Common truisms I've heard (especially in Feb-March, but still occasionally these days) is that "worry and panic is worse than the disease itself" or that "the most important messaging during a pandemic is "don't panic.""
It's relatively easy for me to find examples of significant potential harms of excess panic (eg, anxiety, agoraphobia and other psychological issues, fear of going to a hospital for other emergencies, racially motivated or otherwise outgroup violence).
But when I look at historical examples of actions during pandemics, it was hard to find *any* examples of lots of additional people dying or a pandemic otherwise made much worse by excess panic, while it was comparatively common to find examples of pandemics made much worse by insufficient worry (NunoSempere has a list here).
If there are historians or history buffs among this group, I'd love to see people provide counterexamples illustrating when excess panic makes pandemics much worse.
Well, it's quite naturally people experience anxiety because of the current situation. I also think we are still to face major economic and health care changes. It occurs we already have a high unemployment rate and health system problems. Even now people become vulnerable to alcohol, drugs, and other stuff, as well as mental illness progression. According to this blog https://addictionresource.com/ the number of addicted people is increasing.
