Gorillas at San Diego Zoo Safari Park test positive for Covid-19
The San Diego Zoo Safari Park said Monday that some of its gorillas have tested positive for Covid-19.
Two of the gorillas started coughing last Wednesday, so the zoo began testing fecal samples for the coronavirus, the zoo said in a statement. The preliminary tests detected the coronavirus on Friday, and the positive results were confirmed Monday.
“Aside from some congestion and coughing, the gorillas are doing well,” said Lisa Peterson, executive director, San Diego Zoo Safari Park. “The troop remains quarantined together and are eating and drinking. We are hopeful for a full recovery.”
The zoo said it suspected the gorillas got the infections from an asymptomatic staff member, despite following all recommended precautions — including COVID-19 safety protocols from the CDC and San Diego County Public Health, as well as wearing PPE when they were near the gorillas.
Biden receives second dose of Covid-19 vaccine
President-elect Joe Biden on Monday received his second dose of the Covid-19 vaccine, setting an example as part of his incoming administration's message that eligible Americans should get vaccinated as soon as possible.
"My No. 1 priority is getting vaccine into peoples' arms like we just did today as rapidly as we can," Biden told reporters after getting a shot in Newark, Delaware.
Biden, who at 78 will become the oldest president in the nation's history, received his first dose of the Pfizer-BioNTech vaccine last month live on national television.
Biden has vowed to meet a goal of 100 million vaccine doses administered in his first 100 days in office, a target that has grown increasingly complicated as states struggle to adequately distribute their doses and gain public trust in a fast enough clip.
"It's not gonna be easy," he added, "but we can get it done."
New York City police start receiving Covid vaccine
Two NBA games called off due safety protocols
Two more NBA games were postponed and will have to be made up later, due to potential coronavirus outbreaks, officials said Monday.
A contest between the visiting New Orleans Pelicans and Dallas Mavericks will not be played as scheduled on Monday night while Tuesday night's matchup between the Boston Celtics and host Chicago Bulls was also postponed, the league announced.
Democratic rep. says she contracted Covid-19 while sheltering in place during riot
Rep. Bonnie Watson Coleman, D-N.J., received a positive rapid Covid-19 test Monday after what she said might have been her exposure to the coronavirus while sheltering in place with lawmakers who did not wear masks during the rioting at the Capitol last Wednesday, her office announced.
“I received a positive test result for COVID-19, and am home resting at this time. While I am experiencing mild, cold-like symptoms, I remain in good spirits and will continue to work on behalf of my constituents," Watson Coleman said in a statement.
The congresswoman is isolating and waiting for the results of a PCR test, which is known to be more accurate than rapid tests.
This comes a day after the Capitol physician warned members and congressional staff that they could have have been exposed to someone infected with the virus when they were sheltering in place. A video circulated last week that showed a House Democrat in a secure room offering face masks to a group of her fellow Republicans, who were seen turning them down.
Teachers, police, transit workers eligible for vaccines in N.Y.
New York on Monday authorized doses of the Covid-19 vaccine to a new category of people, including teachers, police officers and firefighters, as the state edges closer to meeting its weekly vaccination goal.
Gov. Andrew Cuomo said that New York had administered 259,000 doses of the vaccine last week — the first time since the start of the vaccine roll out in December that the number of doses given out surpassed 200,000. The state receives about 300,000 vaccine doses each week.
But the Centers for Disease Control and Prevention says that New York has only administered about 36 percent of the 1.2 million doses it has gotten, highlighting an ongoing struggle between the state and local municipalities to agree on distribution plans.
Also eligible for the vaccine this week are public transit and safety workers and people over 75. Appointments are required. The ability for more people to get shots comes as New York City expands vaccination sites in Brooklyn and the Bronx to operate 24 hours, seven days a week, with other boroughs to follow suit.
George H.W. Bush's sister, Nancy Ellis, dies of Covid complications at 94
The George and Barbara Bush Foundation shared the news in a tweet on Sunday afternoon, writing, "We are sad to share that President Bush’s beloved sister, Nancy Bush Ellis, has passed away. Our condolences and prayers are with the Ellis and Bush families as we remember a remarkable woman who brought joy and light to the world."
Ellis was hospitalized on Dec. 30 with a fever and tested positive for the coronavirus, her family said in a statement. Her symptoms resolved in a few days, but her health was already failing, they said.
Biden adviser tamps down expectation of 100M shots in 100 days
A member of President-Elect Joe Biden's coronavirus advisory board suggested Monday that his vow to get 100 million Covid-19 vaccinations administered within his first 100 days in office is not a given.
Biden "is very committed to trying to make that work," Dr. Celine Gounder said on CNN of the aggressive pace. "That said, we really do have our work cut out for us."
"I think there is still a glimmer of hope that we may still be able to accomplish this," she added. "But it's really going to require everybody working together, not squabbling over partisan issues to get the job done."
Gounder said Congress must step up with the new administration and ensure funding and commitment to distributing the vaccines as the number of Covid-19 cases continues to climb across the U.S. daily.
Millions of doses have gone unused as states and local health agencies struggle to administer the vaccine because of crashing computer systems and long lines. While the Centers for Disease Control and Prevention has said 22 million doses were distributed so far, there have been fewer than 7 million shots actually administered.
U.S. tallies 2,100 deaths, 214,000 cases
