After two years without any cases, São Paulo health authorities reported during the weekend that two patients had died from yellow fever this year after four people were infected. Although both fatalities took place in the State of São Paulo, one of the victims was a resident of Minas Gerais. The State had had no cases of the disease since 2020 when one record was confirmed.
In times when controversies over COVID-19 vaccination mandates keep mounting worldwide, Paraguay's authorities Friday announced a proof of immunization against yellow fever will be required to travelers arriving from or leaving for Bolivia, Brazil, Peru, and Venezuela.
Travelers to Brazil are being warned to vaccinate themselves against yellow fever due to an outbreak of the disease in urban areas, the US Centers for Disease Control (CDC) warned in a press release on Friday.
