(Canada--Canadian Family Physician, May 2000, p. 1126.) Dengue fever is increasing in incidence and is now the most common arbovirus infection among persons who travel to tropical Africa, South and Central America, the Caribbean, Asia and Oceania. Dengue fever is transmitted by mosquitoes of the genus Aedes, which bite during the day and are abundant near stagnant water in urban areas. To avoid dengue fever, travelers should wear clothing that covers the arms and legs and use insect repellant containing diethyltoluamide (DEET). Currently, there is no vaccine to prevent dengue fever. Patients usually present with arthralgias, myalgias, headache and a rash resembling measles. A rarer, more severe form of dengue fever with hemorrhagic fever occurs mainly in persons younger than 15 years.
