In this Wednesday, April 8, 2020, photograph, Ben Prater shows where one of the social distancing markers is placed on the floor and the traffic flow that he encourages at his marijuana dispensary as a statewide stay-at-home order remains in effect in an effort to reduce the spread of the new coronavirus in Denver. The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.
