Maps of the country of origin of P. falciparum cases amongst UK residents travelling to malaria endemic areas in 2007, number of UK residents travelling to each malaria-endemic country and the estimated entomological infection rate for each malaria-endemic country. (A) The number of cases imported to the UK in 2007 by country of reported travel exposure. (B) The number of UK residents travelling to malaria-endemic areas in 2007 . White areas are those that are considered non-endemic. (C) Estimated entomological infection rate (EIR, in units of infectious bites per person per year) for each malaria-endemic country.
