In NZ we had a period of lockdown during which colds and flus were non-existant and then we went completely back to normal life for a while.

In that winter after the lockdown we had an absolutely ferocious amount of colds and flus all of a sudden.

I had 6 back-to-back. It was 12 weeks of hell. Every other person I know had at least 2. Parents (such as myself) all had 4+ colds/flus in a 3 month period.

There was a lot of speculation that the spread was significantly worse because it got into a population entirely made of people who had not been sick for a while.

So you might have that to look forward to.
