Dengue Fever
Dengue fever is caused by one of the four dengue viruses and spread by Aedes aegypti type of mosquitoes. The viruses causing dengue are the same as those that cause yellow fever and West Nile infection. People who contract dengue fever usually start showing symptoms in 4 to 7 days after the initial infection.
If proper care and the right course of treatment is given to the patient, recovery is quick. Patients suffering from severe dengue need supportive care in a hospital, continuous monitoring of blood pressure, and transfusion to replace blood loss.
