Scientists can't tell yet just how deadly the new respiratory virus that's spreading the globe really is. Experts caution that as other countries struggle to contain clusters of cases, there will be a learning curve.

WASHINGTON — Scientists can’t tell yet how deadly the new virus that’s spreading around the globe really is — and deepening the mystery, the fatality rate differs even within China. There’s nothing different about the virus from one place to another. Instead, the never-before-seen strain of coronavirus struck Wuhan fast — before anyone knew what the illness was — and overwhelmed health facilities. As is usual at the beginning of an outbreak, the first patients were severely ill before they sought care, Aylward said.
Still, Aylward expressed frustration at people saying: “‘Oh, the mortality rate’s not so bad because there’s way more mild cases.’ Sorry, the same number of people that were dying, still die.”Until the past week, most people diagnosed outside of China had become infected while traveling there. Aylward cautioned that authorities should be careful of “artificially high” death rates early on: Some of those countries likely are seeing the sickest patients at first and missing milder cases, just like Wuhan did.A cousin of this new virus caused the far deadlier severe acute respiratory syndrome outbreak in 2003, and about 10% of SARS patients died.
