International travellers could be at risk of malaria infection in 91 countries around the world, mainly in Africa, Asia and the Americas. Each year, WHO (World Health Organisation) releases International Travel and Health, a comprehensive and up-to-date guide regarding the prevention and treatment of all diseases potentially affecting travellers. The publication is aimed at health practitioners and national disease control centres, and includes information about the geographical distribution of malaria, epidemiological details for all malaria-endemic countries, and all recommended preventive measures. Always check with your health practitioner before travelling to any of these countries.
