    Influenza outbreak: H3N2 cases increased 1,380% in Salvador in 14 days
    Yvonne Lipsey December 15, 2021 6 min read

    Allied to COVID-19, influenza syndromes worry Salvador’s Municipal Health Ministry. And one more than the others: influenza caused by H3N2, a type of influenza A virus, which has increased 1380% in cases in the capital, in the last 14 days. On December 1, five patients were registered in the city. This Tuesday (14), there were already 74, according to SMS. In just the last 24 hours, there have been 21 diagnostic confirmations.

    For this reason, Mayor Bruno Reyes (Democratic), I had to reopen Bao Miodo flu To reduce pressure on care at Barris’ Emergency Care Unit (UPA), the only flu service operating so far that has tripled in demand in the past week.

    According to researcher Marcelo Gomez, Infogripe coordinator at Fiocruz, a group that monitors data for severe acute respiratory syndrome (SRAG) notifications in Brazil, the outbreak in El Salvador comes from a new H3N2 mutation that appeared in the northern hemisphere at the end of last year that arrived in Rio de Janeiro, In the second semester, it spread to other states, such as Bahia and Amazonas.

    “Today, we already know that H3N2 predominates, even without genetic sequencing, because in addition to Rio de Janeiro with an epidemic scenario, it ends up spraying in the capitals and large centers of the country, because of our air network. We have, daily, passengers going up from Rio to the main cities In the country and vice versa.. Gomez says this causes a very high incidence of cases in Rio, which is certainly the same type...

          "Brazil is experiencing a flu scenario predicted for fall 2022"
          Bruno Lupion
          4 hours ago4 hours ago

          Vaccine applied this year does not protect against the Darwin strain of the H3N2 virus in circulation, and severity is similar to that of flu from previous years, says specialist. Anticipation of the outbreak caught the unprotected population.

          Some regions in Brazil are facing an outbreak of influenza, the common flu, caused by a new strain of the H3N2 virus. The epicenter is the Metropolitan Region of Rio, where it was declared an epidemic state, but the number of new cases is also growing in other places, such as in the states of São Paulo, Minas Gerais, Espírito Santo and Bahia.

          Last Tuesday (12/14), the municipal health secretary of São Paulo, Edson Aparecido, acknowledged that there was an "outbreak" of flu in the city. Accurate monitoring of new cases, however, is hampered by instability in federal registration systems.

          The new strain was named Darwin, the name of the city in Australia where it was first identified this year. It will be considered in the formulation of the 2022 flu vaccine, which should begin to be distributed in Brazil in February or March.

          Physician Isabella Ballalai, vice president of the Brazilian Society of Immunizations (SBIm), tells DW Brazil that the flu cycle began very early this year and that the country is, in practice, experiencing the scenario "predicted for our autumn -winter 2022".

          Ballalai explains that the flu vaccine given in the first half of the year does not protect against this strain, and that the symptoms of influenza caused by the current outbreak are no more serious than the flu from previous years, but they do require care...

          ...DW Brazil: Why is the flu outbreak happening in the summer this year?

          Isabella Ballalai: It's a question that doesn't want to be silenced. We don't have scientific evidence to say exactly why this is happening, but there are some suspicions and considerations. First, the influenza virus circulates year-round in Brazil, not just during seasonal months. In most parts of the country this happens in the fall and winter months. But in Northern Brazil the seasonality is anticipated, in December and January is when it starts there.

          It's the first time we've seen such anticipation. It already happened in 2016, when the influenza outbreak in Brazil began in January and February. It was a year of a lot of circulation of the virus and a lot of chaos, as the anticipation caught everyone unprepared, since the vaccine in Brazil arrives in February and March.

          Another factor is the use of a mask, which greatly reduces the transmission of influenza. So we have a population that was not exposed to the virus, even though it was circulating among us. People were locked in the house or going out little, and wearing masks and hand hygiene care and so on. These barriers increase the number of susceptible people, who are people who have had no or little contact with the virus.

          And this year we had one of the worst vaccine coverage for influenza in Brazil. Everyone was in the middle of the covid-19 campaign, much more concerned about getting vaccinated against covid-19 than against influenza. It is likely that the sum of all this led to this anticipation. The prevalent strain circulating among us is H3N2 Darwin, which was announced by the World Health Organization as one of those that will be part of the vaccine for 2022. So today we are living the scenario predicted for our fall-winter 2022...

Some municipalities are already preparing for the return of tents to deal with influenza cases. The outbreak spread across the interior and Baixada Santista, and was exacerbated by the further spread of H3N2 virus variant, which the vaccine has not yet combated. Municipalities designate health units for the exclusive care of patients with influenza-like symptoms.
