Flu-like activity is up in some parts of the United States, according to the Centers for Disease Control and Prevention.The CDC publishes data on influenza-like activity by state weekly. Flu activity levels are calculated by measuring the proportion of outpatient visits to providers that have “influenza-like” illnesses. The average percentage of visits is compared to noninfluenza weeks.Because the CDC does not track flu-positive tests, flu-like activity may include other respiratory illnesses with similar symptoms. Data also does not capture trends within a state, just for the state overall, plus Washington, D.C.The Get the Facts Data Team is tracking how much influenza-like activity there is by state and how it changed from the week before.The charts below will update weekly on Fridays, when CDC data is updated.PHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPiFmdW5jdGlvbigpeyJ1c2Ugc3RyaWN0Ijt3aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcigibWVzc2FnZSIsKGZ1bmN0aW9uKGUpe2lmKHZvaWQgMCE9PWUuZGF0YVsiZGF0YXdyYXBwZXItaGVpZ2h0Il0pe3ZhciB0PWRvY3VtZW50LnF1ZXJ5U2VsZWN0b3JBbGwoImlmcmFtZSIpO2Zvcih2YXIgYSBpbiBlLmRhdGFbImRhdGF3cmFwcGVyLWhlaWdodCJdKWZvcih2YXIgcj0wO3I8dC5sZW5ndGg7cisrKXtpZih0W3JdLmNvbnRlbnRXaW5kb3c9PT1lLnNvdXJjZSl0W3JdLnN0eWxlLmhlaWdodD1lLmRhdGFbImRhdGF3cmFwcGVyLWhlaWdodCJdW2FdKyJweCJ9fX0pKX0oKTs8L3NjcmlwdD4=
