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.

As COVID-19 cases surge pediatricians are experiencing a first: sick children facing both respiratory syncytial virus, or RSV, and COVID-19.

"We've not seen this before -- we have two very highly contagious respiratory viruses circulating at the same time, particularly throughout the South around Texas and neighboring states," Dr. Jim Versalovic, pathologist-in-chief at Texas Children's Hospital, told ABC News Live on Monday.

Infants, young children and older adults are most at-risk for RSV, a respiratory virus that's usually more prevalent in the fall and winter. RSV kills 100 to 500 children under 5 each year, according to the Centers for Disease Control and Prevention.

"It's not surprising now to see children being impacted with both viruses, particularly infants and young children who are most susceptible to respiratory syncytial virus," Versalovic said.

He said in "recent weeks we've had 30% or more of our pediatric ICU beds [filled] with RSV infections," including some children also with COVID-19, which "could "mean more severe respiratory illness."

"We do know how to treat these children with RSV and with COVID. And so, for now we're managing that, but it is certainly a new challenge for us," Versalovic said.
