Recent reporting highlights that the United States has experienced two consecutive severe flu seasons, while the impact of COVID-19 has become more stable and predictable. Experts note that unlike seasonal influenza—which typically peaks in winter—COVID-19 continues to circulate year-round with occasional summer increases. Recent flu seasons have also been complicated by unusual influenza strains that reduced the effectiveness of annual vaccines, though widespread prior infection and vaccination have helped maintain strong protection against severe COVID illness.
