There were 209,988 new cases of COVID-19 confirmed in the United States on Monday, according to a real-time count kept by Johns Hopkins University, although that data likely includes a backlog from the weekend.

This is the third time this month that the U.S. has reported more than 200,000 newly confirmed infections in a single day.

Many states are no longer reporting COVID-19 data daily. Single-day case totals, particularly early on in the week, may be skewed as a result of a backlog release of data.

Bangladesh has launched a COVID-19 vaccination program for Rohingya refugees housed in one of the world's largest and most densely populated camps in Cox's Bazar, according to a press release from the World Health Organization.

The campaign, led by the Bangladeshi government with technical support from the WHO and other partners, is initially targeting nearly 48,000 Rohingya refugees who are 55 and older. It's part of Bangladesh's national deployment and vaccination plan to ensure equity and fair allocation of vaccines across the country.

"Bangladesh is demonstrating what WHO has been advocating for -- equitable access to vaccines," Dr. Poonam Khetrapal Singh, regional director of the WHO South-East Asia Region, said in a statement Monday. "Inclusion is key to protecting vulnerable populations like the refugees, for safeguarding their health and that of their host communities and societies."

More than 1 million Rohingya -- a stateless ethnic group who predominantly practice Islam -- are sheltering in crowded camps in Bangladesh after fleeing persecution in Buddhist-majority Myanmar.

The Biden administration could soon be urging Americans to get a booster shot eight months after completing their original vaccination, a source familiar with the discussions told ABC News Monday.

Federal health officials and experts are currently coalescing around the idea that all Americans should receive a booster, the source said. Those booster shots could be rolled out as soon as mid to late September -- pending Food and Drug Administration authorization.

The announcement, first reported by The New York Times and The Washington Post, could come as soon as this week.

The new timeline for the booster shots in a significant shift for the administration, which previously had been non-comital on when boosters for the majority of Americans would be needed.

The city of El Paso has filed a lawsuit challenging Texas Gov. Greg Abbott’s ban on mask mandates in the state to allow for local protective measures to be ordered in the county.

Starting Wednesday at 12:01 a.m., a local health authority order will mandate that all individuals over the age of 2 wear some form of face covering while in public indoor spaces.

The parents of children under the age of 10 will be responsible for appropriately masking their children while outside their home, city officials said.

The order comes after El Paso City-County Health Authority Dr. Hector Ocaranza recommended masks at all indoor facilities in the county.

A face covering is not required on those who are eating or drinking or anyone who has trouble breathing, has a medical condition or disability that prevents wearing a face covering.

U.S. Surgeon General Vivek Murthy announced at Wednesday's White House briefing, "Having reviewed the most current data, it is now our clinical judgment that the time to lay out a plan for COVID-19 boosters is now."

Murthy said protection against mild disease has decreased, likely a combination of waning vaccine protection over time and the strength of the delta variant, and that the administration is "concerned" that protection could continue to erode.

"Even though this new data affirms that vaccine protection remains high against the worst outcomes of COVID, we are concerned that this pattern of decline we're seeing will continue in the months ahead, which could lead to reduced protection against severe disease, hospitalization and death," Murthy said.

"That is why, today, we are announcing our plan to stay ahead of this virus by being prepared to offer COVID-19 booster shots to fully vaccinated adults 18 years and older," Murthy said. "They would be eligible for their booster shot eight months after receiving their second dose of the Pfizer or Modern mRNA vaccines."

The boosters are set to begin Sept. 20, but Murthy emphasized that this is pending FDA authorization and also reiterated that does not yet apply to J&J recipients.
