In the current US flu season, over 18 million cases have been reported, with 230,000 hospitalisations and 9,300 deaths. Influenza A (H3N2) is the dominant strain. Most affected children were unvaccinated. Flu spreads via coughs and sneezes, and vaccination remains the most effective prevention, while treatment focuses on symptom relief and hydration.
