weren't MERS and SARS a type of coronavirus themselves? They pop up every once in a while

Coronaviruses were first discovered in the 1930s
Human coronaviruses were discovered in the 1960s. The earliest ones studied were from human patients with the common cold, which were later named human coronavirus 229E and human coronavirus OC43.

The Flu (Influenza) affects the whole body, corona the upper respiratory tract.
