The death toll of a coronavirus outbreak sweeping China has reached 814, with more than 37,000 people infected as of Sunday.
A man in the Philippines and a 39-year-old man in Hong Kong mark the only two deaths outside mainland China.
The virus has spread to every province and region in China as well at least 25 other countries. Both the death toll and the number of infected patients in mainland China now exceed those of the 2003 SARS outbreak there.
The zoonotic virus may have jumped from animals to people at a market in the city of Wuhan. Researchers suggest that the virus originated in bats, and one study suggests the disease might have spread from the endangered pangolin to people.
Outside China, cases have been reported in Australia, Belgium, Cambodia, Canada, Finland, France, Germany, India, Italy, Japan, Malaysia, Nepal, the Philippines, Russia, Singapore, South Korea, Spain, Sri Lanka, Sweden, Taiwan, Thailand, the United Arab Emirates, the UK, the US, and Vietnam.
The US has reported 12 cases so far, the latest of which was confirmed in Wisconsin on Wednesday.
The World Health Organization declared a public-health emergency last week, and Chinese President Xi Jinping said the virus posed a “grave threat.”
