HIV

Should you get HIV tested?

In 2020, approximately 37.7 million people across the globe were HIV positive. This includes 36 million adults and 1.7 million children aged between 0-14. More than half were women and girls. South Africa has the largest HIV epidemic.

If you are 13 to 64 years old and don’t fall into a higher risk category for human immunodeficiency virus (HIV), you should still get a test at least once as part of your routine health check-up.

According to the Centers for Disease Control and Prevention (CDC), sexually active people (even those in a monogamous relationship) should rule out the possibility of infection with regular testing.

Knowledge is far better than not knowing

The CDC recommends that people in the following higher-risk categories should get a test for HIV more than once a year:

  • Have multiple sexual partners with undisclosed sexual histories
  • Have unprotected sex with a partner who has HIV
  • Share needles, syringes or other injection equipment to inject drugs
  • Being diagnosed and on medication for specific conditions such as hepatitis, tuberculosis and sexually transmitted infections.

Most importantly, pregnant women should be tested as part of pregnancy care. Should you be HIV positive, treatment with antiretroviral therapy (ART) starts immediately to protect your unborn baby from infection. The sooner a woman starts on ART, the lower the risk – as low as 1 percent – of mother to child transmission of HIV.

 

High-risk region

According to UNAIDS 2019 statistics, about 7.7 million South Africans live with HIV / AIDS. The country has the biggest and most high profile HIV epidemic with the biggest antiretroviral treatment (ART) programme in the world. 

Thus HIV testing is critical in preventing the spread of the disease amongst the population. In 2018, of the 20 per cent of the people living with HIV, 90 per cent were aware of their status, and 68 per cent were accessing ART. 

Knowing your status protects yourself and others and is proving to be an effective prevention tool.  

However, in a country with the highest incidence of rape and sexual assault in the world, if you’ve had high-risk exposure because of rape or sexual assault, been stabbed, or you had unprotected sex with someone who is HIV positive, then you can access treatment immediately.

This is what you should do after high-risk exposure:

  • Report sexual assault or rape or a stabbing, even if it is just a scratch, to the police immediately. A district surgeon will examine you.
  • Call your doctor or report to an emergency room immediately if you have had sex with someone HIV positive.
  • You will be tested for confirmation that you don’t have HIV before receiving emergency medication, post-exposure prophylaxis (PEP) 
  • PEPs are for preventing infection, and the 28-day course of treatment is most effective if it begins within 72 hours of exposure.
  • Follow up tests.
  • Early detection is crucial, without which you may run the risk of infecting others or miss out on early treatment. Even if you miss the 72 hour window period post-exposure, get tested a few weeks afterwards. 

Time to test

If you test too soon, you may get a faulty result if the immune system hasn’t kicked in yet to create antibodies to fight the infection. No test can pick up a positive result just after infection. 

And if you delay testing and unknowingly continue having unprotected sex, you may run the risk of infecting others. 

According to the Nelson Mandela University, these are the most common tests available:  

  • ELISA – Enzyme-linked Immunosorbent Assay checks for antibodies as soon as three weeks after infection. They draw blood from a vein and sent to a laboratory for analysis. The results are usually available within a week.
  • Rapid tests checks for antibodies. The Rapid Test uses blood from a finger prick, and results are available within 30 minutes. This is the most common test, done 3 to 6 weeks after exposure.
  • Self-tests are rapid tests.  A swab collects saliva from your mouth, or blood from a finger prick. This test picks up levels of antibodies after three months, much later than lab tests or the Rapid Test done at a clinic. You may get a negative result if you test a month or two months after infection.
  • P22 Antigen Detection checks for the virus. This method can detect the virus a few weeks after infection. The test looks for antigens – antibodies and proteins from HIV in your blood. A less expensive ELISA antibody test provides the same results. 
  • PCR Antigen Detection checks for the virus. Within three weeks after infection, this test can pick up small quantities of HIV in the blood. This is an expensive, highly sophisticated test; not suitable for mass testing. 

If you tested negative, this might not be accurate, so it is best to do a follow-up test to clear up uncertainties.
