Since my last posting about Dengue fever, in April 2011, the disease is infecting even more people in even more countries.

Asia is seeing the most increase in cases this year.

As of July 11, the Philippines has tens of thousands of cases, and almost 200 deaths.  Officials are warning that when the rainy season hits, they expect Dengue cases to jump.

In India, just one hospital treated 160 children with Dengue, 10 of which died.  Indian officials are also warning of a sharp increase in cases when the rainy season starts.

In Australia, health officials are reporting that many Australians, returning from vacations, are coming home infected with Dengue.  So far 354 cases have been confirmed.  Last year Australia had only 156 confirmed Dengue cases.

In Saudi Arabia, just in the capital city of Jeddah, an average of 130 new cases are being reported every week.

In Mexico an experimental Dengue vaccine is being tried on 1,000 children in the towns of Valladolid and Tizimín.  The vaccine is in the third stage of study, before it can be approved for widespread use.

In Peru, the mayor of one city has ordered fumigation of the entire city, after 10 people became sick with the hemorrhagic fever.  Two of the infected have died.  As many as 150 Peruvians are sick with Dengue.

Brazil has been enjoying some success in fighting Dengue.  So far this year 340 cases have been confirmed, compared to last year’s 2589 cases (then again this year isn’t over).

Dengue is spread by mosquitoes. Travelers are being warned of vacation spots that have high risk of Dengue hemorrhagic fever:  Asia, Africa, Middle East and South America.
