Onderzoeksproduct en/of interventie
All close contacts of 1000 consecutive new leprosy patients in the districts of Nilphamari and Rangpur (Bangladesh) who are recruited for the study are considered for inclusion. A contact group consists of around 20 individuals. A single dose of rifampicin or a placebo is given to all included contacts. The rifampicin comes in capsules of 150 mg and the dosage is the same as recommended in the guidelines of the national leprosy control programme of Bangladesh and DBLM (table). According to bodyweight and age, 2 to 4 capsules are taken by the contact under direct supervision of a DBLM staff member. All the contacts of one patient receive medication from the same container.Table: Dosage of rifampicin according to age and body weightAge/weight .
