The alert came after some customers in cities like Redmond, Washington, reported extremely long wait times for Amazon's Prime Now service last week, CNBC reported. Washington is the state hardest hit by the coronavirus outbreak and has reported 16 deaths.
On the other side of the country, New York Gov. Andrew Cuomo declared a state of emergency on Saturday as the state’s number of confirmed coronavirus cases rose to 76, with 11 of them in New York City.
The declaration of emergency will allow state officials to expedite the process of purchasing supplies and the hiring of workers to assist local health departments that have handled and monitored thousands of quarantined patients, Cuomo said.
