The Ministry of Health made this warning because newly affected areas and large populations, such as the metropolitan areas of Rio de Janeiro, Minas Gerais and São Paulo, still had high numbers of people who were not vaccinated against fever. yellow and therefore increases the risk of infection.

In 2017, when there was an outbreak of yellow fever, vaccination was expanded to 4,469 municipalities.

Vaccination coverage must be at least 95% of the population.

In the National Vaccination Calendar, yellow fever vaccines are offered and distributed to the state every month, and this year 30 million doses of the vaccine against the disease have been sent throughout the country. However, vaccination is little sought by residents. People must take doses at least 10 days before going to the risk area.

What is yellow fever?

Yellow fever is an infectious disease caused by a virus and is transmitted by mosquitoes. Infection can be categorized in two ways: urban yellow fever, when transmitted by Aedes aegypti, or wild yellow fever, when transmitted by Haemagogus and Sabethe.

This disease is considered acute and hemorrhagic and is named because it causes yellowing of the body (jaundice) and bleeding to various degrees. This virus is tropical and is most common in South America and Africa. Even though it is considered a dangerous virus, most people have no symptoms and evolve to be cured.
