Notifications from the Ministry of Health for vaccination with yellow fever


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

The health ministry warning comes because newly affected areas and large population groups such as the metropolitan areas of Rio de Janeiro, Minas Gerais and Sao Paulo still have a large number of unvaccinated people, a risk of getting sick.

The disease has a high mortality rate of about 40%, which makes the condition more severe.

Since the outbreak that broke out in December 2017, vaccination for yellow fever has spread to 4,469 municipalities. This is due to the integration of 940 cities located mainly in the capitals and metropolitan areas of the southeastern and southern regions of Brazil, where there were evidence of virus circulation. Coverage of vaccination should be at least 95% of the population.

"We need to ensure that, especially in the municipalities of Rio de Janeiro and Sao Paulo, where many of these have happened in the last two years, preventive vaccination takes place in the summer when there is more virus," explains Carla Domingues, coordinator of the National Immunization Program.

According to the new epidemiological report, 271 yellow fever reports were reported from 1 July to 8 November this year, of which 150 were rejected, 120 were still under investigation and 1 confirmed. Also, at this time, 1,079 epizootics were reported in non-human primates. The new monitoring period is from July 1, 2018 to June 30, 2019.

Data show that virus circulation remains in the low-onset period (June to September), when low temperatures and rainfall generally result in conditions less conducive to transmission.
