I'm on the U.S. Embassy's mailing list and I just received the following e-mail about the Dengue Fever Outbreak, a vector born disease. It's good I'm no where near mosquitos because I'd be the first one to be covered in bites. All the exchange student trips to the north have been postponed.
"This Warden Message, a follow-up to our message of March 27, 2009, is to alert U.S. citizens in and traveling to Argentina that the Argentine Ministry of Health reported 10,594 confirmed cases of dengue fever in Argentina as of April 12, 2009. Up until recently, cases had been restricted to the northern Argentine provinces of Chaco, Salta, Catamarca, Tucuman, Corrientes and Jujuy, however 107 cases have now been confirmed in the capital and in Buenos Aires Province. The Health Ministry reported that all suspected and confirmed cases in Buenos Aires had been imported from the most affected provinces, but media reports said that at least five infected people had not traveled outside of the capital region. Dengue fever is a mosquito-transmitted illness, for which there is no vaccine, and no specific treatment. Dengue hemorrhagic fever is a rare, more severe and sometimes fatal form of the disease. For the latest information, you may visit the ministry's website at http://www.msal.gov.ar/htm/site/default.asp or call 0800-222-1002.
The Ministry of Health recommends eliminating sources of standing water, which form breeding grounds for mosquitoes. To further reduce the risk of contracting dengue, Argentine officials and the Centers for Disease Control and Prevention (CDC) recommend wearing clothing that exposes as little skin as possible and applying a repellent containing the insecticide DEET (concentration 30 to 35 percent) or Picaridin (concentration 20 percent or greater for tropical travelers). Because of the increased risk of Dengue fever and the ongoing risk, practicing preventative measures is recommended by the CDC.
