To investigate an outbreak of scabies that occurred in geriatricfacilities located in Kyounggi-province, Korea, between September 2004 and September 2005.
We carried out an epidemiologic investigation on the scabies outbreak. All workers except two were interviewed and the charts of the patients were reviewed.
Among workers, the attack rate was 58.6% (17/29). The rate was 86.0%(37/43) in patients. Secondary cases also occurred among the family members of workers, with a secondary attack rate of 15.8%. The 95% confidence interval was 6%~31.3%. The transmission of scabies began from one index case who had scabies and moved from another facility. She was hospitalized on the 4th floor of this facilitywhere dependent patients resided. After the activities (picnic and yard sale) in May 2005, and the ward rotation of care givers between the 3rd and 4th floor in July 2005, the incidence of scabies increased. The last cases occurred in Sep. 2005.
This outbreak investigation has importance because it is the first report of ascabies outbreak in geriatric long-term care facilities in Korea. Recently, the reports on a scabies epidemic are increasing with the augmentation of geriatric long-term care facilities. It is important to educate and inform workers and staff in long-term care facilities about scabies and other contagious skin diseases. More facilities for senility and dementia will be opened and we need to lookinto contagious diseases in long-term care facilities.
