Yes, Covid is a type of Corona virus. It is called a Corona virus because, under the microscope, you can see that it is in the shape of a corona (which means a crown).
The influenza virus when looked at under the microscope is in the shape of a sphere.
They have two very different types of body morphology.
True. The common cold virus is in the shape of a corona, or crown, also.
The name Covid19 comes from COrona VIrus Disease 2019 (the time the virus was first identified.)
BTW, Lysol kills them all. The can I've had for several years says it's effective against corona viruses. This can predates Covid19.
Fun internet rabbit hole: Lysol was first created as a Women's Intimate Hygiene Aid!
I know! I know!
