Seven pediatric deaths have been reported to CDC so far this season, according to the agency. The latest pediatric influenza-related death, reported last week, was associated with an influenza A infection. The other pediatric deaths have been associated with a mix of H1N1, H3N2 and influenza B virus infections.
Influenza A is one of four types of influenza viruses and is the most common flu type. H1N1 is a subtype of influenza A.
This time of year is typically when the CDC begins to see an increase in flu activity.
Georgia, Alabama, California, Delaware, Massachusetts and New York have reported widespread flu activity, with another 37 states reporting either local or regional outbreaks of flu, the CDC reported.
Georgia and Colorado have reported the largest numbers of flu activity. States with “moderate” activity include Alabama, Arizona, Arkansas, Kentucky, Louisiana, Missouri, New Jersey, South Carolina, Virginia and New York City.
According to the CDC, most of this season’s flu activity has been driven by illness in school-aged children. Hospitalization rates among children younger than 5 years old are now the highest among all age groups, the agency reported.
The CDC tracks information about the spread of the flu using data sent from state health departments to create and maintain an influenza surveillance map. The map shows the number of flu cases reported to each state's health department and where the flu is hitting the hardest.
Below are the links to each state's health department, where localized information about influenza can be found. Click on the website and look for a listing called "Surveillance Reports," or "Surveillance Maps," then look for the week's report to give you the latest information.
