In 2010, 406 individual cases of dengue fever were reported in England, Wales and Northern Ireland compared to 166 in 2009. Dengue fever does not occur in the United Kingdom. All cases reported have been acquired as a result of travelling to endemic areas, the majority to South and South East Asia, South and Central America, Africa and the Caribbean. [See table: note that the totals in the table are higher than the total cases as some cases had travelled to more than one country.] See the dengue annual reports for further information.
