How Long Does Seroconversion Take

The timeframe between when a person contracts HIV and when tests can detect the infection is known as the window period. Everyones immune system is different. This makes it difficult to predict how long this stage will last.

Scientists have developed sensitive blood tests since the early days of the HIV epidemic. Its now possible to detect HIV antibodies, as well as other components of HIV, earlier than ever before. According to the Johns Hopkins Bloomberg School of Public Health, most people test positive within a few weeks of contracting HIV. For others, it may take

During the window period, a person may develop symptoms similar to the flu or other common viruses that include:

  • swollen lymph nodes
  • rash
  • fever

Symptoms may last from a few days to a few weeks. And they may range from mild to severe. But its possible to pass through the early infection stage without experiencing any symptoms at all. During this time, a person may not even realize that theyve contracted HIV.

How An Hiv Test Works

An HIV test is a blood test. It does not detect HIV itself, but looks for a protein found in an HIV cell, or an antibody made by the body to fight HIV.

HIV tests in the UK are very reliable. They can occasionally produce a positive result which is then found to be negative when tested again. This is called a false positive and is rare, occurring in less than 1 in 1000 cases.

Activities That Transmit Hiv

HIV may pass from one person to another any time there is contact with semen, pre-cum, vaginal fluids or blood. HIV is transmitted during sex and when using injection drugs and sharing needles. Mothers can also transmit HIV to their babies before or during birth or while breastfeeding, although this is very rare in the U.S. and in other places where mothers living with HIV have access to health care services.

People living with HIV who are taking HIV medications and have a suppressed viral load do not transmit HIV. People who are HIV-negative can prevent HIV infection with PrEP.

Bodily fluids that are NOT infectious:

  • Saliva / spit

Remember: Any body fluids that also contain blood may be infectious.

How Long After Hiv Infection Can It Be Detected

HIV is a virus that enters the persons body via sexual intercourse with the infected person and sharing the medical syringes used for injecting drugs is the major cause of AIDS.

The HIV virus is a virus variant that can completely destroy a persons immunity, causing mouth and ulcers as common symptoms. Fatigue, high fever, night sweat, etc. These are the symptoms that can help the person know about the introduction of HIV. HIV is a virus that cannot be cured and stays in the body forever but is controllable using the medicine. If not controlled, it can cause AIDS and completely destroy the immune system.

The HIV virus cannot be detected within a few hours of exposure, and the person must wait at least 72 hours for symptoms to appear and the medical report to show a positive test. The time between exposure and the test is referred to as a time window, and it can vary depending on many factors, most notably the test was chosen.

HIV enters the human body within three stages and can be controlled easily in the early stages. The first stage is acute HIV. At this stage, the body consists of a lot of HIVS in the blood and the symptoms start to show up in the person and enter into the time window.

The second stage is chronic HIV, in which HIV can be spread by these people through common methods, but the HIV in the body is produced at a very low level, but it is still found to be contagious and medical attention is required.

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.

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.

Types Of Hiv Tests And Their Window Periods

  • Nucleic Acid Test A NAT can usually tell you if you have HIV infection 10 to 33 days after exposure
  • Antigen/Antibody TestAn antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after exposure. Antigen/antibody tests done with blood from a finger prick take longer to detect HIV .
  • Antibody TestAn antibody test can take 23 to 90 days to detect HIV infection after an exposure. Most rapid tests and self-tests are antibody tests. In general, antibody tests that use blood from a vein detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid.

Ask your health care provider or test counselor about the window period for the test youre taking and whether you will need a follow-up test to confirm the results. If youre using a self-test, you can get that information from the materials included in the tests package.

If you get an HIV test after a potential HIV exposure and the result is negative, get tested again after the window period. Remember, you can only be sure you are HIV-negative if:.

  • Your most recent test is after the window period
  • You havent had a potential HIV exposure during the window period. If you do have an exposure, then you will need to be retested.

Types Of Condomless Sex And Risk Of Hiv

Real Question: How Long Does it Take to Test Positive for HIV?

During condomless sex, HIV in the bodily fluids of one person may be transmitted to the body of another person through the mucous membranes of the penis, vagina, and anus. In very rare cases, HIV could potentially be transmitted through a cut or sore in the mouth during oral sex.

Out of all types of condomless sex, HIV can most easily be transmitted during anal sex. This is because the lining of the anus is delicate and prone to damage, which may provide entry points for HIV.

Receptive anal sex, often called bottoming, poses more risk for contracting HIV than insertive anal sex, or topping.

HIV can also be transmitted during vaginal sex without a condom, although the vaginal lining is not as susceptible to rips and tears as the anus.

The risk of acquiring HIV from oral sex without using a condom or dental dam is very low. It would be possible for HIV to be transmitted if the person giving oral sex has mouth sores or bleeding gums, or if the person receiving oral sex has recently contracted HIV.

In addition to HIV, anal, vaginal, or oral sex without a condom or dental dam can also lead to transmission of other STIs.

Your CD4 cell count is the number of blood cells in a very small blood sample. It is not a count of all the CD4 cells in your body. A higher CD4 count indicates a stronger immune system.

  • The CD4 cell count of a person who does not have HIV can be anything between 500 and 1500.
  • People living with HIV who have a CD4 count over 500 are usually in pretty good health.
  • People living with HIV who have a CD4 cell count below 200 have AIDS and are at high risk of developing serious illnesses.
  • HIV treatment is recommended for all people living with HIV. It is especially important for people with low CD4 counts.

WHAT ARE ANTIBODIES?

Our immune systems develop antibodies in response to all kinds of pathogens. Anytime you get sick or get any kind of infection, your body builds up a defense system and creates antibodies to try and fight that specific infection off. If these antibodies are successful, some infections will go away but the antibodies never do. They will remain in your body, helping to protect you from getting the same infection in the future.

In this way, antibodies allow our bodies to remember a specific infectious agentlike a particular strain of the fluand then respond to it more quickly if exposed to it again in the future. Once we develop antibodies to a virus we may have those antibodies for life or for many years.
