HIV test

Professionally updated: May 30, 2024

HIV, or human immunodeficiency virus, is a virus that affects the body's immune system, making you more susceptible to infections and certain types of cancer. Without treatment, HIV can progress to AIDS, a serious and life-threatening condition. Fortunately, many effective treatments have been developed that allow many people with HIV to live long, healthy lives.

What is HIV?

HIV is a virus that attacks the body's immune system. Specifically, it attacks CD4 cells (T cells). When HIV targets these cells, the body becomes more vulnerable and may have a harder time fighting disease and become more susceptible to infections and certain types of cancer.

Without treatment, HIV can progress to AIDS, a serious and life-threatening condition. Fortunately, many effective treatments have become available, allowing many people with HIV to live long, healthy lives.

HIV symptoms

After being infected with HIV, various symptoms can occur. Early signs can include flu-like symptoms such as fever, headache and rash. In some cases, HIV doesn't show any symptoms until the later stages. Therefore, regular screening is essential, especially if you belong to a high-risk group.

Early symptoms of HIV

  • Headaches
  • Sore throat
  • Fever
  • Rashes
  • Lack of desire for food
  • Swollen lymph nodes
  • Sore muscles and joints.

Late symptoms of HIV

  • Headaches
  • Fever
  • Coughs
  • Shortness of breath
  • Swallowing pain
  • Diarrhea
  • Weight loss
  • Poor general condition
  • Vision problems
  • Nausea
  • Vomiting
  • Abdominal pain.

How do you get HIV?

HIV is primarily transmitted through unprotected sex, infected blood products or from mother to child during pregnancy, birth or breastfeeding. Over 90% of transmission occurs through sexual contact. HIV can also be transmitted by sharing needles or syringes with an infected person.

Understanding how the virus is transmitted is crucial to effectively protect against infection. Early diagnosis and treatment are key to living well with HIV.

How is HIV transmitted?

HIV is primarily transmitted through contact with infected blood, semen, vaginal fluid or breast milk. The most common routes of transmission include:

  • Unprotected intercourse with an infected partner
  • Sharing needles or syringes with an infected person
  • Mother to child transfer during pregnancy, birth or breastfeeding
  • Blood transfusions with infected blood (although this is rare in countries with modern medical systems).

What is the difference between HIV and AIDS?

HIV and AIDS are related, but not the same. HIV is the virus that causes the infection, while AIDS is the most severe stage of HIV infection. AIDS is diagnosed when a person with HIV develops certain infections or when the CD4 cell count drops to a very low level.

When the number of CD4 cells in the blood decreases, you become more susceptible to infections and cancers that would normally be fought off by a healthy immune system. If you develop one of these diseases in addition to the HIV infection itself, you have developed AIDS.

With effective treatment, many people with HIV can live long lives without developing AIDS.

How many people have HIV in Denmark?

In Denmark, around 6,800 people are living with HIV. In recent years, there has been a decrease in the number of people diagnosed with HIV. This indicates that the HIV curve has broken and that we can become one of the first countries without new HIV cases.

Thanks to advanced medical treatments, most of these people have a good quality of life and can live a long and healthy life. However, it is important to diagnose and treat HIV early for the best results.

Facts about HIV

  • HIV stands for Human Immunodeficiency Virus and is a virus that attacks the immune system.
  • The most common cause of HIV infection is unprotected sexual contact with someone who is HIV-positive.
  • It is possible to live with HIV for many years before the disease progresses to AIDS.
  • Modern HIV treatment can effectively control the virus and allow most HIV-positive people to live without symptoms for a long time.
  • The unreported number of HIV-infected people is around 500. Half of them are men who have sex with men.
  • There are relatively few AIDS diagnoses in Denmark. This is due to the effective medical treatment available for HIV.

What is an HIV test?

An HIV test is the only sure way to know if you have HIV. The test is quick, painless and anonymous. The test works by detecting the presence of HIV antibodies or virus particles in the blood.

Regular testing is recommended if you are sexually active and have changing partners or if you are in any other risk group. Early diagnosis provides access to treatment that can prevent the virus from progressing to AIDS.

How an HIV test works

Blood test

A small amount of blood is taken from a finger prick or vein in the arm.

Antibody and antigen tests

The test looks for antibodies (immune system response) and antigens (viral proteins) in the blood.

Laboratory testing

The blood sample is sent to a laboratory for more detailed analysis. Results may take a few days to get.

Treatment of HIV

HIV cannot be cured, but it can be effectively controlled with antiretroviral therapy (ART), which helps keep the virus in check and protects the immune system. Treatment with ART also makes it less likely to transmit the virus to others.

It is important for people living with HIV to follow their treatment plan carefully and take the medication as prescribed by their doctor. Regular doctor visits and tests are also part of treatment to monitor the effects of treatment and assess any side effects.

While ART does not cure HIV, it has revolutionized the treatment of the disease, transforming it from a potentially fatal condition to a chronic, manageable disease for many people.

HIV prevention and protection

Prevention is a crucial component in the fight against HIV. This includes using condoms during sex, regular HIV testing and, in some cases, preventative medication like PrEP. Get informed about how you can protect yourself and others and talk to your doctor about the different prevention options.

Protect yourself against HIV

Use of condoms

Proper and consistent use of condoms during sexual intercourse can significantly reduce the risk of HIV transmission.

PrEP (Pre-exposure prophylaxis)

PrEP is a medication that can be taken by people at high risk of HIV infection to prevent transmission.

Treatment as prevention (TasP)

Treating HIV-positive people with antiretroviral therapy (ART) can reduce their viral load so much that the risk of transmission to a sexual partner becomes minimal.

Avoid risky behavior

Avoid risky behaviors like unprotected sex with unknown partners or sharing needles.

Testing

Regular screening and testing for HIV is important, especially for those who are sexually active or exposed to other risk factors.

How is HIV transmitted?

HIV is primarily transmitted through unprotected sex with an infected person, the use of infected needles or syringes, and from mother to child during pregnancy, birth or breastfeeding. Transmission via blood transfusion with infected blood is very rare in countries where blood is routinely tested for HIV.

How is HIV treated?

Although there is no cure for HIV, medication (antiretroviral therapy - ART) can control the virus and prevent it from progressing to AIDS. ART also helps reduce the risk of transmitting the virus to others.

What should I do if I think I have HIV?

If you have symptoms of HIV or think you may have been exposed to the virus, you should get tested immediately. The test is quick and anonymous. If the test is positive, you will be referred to a specialist who will help you start treatment as soon as possible.

Can I live a normal life with HIV?

Yes, with early diagnosis and proper treatment, people with HIV can live a long and healthy life. It's crucial to follow the prescribed medication plan closely and continue with regular doctor visits and tests to monitor your health.
