Contamination rates were 18.4, 10.5 and 10.5% in the youths, drug abusers and kitchen units, respectively. Adults, foreigners and quarantine units were contaminated 7.9, 5.3 and 5.3%, respectively. In cheque and military units, no contamination was observed because of the higher hygienic status. Morbidity rate in the individual and technical units was 2.5%. The highest and the least morbidity rates were observed among 20-29 year age group (55.2%) and over 50 year age group (2.6%). The average and the mean ages of the 38 patients that contaminated to Sarcoptes scabiei was 29 +/- 8 and 28 years, respectively.
