What was discovered

Clinical description in Rakai, on Lake Victoria, of a wasting and chronic diarrhoea illness that locals called 'slim' and that was linked to HIV in 1985. It is the first description of AIDS in sub-Saharan Africa.

The name 'slim' was recorded in 1982-83; Serwadda and colleagues' article in The Lancet appeared in 1985. Cases in Zaire and Zambia were described almost simultaneously, complicating priority.

What it led to

  • recognition of HIV as a pandemic in East Africa
  • the Rakai Project, a long-running population cohort
  • prevention strategies such as circumcision and suppressive therapy
