Flu infections in the US fell slightly in the past week, according to new government data. However, it is not clear whether the season, which is described as severe, has already reached its peak. The data released on Friday relates to flu activity over the previous week. Health officials warn that despite a slight decrease, the flu is still very widespread. The season is rated as severe based on the intensity of the spread and the burden on the health system. The data do not yet make it possible to determine with certainty the further development of the season. Health authorities continue to monitor the situation through regular data collection and evaluation.
