How can dengue be prevented?
The only method of preventing dengue is controlling the mosquito infestation. The mosquito causing dengue primarily breeds in man-made containers like metal drums, earthenware jars and other water storage jar. Proper solid waste disposal and improved water storage practices, including covering containers should be encouraged. Insecticides should used periodically. For travelers, going to affected areas, use of mosquito repellents is advised. Vaccination is not yet available. Vaccine development is difficult because any of the four different viruses may cause disease and because protection against only one or two dengue viruses could actually increases the risk of dengue hemorrhagic fever.
