Brazilian states and municipalities report large numbers of dengue fever cases (update)

Many states (Ceará, Pará, Paraná, Espírito Santo, Bahia, Mato Grosso, Mato Grosso do Sul, Minas Gerais, and São Paulo) and some municipalities in those states continue to report very large numbers of dengue fever cases, including a significant number of deaths. From a low of approximately 14,000 cases (Ceará) to a high of over 230,000 cases (Minas Gerais), dengue fever has been a major public health risk in both rural and urban areas in Brazil this year.

There may be many unreported cases of dengue since counting and reporting cases may be hampered by lack of local access to health care, and many persons with mild illness may not seek health care. Travellers to areas where the dengue fever virus is active can reduce their risk of exposure to dengue fever virus by taking all necessary precautions to avoid mosquito bites.
