Advanced HIV Disease: A Silent Killer in the Shadows of the HIV Epidemic

Strategic Insights -

In Zimbabwe and sub-Saharan Africa, a new and deadly threat is emerging in the shadow of the HIV epidemic: Advanced HIV Disease (AHD). Despite remarkable progress in the fight against HIV, thousands of lives are still being lost to AHD, a condition linked to late presentation, untreated HIV, or returning to care after long absences. Dr Tich Nyamundanya, a leading health expert from the Zimbabwe Health Interventions, warns that AHD is silently taking lives, even among those on antiretroviral treatment, and is now a more pressing medical challenge than HIV itself.

Key Takeaways:

  • AHD is diagnosed when CD4 cell counts fall below 200 cells per cubic millimetre or when an individual experiences certain clinical symptoms classified under the World Health Organisation (WHO) stage three or four events.
  • In sub-Saharan Africa, more than one in three people living with HIV begin ART already facing AHD, with around 10 percent of them dying within the first three months of treatment.
  • Men are especially vulnerable to AHD, being diagnosed 1.6 times more often than women due to poor health-seeking behaviour, delayed testing, and inconsistent treatment.
  • Children under five years old start ART with severe immune suppression or in WHO stage three or four in 80 percent of cases, putting them at extreme risk if AHD is not diagnosed early and treated promptly.
  • Dr Nyamundanya emphasizes the importance of screening for AHD in individuals who have interrupted treatment for 90 days or more or suspect treatment failure.
  • Screening for TB and cryptococcal meningitis are critical life-saving interventions that can prevent and treat deadly infections if caught early.
