The US faced the ‘worst’ influenza in the past 15 years

The reason is that the winter weather lasts and the second wave of the virus causes the number of infections to increase rapidly, CDC said.

According to the week’s week of influenza surveillance, 7.8% of medical examinations are due to respiratory diseases, the highest level from H1N1 influenza pandemic in 2009. Most of the influenza indicators are increasing, including positive influenza test ratio (31.6%), the number of patients hospitalized this week (48,661 cases) and influenza mortality rate (2 2 %).

“The seasonal flu is still high and continues to increase nationwide,” CDC said.

For the first time in the flu season this year, the seriousness is considered to be “very high”, while the number of Cover-19 cases is decreasing each month. The most heavily influenced states include Texas, Oklahoma, Florida, South Carolina, Kentucky, Wisconsin, Pennsylvania, Maryland, Delaware, New Jersey, Connecticut and Maine. Kentucky is one of the states with the strongest level of flu -flu, with the probability of outbreak of up to 92.45%.

Dr. Kris Bryant, Deputy Health Director of the Department of Health and Community Health of Louisville Metro, said that the influenza cases have a significant impact on children in Kentucky this year, especially elementary and elementary children. Preschool.

“So far this week, more than 2,900 children have positive results, the number has increased,” Bryant said.

Dr. Bryant also pointed out that the national immunization rate has decreased annually since 2020. At the end of January, the CDC reported less than half of the country’s children have vaccinated, the lowest level in the past 6 years. In 2025, less than half of the American people were vaccinated.

The symptoms of the flu include: fever or chills; cough; sore throat; runny nose or stuffy nose; muscle pain; headache; tired. Some people may vomit and diarrhea, which is more common in children.

Tests show that the flu spreads due to the usual seasonal variable of the virus, without the new influenza strains from animals.

Besides the US, the flu is affecting many countries. In East Asia, Japan, South Korea reported the most serious outbreak in many years, causing the hospital to overload and the treatment drugs became scarce. In Taiwan, China and Hong Kong, after the death of the influenza complication of the actress Tu Hy Vien, the people rushed to vaccinate the vaccine.

Currently, the seasonal flu epidemic in Vietnam also increases with the appearance of influenza A (H1N1, H3N2) and influenza B, without abnormal strains. Many people are hospitalized with more severe symptoms than usual, especially in groups of children, elderly people and people with background disease.

The Ministry of Health recommends that people vaccinate, wear masks and enhance personal hygiene to prevent spreading. The situation of antiviral scarcity is temporarily recorded in some localities, but the supply is being supplemented.
