The Infogripe bulletin, published today by the Oswaldo Cruz Foundation (Fiocruz) today (12), shows signs of an increase in acute respiratory syndrome (SARS) among the adult population in several Brazilian states. The data show that Covid-19 is the main cause of the increase.
The newsletter covers the period 1-7. May and is based on data entered into the Influenza Epidemiological Surveillance Information System (Siep-Gripe) up to 9 this month.
The new bulletin shows that the upward trend in cases highlighted in last week’s report continues. The estimate is 5,000 cases on average in the first week of May, which is more than the 4,700 cases in the last week of April.
According to the bulletin, in general, most cases, accounting for 41.2% of the viruses tested, are respiratory syncytial virus (RSV), which is basically restricted to young children. Adults have Sars-CoV-2, which causes covid-19, accounting for 37% of all cases.
The study shows that 17 of the 27 federal units show signs of an increase in SARS cases over a long-term trend over the last six weeks: Acre, Alagoas, Amazonas, Amapá, Ceará, Maranhão, Mato Grosso do Sul, Mato Grosso Grosso, Pará, Paraná, Rio de Janeiro Janeiro, Rio Grande do Norte, Rondônia, Roraima, Rio Grande do Sul, Santa Catarina and Tocantins.
In Minas Gerais, there are signs of growth only in the short-term trend of the last three months.
Infogripe also shows that covid-19 is the leading cause of death (81.6% of cases); then RSV (8.5%), influenza A (2.8%) and influenza B (0.7%).
