The number of confirmed cases of dengue in Yucatan grew to 66, according to the latest report of the National Epidemiological Surveillance System (Sinave). That is a significant increase in the virus spread by the Aedes Aegypti mosquito.

This time last year, Yucatan saw only three active cases of dengue.

Of the cases confirmed so far, just one is severe, and no deaths have been reported.

The municipalities of Muxupip, Sanahcat, Chankom and Dzitás reported the highest number of cases last week.

This is why health authorities have had to reinforce fumigation campaigns throughout the state. Normally, they wait until May or June — the beginning of rainy season — to ramp up spraying and other anti-mosquito work.

Officials also patrol neighborhoods to ensure properties are clean, tidy and free of useless objects that accumulate water, which are potential breeding grounds for mosquitoes.
