Leprosy was said to be first recognized in the ancient civilizations of China, Egypt and India, according to the World Health Organization (WHO). Leprosy, also known as Hansen's disease, was officially eliminated at the national level in China by 1982, meaning prevalence is lower than 1 in 100,000. There are 3,510 active cases today. Though leprosy has been brought under control in general, the situation in some areas is worsening, according to China’s Ministry of Health. In the past, leprosy sufferers were ostracized by their communities as the disease was incurable, disfiguring and wrongly thought to be highly infectious.

Most of these sufferers have been cured but approximately 6,000 active cases remain today and about 2,000 new cases are detected and registered every year. Many more cases are not registered, partly through ignorance, but also because of the stigma associated with the disease.
