COVID-19 is spread through human-to-human transmission.
We already know a lot about other viruses in the coronavirus family and most of these types of viruses have an origin in animals. The COVID-19 virus (also called SARS-CoV-2) is a new virus in humans. The possible animal source of COVID-19 has not yet been confirmed but research is ongoing.
WHO continues to monitor the latest research on this and other COVID-19 topics and will update, as new findings are available.
