Dengue fever is spread by Aedes Aegypti mosquitoes, and thanks to the extra rain South America is getting, those mosquitoes are breeding like flies.  Even Hawaii, in the Pacific Ocean, is reporting cases.

Brazil is the hardest hit, so far, already more than 30,000 cases, just in the state of Rio alone, and at least 23 dead. The capitol city Rio de Janeiro is reporting that so far this year, cases have skyrocketed 2059%, compared to the same time last year.

Argentina is already warning of the spread of Dengue to other South American countries as the wet weather continues.

In Paraguay, so many people have crowded into hospitals with Dengue that officials canceled elective surgeries to free up beds. So far this year 18 people have died of Dengue in Paraguay. Compare that to all of last year, when they had 15 deaths.

The U.S. Center for Disease Control (CDC) has confirmed at least four cases in Pearl City, Oahu, Hawaii, with 12 more suspected cases.  In Hawaii Dengue is spread by the Asian Tiger mosquito (Aedus Albopitus).

CDC officials say Dengue originates in humans, but is spread by mosquitoes.  Tracking Dengue fever is more about tracking where infected humans travel. Most people show no symptoms. The CDC website has more information.

Dengue cases are hitting all over the world, in mainly humid climates, or areas that are getting more rain than usual.
