Twelve months fixed duration WHO multidrug therapy for multibacillary leprosy: incidence of relapses in Agra field based cohort study

The reported low relapse rates after 24 months multidrug therapy (MDT) for multibacillary leprosy (MB) led to the recommendation of reducing duration of therapy to 12 months. However, only a few reports exist on long term follow up data after 12 months fixed duration therapy (FDT). The present study was done to assess the incidence of relapse in MB leprosy patients after 12 months treatment.
