Global virus death toll exceeds 500,000

Another tragic milestone has been passed in the coronavirus pandemic: 500,000 deaths worldwide.

The reported tally on Sunday came from Johns Hopkins University researchers.

About one in four of those deaths - more than 125,000 - have been reported in the US. The country with the next highest death toll is Brazil, with more than 57,000, or about one in nine.

The true death toll from the virus, which first emerged in China late last year, is widely believed to be significantly higher.

Experts say that especially early on, many victims died of COVID-19 without being tested for it.

To date, more than 10 million confirmed cases have been reported globally. About a quarter of them have been reported in the US.
