It depends on their position within the global economy.
As such, a nation’s health depends on their political and economic situation. They catch colds during economic recessions.
The Great Depression strips are a good source for this, as each negative number assigned to a nation has a differential impact on their health. Since America was a manufacturing powerhouse at the time, his stock market crash affected them all.
Ex: Japan obtains a cough, meanwhile Poland runs a high fever.
In modern strips, we’re also provided with the fact that Austria will slip into a high fever and eventually collapse if Germany even so much as catches a cold.
“A reliable country that likes to approach things with a sober seriousness.
He approves of and supports lots of Germany’s ideas so he may look like one of the helper countries, but in reality the level of his dependency is pretty high.
So high that when Germany catches a little cold, Austria goes straight to high fever and eventually collapses, and so he doesn’t have much of a choice than to take good care of himself.”
As for how serious it can get? Spain almost died from an economic recession.
