Dengue fever is caused by mosquito bites and these mosquitoes are the carrier of dengue. Dengue is a killer, especially when not immediately diagnosed. Many children died because of this type of fever. When diagnosed, immediately bring the sick person to the nearest hospital and seek medical attention. Regularly, dextrose will be immediately given to patients. If worse comes to worse, a blood transfusion must be administered immediately to save the life of the patient.
