The French Academy have declared that Covid-19 is officially feminine so should be used with the article "la".
COVID is an acronym of which the operative word is "disease". The french word for disease (maladie) is feminine. Therefore, the acronym is feminine.
Phew, couldn't sleep worrying about it. Can nod off now....
With all due respect to the Academie Francaise, that does not make any sense... virus is masculine. Le virus. So logically, it should be le Covid-19.
the main word in COVID (coronavirus disease) is disease, which is maladie, a feminine word.
Shock shock horror horror , the female of the species is more deadly than the male.
