Another new coronavirus has jumped to people
As the world is dealing with a pandemic caused by one novel coronavirus that likely jumped from animals, researchers have identified another novel coronavirus from a child with pneumonia in Sarawak, Malaysia, in 2017-18, reports a study today in Clinical Infectious Diseases.
Dubbed CCoV-HuPn-2018, this new virus is the first canine coronavirus (CCoV) to ever be isolated from a human.
If CCoV-HuPn-2018 is confirmed as a pathogen, it would be the eighth known coronavirus to cause infection in humans.
Shared traits with other coronaviruses
Lead study author Anastasia Vlasova, DVM, PhD, of The Ohio State University, and her team used reverse transcription-polymerase chain reaction (RT-PCR) assays, cultured the virus in A72 canine cells, and pieced together the genome using the Sanger method. The article highlights their in-depth findings, but here are a few items of note:
First, the virus is a novel canine-feline recombinant alphacoronavirus, and it shares multiple genomic traits with the widespread CCoV-II. (SARS-CoV-2, the virus that causes COVID-19, is a betacoronavirus.)
