It's one out of a large number of propaganda lines or "NPC script lines" where the ultimate goal is to convince the reader/listener to decide that we should simply stick our heads in the sand and pretend the COVID-19 pandemic does not exist.
You are lucky if you have not been exposed to this propaganda very much yet.
You might notice that the editorial reads as if the word "Covid" refers to "that time when the government told us to wear masks and get vaccines and all that stuff." I'm not sure if people actually hold this view or just pretend to, but it's not uncommon.
It's trying to give off the aura of "Oh, remember when all those silly people told us to wear masks, it was just a silly thing that happened one time, why are we still talking about it, we should just forget it ever happened."
People with attitudes similar to the author are the reason there is still a COVID-19 pandemic, in the developed world at least. I'm surprised you don't have experience with them by now.
