چکیده
© 2005 The Medicine Publishing Company Ltd 18 MEDICINE 33:7 Dengue is a viral infection transmitted by mosquitoes. It causes more illness and death than any other arboviral infection, and its control is a priority for the WHO. Dengue viruses are flaviviruses closely related to yellow fever virus and Japanese encephalitis virus. There are four serotypes (1, 2, 3 and 4). Infection with one serotype does not induce solid immunity to the others, and individuals may be infected with dengue more than once. Dengue is transmitted from infected to susceptible humans by day-biting Aedes (Stegomyia) aegypti mosquitoes. This mosquito lives in urban environments, breeding in small collections of clean water in and around human habitats. Dengue is not transmitted directly between humans; therefore, special infection control measures are not required for suspected cases in hospital.
