The Ministry of Health gives this warning because areas where a new disease has been affected and with a large population, such as the metropolitan areas of Rio de Janeiro, Minas Gerais and Sao Paolo, still have a large number of people who have not been vaccinated against fever yellow and therefore have an increased risk from infection.

In 2017, when there was a yellow fever outbreak, the vaccination was extended to 4,469 municipalities. This happened due to the inclusion of 940 cities near the capitals and metropolitan areas of the southeast and southern region of the country, where there was evidence of viral circulation. Vaccination coverage should be at least 95% of the population.

In the National Vaccine Calendar, a yellow fever vaccine is offered and distributed to countries each month, and this year 30 million doses of the vaccine against the disease have been sent across the country. However, the population does not require vaccination. People should take a dose at least 10 days before going to risky areas.

What is yellow fever?

Yellow fever is an infectious disease caused by the virus and transmitted by mosquitoes. The infection can be categorized in two ways: urban yellow fever when transmitted Aedes aegipti, or wild yellow fever, when transmitted Haemagogus i Sabet.

The disease is considered acute and haemorrhagic and is called because it causes yellowing of the body (jaundice) and bleeding in different degrees. The virus is tropical and most common in South America and Africa. Despite being considered a dangerous virus, most people have no symptoms and are developing to cure.

Yellow fever belongs to the classification of arboviruses, with several differences between dengue and Zika virus, although they belong to the Flavivirus family. Learn more about yellow fever.
