Article 83

Every aircraft leaving an airport situated in an area where transmission of malaria or other mosquito-borne disease is occurring, or where insecticide-resistant mosquito vectors of disease are present, or where a vector species is present that has been eradicated in the area where the airport of destination of the aircraft is situated, shall be disinsected in accordance with Article 26 using the methods recommended by the Organization. States concerned shall accept disinsecting of aircraft by the approved vapour disinsecting system carried out in flight. Every ship leaving a port in the situation referred to above shall be kept free from the immature and adult stages of the mosquito concerned.

On arrival at an airport in an area where malaria or other mosquito-borne disease could develop from imported vectors, or where a vector species has been eradicated that is present in the area in which the airport of origin is located, the aircraft mentioned in paragraph 1 of this Article may be disinsected in accordance with Article 26 if the health authority is not provided with satisfactory evidence that disinsecting has been carried out in accordance with paragraph 1 of this Article. Every ship arriving in a port in the situation referred to above should be treated and freed, under the control of the health authority, from the immature and adult stages of the mosquito concerned.

As far as practicable, and where appropriate, a train, road vehicle or other means of transport, container or boat used for international coastal traffic, or for international traffic on inland waterways shall be kept free of insect vectors of human disease.
