Someone who has elevated COVID-19 prevention or mitigation to the point of a religious persuasion, like they have become a zealot and judge and shame others for their “lesser” measures. A COVIDIAN does everything with COVID-19 prevention in mind, especially for others to see.
“Look at those two COVIDIANS! They live in the same house, but they’re social distancing on their daily walk together!” Or, “I wash my hands frequently and wear a mask , but I’ve not gone off the deep end and become a COVIDIAN or something like that!”
The far left zealots that believe everyone should worship a disease and give up their life in fear of it. The kind of people that approve of locking people in their homes and taking away freedoms.
