As of Tuesday evening, newly reported cases of the novel coronavirus pushed the region’s known total to 162 — 67 in Virginia, 63 in Maryland and 32 in the District. Here are some of the most significant and recent developments as the region responds to the pandemic of the coronavirus that causes the disease covid-19:

• Virginia Gov. Ralph Northam (D) issued an order to let local governments prohibit more than 10 people in restaurants, fitness centers and theaters. He had previously refrained from issuing mandatory limits or closures, such as those in place in the District and Maryland.

• Maryland Gov. Larry Hogan (R) postponed the state’s April 28 primary to June 2, but he will allow mail-in only ballots for a special election to succeed the late Elijah E. Cummings. Hogan also announced Maryland is shutting down vehicle emissions inspection sites and turning them into drive-through coronavirus testing centers across the state.

• Maryland added 22 confirmed cases of the coronavirus — its largest per-day increase. Virginia added 15 cases, while results from 48 tests are pending. The District announced 9 new cases, which is also its largest increase in a single day.

• Metro is further reducing service starting Wednesday as the transit agency said it seeks to further protect passengers and employees. Trains will run every 15 minutes.
