Coronavirus updates: US reports nearly 300,000 new cases in all-time high

New Zealand will require all travelers from the United States and the United Kingdom to test negative for COVID-19 before departing for the country.

The new rule, which will come into effect Jan. 15, is in addition to a requirement that was implemented from Dec. 31 for passengers arriving from both nations to be tested within 24 hours of their arrival in New Zealand and to remain isolated until a test result is available. The U.S. and the U.K. are two of the hardest hit countries in the coronavirus pandemic.

The latest measures "are extra precautionary steps which provide another layer of protection for New Zealand from COVID-19," New Zealand's Ministry of Health said in a statement Sunday.

New Zealand, an island nation of 5 million people in the southwestern Pacific Ocean, has reported at least 2,181 confirmed cases of COVID-19 since the start of the pandemic, including 25 deaths, according to the latest data from the health ministry.

The U.S. death toll from the coronavirus pandemic has surpassed 350,000.

The number of people who have died from COVID-19 in the United States was 350,186 as of early Sunday morning, according to a real-time count kept by Johns Hopkins University.

The country has by far the highest death toll from the disease.

The U.S. set another record for most daily cases, despite some states not even reporting totals due to the New Year's holiday.

There were a record 275,897 cases reported Saturday, even though seven states did not relay any data, according to The COVID Tracking Project.

"Some states are reporting normally, some are reporting multiple days of data, and almost all are dealing with at least some holiday backlogs," the project said.

The seven-day average for hospitalizations stands at a record 123,689 despite incomplete data. There were 2,367 deaths reported on Saturday, too.

Officials expect numbers to spike after the holidays as people return home from gatherings with family and friends.

Legendary talk show host Larry King, 87, has been hospitalized in Los Angeles for COVID-19, a source close to the King family confirms to ABC News.

"Larry has fought so many health issues in the last few years and he is fighting this one hard too, he's a champ," the source close to the family told ABC News.

King, who hosted "Larry King Live" on CNN for 25 years, revealed in 2017 he had been treated for lung cancer. He suffered a major heart attack in 1987 and the tumor was discovered during an annual checkup. He had an angioplasty in April 2019 and suffered a stroke in 2019 as well.

The host went through unbearable tragedy last year when two of his children died less than a month apart. His son, Andy, died of a heart attack in July and his daughter, Chaia, died of lung cancer in August.

King is hospitalized at Cedars-Sinai Medical Center in LA. The news was first reported by ShowBiz411.
