Stay negative!

Approach things positively. Don’t forget about condoms and regular HIV tests. 


How to stay HIV-negative?

HIV is a virus attacking and weakening the immune system. You can avoid transmission by following means:

1 500 000

New HIV-infected individuals yearly

38 400 000

HIV-positive people worldwide

4 875

HIV-positive people in the Czech Republic

Where do I get tested?

There are many checkpoints in the Czech Republic where you can get tested anonymously. You'll find contact information at on the interactive map, along with information about whether the testing is anonymous, when to go, whether you need to make an appointment, etc.

The National Institute of Public Health runs the website with the support of The Ministry of Health. Individual places where you can get tested are:

The Czech AIDS Help Society updates information about testing regularly. Have a look at their website.

What’s HIV, and how’s it different from AIDS?

Human Immunodeficiency Virus attacks and weakens the immune system. The late stage of the disease is called Acquired Immune Deficiency Syndrome – when the immunity towards common infections gets poor. An HIV-positive person is one who contracted the virus – not AIDS.

The first HIV (so-called) isolation was from macaques, which had the same AIDS symptoms as humans.

Did you know there are two types of the virus?

It’s HIV-1 and HIV-2, and each comes from different animal species:

  • HIV-1 is predominantly spread worldwide and makes up to 98% of all HIV infections
  • HIV-2 is the 2% left and is prevalent in West Africa.

HIV hides in the cells of the immune system – lymphocytes and macrophages.

How is the virus transmitted?

The virus typically doesn’t survive for long outside the body. There’s a high chance of contracting it from direct contact with the infected person in the acute stage of infection.

The virus can be transmitted via:

  • Sex – in any form (straight, gay, vaginal, oral, anal). The highest risk of contracting it is via anal sex because the mucous membrane in the rectum is more prone to damage; therefore, the sores make it easier for the virus to get to the system.
  • Blood – needles or even shaving equipment. Every blood donor is tested for HIV, so transfusions should no longer spread the disease.
  • From mother to child – in the womb, during birth or breastfeeding. If the woman is not being treated, the risk of transmission is 20%, and it’s only 1% if she regularly takes medication.

You’ll not contract it by “breathing it in”, kissing or holding hands!

High-risk groups

You’ve probably heard that some people are at higher risk of contracting HIV. Such people are:

  • Sex workers and their clients
  • Intravenous drug users
  • Gay men
  • Transgender women

The risk is higher for others when they:

  • Have a deep cut through where the virus can transmit
  • Get a needle prick with a bloody syringe; or when it reaches deeper tissue

What’s AIDS?

It’s a late-stage of HIV infection, and it’s chronic. AIDS stands for:

  • Acquired = not a hereditary condition; the person contracts it
  • Immune = the immune system’s ability to fight bacteria and viruses decreases significantly
  • Deficiency = the immune system can’t function properly
  • Syndrome = set of symptoms

What about prevention?

  • Celibacy
  • Using condoms
  • Regular testing
  • PEP (post-exposure prophylaxis) – is taken after sex, preferably within 72 hours after possible exposure. If the treatment starts within 4 hours after the sex, the risk decreases by 80% after 4 weeks of taking the medication.
  • PrEP (pre-exposure prophylaxis) – is an antiviral medication recommended for people from high-risk groups (multiple sexual partners, anal sex without using a condom or party and play = PnP). The risk can decrease by 99%, but it doesn’t prevent STDs.

Learn to put condom propertly! 

What are the symptoms?

The incubation period is very long – up to 10 months. But only a few days after contracting, the virus spreads in lymph nodes and then, after years, to lymphoid tissues, where it spreads more.

Half of the infected people experience symptoms within 3–8 weeks after infection. The symptoms are nonspecific:

  • Fever
  • Enlarged lymph nodes
  • Sore throat
  • Rash
  • Weight loss
  • Asymptomatic (10–50% of infected people)

Due to the symptoms being nonspecific or the disease being asymptomatic, it’s hard to diagnose HIV without a test. The immunity gets weaker, and the system has trouble fighting against common and serious infections over time. Affected people are also at higher risk of tumour development.

Serious infections include:

  • Type B and C hepatitis
  • Tuberculosis
  • Pneumonia

When or how to get tested?

The testing should take place 2–3 months after high-risk sexual behaviour. The person should act responsibly during this period – wear condoms or practice celibacy.

Every individual from the high-risk group should get tested regularly. You can get it done even before entering a serious relationship – preferably both of you.

How is it done?

  • Rapid test → result in 30 minutes
  • Blood test → result in several days
  • Self-test kit → sent to a laboratory after

You can get tested anonymously in the Dům světla’s checkpoints.

If the test comes back positive, you’ll have to retake it. The same goes for when the result is indeterminate.

There’s a low probability of being HIV-positive if the results come back negative, and one should get tested again after participating in risky sexual behaviour.

A negative result doesn’t mean the person can’t contract it in the future. 

What’s the treatment?

HIV is a virus, so antibiotics fighting bacterial infections won’t help. The treatment lies in antiviral medications. Usually, three types of these are combined, and the treatment is lifelong. The goal is to reduce the viral load in the blood, which then lowers to a level where it’s no longer detectable and transmittable from person to person.

HIV and AIDS in numbers

  • AIDS was identified in France in 1982
  • The connection between HIV and AIDS was discovered during 1983–1984.
  • Around 37 million people worldwide live with HIV.
  • Approximately 1,8 million people get infected yearly.
  • In 2020, there were 251 cases in the Czech Republic.
  • HIV-positive people in the Czech Republic in 2019: 3,590 (2,378 men and 380 women); 18,8 % had AIDS.
  • The first HIV isolation came from macaques that had the same symptoms as humans with AIDS.
