Answer 1

Explanation:

Official names have been announced for the virus responsible for COVID-19 (previously known as “2019 novel coronavirus”) and the disease it causes. The official names are:

Disease

coronavirus disease

(COVID-19)

Virus

severe acute respiratory syndrome coronavirus 2

(SARS-CoV-2)

Why do the virus and the disease have different names?

Viruses, and the diseases they cause, often have different names. For example, HIV is the virus that causes AIDS. People often know the name of a disease, but not the name of the virus that causes it.

There are different processes, and purposes, for naming viruses and diseases.

Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).
