It seems like there is, but I’ve been struggling with my own burnout issues more than ever before, so maybe the rate is the same as it’s always been and I’m just more sensitive.
Other than the obvious economic impacts of the pandemic on small businesses, the de-stressing activities I personally enjoy - lifting weight, martial arts, going to the cinema - have been unavailable for most of the pandemic. I think that this has led to a less well-defined stopping point at the end of each day both physically and mentally.
The knock on effect of this has been more chronic stress. Before I had a really strong demarcation between the working week and my leisure time: up until things opened up again recently (Scotland), I haven't.
Taking the dog a long walk after work each day showed promise, but it wasn't as effective as I'd hoped. I ended up just thinking/talking about work the entire time.
Thankfully, most things have re-opened here (Scotland) now so I'm able to resume all those hobbies that were sorely missed.
You really don’t see a burnout coming, but if you work all your waking hours there is a good chance you reach that breaking point.
Stability truly is key to prevent it.
There are probably some countries with population-wide burnouts and on the risk of collapse (South Africa, North Africa, Colombia, etc...)
