CNN —About half of the US – 22 states, along with Washington, DC, New York City and Puerto Rico – is reporting high or very high respiratory illness activity, as flu season sweeps through the country weeks earlier than usual.
“Among the people who study flu, there’s a little saying: ‘If you’ve seen one flu season, well, you’ve seen one flu season,’ ” said Dr. William Schaffner, a professor in the Division of Infectious Diseases at Vanderbilt University Medical Center and medical director of the National Foundation for Infectious Diseases.
Although the numbers are especially high for this time of year, experts say the trends are otherwise following an expected pattern, and the early arrival of flu season doesn’t necessarily mean it will last longer or be more severe.
It’s not like we’re seeing a lot of hospitalizations without a lot of illness.”Flu activity has been highest in the South, CDC data shows.
And millions fewer flu vaccines have been distributed this season than at this point in previous years.
