A recent update published by the World Health Organization (WHO) on October 13, 2021, indicates the Bolivarian Republic of Venezuela's yellow fever concerns have not ended.

Yellow fever infects humans and non-human primates (NHP) and can spread rapidly and cause serious public health impacts in unimmunized populations.

A yellow fever outbreak near the city of Maturin in Monagas state in northeastern Venezuela has resulted in seven yellow fever cases, the WHO reported.

As of October 1, 2021, no yellow fever disease-related deaths have been reported.

The initial case is in a young pregnant woman who was vaccinated, but the other six were unvaccinated.

Vaccination is the most important means of preventing the infection as the disease is preventable with a single dose of yellow fever vaccine, which provides immunity for life.

Safe and effective U.S. FDA Approved yellow fever vaccines have been available for more than 80 years. 

As of October 14, 2021, the YF-VAX vaccine was available in the USA. And the Stamaril vaccine remains available internationally.

Furthermore, since early August 2021, Venezuela has detected ten yellow fever outbreaks involving NHP, such as monkeys, known as epizootic cases.

The confirmed epizootics were identified at 35 km and 150 km from the urban area of Maturín.

The increased number of human cases and epizootics since August 2021 is concerning due to the persistence of high viral circulation, says the WHO.

Previously, the U.S. CDC had issued various high-level Travel Advisory for Venezuela, including for COVID-19.
