Just How Bad Was Flu Season Last Year? A Look at the Numbers

This post was updated on October 11, 2018


Both here in western North Carolina and around the nation, the 2017-18 flu season rose to the level of an official epidemic. As the number of flu cases continued to rise throughout last winter, many schools saw unprecedented flu-related absences and, most unfortunately, our state experienced a record number of flu-related deaths.

Last year’s record-setting flu season – which ran from November 2017 through May 2018 – is a stark reminder to always get the flu vaccine, practice proper hand hygiene, stay at home when you’re sick and seek care immediately if you have flu-like symptoms.

The numbers below from the 2017-2018 flu season illustrate just how bad the flu season was, as we compare the total number of flu cases to the previous year’s flu season. These numbers represent total positive flu tests at Mission Health facilities in WNC, specific to the time frames denoted.

  • January 2018 saw more than five times the amount of flu cases than January 2017
    • 2017: 167
    • 2018: 886
  • February 2018 flu cases were nearly double the amount in February 2017
    • 2017: 356
    • 2018: 637
  • Through March 22, 2018, flu cases were pacing nearly 300 more than the same date the previous season
    • 2017: 1537
    • 2018: 1808
The lessons from last flu season’s epidemic are nothing new. To avoid the flu, the best thing you can do is to get the flu shot. It’s also imperative to seek the appropriate medical care if you become ill with flu symptoms. Both of these steps could be life-saving.

As last year has shown us, the flu is a serious illness that is not to be taken lightly.
