The Brazil Health Ministry is now reporting suspected yellow fever cases in the states of Goiás and Mato Grosso do Sul, this is in addition to the four states previously reported–Minas Gerais, Espírito Santo, Bahia, São Paulo (the suspect cases in Federal District have been ruled out).

Earlier this month, the World Health Organization (WHO) expressed concern that yellow fever could quickly spread from the outbreak’s ground zero to other states in the north and west because of the region’s low rates of vaccinations and mosquito-friendly environments.
