The largest endemic region, in the north-west of the country, covers almost totally the province of Cibitoke and partially the adjoining province of Bubanza. The population at risk is 330,000. The endemic region in the south-west of Burundi covers more than one third of the province of Bururi and has 230,000 people at risk. The smallest endemic region is in the province of Rutana (south-east), where 52,000 people live.</p>
