Feminine is what the Académie settled on, months after everyone settled on Masculine.

That institution holds some normative power with other institutions (e.g. some media outlets) but has utterly failed to impose its outdated and reactionary outlook to anyone but other reactionaries. They’re constantly coming out with revisions for words that reached common parlance years earlier.

So common usage is Le covid. If someone used the feminine I’d have to assume they unironically use the word “Wokisme”.
