Amazon is teaming up with researchers funded by Microsoft co-founder Bill Gates to pick up and deliver coronavirus test kits.
The Gates Foundation-backed Seattle Coronavirus Assessment Network (SCAN) is learning how the infection spreads.
It involves collecting nasal swabs to track the virus among residents of Seattle's King County in Washington.
Amazon Care, the retail giant's employee medical care arm, is now helping with deliveries of the kits.
King County is one of the places hardest hit by the outbreak in the US.
