Mexico City (Agenzia Fides) - According to health authorities in Mexico, the country closed the year with an increase of 50% more cases of dengue fever than those recorded in 2008. Among the causes of the increase include the mutation of the insect vector, the Aedes aegypti, which now reproduces itself almost year round, even in winter.
According to the Health Ministry, the mosquito has developed resistance to insecticides and has managed to adapt to areas of higher altitude, thus extending the areas of infection.
The latest report from the National Center for epidemiological surveillance indicates that cases of classical dengue fever reported in 2009 were 40,865, up from 27,479 in 2008. (AP) (Agenzia Fides 4/1/2010)
