The expansion of the virus is large, although it has been observed in many states of the North and Northeast. Influenza shows that influenza is mainly responsible for the death of elderly by acute acute respiratory syndrome (SRAG). In addition, it is one of the three main causes of death by syndrome in children.

The increase in the new report of the Todos for Health Institute (ITP), manufactured from the data of private laboratories, has also been shown.

According to the document, the number of positive exams for influenza increased to 13 percent points between April 12 and May 17, which reached 31% – which has been the largest increase in the country since September 2022, and the presence of 42% of the virus.

According to the Institute, the largest percentage of 5 to 9 years (41%) and 10 to 19 years (40%) were the largest positive.
