isolation hospital
Historical term for a hospital or facility used to isolate patients with infectious diseases; now largely replaced by terms like 感染症指定医療機関.
During the Meiji era, when cholera was prevalent, isolation hospitals were set up in various places.
Compound of 避 (hi, 'avoid') + 病 (byō, 'disease') + 院 (in, 'institution'), literally 'disease-avoidance institution'.
