Dengue fever continues to be a risk in Brazil

Although cooler temperatures may decrease transmission of the dengue fever virus in some areas, nationwide, there is still a risk of exposure to dengue fever.

  • National data: through mid-June, more than 1,000,000 cases have been reported, along with 736 cases of dengue haemorrhagic fever and 378 deaths
  • 10 states have reported epidemic levels of this infection; these include São Paulo, Acre, Tocantins, Ceará, Rio Grande do Norte, Pernambuco, Minas Gerais, Paraná, Mato Grosso do Sul, and Goias.


Travellers to areas where the dengue fever virus is active can reduce their risk of exposure by taking all necessary precautions to avoid mosquito bites. Many persons with dengue fever do not seek medical care and are not reported to health authorities. There may be many more cases in the community than the reports indicate.
