So far this year there have been 200 confirmed cases of an extremely aggressive strain of dengue virus in Mexico's Pacific coast state of Sinaloa. The new strain has prompted that state's Secretary of Health to issue a warning to residents to take precautions to reduce its potential spread, by eliminating standing water where mosquitoes breed. Sinaloa encompasses the resort town of Mazatlan.

So far this year there have been 200 confirmed cases of an extremely aggressive strain of dengue virus in Mexico's Pacific coast state of Sinaloa.

Sinaloa encompasses the resort town of Mazatlan.
Secretary Héctor Ponce Ramos, indicated that this year's strain of dengue fever is more lethal than in previous years and may be based on DENV-3 AND DENV-4 strains of the disease, which in theory would yield very deadly results and has only rarely been seen before.
From the CDC:
"Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. Infection with one of these serotypes provides immunity to only that serotype for life, so persons living in a dengue-endemic area can have more than one dengue infection during their lifetime. DF and DHF are primarily diseases of tropical and sub tropical areas, and the four different dengue serotypes are maintained in a cycle that involves humans and the Aedes mosquito.
