A citizen of the United States of America  has died from the new coronavirus in Wuhan, China, in what appeared to be the first death of an American from the outbreak.

Few details about the American, who died on Thursday, were immediately available. The person was around 60 years old and died at Jinyintan Hospital in Wuhan, according to the United States Embassy in Beijing. Two people familiar with the matter said the person was a woman who had underlying health conditions.

“We offer our sincerest condolences to the family on their loss,” said a spokesman for the embassy. “Out of respect for the family’s privacy, we have no further comment.”

The woman’s death was likely to add to diplomatic friction over Beijing’s response to the epidemic, which has generated frustration in China and abroad.

It is also certain to raise questions over whether the Trump administration and the State Department in particular have taken sufficient action to ensure the safety of Americans in China and to aid in the evacuation of those who want to leave.
