Coronavirus updates: Los Angeles to prohibit gatherings, close playgrounds

Los Angeles County Director of Public Health Barbara Ferrer announced the county will shut down in-person restaurant dining starting Wednesday as cases continue to rise.

The county recorded 6,124 new cases and eight new deaths Monday, according to the local Health Department. There are 1,473 patients currently hospitalized with COVID-19 in L.A. County, the Health Department said.

Eateries and bars will be able to offer take-out options, according to Ferrer. The order will be in effect for at least three weeks, she said.

The Los Angeles County Board will meet Tuesday to discuss further shutdown measures. If the five-day case average is 4,500 or higher, a more restrictive stay-at-home order will be issued for three weeks.

"The problem is, we have such a high rate of transmission and so many people are infected that it will take a lot to get us back down," Ferrer said.

Maryland Gov. Larry Hogan announced his state will launch an education campaign and additional enforcement action this week, as the state sees a surge in COVID-19 cases.

Maryland has seen 19 straight days with over 1,000 new daily cases recorded, Hogan said. The positivity rate is 6.8%, hospitalizations have increased by 80% in the last two weeks, and  29 hospitals are at 90% capacity, according to the governor.

Federal and state officials have announced they will enforce compliance rules over Thanksgiving. A wireless alert will be send out on Wednesday that reminds the public about the pandemic and the state's enforcement.

"Following the public health directives is the only way we will be able to stop this virus, keep Maryland open for business, and keep hospitals from overflowing," Hogan said in a statement.

The Buffalo Bills announced that one of their players would be out for the rest of the season due to a heart issue brought on by the coronavirus.

The team tweeted that a cardiologist discovered tight end Tommy Sweeney had myocarditis, an inflammation of the heart, which was connected to COVID-19.

Sweeney was placed on the team's reserve/COVID-19 on Oct. 24.

The U.S. Department of Health and Human Services announced they have begun to ship the the first batch of Regeneron’s antibody treatment to hospitals across the country.

President Donald Trump was treated with Regeneron when he was hospitalized with the coronavirus in the beginning of October.

The treatment is authorized for use for patients 12 and older with mild to moderate COVID-19 but are at higher risk of getting very sick. Health care providers will decide who gets access to the drug based on need, according to HHS officials.

The federal government provided around 30,000 doses to the hospitals so far and will ship tens of thousands more in the weeks to come, according to officials.
