title: [Delayed home screening of leprosy; experience of the screening team in Mayotte].
abstract: Mayotte, a French territory island located in the Indian Ocean near Madagascar, remains a leprosy endemic area. In 2006, leprosy was still a problem of public health with a prevalence of 3.94 per 10,000 inhabitants. There is practically no formal consensus about active screening (AS) on an index case. According to teams and their related staffs, the AS concerns intradomicilary contact individuals (IDC) restrictively or extended to extra-domicilary social and professional contacts. Date, number and frequency of these investigations depend on each team. Between 1997 and 2003, there was no AS planned in Mayotte, but all index case individuals have been encouraged to propose a screening to their relatives through specific campaign information and education. This procedure allowed to identify 10 new cases of leprosy infection among the IDC. Concurrently 12 IDC cases have been diagnosed by health workers. In 2003, we performed a postponed AS within IDC of every Mahorais case registered by passive detection between 1997 and 2003. 325 IDC have been examined and 15 new cases have been detected. All these new cases showed early leprosy features: 14 were paucibacillary forms, among which 9 cases with an isolated cutaneous lesion (7 had an infracentimetric lesion). One patient had multibacillary disease although he presented with an isolated skin lesion which developed within the 6 previous months. None presented with disability. Our results suggest that passive detection even reinforced by repeated individual information and education about leprosy is neither appropriate nor effective. The postponed AS seems to favour an increased self-esteem and a better involvement of the index patient in sanitary education together with the screening of his relatives. In the Mayotte background, the postponed AS has not been associated with a significant delay for diagnosis. Although WHO recommandations are to abandon immediate AS of IDC and to promote self-screening for leprosy our study suggests an intermediate position, namely delayed active screening for an enhanced effective detection.
