According to Fiocruz, the incidence in children has grown a lot since February, showing the formation of a plateau and now begins a decline.
On the other hand, the analysis warns that the percentage of Respiratory Syncytial Virus (RSV) cases continues to increase, which reached 41.5% of the total SARS cases registered in the last four weeks, even though the disease is mainly observed in children.
In the 0-4 age range, laboratory tests indicated 66.4% of RSV, falling to 23% in the 5-11 age range. In national data for all ages, there is stabilization in adult age groups, with positivity of 36% for rhinovirus and 28% for Sars-CoV-2 (covid-19).
