At focus of urinary bilharziasis of Khemis El Khechna, non inspected since 1966, the urines of 1000 children were investigated. Eggs of Schistosoma haematobium, alive for the most part, were found in 78 samples (7.8%). The authors point out the dangers of the persistence and the possible spreading of this focus.
