Observations on reactions of leprosy in the field.

ABSTRACT

In order to assess the incidence of reaction in leprosy, it would be necessary to examine the data from a field control unit. In this study, it was found, at a fully monitored control unit, that Type I reaction occurred in 3.9% of borderline cases and Type II in 23.7% of LL and BL cases. Even so, the load of reaction is not high since reaction of Type I and Type II together are seen only in 3.7% of all types of cases. A majority of them are of mild or moderate degree and could be treated as out-patients. Of the borderline cases, the BB type showed maximum rate of reaction. The BL type can present with both Type I and Type II reactions with a total incidence of 12.8%. While the BT type constituted 74% of total cases, reaction of Type I occurred in 3.1% of cases. Reaction also occurred in 0.8% of RFT cases.
