A survey conducted by the Ministry of Health indicates that at least 357 Brazilian cities are at risk of a renewed dengue, zika and chikungunya outbreak. This indicates that the larvae of the mosquito Aedes aegypti, which transmits such diseases, was found in more than 4% of properties visited in those cities.

Additional 1,139 cities have been put on alert for new outbreaks, having such indicator between 1% and 3.9%.

About 2,450 cities showed a satisfactory situation, with the mosquito found in less than 1% of the properties visited.

The data, which can provide us with a risk overview for next summer, when conditions are conducive for mosquitos to thrive, is from the last LirAa (Rapid Survey of Aedes aegypti Infestation Index).

A total of 3,946 cities were covered by the survey - an increase of 73% compared to previous year. Cities which have not submit their data have until December to send explanations, otherwise funds for inspection may be suspended.

The Northeastern area has the highest number of cities at risk or put on alert: 18.8% in this first group and 41% in the second. The most common type of breeding site for mosquitoes in the area was the storage of water in drums, barrels, and vats.

Aedes aegypti outbreak data also raises the alert for yellow fever, seeing the disease can also be transmitted by this vector in urban areas.
