Plague Hospital (Lazaretto)

Timeline

1. 1423–1450Venice · VeniceThe Republic of Venice established Lazzaretto Vecchio and Lazzaretto Nuovo on lagoon islands, concentrating suspected infections and goods for isolated observation and creating a specialized plague institution distinct from ordinary charitable hospitals.
2. 1500–1700Mediterranean coast · MediterraneanThe lazaretto model spread along Mediterranean–Atlantic trade routes: ports set up quarantine stations, patients and goods were held on separate islands or in separate warehouses, and these linked with city plague hospitals, becoming core facilities of early cross-border health control.
3. 1600–1800Major European ports · EuropeStates promulgated quarantine regulations; lazarettos combined customs health inspection, patient isolation, and terminal care; some institutions introduced more systematic ward divisions and record-keeping, providing an institutional prototype for modern epidemic surveillance.
4. 1800–1900Europe · EuropeAdvances in bacteriology and international health conventions promoted unified quarantine standards; most specialized lazarettos were merged into general infectious disease hospitals or abolished, but their 'port isolation—centralized treatment' logic continued into modern customs and CDC-style disease control.
