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.

Florida allowed up to a million COVID-19 rapid test kits to expire last month, according to Florida Division of Emergency Management Director Kevin Guthrie.

Guthrie admitted during a press conference Thursday that the stockpile of unused tests, manufactured by Abbott Laboratories, sat idle in a Florida warehouse amid a lack of demand for them.

"We had between 800,000 and 1 million test kits -- Abbott rapid test kits -- in our warehouse that did expire," Guthrie told reporters. "We tried to give them out prior to that, but there was not a demand for it."

The tests expired between Dec. 26 and Dec. 30, after being granted a three-month extension, according to Guthrie. Meanwhile, the country has been grappling with a winter surge of COVID-19 infections, fueled in part by the highly contagious omicron variant and holiday gatherings, that has sparked an increased demand for tests, leading to shortages and long lines across the nation.

Florida Agriculture Commissioner Nikki Fried, a Democratic candidate for governor, has accused Florida Gov. Ron DeSantis and the Florida Department of Health of stockpiling tests amid hourslong lines at testing sites in some parts of the Sunshine State.
