Why do the virus (SARS-CoV-2) and the disease (COVID-19) have different names?
Viruses are named based on their genetic structure, to facilitate
the development of diagnostic tests, vaccines and medicines,
by the International Committee on Taxonomy of Viruses (ICTV).
Diseases are named to enable discussion on disease prevention,
spread, transmissibility, severity and treatment by WHO, and so
diseases are officially named by WHO, in the International
Classification of Diseases (ICD).
ICTV announced, “severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2)”, as the name of the new virus on 11 February 2020.
WHO announced, “COVID-19”, as the name of this new disease
on 11 February 2020.
