A new type of coronavirus believed to have originated in dogs was detected among patients hospitalised with pneumonia in 2017-2018, and may be the eighth unique coronavirus known to cause disease in humans if it is confirmed as a pathogen, a study said.
Researchers in the study, published in the Clinical Infectious Diseases journal on Thursday, said their findings underscored the public health threat of animal coronaviruses.
The researchers said they had tested nasal swab samples taken from 301 pneumonia patients at a hospital in the east Malaysian state of Sarawak. Eight of the samples, mostly from children under 5 years old, came back positive for a canine coronavirus.
Further genomic sequencing found that the new strain, named CCoV-HuPn-2018, shared characteristics of other coronaviruses known to have infected cats and pigs but was mostly similar to one that is known to have infected dogs.
