Fiocruz warns of an increase in SARS cases among adults in Paraná

On Thursday, December 12, the Oswaldo Cruz Foundation (Fiocruz) released a new InfoGripe Bulletin that showed signs of an increase in acute respiratory syndrome (SARS) among adults in several states. The data were recorded between the end of April and the beginning of May. Paraná is following this SARS trend among the adult population. According to Fiocruz, epidemiological data also refer to the so-called the prevalence of respiratory syncytial virus (RSV) among young children in Brazil, accounting for 41.2 percent of all SARS cases in the country.

“Cases of Sars-CoV-2 (Covid-19) suggest that the decline in reports of laboratory results positive for respiratory viruses has been interrupted, corresponding to 37 percent in the last four weeks. Respiratory syncytial virus (RSV) cases continue to account for the largest proportion of viruses tested, accounting for 41.2 percent of all SARS cases that tested positive for respiratory virus in the past four weeks, although it is essentially limited to young children, ”says Fiocruz.

Data are based on Epidemiological Week (SE) 18, which analyzes the period from 1 to 7 May. According to the data entered in the Influenza Epidemiological Surveillance Information System (Siep-Gripe) until 9.5.2022. According to researcher Marcelo Gomes, coordinator of InfoGripe, due to the sign of adult reproduction, a network of laboratories across Brazil needs special attention to identify which viruses or viruses are associated with this recent trend.

Gomes says it is essential to analyze the difference in Covid-19 cases, which he says is still the leading cause of SARS in adult lab tags. “The national SARS curve shows signs of growth in long-term (last 6 weeks) and short-term (last 3 weeks) trends. The estimate is 5.0 (4.3 to 5.8) thousand cases in week 18, ”he adds.


In the last report, Paraná, together with 16 other Brazilian states (AC, AL, AM, AP, CE, MA, MS, MT, PA, RJ, RN, RO, RR, RS, SC and TO), showed a long-term increase in SARS cases trend. “There are only signs of growth in the short-term trend in Minas Gerais. Of the capitals, 17 out of 27 show signs of long-term growth: Boa Vista (RR), Cuiabá (MT), Curitiba (PR), Florianópolis (SC), Fortaleza (CE), Goiânia (GO), Macapá (AP), Maceió (AL), Manaus (AM), Palmas (TO), Porto Alegre (RS), Porto Velho (RO), Recife (PE )), Rio Branco (AC), Rio de Janeiro (RJ), São Luís (MA) and Vitória (ES), ”he says.

“A total of 24 health care macro-regions are at pre-epidemic level, 20 at epidemic level, 65 at high level, 9 at very high level and none at very high level. In the last four epidemiological weeks, the incidence of positive cases for respiratory viruses was 2.9% for influenza A, 0.5% for influenza B, 41.2% for respiratory syncytial virus, and 37.0% for Sars-CoV-2 (Covid-19). Of the deaths in the current year, these positive viruses accounted for 2.8% of influenza A, 0.7% of influenza B, 8.5% of respiratory syncytial virus (RSV), and 81.6% of Sars-CoV-2 ( Covid-19). over the last four weeks, ”concludes Fiocruz’s advice.
