Puerto Rico's COVID-19 positivity rate spiked to 33% on Monday, according to the island’s health department COVID dashboard.

This is a 16-fold jump from the 2% positivity rate reported just two weeks ago, which was a record low.

Scientist Mónica Feliú-Mójer from Ciencia PR, an organization that focuses on scientific education in Puerto Rico, said the rapid increase is due to many factors, including people's behavior.

She said people gathering over the holidays, while a highly transmissible variant continued to spread, led to the spike in the positivity rate.

“The holidays are culturally very, very important and everyone thought this would be a different Christmas. People were eager to get together,” Feliú-Mójer told ABC News.

South Korea on Monday reported the deaths of two patients in their 90s who tested positive for omicron.

Both were receiving treatment in Gwangju, about 200 miles south of Seoul, the semi-official Yonhap News Agency said.

South Korean health officials reported 111 new omicron cases on Monday, bringing its total to 1,318 omicron cases.

About 83% of South Korea's population has been fully vaccinated, according to the Korea Disease Control and Prevention Agency. About 36% received a booster.

Israel's Ministry of Health approved a fourth dose of COVID-19 vaccine for health care workers and people over 60 years old, Prime Minister Naftali Bennett said.

"Israel will once again be pioneering the global vaccination effort," Bennett said at a press conference in Jerusalem. "Omicron is not Delta -- it’s a different ball-game altogether."

Fourth doses will be administered four months after booster shots, Bennett said.

The White House said Wednesday it is confident it can deliver millions of rapid COVID-19 tests to Americans in January.

Last month, the administration announced it was planning to distribute 500 million free at-home rapid tests across the country to combat the surging omicron variant.

However, a website has yet to be launched where people can order the tests and the U.S. is currently producing less than half of the tests needed -- 200 million a month.

During a virtual briefing, Jeff Zients, the White House Coronavirus Response Coordinator, said the government not only has the capacity to deliver 500 million tests, but it also won't dip into the current supply on pharmacy shelves.

"With all the companies that now have been authorized, there’s the capacity for the U.S. government to purchase the 500 million now and not disrupt, or in any way cannibalize, the tests that are on pharmacy shelves and on websites and used and other settings," he said.
