The International Sanitary Convention for Aerial Navigation (1933) was an
international sanitary convention, drawn up in 1932 and signed at
The Hague on 12 April 1933 (without a conference) and came into force on 1 August 1935 to protect communities against diseases liable to be imported by
aircraft and to protect
air crew against diseases due to flying. It contained a number of regulations consisting of measures to prevent the spread of
plague,
cholera,
yellow fever,
typhus and
smallpox. It was formally ratified by around ten countries. Service aircraft were included in March 1939.[1][2][3][4][5][6] Intelligence on infectious disease at ports was provided to health authorities by the health organisation at the
League of Nations.[5] It was amended in Washington on 15 December 1944, to form the
International Sanitary Convention for Aerial Navigation (1944), which came into force on 15 January 1945.[1][6]
