I don’t remember school closings from flu growing up in the 90s. Never saw the student body at half capacity with so many people out sick. Maybe we’re more hearty in the Midwest. But no references in pop culture shows or movies from the past 20 years make me think this was commonplace elsewhere. Maybe some experimental shot a bunch of people took is flattening their immune systems.

It didn't use to happen, just in the last 4-5 years.
