ABSTRACT
The purpose of this study is to find out, in our area, the role of BCG in prevention of leprosy. A case control study was carried out in Assiut and Abnub districts, the study included 100 leprosy cases under 35 years old [68 males, 32 females] who represented the number of patients drained from several villages. Two healthy matched contacts for every leprosy case were selected as a control. We were looking for BCG scars among leprosy cases and controls at the left deltoid region. Only one leprotic case was vaccinated; 61 contacts of leprosy cases were vaccinated. 99 Leprotic cases were not vaccinated, while 139 contacts of leprosy cases were not vaccinated. The difference between cases and controls regarding BCG vaccination status was highly significant by using x2- test to [p 0.001]
