Yellow Fever Outbreak In Brazil Could Become An Epidemic, Of
Public health officials in Brazil suspect that a small yellow fever outbreak in Minas Gerais, a populous landlocked state adjacent to São Paulo state, has infected 110 people and killed 30, according to a Friday report.

There is a vaccine for yellow fever, but because the outbreak is taking hold in areas with low vaccination rates, officials are concerned that the disease could continue to spread beyond the state’s borders and cause a larger epidemic, according to the World Health Organization. Yellow fever is spread by the same mosquito that spreads Zika virus, dengue fever and chikungunya.
