Rapid survey on case detection of leprosy in a low endemic situation, Zhucheng County, Shandong Province, The People's Republic of China.

摘要

The prevalence of leprosy fell below 1 per 100,000 in Shandong province in 1994. Since then, a few incident leprosy cases have been reported each year over the past 10 years. In order to explore whether or not the reduction in case detection in the province was due to the stopping of active case-finding activities, a rapid village survey was conducted in a formerly endemic county, using skin disease service. Ninety-one villages in 23 townships, covering a total population of 104,885, were surveyed. No leprosy case was detected. The results of the survey, along with other evidences, such as higher MB/PB ratio among newly detected cases and late onset of the disease, suggest that leprosy is dying out as a disease in the county as well as in Shandong. The efforts of the leprosy control programme should shift to other services such as prevention of disability and care for the disabled.
