The 2024-2025 flu season has reached alarming levels globally, with both the United States and Italy reporting significant surges in cases and complications. In the US, the Centers for Disease Control and Prevention (CDC) reports this season as the most severe in at least 15 years, with an estimated 24 million illnesses, 310,000 hospitalizations, and 13,000 deaths since October 1.

Italy faces similar challenges, with nearly 10 million cases reported since the season began, leading to increased emergency room visits and hospitalizations. The situation has particularly strained healthcare systems in both countries.

Severity and Impact

The CDC data shows that 43 states are reporting high or very high flu activity, with the most severe cases concentrated in Texas, New Mexico, Nebraska, Michigan, Ohio, Tennessee, South Carolina, New Jersey, New Hampshire, Massachusetts, and New York City.

The impact on communities has been substantial, forcing some schools to temporarily close. In one example, the Godley Independent School District in Texas had to shut down after nearly 700 students and staff were absent in a single day.

Pneumonia Concerns

Distinguished virologist Fabrizio Pregliasco highlights three key symptoms of pneumonia to watch for: elevated heart rate, breathing difficulty, and a worsening cough that shifts from dry to producing phlegm.

Prevention and Vaccination

Despite health officials' recommendations for annual flu shots for everyone over 6 months old, vaccination rates remain concerning, with only 44% of adults and 45% of children receiving flu shots this winter.

Emerging Concerns

Health authorities are also monitoring reports of Human Metapneumovirus (HMPV) in China. While this virus has been known since 2001, it presents similar symptoms to the common cold and remains at pre-pandemic levels.
