Have you caught back to back colds/flu?

I’ve caught a cold (could be Covid) four times in six months. I sometimes (rarely) work in a hospital environment so that doesn’t always help, but honestly, this is ridiculous and relentless.

One of them was brutal and I’m sure it was Covid because I lost my taste buds and smell but the rest were bog standard colds.

Is it just me or is anyone catching back to back colds?
