Eliminating Malaria | ANNEX | Follow-up of certification Certified countries continue reporting on an annual basis to WHO on the maintenance of their malaria-free status. Outbreaks of malaria in a normally or recently malaria-free country must be reported to WHO immediately, so that WHO can provide assistance if needed, can alert international travellers visiting the affected areas, and can alert neighbouring countries, especially those seeking to eliminate malaria. When there is a falciparum malaria outbreak in a ‘malaria-free’ country, WHO will provide a timely travel alert on the International travel and health website www.who.int/ith, as well as a ‘Note to travelers’ in the first possible Weekly Epidemiological Record. An indication of the re-establishment of transmission would the occurrence of three or more malaria infections that can be linked in space and time to mosquito-borne transmission in the same geographical focus within the country, for two consecutive years for P. falciparum, and for three consecutive years for P. vivax. WHO reports such instances in the annual updates of its publication International travel and health. Countries in which transmission has been re-established are no longer considered malaria-free. The key documents to be prepared by the national government for the certification evaluation team are listed in Annex 11 of the document ‘Malaria elimination, a field manual for low and moderate endemic countries’ (WHO, 2007) and can be accessed http://www.who.int/malaria/docs/elimination/MalariaElimination_BD.pdf .
