Brazil has reported 
83 cases and 28 deaths from yellow fever since 24 January 2018. These cases occurred in São Paolo (47), Minas Gerais (27) and Rio de Janeiro (9) states. The total from July 20187 to 30 January 2018 now stands at 1 080 cases. Of these, 213 cases are laboratory confirmed, with 81 deaths.
Media quoting Brazilian health authorities advise visitors to the Rio de Janeiro Carnival avoid sightseeing at waterfalls and forests, as these areas present a risk of yellow fever transmission. Authorities say the risk remains low in Rio de Janeiro city.
Recent expansion of yellow fever into the municipality of Sao Paulo and the municipalities of Greater São Paulo (Cajamar, Caieiras, Mairipora, Franco da Rocha, Guarulhos, and Itapecerica da Serra), indicate high risk for non-immunized people. The World Health Organisation (WHO) considers all of São Paulo State as being at risk of yellow fever transmission.
