This has prompted the World Health Organization Secretariat to determine that the State of Rio de Janeiro, with the exception of the urban areas of Rio de Janeiro City and Niterói,  should also be considered at risk for yellow fever transmission.

Last Thursday, Brazilian authorities identified 47 municipalities in Rio de Janeiro that were a priority for a vaccination campaign, including the municipality of Casimiro de Abreu, where the two confirmed cases are reported.

Since the beginning of the Brazil yellow fever outbreak in December 2016, 1,357 cases (933 suspected and 424 confirmed), including 249 deaths (112 suspected and 137 confirmed) have been reported. The case-fatality rate is 18.3% among all cases and 32.3% among confirmed cases.

In Ecuador, the IHR National Focal Point of Ecuador reported a confirmed case of yellow fever to PAHO/WHO; the case is a 31-year-old male patient in the province of Sucumbios, which borders Colombia.

Prior to this case, the last confirmed yellow fever case in Ecuador was reported in 2012 in the province of Napo.

In Suriname, a laboratory confirmed case of yellow fever was reported in a traveler from the Netherlands who had not been vaccinated for yellow fever and had remained in Suriname from mid-February to early-March 2017.
