Abstract
Hand hygiene is a basic but effective strategy against infectious disease. This study investigated an ecological association between hand hygiene and tuberculosis (TB) risk in Korea. Hand hygiene data were obtained from the 2015 Community Health Survey. Information on TB incidence and mortality in 2015 were obtained from the National Infectious Diseases Surveillance System and death monitoring database, respectively. In multiple linear regression analysis, frequent hand washing rates after using the restroom (B = −0.78, P = .037), after returning from the outdoors (B = −0.28, P = .049), and with soap or hand sanitizer (B = −0.54, P = .018) were negatively associated with TB incidence. TB mortality were associated with frequent hand washing rates after returning from the outdoors (B = −0.05, P = .035), and with soap or hand sanitizer (B = −0.10, P = .010), respectively. Hand washing was associated with lower TB incidence and mortality at the community level. These results could contribute to develop community-based health promotion strategies.
