It’s a serious issue. Especially when it’s a newly observed pathogen. It should be closely monitored.
It’s not though without precedent as its a variant of SARS and MERS so it’s known that those deadly viruses did not cause any major epidemic or catastrophic death tolls.
One reason, interestingly, that this one, called WARS by some, is considered potentially worse in terms of spread is it’s not as severe or deadly as SARS.
“WARS” == “wild-assed” respiratory syndrome, named after the wide range of predictions for virulence? ;-)
