Ministry of Health alerts for yellow fever vaccination


The population living in areas recommended for the yellow fever vaccine should seek vaccination before the beginning of summer, the period of greatest risk of transmission of the disease.

The Ministry of Health's warning comes because recently affected areas and large population groups, such as the metropolitan areas of Rio de Janeiro, Minas Gerais and São Paulo, still have a large number of unvaccinated people, that is, that are under risk of becoming ill.

The disease has a high lethality, around 40%, which makes the situation more serious.

Since the outbreak recorded in December 2017, vaccination for yellow fever has been expanded to 4,469 municipalities. This was due to the inclusion of 940 cities located mainly in the capitals and metropolitan areas of the Southeastern and Southern regions of Brazil, where there was evidence of viral circulation. Vaccination coverage should be at least 95% of the population.

"We need to ensure that, especially in the municipalities of Rio de Janeiro and São Paulo, where many cases have occurred in the last two years, there is a preventive vaccination in anticipation of the summer when there is a greater circulation of the virus," explains Carla Domingues, coordinator of the National Immunization Program.

According to the new epidemiological bulletin, from July 1 to November 8 of this year, 271 suspected cases of yellow fever were reported, of which 150 were discarded, 120 remain under investigation and 1 was confirmed. Also in this period, 1,079 epizootics were reported in non-human primates. The new monitoring period is from July 1, 2018 to June 30, 2019.

The data show the maintenance of viral circulation in the period of low occurrence (June to September), when low temperatures and rainfall generally imply conditions less conducive to transmission.
