The preventive and control measures include: (a) early diagnosis and treatment of leprosy and surveillance of contacts, (b) health education, (c) vaccines, and (d) chemoprophylaxis.
No skin or serologic tests are available to identify a carrier of leprosy. It is essential to monitor household contacts of patients with lepromatous disease annually for 5 years after diagnosis.
It is important in prevention and control of leprosy in population.
Many studies using one or more antileprosy drugs (dapsone, acedapsone, and rifampicin) as chemoprophylaxis against leprosy have failed to show any significant protection against leprosy. Therefore, at present, detection and MDT for all patients with leprosy is the useful method for early prevention of leprosy.
