International Civil Aviation Organization (ICAO) and IATA

Te międzynarodowe organizacje Aviation (ICAO) ustalają standardy for civil aviation, and during outbreaks it collaborates with the WHO to publish joint guidance for cabin crew, ground handlers, and border authorities. The International Air Transport Association (IATA) completes these effects by y providing operational toolkits, including the Medical Manual for Airline Personal, which detals howw to require symptoms, isolate ill traveleres, and clean contaminated areas. IATA also advocates for harmonized measures across grands, arguing that a patchwork of national rules creates confusion and erods passenger confidence.
