Then why aren't these other diseases pandemics aside from the coronavirus? Also if you get the coronavirus naturally and recover from it, you'll have lifelong immunity. Besides, band-aids smell like crap!
There are plenty of pandemics and things approaching that line.
There was a flu in the late 1950s that came close, the 1918 Spanish flu is another.
More to plants and animals and you have any number. Prior to this Kung Flu lark then China's pigs were dead and dying at a bit enough rate there was a massive pork shortage (and when your word for meat means pork, everything else being a modifier like some other languages might use apple to describe various fruits and vegetables -- pine apple, a ground apple (pomme de terre in French) then you are in trouble. CJD-BSE in cows is a fun one (and also went into humans) but is more a protein based affair (albeit a transmissible one and one monstrously hard to kill -- you throw your surgical tools away as the heat and radiation can't get it), we probably also have another version of that likely to hit deer before too long (deer being a food source for plenty of people).
HIV-AIDS qualifies in various places as one (thousands of deaths, illnesses and more caused by it)
Smallpox was eradicated save for those things stored in labs. This was 1980 it was declared done. Prior to that... thousands of years it had run around killing loads of people.
Back on not humans then plenty of things go around killing plants and trees or rendering them useless. Dutch elm disease, various moulds on wheat, insects can be an issue, potato blight (if you ever look at a potato in a gardening or farming supply scenario it will have its blight resistance as part of the key details)... Ever wondered why banana sweets don't taste like bananas? Trick question as they do, however the bananas they were based on were wiped out by a disease and they had to switch to another type.
As far as lifelong immunity. There is some debate over that. You also have the "if" problem -- plenty do die, spending a month hooked up to a tube is very expensive and takes a long time to recover from, you may have other lasting effects both in terms of damage to organs and unknown future issues (see post polio syndrome and cancers a lot of polio sufferers got in later life -- it has been less than a year at this point so we don't exactly have data there). Depending upon how you want to play it then it could also evolve to reinfect people (the common cold is a master at this, as is HIV, part of the reason we don't have vaccinations for either) and it does not mean just a round two -- the same virus that causes chickenpox (which is quite serious in adults by the way) also causes shingles in later life (an often chronic and debilitating condition affecting nerves and skin), and the same virus that causes cowpox (a mild disease) also causes smallpox (one that likely will kill you but if not leave you seriously scarred if scars are somehow a thing you care about extremely). Now whether the measures taken for this kung flu business are too much, too slow, not enough, ineffective or the like is a different matter.
I don't disagree on band aids. However what has that got to do with anything?
