whether the individual is taking anti-retroviral therapy, general health and other variables.
Acute HIV Infection
Within the first month after infection, some people experience a flu-like illness that lasts for about 2 weeks. Symptoms include fever, headache and muscle aches, swollen lymph nodes, diarrhea, nausea and lack of appetite, and skin rash .
Latency is the longest stage of HIV disease. During this time, there are no symptoms of HIV. This period lasts for an average of 10 years but sometimes lasts up to 25.
Symptomatic HIV occurs after latency and generally lasts 1 to 3 years. Symptoms include persistent swollen lymph nodes, fatigue, diarrhea, night sweats, fever, skin and breathing problems.
AIDS follows symptomatic HIV when CD4+ cell counts fall below 200 per cubic milliliter of blood. Stage 4 HIV disease might follow HIV infection by more than 20 years and depends greatly on whether treatment has been administered, whether it has been effective and how well the persons general health has been maintained .

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.
When Do The Symptoms Of Hiv Go Away
These early HIV symptoms are called acute retroviral syndrome or acute HIV infection and are the bodys natural response. Symptoms, if they appear at all, usually disappear within a week to a month and are often mistaken for those of another viral infection. During this period, you are very infectious.

Individual Symptoms Of Hiv Vary From One Person To Another If You Have An Active Sex Life Or Think You May Have Been Exposed To Hiv It Is Important To Get Tested Here Are Some Common Symptoms Of Hiv Many People Experience Severe Flu
Symptoms of HIV can vary between individuals however the first signs of infection generally appear within the first 1-2 months. Many, but not all, people will experience severe flu-like symptoms which is your bodys natural response to the virus. This is called the seroconversion period.
Its during this time that its crucial to identify if HIV is the cause, as your viral load is very high which greatly increases the risk of passing it on. And the only way to know for sure is by getting tested.
Stage : Clinical Latency
In this stage, the virus still multiplies, but at very low levels. People in this stage may not feel sick or have any symptoms. This stage is also called chronic HIV infection.
Without HIV treatment, people can stay in this stage for 10 or 15 years, but some move through this stage faster.
If you take HIV medicine every day, exactly as prescribed and get and keep an undetectable viral load, you can protect your health and have effectively no risk of transmitting HIV to your sexual partner.
But if your viral load is detectable, you can transmit HIV during this stage, even when you have no symptoms. Its important to see your health care provider regularly to get your viral load checked.

Can Hiv Be Prevented Or Avoided
The best way to prevent HIV is to not have sex with a person who has HIV, or share a needle with a person who has HIV. However, there is also a medicine called PrEP that people can take before coming into contact with HIV that can prevent them from getting an HIV infection.
PrEP stands for pre-exposure prophylaxis. It is for people who are at long-term risk of getting HIV either through sexual activity or by injecting drugs. If youre taking PrEP and come into contact with HIV, the medicine makes it difficult for HIV to develop inside your body.
Other ways to prevent HIV include:
- When you have sex, practice safer sex by using a condom. The best condom is a male latex condom. A female condom is not as effective but does offer some protection.
- Do not share needles and syringes.
- Never let someone elses blood, semen, urine, vaginal fluid, or feces get into your anus, vagina, or mouth.
Symptom : Night Sweats
Many people will get night sweats during the early stages of HIV. These can be even more common later in infection and arent related to exercise or the temperature of the room.
With such a vast array of symptoms, HIV testing is vital to ensure a proper diagnosis. If you think youve been exposed to HIV, or have an active sex life with casual sex partners, regardless of whether you are showing symptoms of HIV or not, its important to get tested as soon as possible.

How Likely Are You To Experience Symptoms During The Early Stage Of Hiv
According to the American Academy of Family Physicians , at least 50 to 90 per cent of the individuals who contract HIV will experience some of the acute symptoms. In a study that AAFP carried out among HIV-positive patients, 80 to 90 per cent had fever in the acute stage, fatigue was common among 70 to 90 per cent, followed by rashes and headaches .
Its very important to understand the fact that even if you do not have any symptoms, HIV becomes transmissible as soon as it enters the body. Theres a common misconception that a person can pass the virus to someone else only after they become symptomatic. This is not true and the belief is very dangerous.
Early HIV symptoms are very non-specific. You could think that youre coming down with a cold. In some time, the symptoms will get resolved and youll probably forget about the situation.
Getting tested will show you exactly whats going on.
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.
- Breast tissue growth
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.

Regular Hiv Testing: The Only Reliable Method To Find The Truth
Before the development of the acute stage of HIV, the virus wouldnt have multiplied enough to be properly detected during regular screening.
A general recommendation is to wait anywhere between two and four weeks after potential exposure to get tested. If you get HIV screening earlier than that, you may end up with a false negative test that gives you a sense of security.
As per general recommendations, everyone who is sexually active should get HIV and STD screening at least once per year as a part of their regular health check-up. Even those in a monogamous, committed relationship can benefit from learning a bit more about their status.
HIV screening is readily available in Singapore. Multiple types of tests can be employed. Some of them ensure quick results. You will know your status in a matter of minutes. Others are much more reliable/accurate but the results will become available after thorough analysis that may take several days.
Visiting a reputable medical facility like Shim Clinic will give you a much better idea about the available kinds of tests, the potential prevention and the risky behaviours you could have been engaging in without understanding the associated dangers.

Aids Is The Final Stage
Controlling HIV with medications is crucial to both maintaining quality of life and helping prevent progression of the disease. Stage 3 HIV, also known as AIDS, develops when HIV has significantly weakened the immune system.
According to the CDC National Prevention Information Network, CD4 levels give one indication that HIV has progressed to its final stage. CD4 levels decreasing below 200 cells per cubic millimeter of blood is considered a sign of AIDS. A normal range is considered 500 to 1,600 cells/mm3.
AIDS can be diagnosed with a blood test to measure CD4. Sometimes its also determined simply by a persons overall health. In particular, an infection thats rare in people who dont have HIV may indicate AIDS. Symptoms of AIDS include:
- persistent high fevers of over 100°F
AIDS is the final stage of HIV. According to AIDSinfo, it takes at least 10 years without treatment for most people with HIV to develop AIDS.
At that point, the body is susceptible to a wide range of infections and cant effectively fight them off. Medical intervention is necessary to treat AIDS-related illnesses or complications that can otherwise be fatal. Without treatments, the CDC estimates the average survival rate to be three years once AIDS is diagnosed. Depending on the severity of their condition, a persons outlook may be significantly shorter.

What Are The Signs & Symptoms Of Hiv And Aids
When first infected with HIV, a person may have:
- increased number of infections
- infections that are more severe than is typical
Without treatment, HIV can lead to a very weakened immune system and progress to AIDS. Illnesses that happen in AIDS are called “AIDS-defining conditions.”
AIDS-defining conditions include:
- very fast and severe weight loss
- a lung infection called pneumocystis pneumonia
- Kaposi sarcoma
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.
