Answer:

Coronaviruses are a family of viruses that cause disease in animals. Seven, including the new virus, have made the jump to humans, but most just cause cold-like symptoms.

Covid-19 is closely related to severe acute respiratory syndrome (SARS) which swept around the world in 2002 to 2003. That virus infected around 8,000 people and killed about 800 but it soon ran itself out, largely because most of those infected were seriously ill so it was easier to control.
