How Long Does Hiv Take To Show Up After Exposure

How Long Are The Window Periods Of Different Hiv Tests

It is hard to say exactly how long the window period lasts, as there are variations between individuals and it is a difficult topic to research .

Nonetheless, a study by Dr Kevin Delaney and colleagues calculated window periods for a range of HIV testing assays. All these analyses were based on plasma samples. Window periods are likely to be several days longer when testing samples of fingerprick blood or of oral fluid, as will be normal when using rapid, point-of-care tests and self-testing devices. Unfortunately, precise figures for how much longer the window periods are have not yet been published.

The researchers analysis confirms that fourth-generation laboratory tests detect HIV infections between one and three weeks earlier than older antibody-only tests. Moreover, their data suggest that some countries guidelines which recommend retesting 90 days after a possible exposure to HIV are more cautious than they need to be.

Afourth-generation laboratory testis recommended in UK and US guidelines. It uses a sample of blood plasma or serum and can detect immunoglobulin G antibodies, immunoglobulin M antibodies and p24 viral antigen . Commonly used tests of this type include Abbott Architect HIV Ag/Ab, GS Combo Ag/Ab EIA and Siemens Combo HIV Ag-Ab.

• The median window period is 18 days . This indicates that half of all infections would be detected between 13 and 24 days after exposure.

• 99% of HIV-infected individuals would be detectable within 44 days of exposure.

How Much Do Hiv Tests Cost

Unlike rapid tests, blood tests for HIV are covered by Medicare, which means your doctor can order the test free of charge for you.

If you are not eligible for Medicare, you may also be able to claim some of the testing costs through private health insurance. Check with your provider to see if youre eligible.

What Can I Expect If I Have Hiv

If youre diagnosed with HIV, its important to know that those living with HIV who follow treatment guidelines can live full lives for nearly as long as those without HIV.

If you have a high CD4 count and an undetectable viral load within a year of starting treatment, research suggests youll have the best outcomes, as long as you continue your treatment plan.

You can improve your outlook by:

• Getting tested as part of routine healthcare or if you think youve been exposed.
• Starting ART soon after being diagnosed.
• Taking your medicine every day.
• Keeping your appointments with your healthcare team.

ART can keep blood levels undetectable but cant entirely rid your body of the virus . If you dont take your medication every day, the virus can start multiplying again and mutate, which may cause your medications to stop working.

Left untreated, it can take about 10 years for HIV to advance to AIDS. If you progress to AIDS and it goes untreated, you can expect to live about three years more.

For those on treatment, if you have a high CD4 count and undetectable viral load within a year of starting treatment, you can expect to live about as long as someone without HIV. If you have a low CD4 count or a detectable viral load within a year of starting treatment, you may live 10 to 20 years less than someone without HIV.

What Should I Do If I Think I Could Have Hiv

Only an HIV test can tell you whether you have HIV.

Try not to guess based on any symptoms you may or may not have, or on the HIV status of a person you have had sex with.

If you test, tell whoever tests you if youve recently taken risks or had symptoms similar to seroconversion illness, as this will affect the kind of HIV test you should have.

To be on the safe side, and until you know your test result, use condoms to protect anyone you have sex with.

What Are The Factors That Affect Disease Progression

The most important factor affecting HIV progression is the ability to achieve viral suppression. Taking antiretroviral therapy regularly helps many people slow the progression of HIV and reach viral suppression.

However, a variety of factors affect HIV progression, and some people progress through the phases of HIV more quickly than others.

Factors that affect HIV progression can include:

• Ability to achieve viral suppression. Whether someone can take their antiretroviral medications and achieve viral suppression is the most important factor by far.
• Age when symptoms start. Being older can result in faster progression of HIV.
• Health before treatment. If a person had other diseases, such as tuberculosis, hepatitis C, or other sexually transmitted diseases , it can affect their overall health.
• Timing of diagnosis. Another important factor is how soon a person was diagnosed after they contracted HIV. The longer between their diagnosis and treatment, the more time the disease has to progress unchecked.
• Lifestyle. Practicing an unhealthy lifestyle, such as having a poor diet and experiencing severe stress, can cause HIV to progress more quickly.
• Genetic history. Some people seem to progress more quickly through their disease given their genetic makeup.

