The Ministry of Health recommends vaccination against yellow fever before summer


Early summer is considered to be the greatest risk of transmission of yellow fever. Therefore, the population living in risk areas should seek vaccination as soon as possible.

The health secretariat makes this warning because areas recently affected by the disease and with a large population, such as the metropolitan areas of Rio de Janeiro, Minas Gerais and São Paulo, still have a large number of people not vaccinated against fever yellow and therefore have an increased risk of infection.

In 2017, when there was an outbreak of yellow fever, the vaccination was extended to 4 479 municipalities. This was due to the introduction of 940 cities near the capitals and metropolitan areas in Southeast Asia and the southern regions where there was evidence of viral circulation. The vaccination coverage should be at least 95% of the population.

In the national vaccination calendar, yellow fever vaccine is offered and distributed to states every month, and this year, 30 million doses of vaccine against the disease have been sent all over the country. However, the vaccination is little sought after by the population. People should take the dose at least 10 days before going to risk areas.

What is yellow fever?

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

The disease is considered acute and hemorrhagic and is called because it causes yellowing of the body (jaundice) and bleeding to varying degrees. The virus is tropical and most common in South America and Africa. Although they are considered to be a dangerous virus, most have no symptoms and develop to cure.

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