According to CCTV News, the latest data released by the US Centers for Disease Control and Prevention on the 7th shows that there have been at least 24 million flu cases in the United States this flu season, including more than 310,000 hospitalized cases and more than 13,000 deaths.
According to Xinhua News Agency, according to the US Centers for Disease Control and Prevention, the current level of influenza infection in the United States is at a high level, and the infection rate is on the rise. In the week ending Feb. 1, there were more than 48,000 new influenza hospitalizations and 10 new childhood influenza deaths in the United States. In the current flu season, a total of 57 childhood influenza deaths have been reported in the United States.
More than 96% of patients in the U.S. this flu season are infected with influenza A. According to the U.S. Centers for Disease Control and Prevention, at least 45 states and administrative districts in the United States are currently experiencing “high” or “very high” levels of influenza activity. The number of cases requiring emergency treatment for influenza in the U.S. is “very high” across the country. The number of flu emergency visits in most states is expected to continue to increase over the next two weeks.

CBS reported on the 7th, citing data from the US Centers for Disease Control and Prevention, that the United States is currently ushering in the second wave of infection peak this flu season, and the current level of influenza infection has reached the highest level since the influenza A epidemic in the United States in 2009.
According to the website of the US Centers for Disease Control and Prevention, the flu season in the United States usually occurs in the fall and winter, with the peak period from December to February of the following year. Annual influenza vaccination not only prevents influenza virus infection, but also prevents severe disease, and it is recommended that people aged 6 months and above get the flu vaccine every year. In addition, antiviral drugs should be started as soon as possible after influenza infection, which is especially important for people who are at higher risk of severe disease.
In addition to the flu, the number of respiratory syncytial virus and new coronavirus infections in many places in the United States is also rising. The CDC said the number of acute respiratory illness visits in the U.S. is currently “very high.” Schools in some states have been forced to close or shift to online classes due to high cases of respiratory infections among children and adolescents.
“We are now in the midst of a nationwide seasonal flu epidemic, and emergency rooms across the country are already packed.” According to Yicai, Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University School of Medicine, said.
The CDC reports that the majority of cases in the United States are caused by influenza A, mainly the H3N2 and H1N1 strains. Influenza A is more aggressive to adults and tends to spread earlier than influenza B, which can surge later in the flu season.
In addition to flu cases, cases of norovirus, coronavirus and respiratory syncytial virus are also surging in different parts of the country, according to the CDC. In the United States, the flu typically peaks between December and February, according to the CDC report. However, experts say that the 2024-2025 flu season started late and has not yet reached its peak.
“We are in the middle of the flu peak, the situation is serious, however, we will not know until a few months later if it is different from previous years.” Dr. Jason Newland, director of the Department of Infectious Diseases at Children’s Hospital of America, said.
The 2023-2024 flu season is “moderately severe,” with an estimated 40 million illnesses and 28,000 deaths, according to CDC data. “Last year, we had more than 200 children die from the flu, and it was a very bad year.” Dr. Nuland said.
