" Troubling trends in dengue fever outbreaks are worrying health authorities and elected officials in Mexico. In 2010; deaths from the illness are running ahead of last year's fatalities. Dengue-transmitting mosquitoes are turning up in unexpected areas, and the pests are showing resistance to previously-applied insecticides. The federal Secretariat of Health has called on officials to "undertake the greatest efforts at safeguarding the health of the citizenry."
Until recently, dengue had been a problem in low-lying tropical areas along Mexico's coasts. Recently, however, the National Center for Epidemiological Monitoring and Disease Control (Cenavece) has detected Aedes aegypti, the mosquito which transmits the virus causing dengue, in unusual places including the Mexico City metropolitan area, Cuernavaca, Aguascalientes and Queretaro.
According to Health Secretary Jose Angel Cordova, transmitting mosquitoes are now found in zones higher than 5,000 feet — far above elevations where the bugs were previously found.
In Sonora, health authorities reported 65 cases of dengue through the third week of July, mainly in the state capital of Hermosillo and municipalities in the southern part of the state. In Guerrero, meanwhile, state health officials reported a 40 percent increase in dengue cases over last year's numbers. Most of the sicknesses were in the resort city of Acapulco. By the third week of July, the Guerrero State Health Department registered 2,491 cases, including six deaths. Nationwide, 8,850 dengue cases — including 16 fatalities — were tallied in the same time period."
