"Coronaviruses are known to circulate amongst humans but also other animal populations and particularly bats, and there are also other types of animals that can also carry coronaviruses," Dr Lisa Maragakis, senior director of infection prevention at Johns Hopkins School of Medicine, tells Al Jazeera.
