Leprosy is a chronic infection caused by the acid-fast, rod-shaped bacillus Mycobacterium leprae. Leprosy can be considered connected diseases that primarily affect the superficial tissues, especially the skin and peripheral nerves. The social and psychological effects of leprosy, as well as its highly visible debilities and sequelae, have resulted in a historical stigma associated with leprosy. Vietnam has seen a highly significant decrease in the prevalence rate (PR) of leprosy since 1983. From 1983 onwards, with the introduction of multidrug therapy (MDT), the prevalence of the disease has dropped to less than one case per 10,000 individuals from 1995. After over two decades, a total of 109 cases were registered with a prevalence rate of 0.01 per 10,000 population in 2017. It is clear that over the past 35 years, the profile of leprosy in Vietnam has been changed significantly followed by the treatment with MDT. Leprosy has become a rare disease in Vietnam. This chapter presents the trend in the epidemiology of leprosy in Vietnam from 1983 to 2018 and also mentions the effectiveness of multidrug therapy (MDT) in the management of this disease. Based on individual records and annual reports, the prevalence of registered cases, the number of new cases detected yearly, their sex, age, classification (MB, multibacillary; PB, paucibacillary) and disability status are carefully presented.
