AURORA (Colo.) — The Colorado Department of Public Health and Environment reported an outbreak at an Amazon fulfillment center in Aurora, citing 9 confirmed cases of COVID-19 at the site.

According to data collected by CDPHE, the outbreak at the Amazon center is one of 264 outbreaks in Colorado. CDPHE defines an outbreak as two or more cases at a facility.

Earlier this month, Amazon’s CEO Jeff Bezos said Amazon would be investing much of its operating profit this quarter in COVID-19 related expenses like personal protection equipment for employees and raising employee pay.

In April, Amazon announced it would use thermal cameras to check temperatures of employees working at its operating centers.

Amazon came under fire after it fired an employee who organized a protest because of concerns about the spread of COVID-19 at a Staten Island warehouse.

“This involved just three individuals, two of whom live together, and all three are quarantining at home with full pay. Our top concern is ensuring the health and safety of our employees, and we expect to invest approximately $4 billion from April to June on COVID-related initiatives to get products to customers and keep employees safe. This includes spending more than $800 million in the first half of the year on COVID-19 safety measures, including implementing over 150 significant process changes—from enhanced cleaning and social distancing measures to new efforts like disinfectant spraying. We’ve also distributed personal protective gear, such as masks for our employees, and implemented disinfectant spraying and temperature checks across our operations worldwide.”
