OBJECTIVE: This study was designed to determine the incubation period
and risks for development of HIV-1 related disease in a population of
women with a known time of seroconversion. METHOD: A cohort of 163 women
were enrolled at the time of seroconversion and followed for the
occurrence of HIV-1 related illness at 6 months intervals for 12-60
months following seroconversion. Survival analysis were performed. HIV-1
related disease was classified using the CDC staging system. Lymphocyte
subset determination were performed by flow cytometry. RESULTS: Of the
163 women identified 68 have developed stage 4A disease while 57 have
developed stage 4C disease. The median time to development of stage 4A
was 47.3 months with a mean time of 67.2 months. The median time to
development of stage 4C disease was 51.1 months with a mean time of 86.3
months. Lymphocyte subset determination showed a close correlation
between clinical staging and absolute CD4 counts. CONCLUSION: The
incubation time to symptomatic disease is much shorter in this cohort of
women as compared to other studies. This may have profound impacts on
the course of the HIV epidemic in Africa.
