I think any parallels would be few.
Yes, its a pandemic, but COVID-19 is not nearly as lethal, the symptoms not as severe, and there was simply no medical knowledge to speak of seven hundred years ago. PPE was rare and primitive, hygiene was virtually unknown, and social distancing wasn’t a practice. People were told that plague was caused by sin and spread by demons.
A notable difference in these two events is that during the Black Plague, the masses were implored to huddle into the churches to pray for their souls, which they did in droves (ironically driving up the death toll), whereas now churches all remain empty by public decree.
