My sons nursery teacher had a weird virus in December; high fever, some cough etc. He’s very young and fit and his doctor couldn’t get a handle on what it was because it was lingering - in the end he was diagnosed with pneumonia via x-ray- but hadn’t reported any breathing difficulties beyond the cough- much as covid patients do.
Around the same time DS and I were ill- he was okay-ish- I was so ill that I couldn’t start back at work in the NY. I had a crashing headache for a week, brain fog, exhaustion and lost some hearing in one ear. I haven’t been 100% “well” since January - heart palpitations, low energy, abdominal pain with no obvious cause and my periods have been WILD, having never previously had a problem.
We’ll never know I guess, whether it was Covid then, or if we’ve had it since, but I’ve heard enough stories from friends in medicine and pharmacology about weird viruses and inexplicable illnesses around Christmas, and teachers with whole classes out with “viruses” before the Christmas hols, that I’d be hugely surprised if it hadn’t been around last winter.
