Disease names and classification are managed by the World Health Organization (WHO) International Classification of Diseases and follows best practice guidelines for the naming of new infectious diseases in humans. In brief, disease names are intended to quickly provide information on symptoms, causal pathogens, and other information relevant to their control and prevention.
Expert virologists are responsible for naming new viruses and the International Committee on Taxonomy of Viruses is responsible for determining the species. A consensus statement on the naming and taxonomy of the virus responsible for COVID-19 was recently published.
