The mosquito can spread yellow fever, an acute viral hemorrhagic fever. But an increasing number of people also have been infected, making it Brazil's worst yellow fever outbreak among humans in decades. Although there is a highly effective vaccine for yellow fever, it is not routinely given in Brazil’s major urban centers, they said. The entire state of Espirito Santo is considered at risk for yellow fever transmission, the WHO said this week. “The yellow fever outbreak in Brazil is yet another reminder of the dangers posed by mosquito-borne diseases around the world,” said Erin Staples, a medical epidemiologist at the CDC.
