                                                                            Dengue Fever 

The global incidence of dengue has grown dramatically in recent decades. About half of the world’s population is now at risk. Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. The symptoms of the fever typically begin three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.  Dengue is spread by several species of female mosquitoes of the Aides. Typically, people infected with dengue virus have only minor symptoms such as an uncomplicated fever. Others have more severe illness and in a small proportion it is life-threatening. The growth period ranges from 3 to 14 days, but most often it is 4 to 7 days. Children often experience symptoms similar to those of the common cold, vomiting and diarrhea and have a greater risk of severe complications, though initial symptoms are generally mild but include high fever. The main method to control or prevent the transmission of dengue virus is to combat vector mosquitoes through preventing mosquitoes from accessing egg-laying habitats by environmental management and modification, covering, emptying and cleaning of domestic water storage containers on a weekly basis, applying appropriate insecticides to water storage outdoor containers and so on. Besides, we have to be conscious of it. Similarly, careful clinical detection and management of dengue patients can significantly reduce mortality rates from severe dengue. Actually, there are no antiviral drugs for dengue. However, maintaining proper fluid balance is very important.
