Baltimore will shut down indoor and outdoor dining beginning Friday, said Mayor Brandon Scott, who was sworn in on Tuesday.

Restaurants can offer takeout and delivery.

Scott’s order also sets a 25% capacity limit at retail stores, religious institutions, gyms and malls.

The new rules come as Maryland reported a record number of hospitalizations during the pandemic -- 1,715 patients -- surpassing the previous peak in April.

President Donald Trump's personal lawyer, Rudy Giuliani, told WABC Radio that he'll be discharged from the hospital Wednesday afternoon following his COVID-19 diagnoses.

“I feel just about 100% right now," he said.

Giuliani said he will isolate for a few more days “because the way they calculate it, I probably got it [the virus] about seven, eight days ago.”

Seven days ago, Giuliani was in Michigan, testifying at the state's House Oversight Committee hearing for suspicion of voter fraud. The next day, he appeared at a hearing at the Georgia Senate Judiciary Committee to contest that state's results.

Dr. Anthony Fauci stressed Wednesday that the speed of vaccine development “was not compromising safety, nor was it compromising scientific integrity.”

"The speed is really a reflection of the extraordinary scientific advances that have been made that allowed us to do things in weeks to months that normally would have taken several years," Fauci explained at the Johns Hopkins Bloomberg School of Public Health Summit. "The process that went into deciding the safety and efficacy was both independent and transparent."

"We've got to be doing a lot of community engagement and community outreach to get people to understand," Fauci said.

An 83-year-old passenger on board Royal Caribbean International’s Quantum of the Seas tested positive for COVID-19 on Wednesday, Singapore's Ministry of Health said in a statement.

The passenger had reported to the ship medical center with symptoms and was tested with PCR equipment on board. The 83-year-old was immediately isolated after getting the results.

Close contacts of the individual have tested negative and have been quarantined.

Singapore's National Public Health Laboratory will re-test that sample and a second sample will be taken to verify the results.

An epidemiological investigation has been initiated and contact tracing is in progress, the Ministry of Health said. All passengers will undergo mandatory COVID-19 testing before they are allowed to leave the terminal at Marina Bay Cruise Centre.

The ship will go through a "deep cleaning and disinfection," the cruise line said in a statement.

"The health and safety of our guests and crew are of utmost importance to us, and we have made the decision to cancel the 4-night cruise departing tomorrow, December 10," Royal Caribbean said.

South African Health Minister Zweli Mkhize has called on final-year students who attended end-of-year parties to immediately self-quarantine for 10 days to prevent spreading the novel coronavirus.

Mkhize made the plea to students and parents on Sunday, after numerous people who recently attended "Rage" parties in Ballito and Jeffrey's Bay tested positive for COVID-19. The events are hosted every year in South Africa as thousands of students celebrate the end of matriculation.

"We confirm that we have now identified a number of COVID-19 confirmed cases arising from these super-spreader events," Mkhize said in a statement. "This therefore means that if you attended any of these Rage events, you are now regarded as a contact."

In addition to quarantining, Mkhize also urged attendees to get tested as soon as possible.

South Africa has the highest tally of COVID-19 infections in all of Africa, with more than 814,000 confirmed cases including over 22,000 deaths.
