Etymology

The word "novel" indicates a "new pathogen of a previously known type" (''i.e.'' known family) of virus. Use of the word conforms to best practices for naming new infectious diseases published by the World Health Organization (WHO) in 2015. Historically, pathogens have sometimes been named after locations, individuals, or specific species. However, this practice is now explicitly discouraged by the WHO. The official permanent names for viruses and for diseases are determined by the ICTV and the WHO's

At the beginning of the COVID-19 pandemic in Hubei a 2020 study from the University of Alabama at Birmingham found a more than ten-fold increase in use of expressions such as "Chinese virus" or "Wu flu virus" on Twitter compared to before the outbreak. The researchers voiced concerns whether such terminology could hinder public health efforts or be stigmatizing. No such effects were observed in the wake of the MERS outbreaks being referred to as "Camel flu virus" or "Middle East virus".
