England's chief medical officer says there is a global shortage of coronavirus tests

There is a global shortage of coronavirus tests, causing a "bottleneck", England's Chief Medical Officer Chris Whitty said on Wednesday.

"We do not have sufficient testing and this is a global problem because basically every country is wanting this new test, for a disease that wasn't actually being tested for anywhere three months ago," Whitty said at a daily news conference.

"So everybody wants this, so there is a global shortage and that's a bottleneck for us."
