What Is Dengue Fever?
2. Causes
Dengue fever is caused by a virus in the genus flavivirus, and there are 5 known serotypes of the virus. The virus is spread when a mosquito feeds from an infected person, potentially causing them to become infected also. When the same mosquito then goes on to bite another person, the disease can be transmitted to that person.
Dengue fever is caused by any one of four types of dengue viruses spread by mosquitoes that thrive in and near human lodgings. When a mosquito bites a person infected with a dengue virus, the virus infects the mosquito. When the infected mosquito then bites another person, the virus enters that person’s bloodstream.
