The mosquitoes that carry the dengue viruses are found abundantly in tropical cities, breed in and around homes, and preferentially bite human beings. Dengue fever is characterized by sudden onset of high fever, severe headahe, joint and muscle pain. Many patients have nausea, vomiting and a rash that appears 3-5 days after onset of fever and may spread from torso to arms, legs and face. Where Is It? Dengue fever is a rapidly expanding disease in most tropical areas of the world. The incidence of severe disease has increased dramatically in Southeast Asia in the past 20 years. Prevention Tips There is no specific treatment for dengue infection. The mosquitoes that carry the dengue viruses are 'day biting'. While these mosquitoes may bite at any time during the day, they tend to feed indoors, in shady areas, or when it is overcast. Other peak feeding times are in the morning for several hours after daybreak and in the late afternoon for several hours before dark. Travellers can reduce their risk of acquiring dengue by; remaining in well-screened or air conditioned areas when possible wearing clothing that adequately covers the arms and legs applying DEET-containing insect repellent to both skin and clothing. Available Immunizations At this time, there are no vaccines available for prevention of dengue fever. Always practice personal precautions against mosquito bites.
