Sorocaba, São Paulo State

Since the beginning of 2011, 1,714 dengue cases have been confirmed in the city. However, only 8 new cases have occurred recently. 

Although cooler temperatures are contributing to a decrease in the mosquito population and thus a decrease in cases, travellers should be aware that there may be a residual risk of exposure to dengue fever virus, especially in the more tropical areas of northern Brazil. Travellers should take all necessary precautions to avoid mosquito bites.
