A few weeks ago, there was a significant increase in flu cases in Rio de Janeiro. Other states have also begun to warn of similar problems, such as the case of Amazonas, where the outbreak caused the death of more than 60 people during the month of November.
In Espírito Santo the numbers increased significantly, as well as in Minas Gerais and São Paulo, where the state government has already demanded the Ministry of Health about an urgent manifestation regarding the epidemiological scenario of the flu in Brazil.
The influenza A H3N2 virus is to blame and, despite the flu vaccine being composed of a strain of H3N2, it does not cover the Darwin variant that is in circulation in these cities, according to specialists consulted by the Folha de S.Paulo newspaper. Originally, Darwin was discovered in Australia.

It is the strain that Fiocruz identified in the outbreak in Rio,” Nancy Bellei, infectologist, professor at Unifesp and coordinator of testing at Hospital São Paulo, told Folha.
