Epidemiological studies of sarcoptic mange in Tanzanian pig herds.

An epidemiological survey of sarcoptic mange in 32 herds with a total herd size of 2,021 pigs was conducted in three representative climatic zones in Tanzania. The disease was present in all zones in varying prevalences. The overall prevalences were 52% and 21% when determined on the basis of clinical examination and mite isolation respectively and 91% of the herds were shown to be harbouring the disease.
