New coronavirus testing sites continue to open across the region, as government leaders say testing and tracking people who have been exposed is key to controlling the spread of the virus.

After initial shortages of tests and supplies, local and state leaders increasingly say they have plenty of tests available. Some locations are no longer requiring a doctor’s note or even an appointment. Others are offering the tests free.

There are 17 testing sites set up at select CVS pharmacies in Maryland. CVS is setting up nearly 350 sites in 14 states to test for the coronavirus.

Last week, Gov. Larry Hogan (R) announced that people who have been exposed to the coronavirus but are not showing symptoms would be able to get tested at several state-run testing sites starting May 21. No appointment or doctor’s referral is needed. He also authorized store pharmacies to purchase and administer tests.

Hogan has come under pressure recently from local leaders who say more people need to be tested before their regions can begin to reopen. Last week, the governor announced the state will provide universal testing at prisons and juvenile detention facilities, in addition to testing at the 227 nursing homes in the state.

D.C. Mayor Muriel E. Bowser (D) has set up two testing sites in the city and is especially encouraging people who have symptoms, are front-line workers, live in institutional settings or are 65 or older to get tested.

A drive-through testing site in Loudoun County administered 1,700 tests on May 20. The tests were free and conducted by a private testing lab through a contract with the Virginia Department of Health. Some people had to wait two to three hours in a long line of cars for a test, according to David Goodfriend, a physician and director of the county health department.

“In terms of the volume it very much exceeded our expectations,” he said in a phone interview.

Here are details of places you can get tested in the region:
