Contemporary similarity: Two photos from 1920. There was a flu pandemic that year.
Apart from superficial similarities the pandemic 100 years ago was a very different beast than the current one -- for a whole number of reasons, not least the fact that it erupted after many years of war.
That said, the 20-20 thing is... uhm... remarkable, to say the least. But then the timing is not the only thing about the current pandemic -- and the whole situation that surrounds it -- that is a bit odd. To say the least.
