Tuberculosis and the HIV epidemic : Increasing annual risk of tuberculous infection in Kenya, 1986-1996.
The purpose of this study was to assess the impact of the Indreased incidence of tuberculosis (TB) due to HIV infection on the risk of TB infection in schoolchildren Methods.
Tuberculin surveys were earried out in randomly selected prithiry schools in 12 districts in Kenya during 1986 through 1990 and 1994 through 1996.
Distriets were grouped mccording to the year in which TB notification rates started to increase, HIV prevalence in TB patients and clunges In TB infection prevalence were coin-pared between districts.
Tubere shous infection prevalence rates increases strongry in diftrients where TB notification rates had increased before 1994 (odds ratio=3.1. 96% confidence inferval=2,3,4.1) but did not increase in districts where notification more recently of not in all.
HIV prevalence rates in TB patients were 50% in districts with an earfly in nodification rates 8% in the other study districts. and 28% in the other study districts.
Countrics with an increasing prevalence of HIV infection will feed additional resources for TB contail, not only for current patients but also for the patients in additional. cases arising from the increased risk of TB infection.
