New coronavirus cases in D.C. — which had been on a sharp decline in June — are ticking upward, fueled by stagnant vaccination rates and the rise of the highly contagious delta variant.

Here are answers to some common questions.

Are coronavirus cases going down in D.C.?

No. You can follow the trends on The Washington Post’s tracker.

How many people in D.C. have been vaccinated so far?

The Washington Post’s tracker has information on the number of people in the District who have been vaccinated.

I haven’t gotten vaccinated yet — do I still need an appointment?

No. You can choose to make an appointment at a pharmacy or clinic if you’re most comfortable there, but you can also go to a city-sponsored walk-up clinic. Visit this city website to see the latest list of walk-up locations across the city.

Are children and teens able to get vaccinated yet?

Yes, children and teens age 12 are eligible to get vaccinated in D.C. Check here for vaccination sites.

Are there any pandemic restrictions in D.C.?

Citing rising case rates, Mayor Muriel E. Bowser (D) reinstated an indoor mask mandate for vaccinated and unvaccinated people over the age of 2. She has not reimposed social distancing or capacity restrictions for businesses.

Are there any vaccination mandates in D.C.?

Bowser imposed a vaccination requirement on city employees on Aug. 10. All city employees and contractors now will be required to be vaccinated or undergo weekly testing for the coronavirus, with vaccination required for new employees. The administration is hammering out a policy with labor unions representing city workers, including the Washington Teachers Union, over how noncompliant employees might be disciplined, among other issues.

City officials announced on Aug. 16 that all health-care employees in D.C. must get at least the first dose of the coronavirus vaccine or begin regular testing by Sept. 30. D.C. Health Director LaQuandra Nesbitt said the requirement applies to licensed and unlicensed health professionals and EMS providers working in the city. For now, workers can opt out in favor of regular testing. Once one of the vaccines gets full federal approval, however, workers can opt out only if they have a religious or medical exemption.

D.C. Attorney General Karl A. Racine (D), an independent elected official, has mandated employees of his office show proof of vaccination by Sept. 13 or get tested weekly.

Is the city offering incentives for me to get the vaccine?

The city offered $51 gift cards to those who got their shots at selection locations, along with drawings for cars, Metro cards, and grocery store credits. Special drawings for teenagers are also being held.

Will I need a booster shot — and if so, how can I get one?

The Biden administration will begin offering coronavirus booster shots the week of Sept. 20, after concluding that a third shot is needed to fight off waning immunity.

Officials said the decision was driven by data showing a decline over time in the vaccines’ ability to protect against less-serious disease; evidence that boosters work and that more protection may be needed against the dominant delta variant; and a desire to stave off any potential decrease in the shots’ effectiveness against severe illness.

The officials said the plan would be implemented only if the Food and Drug Administration approved boosters and the Centers for Disease Control and Prevention advisers recommended them.

The federal government also will direct all nursing homes to require vaccination for staffers or face loss of Medicare and Medicaid funds — an escalation by the Biden administration as it tries to get more Americans vaccinated amid the delta variant surge.

People who are immunocompromised — such as those undergoing cancer treatment or those who have received organ transplants — are able to get third doses 28 days after their second dose.
