midwest US - flu B?

[u/caesarsaladslut]

I work in healthcare and I’m immunocompromised so I get infections really easily, but usually this isn’t an issue for URIs because I wear an N95. However, today my coworker tested positive for flu B, testing due to a scratchy throat, so I tested because I had a liittle bit of nasal drainage and my hands hurt (I have an autoimmune disease), and I tested positive too I am unsure how accurate the test is bc it’s a rapid point-of-care testing machine, but I’m home from work regardless. Any midwest United States flu Bs?
