An Amazon employee working at a Greenville delivery station has tested positive for COVID-19, a spokesperson for the massive online retailer confirmed to The Greenville News Thursday.

Amazon has notified other employees and delivery associates at the 744 Frontage Road building of the confirmed case, and the company has asked those who may have had close contact with the employee to stay home, Amazon spokesperson Timothy Carter said in an email.

Carter did not immediately respond to additional questions about whether the Greenville delivery station was shut down for any length of time.

He said based on most current Centers for Disease Control and Prevention guidance, there is no evidence that COVID-19 is being spread through packages.

Amazon has implemented a series of preventative health measures for employees and delivery partners at sites around the world, including increasing the frequency of cleanings at all sites, Carter said.

Those who had contact with the employee in Greenville have been told to self-quarantine at home and not return to the site until after the quarantining period, Carter said. Those employees are being paid while in quarantine, Carter said.

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

Additional safety measures being implemented by Amazon include asking employees and associates working for delivery service partners to sanitize their work areas and vehicles at the start and end of every shift. The company has also asked employees to forgo non-essential travel, stay home and seek medical attention if they are not feeling well. Amazon has adjusted its attendance policies to support this, Carter said.

Delivery associates are being told refrain from shaking hands or having any physical contact with customers, and to maintain a one-meter distance from customers during deliveries.

Amazon uses a variety of third-party companies called delivery service partners to get Amazon orders to customers in local markets.

Treadmark Logistics, Spur Logistics and Dunamis Coalition are three that serve the Upstate and frequent the Greenville station, according to their company websites.

Tim Isaacson, a delivery driver for Dunamis Coalition who lives in Anderson, said the Dunamis drivers were made aware of Amazon's employee testing positive at the Greenville center on April 1 though the employee's last day at work was March 22, he said.

Isaacson said drivers are worried safety measures have been inadequate and that staff are being told to keep coming to work or risk termination.

"To me, if someone tested positive for coronavirus, we should have been notified immediately and that facility should have been shut down for a few days and had a proper cleaning," he said. "That facility wasn’t shut down and cleaned thoroughly. That guy could have walked all over that dang facility."

Isaacson said his colleagues are worried about contracting the virus and spreading it to the community.

"Nobody wants to go in there but our hands are forced," he said.

Dunamis Coalition owner Tim Hall did not immediately return a phone call seeking comment.

The other local delivery service partners did not immediately return phone messages and emails.
