when was the last reported case of leprosy
Leprosy Leprosy is curable with a treatment known as multidrug therapy.[3] Treatment for paucibacillary leprosy is with the medications dapsone and rifampicin for six months.[2] Treatment for multibacillary leprosy consists of rifampicin, dapsone, and clofazimine for 12 months.[2] A number of other antibiotics may also be used.[2] These treatments are provided free of charge by the World Health Organization.[3] Globally in 2012, the number of chronic cases of leprosy was 189,000, down from some 5.2 million in the 1980s.[3][8][9] The number of new cases was 230,000.[3] Most new cases occur in 16 countries, with India accounting for more than half.[3][2] In the past 20 years, 16 million people worldwide have been cured of leprosy.[3] About 200 cases are reported per year in the United States.[10]
Epidemiology John Snow is famous for his investigations into the causes of the 19th century cholera epidemics, and is also known as the father of (modern) epidemiology.[10][11] He began with noticing the significantly higher death rates in two areas supplied by Southwark Company. His identification of the Broad Street pump as the cause of the Soho epidemic is considered the classic example of epidemiology. Snow used chlorine in an attempt to clean the water and removed the handle; this ended the outbreak. This has been perceived as a major event in the history of public health and regarded as the founding event of the science of epidemiology, having helped shape public health policies around the world.[12][13] However, Snowâ€™s research and preventive measures to avoid further outbreaks were not fully accepted or put into practice until after his death.
