Several Brazilian states have started to decline in the incidence of Severe Acute Respiratory Syndrome (SARS) in children, according to the Infogripe Bulletin of the Oswaldo Cruz Foundation (Fiocruz).
Between April 17 and 23, of the 3,500 SARS cases, about 1,700 were in children aged 0 to 4 years. The beginning of a decrease in cases in the child population is already reflected in the fall of the national curve. The study was based on data entered into the Influenza Epidemiological Surveillance Information System (Sivep-Gripe) until April 25.
The bulletin indicates that 44.3% of all SARS cases in the last four weeks are associated with respiratory syncytial virus (RSV), which mainly affects babies. Laboratory data indicate the predominance of cases associated with RSV in the age group 0 to 4 years; and rhinovirus and Sars-CoV-2 in the group aged 5 to 11 years.
The numbers, according to experts, indicate the formation of a plateau and the beginning of a decline in almost every country. Covid-19 cases maintain a drop among positive laboratory results for respiratory viruses, corresponding to 35.4% in the same period.
In the last four epidemiological weeks, the prevalence among cases with a positive result for respiratory viruses was 2.3% Influenza A, 0.4% Influenza B, 44.3% respiratory syncytial virus, and 35.4% SARS-CoV- 2 (COVID-19). Among the deaths, the presence of these same viruses among the positives was 4.8% Influenza A, 0.0% Influenza B, 9.5% respiratory syncytial virus (RSV), and 78.1% SARS-CoV-2 ( COVID-19).
Until epidemiological week 16 (SE16), which covers the period from April 17 to 23, 10 of the 27 federation units showed signs of growth in SARS cases in the long-term trend (last six weeks): Acre, Alagoas, Maranhão , Mato Grosso do Sul, Pará, Paraná, Rondônia, Roraima, Rio Grande do Sul and Santa Catarina.
The others point to a sign of decline or stability in the long-term trend. However, Amazonas, Amapá, Espírito Santo, Paraíba, Rio Grande do Norte and Sergipe show signs of growth in the short-term trend in the last three weeks.
According to Fiocruz, in all regions that show some sign of growth, data by age group suggest that this is a scenario restricted to the child population (0 to 11 years old). This scenario has continued since February of this year. Among the adult population, SARS cases follow a sign of decline or stability.
capitals
Ten of the 27 capitals showed signs of growth in the long-term trend up to SE16: Belém, Campo Grande, Cuiabá, Curitiba, Florianópolis, Maceió, Porto Alegre, Porto Velho, Rio Branco and São Luís. Aracaju, Boa Vista, João Pessoa, Manaus, Palmas, Recife and Vitória show signs of growth only in the short-term trend.
