Wyoming's early flu season is getting more intense. State health officials recorded more than three times more flu cases by Dec. 1 than usual.

The Associated Press reports that the state recorded 342 cases of influenza by Dec. 1. Wyoming usually reports less than 100 cases so far by this time.

Wyoming's first flu cases were reported in October. This flu season has come early all over the nation, with 48 states confirming cases by the end of November.

The Wyoming Department of Health says that flu cases in Wyoming typically increase around the end of December or early January. Health officials say most everyone should get flu shots, especially those at high risk of developing complications from the flu.

In a poll taken by Townsquare Media earlier this fall, 50% of respondents said that they planned to get a flu shot this year.  Just over 7% said they had not yet decided.