Some factors can delay or slow the progression of HIV. These include:

Living a healthy lifestyle and seeing a healthcare provider regularly can make a big difference in a persons overall health.

Hiv Stigma And Discrimination

HIV can prompt intense feelings in people, regardless of their HIV status. It is sometimes viewed with a sense of unacceptability or disgrace. A person with HIV may feel shame and despair about their status. An HIV-negative person may be fearful or angry when they discover someone has HIV. The relationship of these feelings to HIV is referred to as stigma.Felt stigma refers to deep feelings of shame and self-loathing, and the expectation of discrimination. It can have serious negative impacts on the health and wellbeing of people living with HIV by discouraging them from getting tested, receiving support, or taking treatment. It may also lead people to engage in high-risk behaviours that harm their health, and contribute to new HIV infections.Enacted stigma is the experience of unfair treatment by others. For people living with HIV this can be in the form of being treated differently and poorly, or through rejection, abuse, or discrimination.HIV stigma is particularly harmful when it overlaps with other factors that are stigmatised such as if a person uses drugs, is a sex worker, is trans or gender diverse.Breaking down stigma is a community response where:

If you have experienced stigma or discrimination from a health care provider, and are unable to resolve your complaint with them directly, contact the Health Complaints Commissioner

Does Pep Cause Side Effects

PEP is safe, but the HIV medicines used for PEP may cause side effects like nausea in some people. In almost all cases, these side effects can be treated and arent life-threatening.

If you are taking PEP, talk to your health care provider if you have any side effect that bothers you or that does not go away.

PEP medicines may also interact with other medicines that a person is taking . For this reason, its important to tell your health care provider about any other medicines that you take.

Stage : The Asymptomatic Stage

Once a person has been through the acute primary infection stage and seroconversion process, they can often start to feel better. In fact, HIV may not cause any other symptoms for up to 10 or even 15 years .

However, the virus will still be active, infecting new cells and making copies of itself. HIV can still be passed on during this stage. If left untreated, over time, HIV infection will cause severe damage to the immune system.

Getting Your Hiv Test Results

Most HIV test results are available within a week.

If the test result is negative, you may receive your results within a few days.

If the initial test result is positive, then additional testing to confirm the result needs to be performed in a reference laboratory and this can take up to a week to get a result.

Is It Safe For Children With Hiv To Receive Routine Immunizations

• MMR, or measles, mumps, and rubella vaccine, is safe to give to children with HIV, unless they have a severely weakened immune system.

• DTaP/Td vaccine is safe to give to infants and children with HIV.

• Hib and Hep B vaccines are safe to give to children with HIV.

• Hepatitis A and B vaccines are safe to give to HIV-positive children.

• VZIG should be considered for known HIV-positive children, depending on their immune status.

• A yearly influenza vaccine is recommended for children with HIV, as well as any individual living in the same household as a child with HIV. There are two types of influenza vaccine children and adults with HIV should receive the “shot” form of the vaccine–not the nasal spray form, as it contains a live virus. Pneumococcal vaccine can be safely administered to age-appropriate HIV-infected children.

Always consult with your child’s doctor regarding immunizations for an HIV-infected child.

The Third Stage Of Hiv: Early Symptomatic Disease

During this, the third stage of infection, your immune system is engaged in a constant battle with the rapidly replicating virus. Approximately 50 million to 2 billion new virus particles are created each day. The immune system responds by replenishing the peripheral blood with up to 2 billion new CD4 cells per day.

The immune system can hold HIV in check for many years, but will eventually begin to lose the battle. The virus begins to destroy the CD4 cell population. As that happens, the CD4 counts continue to drop, and signs and symptoms more specific to HIV/AIDS arise.

These signs and symptoms are:

• Persistent generalised lymphadenopathy .
• Thrombocytopenia .
• Early stages of neurological disease .

How Do I Take Care Of Myself With Hiv

The best way to take care of yourself while living with HIV is to follow your treatment plan.

