The number of reported cases of dengue, a mosquito-borne illness, has more than doubled in the past year in Great Britain, with the majority linked to travel to India, the country's Health Protection Agency (HPA) said on Wednesday, Reuters reports. The agency reported 406 cases of the disease among Britons who traveled abroad during 2010, up from 166 reported cases in 2009, with 21 percent of cases occurring among people who had traveled to India and 15 percent among people who had gone to Thailand, according to the news service. The WHO estimates that two-fifths of the world's population is at risk of contracting dengue. In addition, the HPA reported 79 cases of chikungunya, another mosquito-borne disease, or a 34 percent increase over 2010 figures, Reuters adds (Kelland, 5/11).
