Officials at the Centers for Disease Control and Prevention in Atlanta said reports of influenza-like-illness are nearing what have been peak levels during moderate flu seasons, but the peak for this year hasn't been reached.
During the week of Dec. 23, U.S. influenza activity increased -- of 9,363 specimens tested, 32 percent were positive for influenza. Region Five, comprised of Illinois, Indiana, Minnesota, Ohio and Wisconsin, reported the highest rate, with 58 percent of samples taken by doctors testing positive for influenza.
Two influenza-associated pediatric deaths were reported for the week and were associated with influenza B viruses. The total flu-related pediatric deaths for this season was 18.
New York City and 29 states experienced high influenza-like-illness activity: Alabama, Arkansas, Colorado, Florida, Georgia, Illinois, Indiana, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia and Wyoming.