• Make sure to take your medications as prescribed and on time.
• Show up to all appointments so your healthcare team can monitor how youre feeling and know if theres a need to adjust your treatment.
• Follow your healthcare providers recommendations on how to avoid additional illnesses.

What Happens If My Test Is Positive

If you test positive for HIV, it is important to remember that with treatment you can live a long, healthy life. In fact, with early treatment, people with HIV can live about as long as people that are not infected.

A team approach will help you get the medical care and support that you need. Start by talking to your doctor or the counselor or social worker at the testing site. He or she can help you with suggestions on how to talk to your parents or guardians and how to find a health care provider whos an HIV specialist. By starting treatment as soon as possible, you can stay healthy and learn to live well with HIV.

Hiv Testing In A Health Care Setting Or Lab

If you take a test in a health care setting or a lab, a health care provider or lab technician will take a sample of your blood or oral fluid. If its a rapid test , you may be able to wait for the results, but if its a laboratory test, it can take several days for your results to be available. Your health care provider or counselor may talk with you about your risk factors, answer any questions you might have, and discuss next steps with you, especially if your rapid test result is positive.

• If the test comes back negative, and you havent had an exposure during the window period for the test you took, you can be confident you dont have HIV.
• If your HIV test result is positive, the lab will conduct follow-up testing, usually on the same sample as the first.

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.

The First Stage Of Hiv: Acute Infection

Acute infection can occur through exposure to the bodily fluids of an infected person. Any behaviour that involves you being or becoming exposed to someone elses bodily fluids carries a risk of infection.

The most common methods of HIV transmission are unprotected sexual activity and the sharing of needles, especially by drug users. Additionally, HIV-positive pregnant women, women in labour and those breastfeeding their babies are also able to infect their children.

How To Stay Healthy

The best way to prevent complications from HIV is to take medication consistently as prescribed, and to start treatment as soon as possible.

Antiretroviral therapy keeps the immune system healthy and, when taken consistently so that the level of HIV virus in the blood is undetectable, reduces the risk of transmitting the virus to others to zero.

The following lifestyle habits may also help people with HIV stay healthy:

• Eating a balanced diet, full of fresh fruits and vegetables, whole grains, and lean protein sources.
• Avoiding raw meat, seafood, eggs, and unpasteurized dairy products, as they may increase the risk of food poisoning.
• Preparing and storing food in a hygienic manner.
• Not drinking water directly from lakes or rivers.
• When abroad, drinking bottled water and avoiding ice and foods that may be a source of infection, such as raw meat or peeled fruits and vegetables.
• Always using condoms and other barrier methods when having sex to avoid getting other STIs.
• Never sharing needles or syringes with anyone else.
• Avoiding people who have contagious infections.
• Avoiding some supplements, such as St. Johns wort and garlic supplements, which may interfere with antiretroviral medications.
• Practicing good hygiene around pets, especially cats, and their feces. Wear gloves when changing litter trays and wash hands thoroughly afterward.
• Asking a doctor about vaccinations to help prevent pneumonia and other serious infections.

People Unaware Of Having Hiv

Its estimated that about 1 in 7 people living with HIV in the United States dont know they have the virus.

People who are unaware that they have HIV are less likely to take precautions to avoid transmission to other people. They also likely dont take medications to suppress the virus.

If you dont currently have HIV, you can prevent your chances of infection by:

• discussing HIV and STIs with your partner before engaging in sexual activity
• using a barrier method every time you engage in sexual activity
• avoiding sharing needles
• talking with your doctor about postexposure prophylaxis if you may have been exposed to HIV in the past 72 hours
• getting tested for other STIs regularly or before engaging in sexual activity with a new partner

If you do have HIV, you can prevent transmitting it to others by:

• discussing HIV and STIs with your partner before engaging in sexual activity
• using a barrier method every time you engage in sexual activity
• taking your medications as prescribed
• avoiding sharing needles or drug injection equipment
• having your viral load tested regularly as recommended by your doctor

What Can Effective Hiv Treatment Do

HIV medication keeps you healthy so you can live a normal lifespan.

Treatment can also reduce your viral load to undetectable levels so that you wont be able to pass on HIV to anyone else. It can take up to six months from starting treatment to become undetectable, so its important to test and start treatment on time.
