Hospitals and clinics in cities across the U.S. have recently established drive-through testing for COVID-19. It's the strategy that enabled countries like South Korea and Japan to test as many as one out of every 142 people for SARS-CoV-2, the virus that causes the infectious disease, thus helping to track and slow the virus' spread.

But a tiny clinic in central Pennsylvania, tucked in amongst neat farmsteads covering the anthracite hills, is setting up drive-through testing that's meant to accommodate a horse and buggy as well as cars. The Central Pennsylvania Clinic caters to the local Amish and Mennonite communities, and its founder, D. Holmes Morton, wants to ensure that rapid COVID-19 testing isn't limited to those with motorized vehicles.
