The head of Public Health said that suspected COVID cases diagnosed in primary care have maintained a “marked upward trend” for approximately five weeks, although she ruled out a worrying situation for now. “We are not above unusually high incidence levels,” Adiego stressed, insisting that surveillance services consider it especially important to monitor the curve’s evolution and compare it with previous seasons.
In fact, according to Adiego, the COVID virus had remained “practically absent” for much of the 2025-2026 season until its recent rebound.
FLU REMAINS BELOW THE EPIDEMIC THRESHOLD
The situation is different in the case of flu. Its incidence currently stands at 11.34 cases per 100,000 inhabitants, still well below the epidemic threshold, set this season at around 57.6 cases per 100,000 inhabitants. Public Health is beginning to detect a slight increase, also observed nationwide, but Aragon remains below the levels that would mark the start of an epidemic.
Last season, flu circulation began around four weeks earlier than usual and reached its peak incidence phase sooner than expected. Normally, the main peaks occur around the Christmas period, although Adiego recalled that the behavior of this virus is “completely unpredictable”.
Public Health is also monitoring developments in other regions in an effort to anticipate how the season will evolve. One case that has caught the attention of experts is Japan, where the virus has already exceeded the epidemic threshold this year and the season has again started several weeks earlier. For now, however, Aragon is not showing a similar pattern.
VACCINATION CAMPAIGN GETS UNDERWAY
Adiego stressed that the increase in respiratory infections is within the expected range for this time of year and that, as of today, there is no epidemiological emergency. The rise in COVID cases and the first upward movement in flu cases nevertheless require continued monitoring as the months in which these viruses traditionally circulate more widely approach.
The vaccination campaign against flu, COVID and RSV is specifically intended to anticipate the increase in infections and reduce both complications and hospital admissions associated with respiratory infections in the coming months.
