Coronaviruses are a large family of viruses that can cause infections ranging from the common cold to Severe Acute Respiratory Syndrome (SARS). Some of the virus types cause less severe disease, while some - like the one that causes Middle East Respiratory Syndrome (MERS) - are far more severe.
“The initial information about the cases of pneumonia in Wuhan...pointed to a coronavirus as a possible pathogen causing this cluster,” the WHO said in a statement.
It added that since Chinese authorities have conducted laboratory tests and eliminated the SARS coronavirus and the MERS one as possible causes, as well as flu, bird flu, adenovirus and other common respiratory pathogens, “therefore, a novel coronavirus could not be ruled out”.
The pneumonia outbreak started last month, and 59 cases had been reported by Chinese authorities by Sunday.
