HIV in South Africa: Know Your Status, Change the Story

8.2 million South Africans live with HIV. With treatment from your doctor, people with HIV live long, healthy lives and cannot transmit the virus sexually. That fact changes everything. But it starts with testing.

The most important fact about HIV in 2026

Undetectable = Untransmittable

When a person living with HIV takes their treatment consistently and maintains an undetectable viral load, they cannot sexually transmit HIV to their partners. This is not theory. It is backed by the PARTNER, PARTNER2, and HPTN 052 studies involving tens of thousands of couples. Zero transmissions from partners with undetectable viral loads.

What U=U means for you: If you test positive, treatment from your doctor can suppress the virus to undetectable levels. You can have a healthy sex life, have children, and live a normal lifespan. Testing is the gateway to all of this.

What to look for

Does HIV have symptoms?

HIV is often called "the great imitator" because early symptoms mimic the flu and then disappear completely. Most people living with HIV feel perfectly healthy for years. The only way to know is to test.

Acute HIV (2-4 weeks after infection): Flu-like symptoms in some people: fever, sore throat, rash, swollen lymph nodes, fatigue, muscle aches. These resolve on their own within 1-2 weeks and are often dismissed as a common cold or flu.
Clinical latency (months to years): The virus is active but reproducing at low levels. No symptoms at all. You feel healthy. You look healthy. But you can transmit the virus. This stage can last a decade or more without treatment.
Without treatment (8-10 years): The immune system weakens progressively. Opportunistic infections begin: persistent fevers, chronic diarrhoea, rapid weight loss, recurrent infections, certain cancers. This late stage is called AIDS. With treatment, this stage is completely preventable.
"
"The patients I worry about most are the ones who have never tested. People on treatment do brilliantly. They live normal lives. They cannot transmit the virus. The only barrier is that first test. And at R168, there is no reason not to know your status."
Dr. Samantha Naidoo, MB ChB, FCP (SA), Medical Director, Epicentre

Without treatment

What happens if HIV goes untreated?

Untreated HIV follows a predictable path over 8-10 years. Treatment at any stage can halt and reverse this progression.

1
Weeks 2-4: Acute infection
Flu-like symptoms in some people. Very high viral load, very contagious. Symptoms resolve in 1-2 weeks. Most people do not realise they have been infected.
2
Months to years: Clinical latency
No symptoms. The virus slowly destroys CD4 cells. You feel healthy. Without treatment, this stage lasts 8-10 years on average. You remain contagious throughout.
3
CD4 drops below 200: AIDS
The immune system can no longer fight infections. Opportunistic infections include TB, pneumonia, certain cancers (Kaposi's sarcoma, lymphoma), chronic diarrhoea, and rapid weight loss. Without treatment, life expectancy after AIDS diagnosis is approximately 3 years.
With treatment: a normal lifespan
Treatment prescribed by your doctor suppresses the virus to undetectable levels. CD4 cells recover. Immune function returns. Life expectancy approaches that of someone without HIV. U=U applies.

Prevention

Can HIV be prevented?

Yes. Beyond condoms, there are medical prevention tools available from your GP or public clinic. Epicentre provides the testing; your doctor provides the prevention.

PrEP (pre-exposure prophylaxis): A daily pill taken by HIV-negative people to prevent infection. Over 99% effective when taken consistently. Available from your GP, public clinics, or organisations like Anova Health. Epicentre does not prescribe PrEP but can test your HIV status before you start.
PEP (post-exposure prophylaxis): Emergency treatment started within 72 hours of a potential HIV exposure (unprotected sex, needle stick, sexual assault). Available at public hospital emergency departments. Time-sensitive. Epicentre does not provide PEP but can test your status afterwards.
Other STIs increase HIV risk significantly. Having untreated gonorrhoea, chlamydia, syphilis, or herpes makes you 2-10 times more likely to contract or transmit HIV. Testing and treating other STIs is also an HIV prevention strategy. View all STI packages →

Get tested

Where can I get an HIV test in South Africa without a referral?

Epicentre uses 4th-generation ELISA testing, which detects both HIV antibodies and p24 antigen. This catches HIV earlier than standard antibody-only tests. Testing window: 2-4 weeks after exposure. Conclusive at 3 months.

HIV Screening

Express STI (5-in-1 blood panel)

R1,076🎓 R968

HIV + syphilis + chlamydia Ab + hepatitis B + herpes IgM. Fastest results: 24hr urgent available.

4× R269/mo with Payflex

Medium PCR + HIV (9 pathogens + HIV)

R1,508+

Add HIV screening to any PCR package. Ask at the lab or when booking online. Covers all common STIs plus HIV.

Anonymous and confidential. Results go to a password-protected portal only you can access. You can test under a pseudonym. No notification to medical aids unless you request it. LGBTQIA+ inclusive. We are here to test, not to judge.

FAQ

HIV: Your Questions Answered

What does U=U mean?

Undetectable = Untransmittable. A person on treatment with an undetectable viral load cannot sexually transmit HIV. This is proven by multiple large clinical trials involving tens of thousands of couples with zero transmissions.

How soon after exposure can I test?

2-4 weeks with Epicentre's 4th-gen ELISA (detects antibodies + p24 antigen). A negative test at 3 months is considered conclusive. Rapid antibody-only tests need longer.

Is HIV curable?

Not yet. But treatment prescribed by your doctor suppresses the virus to undetectable levels. People on treatment live normal lifespans, have healthy relationships, and cannot transmit HIV sexually.

Can I get PrEP or PEP from Epicentre?

No. Epicentre provides HIV testing, not treatment or prevention prescriptions. PrEP and PEP are available from your GP, public clinics, or organisations like Anova Health. We can test your HIV status before you start PrEP or after completing PEP.

Do other STIs affect HIV risk?

Yes, significantly. Untreated gonorrhoea, chlamydia, syphilis, or herpes make you 2-10× more likely to contract or transmit HIV. Testing for and treating other STIs is also an HIV prevention strategy. View all STI packages →

Is the test confidential?

Completely. Password-protected portal. Anonymous testing available (use a pseudonym). No medical aid notification unless you request it. LGBTQIA+ inclusive.

How much does HIV testing cost?

HIV Screening: R168. Express STI (includes HIV): R1,076. Add HIV to any PCR package on request. Students 10% off. Payflex 4× interest-free. View all packages →
