Actually according to Catholic.org, St. Corona is the saint of ..' Corona is invoked in connection with superstitions involving money, such as gambling or treasure hunting..' (https://www.catholic.org/saints/saint.php?saint_id=1968) The Wikipedia also says that. Corona's memorial day is 24 November (11 November in the Orthodox church calendar) though her & St Victor's feast day is May 14.
Snopes.com was asked if she was connected to plagues and diseases due to meme/conspiracy theory going around the internet. There research was - Nope. (https://www.snopes.com/fact-check/saint-corona-plagues/ . Humorously, they theorize it was created by the same 'logicians' who believe Corona beer is connected to the virus. Note- It isn't. The fact that something was named Corona, doesn't mean its connected. Or if something happens on May 14th, its doesn't mean it's connected to Israel. Many things happen on that date cause things have to happen sometime.
The Pope's meeting doesn't seem too nefarious. Matter of fact its amazingly tolerant and a 'more open and inclusive education' is one its themes. A call against discrimination and towards fraternity. Seems worthwhile, don't know if it'll actually go on due to the Virus but I applaud its goals. Not that it has much power, any more then the usual yearly such meeting does.
'To this end, I wish to endorse a global event, to take place on 14 May 2020 on the theme Reinventing the Global Educational Alliance. This meeting will rekindle our dedication for and with young people, renewing our passion for a more open and inclusive education, including patient listening, constructive dialogue and better mutual understanding. Never before has there been such need to unite our efforts in a broad educational alliance, to form mature individuals capable of overcoming division and antagonism, and to restore the fabric of relationships for the sake of a more fraternal humanity".
"There is thus a need to create an “educational village”, in which all people, according to their respective roles, share the task of forming a network of open, human relationships. According to an African proverb, “it takes a whole village to educate a child”. We have to create such a village before we can educate. In the first place, the ground must be cleared of discrimination and fraternity must be allowed to flourish, as I stated in the Document that I signed with the Grand Imam of Al-Azhar on 4 February this year in Abu Dhabi."
With a tiny bit of research, now we know the rest of the story. That if searching for treasure, Corona's available and that the Pope's meeting on May 14th, if it happens, is surprisingly inclusive and progressive.
