South Africa: A Fungal Infection That Targets the Brain Claims Many Lives in SA, Stopping It Won't Be Easy

What the report says

South Africa’s Spotlight, published by AllAfrica from Cape Town on 14 September 2026, reports that cryptococcal meningitis remains one of the most deadly opportunistic infections affecting people living with HIV. The fungal disease attacks the lining of the brain and is described by clinicians as a major but often overlooked cause of HIV-related deaths in the country. The article notes that tuberculosis remains the leading HIV-related killer, while cryptococcal meningitis is commonly estimated as the second biggest contributor.

The briefing explains that the fungi involved are widespread in the environment and are usually harmless to healthy people, but can become dangerous when the immune system is weakened. It focuses especially on people with advanced HIV, including those with very low CD4 counts, while also noting that transplant recipients, cancer patients and people taking steroids can be at risk. In South Africa, the piece says, hundreds of thousands of people may fall into the highest-risk group.

A key prevention strategy is early screening with a cryptococcal antigen test, which can identify infection before it reaches the brain. At that stage, treatment with fluconazole can help stop progression. Once meningitis develops, however, treatment becomes much harder and hospital care is needed to manage severe inflammation and high pressure in the skull.

The article says the disease’s high early mortality and persistent burden point to gaps in HIV care, especially for people who do not get tested or treated soon enough. It adds that cryptococcal meningitis has remained under the radar for years despite its impact on preventable deaths.
