A prospective (sero-)epidemiological study on contact transmission and chemoprophylaxis in leprosy.

Completed

Primary Outcome Measures
NameTimeMethod
The primary outcome measure is the number of new leprosy patients emerging from the contact groups. The proportions between the rifampicin and the placebo group will be compared at 2-years intervals.
Secondary Outcome Measures
NameTimeMethod
Analysis will be carried out in order to define special groups at risk. The results of the serological tests will also be compiled and analysed. The number of leprosy patients found in the referent group will be used to calculate the prevalence rate (at intake) and the incidence rate (during follow-up) in the general population, allowing for calculation of relative risks among the contacts.
