Saint Corona is invoked against plagues and viruses. Her Feast Day is May 14. Let us pray to St. Corona for all those sickened by the virus, our medical personnel, scientists advancing their knowledge and bringing us relief with the vaccine, and all those who have died from the virus. St. Corona, Pray for Us. Corona means Crown in Latin, which is also where the coronavirus gets its name, from the spikes of protein that form a crown around the virus. In Catholicism, the crown is a widely used emblem for martyrdom, particularly for female saints.
