Seattle firefighters wearing masks, gowns, and gloves to protect against the transmission of the new coronavirus, walk and stand near their engine after responding to a medical call in Seattle Tuesday, March 24, 2020. First responders across the country are now responding to even routine calls wearing personal protective equipment to try and slow the outbreak of the new coronavirus, which 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.
