According to BuzzFeed, US Amazon workers were already worried about their risk of catching the virus at work, after warehouse workers in Europe tested positive. Workers in these warehouses tend to stand close to each other, BuzzFeed added.

Amazon has seen a significant increase in demand, as the coronavirus spreads and people stay at home and grocery store shelves are stripped empty. In fact, the company is looking to hire an additional 100,000 US warehouse and delivery workers to meet the demand.

Additionally, the company is also suspending shipments of all nonessential products to its warehouses as a way to deal with the increased workloads. Amazon will focus on shipping out medical supplies, household staples, and other high-demand products to its warehouses until April 5.

Amazon did not immediately reply to Business Insider's request for comment.
