Fomboni hospital and Nioumachoua district health centre. All
suspected cases were coming from a neighbourhood of Ndrondroni
village with twenty-nine households (estimated population of 125
inhabitants). The team visited 21 households (eight empty at the
time of the survey). The twenty-one households (72.5%) accepted to
participate to the study. Based on the door-to-door survey the au-
thors identified eight cases (the attack rate in the affected area was
