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.

About half of COVID-19 patients hospitalized in New York City were originally admitted for other reasons, Gov. Kathy Hochul said.

Across the state, 42% of COVID-19 patients entered hospitals for reasons unrelated to the virus, such as a car accident, and only learned they were positive during their stays, Hochul said during a press conference Friday.

This is the first time that New York has differentiated between patients who go to hospitals to get care for COVID-19 and those who seek out care for other issues but test positive upon arrival.

Hochul also asked New Yorkers who have mild symptoms to not got to emergency rooms to get tested or treated because many hospitals are currently understaffed.

"If you're an adult with very minor symptoms, you can handle a runny nose. You can handle the throats being a little sore, a little bit of a cough. Just treat as if you would the flu, all the protocols," she said. "But please don't overburden our emergency rooms."

Hochul added that nearly 20% of all emergency rooms in the state are made up of people who are there only to get tested for COVID-19.
