General and HIV-1-associated morbidity in a rural Ugandan community.
OBJECTIVE
The AIDS epidemic in sub-Saharan Africa affects whole communities, adding to the already high burden of morbidity. Reports of AIDS cases are usually from hospital attenders, often diagnosed using the World Health Organization (WHO) clinical case definition. Little is known about the extent of HIV-associated morbidity in the general population. The objectives of this study were to describe the prevalence of (1) markers of general morbidity and (2) the criteria of the WHO clinical case definition for AIDS and (3) to determine the association between these markers and HIV-1 serostatus in a rural Ugandan community.


METHODS
A survey was conducted among the adult population (aged > or = 13 years) of 15 neighbouring villages in Masaka District, south-west Uganda. The survey included medical history, physical examination and testing for HIV-1 antibodies.


RESULTS
The HIV-1 seroprevalence among 4175 out of 5278 (79%) eligible adults was 8.2%. Current health problems were reported by 57.6% of adults, with increased rates in HIV-1-positive subjects, women and older people. Five of the 10 most common complaints showed significant associations with HIV-1 status, as did reported genital ulcer and vaginal discharge. The crude HIV-1 attributable disease burden in the population was 1.2% for current illness, 4.3% for previous serious illness and 9.9% for illness leading to hospital admission. Overall, 11 (3.3%) of the HIV-1-positive and nine (0.2%) of the HIV-1-negative subjects had AIDS as defined by the clinical case definition. The positive and negative predictive values and specificity were 55.0, 92.0%, and 99.8%, respectively.


CONCLUSIONS
Against a background of high general morbidity, we observed a relatively small population attribution of HIV-1-associated morbidity. The results indicate that the clinical AIDS case definition may provide a useful tool for population surveys.
