I'm at the tail end of it now. Or at least I hope I am.
It started about three weeks (wait, is it four?) ago with a high fever, migraine, back aches, and fatigue. Then a few days later I started getting a bit of a soar throat, and a few days after that I lost my sense of smell and taste in about a day -- and that's when I knew. A few days later I took a test which four days later came back positive.
My wife and daughter were both sick as well. My wife's symptoms mimicking mine, but offset by two days. My daughter, well... kids are invincible, also being 3 she lacks the vocabulary to communicate much more than this and that hurts. She had a fever and a head ache for a few days.
The fever, migraine and bed rest lasted about a week and a half.
They were both given the all clear last week, while I got put on antibiotics and an inhaler because I was displaying some indications that it was migrating to my lunges. I seem to be in the clear now.
I'm 38 and a C level exec at a startup in a critical phase, and I am afraid to say that I've been defunct since this thing started. The fatigue has been crushing. But it seems to be mental fatigue and not a physical one (well, after the first week at least). I've been doing gardening and started a gazebo construction project while this was going on (being idle makes me go a bit nuts), sweating like a manic under the sub-tropical sun, but I've hit brick walls as soon as I've tried to focus on anything more complex than "man beat tree, tree fall down".
I can't focus on anything complex for more than a little while. Today I stubbornly started debugging an issue, but after my initial findings, and realizing it was a slightly complex problem, I had to hand it over to a coworker as I was completely wrecked after 10 minutes of focusing -- and this was the most work I've done in weeks.
I see some improvement every day, but it is very frustrating not being able to get any real work done.
It's scares me that it has had this big effect on me even if I had a comparatively mild case. I can't imagine what other people are going through.
