The purpose of the study was to collect the opinions of doctors who are specialists in infectious disease with regard to the current method used for isolation of patients with group 1 nationally notifiable infectious diseases in Korea. A web-based survey was conducted from June 27 to July 7, 2011. Relevant questions included: 1) adequacy of the current policy of forced hospital isolation; evaluation of current guidelines for release from hospital isolation; and 3) priority for policy switching from forced hospital isolation to home isolation. The rate of response to the survey was 28.4% (40 out of 140). First, the majority of infectious disease specialists in Korea believed that the current method of forced hospital isolation for patients with group 1 infectious diseases should be changed to the home isolation method. Second, if the Korean government changes its policy to home isolation, the top priority of the policy switch would be typhoid fever, followed by paratyphoid fever, shigellosis, cholera, and EHEC (enterohemorigic Escherichia coli). Regarding current guidelines for release from hospital isolation, in cases of shigellosis, EHEC, and hepatitis A, the majority of respondents supported the current guidelines, while they were not able to make collective opinions in cases of cholera and typhoid/paratyphoid fever. We were able to confirm that the majority of specialists want to change the current isolation method. Therefore, the Korean government should consider switching their policy from forced hospital isolation to home isolation.
