The tech industry is mobilizing its considerable resources to attempt to support efforts against the growing global coronavirus pandemic. Over the weekend, the CEOs of Amazon, Apple and Microsoft all shared updates regarding some aspects of their company’s ongoing contributions, which range from donations of medical supplies and personal protective equipment (PPE) for frontline healthcare workers, to software projects that help track and analyze the global spread of infection.

Apple CEO Tim Cook shared on Twitter that the company has been attempting to source necessary supplies that are needed for healthcare workers both in the U.S. and Europe, and that the company is joining “millions of masks” for this use. Apple also detailed some of its other updates via earlier releases, including a $15 million donation, along with two-to-one corporate matching for all employee donations that go towards COVID-19 response.

Amazon founder and CEO Jeff Bezos provided an update on Saturday on the company’s official blog that included details about the change in Amazon’s prioritization for its warehousing and logistics operations, which now focus on essential items including daily household staples, baby and medical supplies. Bezos also reiterated Amazon’s commitment to hiring 100,000 new roles, along with raising hourly wages for fulfilment workers.

Bezos notes that while the company has “placed purchase orders for millions of face masks” that it intends to distribute to its full-time and contract workers who are not able to work from home, “very few of those orders have been filled” to to the global supply shortage. He further notes that these resources are likely to go to frontline healthcare workers first, and that the company will focus on getting them to their staff in order of priority once they become available.

Microsoft CEO Satya Nadella provided a lengthy update about his company’s various efforts in a LinkedIn post on Saturday, publishing an email he sent to all Microsoft employees for external consumption. Nadella describes some of its telehealth platform software work, as well as a number of collaborative data projects, including the John Hopkins University global COVID-19 confirmed case tracker. The Centers for Disease Control and Prevention (CDC) also released a chatbot assessment tool for COVID-19 that uses Microsoft’s health chatbot tech as its underlying framework.

Microsoft is also seeing Teams and Minecraft being used globally for remote learning iniativies designed to supplement in-perosn school closures, and it’s working on machine learning and big data projects to support global research efforts. Earlier this week, Microsoft’s Chief Scientific Officer Eric Horvitz announced that it would be providing an open research data set in partnership with colleagues at academic institutions around the world, as well as the White House Office of Science and Technology Policy and the Chan Zuckerberg initiative. The data set, called the COVID-19 Open Research Data Set, includes more than 29,000 scholarly articles about the virus, and will grow as more are published.
