More than 100,000 Americans are hospitalized with COVID-19

More than 100,000 Americans are currently hospitalized with COVID-19, according to data from the U.S. Department of Health and Human Services.

A total of 103,329 people are receiving medical care, which is an increase of 130% from the number recorded two months ago.

Of those patients, more than 17% -- about 18,000 -- are in intensive care units.

The newly updated figure is just shy of the hospitalization peak seen during the summer wave fueled by the delta variant, when 104,000 Americans were hospitalized with COVID in early September.

FDA authorizes Pfizer's booster shot for 12- to-15-year-olds

The U.S. Food and Drug Administration authorized booster shots of Pfizer-BioNTech's COVID-19 vaccine in children between ages 12 and 15 on Monday.

Booster shots have been touted as a key tool in fighting the surge in COVID cases linked to the omicron variant, which has shown an ability to -- at least partially -- evade protection offered by two doses.

In addition, the agency authorized COVID booster shots for children aged five to 11 who are immunocompromised.

Puerto Rico's COVID positivity rate jumps from 2% to 33%

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.
