Through the seventh week of 2016, Mexico has reported 10,702 total dengue fever cases, up from 6,892 cases during the same period last year. 1,496 cases have been laboratory confirmed.

Nearly 500 cases of severe dengue have been reported and to date, no deaths have been noted.

The states seeing the most dengue to date include Jalisco (1601), Nuevo Leon (1290) and Guerrero (1060).

All four dengue serotypes have been reported with DENV-1 being the most common. Oaxaca is the only state reporting all four.

Dengue is an infectious disease caused by the dengue virus (DENV). There are 4 serotypes called DENV-1, DENV-2, DENV-3 and DENV-4. Infection with one serotype produces lifelong immunity against that serotype reinfection. Successive infection with two different serotypes is a risk factor for developing the severe forms of the disease.

All serotypes have been isolated in the Americas. In several countries they circulate simultaneously, creating a serious risk for an epidemic.

The Aedes aegypti and Aedes albopictus mosquitoes are transmitters of dengue.
