Amazon has temporarily closed some sites, such as the Queens location, but has largely refrained from mass closures. The company says they are “Taking extreme measures to ensure the safety of employees at our sites”.

That includes regularly sanitizing door handles, elevator buttons, lockers and touch screens, as well as staggering shifts and spreading out chairs in break rooms.

The spread of the virus within Amazon’s massive logistics operation may only add to the anxiety among workers who have previously said they felt Amazon should be doing more to protect the hundreds of thousands in its warehouse facilities across the US.

The additional cases also threaten to disrupt shipments and delay deliveries even as millions of Americans are becoming more reliant on the service as they are told to leave their homes as little as possible. The company is already warning visitors to its website of longer delivery times and encouraging customers to select no-rush shipping if their needs are not urgent.

Amazon is witnessing spikes in demand that are comparable to the surge surrounding peak holiday periods such as Black Friday, says Jay Carney, Amazon’s senior vice president of global corporate affairs.

“We’re boosting employment by 100,000 in the way that we do for seasonal periods like the holiday, when we need extra workers,” Carney said.

One worker at the Staten Island facility told CNN Business that despite confirming the positive case to the media, Amazon had not notified workers at the site through email, text message, call or update in the company’s employee app — pointing to a lack of internal transparency.
