Dengue is caused by the four serotypes of dengue virus (1-4). An infection with one of the serotypes does not protect an individual against the other serotypes and multiple infections of dengue virus can put individuals at greater risk for dengue hemorrhagic fever.
The symptoms of dengue fever are:
- high fever
- severe headache
- joint pain
- rash
- mild bleeding
Dengue hemorrhagic fever includes a fever for 2-7 days followed by the capillaries in the body being permeable and causing leakage. This can lead to shock and possibly death.
Dengue is endemic in 100 countries in Asia, the Pacific, the Americas, Africa, and the Caribbean including parts of Mexico. Arizona has only had travel-associated dengue cases.
Arizona 5 year median: 14 cases
Transmission
Transmission occurs when an infected Aedes aegypti or Aedes albopictus mosquito bites an individual.
Transmission can also occur from blood transfusions or organ donation from an infected individual.
