This prophecy speaks of a time when a virus (it looks like that was Covid19) will arise and appear terrifying, but will actually be completely demure.  However, a second one will come after it that will truly be deadly, and will kill a LOT of people, and become a true pandemic.  I'm also including prophecies of other plagues, viruses and diseases that are unrelated to the lesser/greater prophecies as somewhat of an umbrella entry.
