A person connected to one of Amazon's warehouses in New Castle has tested positive for the coronavirus, the company confirmed.

Amazon spokesman Timothy Carter did not say whether the person is directly employed by the company at the warehouse or is a partner delivery worker. He also did not say when the case was discovered.

"We are supporting the individual who is recovering," Carter wrote in a statement. "We are following guidelines from health officials and medical experts, and are taking extreme measures to ensure the safety of employees at our site."

An Amazon representative said employees at the logistics center at 1500 Johnson Way have been told about the case. Employees who were in contact with the person at the building will be given two weeks of paid leave to self-quarantine at home, the representative said.

But one delivery driver who worked for an Amazon contractor at the site told Delaware Online/The News Journal that not all workers at the building were told about the case in a timely manner.

The driver said the delivery company that employed him told its drivers on March 27 that Amazon had confirmed a case at that building on March 19, eight days earlier. The driver's name has been withheld because he feared for his future job prospects after speaking out.

The driver said the delivery company said Amazon watched a video of the person who was infected and cleaned and removed things that person touched. He was told there were no more cases at the site.

By the time he found out about the case, he said he had been inside the building for four or five different delivery shifts after the case was found. He said his "heart dropped for a second."

"So I've been in this building for multiple days now, and y'all didn't tell us?" he said of Amazon. "You've known about it. ... Amazon was not willingly sharing that information."

Attempts to reach the delivery contractor on Friday afternoon were not successful. Amazon did not respond to inquiries about whether it notified its contractors who work in the same building.

The next day, the drive quit his job, fearing being exposed to the virus and bringing it home to high-risk family members. He lives near Newark with his parents, who are older than 60; his girlfriend and infant child; and his sister, who has sickle-cell disease.

"I cannot afford to be working with people who may have this stuff," he said of the virus. "I was fortunate to be able to walk away because I have a support system around me."

He said he does not trust the building was fully sanitized after the case was discovered. It was not closed, he said.

"For you to be like, 'We watched the footage and sanitized what they touched,' shows they lack knowledge of the nature of this virus," he said. "What about all the people this associate has talked to and been around? There's no way you could possibly have sanitized all the carts from multiple shifts."

The Amazon representative said in evaluating whether buildings need to be closed for deep cleaning, the company considers how long the person who tested positive was in the building, how long ago the person was there and whether the area they were in is regularly cleaned.

The building is one of two Amazon warehouses off Route 273 and is the last stop for packages before they are delivered to customers.

Amazon went on a hiring spree to add 100,000 full- and part-time jobs as shoppers are encouraged to stay home during the pandemic. Delaware was expected to see 150 of those jobs.

Employees diagnosed with the coronavirus will receive two weeks of paid leave, the representative said, adding that health officials believe the virus does not spread through packages. Scientists in one study found that the virus can be stable on cardboard for up to 24 hours.

The representative said the company has implemented more cleaning of its buildings, rules to ensure social distancing, and requirements that employees sanitize their workstations and vehicles.
