WATCH: White House COVID-19 task force gives update on pandemic

The White House COVID-19 task force gave an update Monday on the ongoing novel coronavirus pandemic, which has now killed more than 534,000 Americans.

Watch the briefing in the video player above.

The Biden administration is pleading with Americans to follow public health guidance on mask-wearing and refraining from nonessential travel as the coronavirus continues to infect more than 50,000 Americans each day.

Centers for Disease Control and Prevention director Dr. Rachelle Walensky says she is alarmed by escalating rates of travel, including around college spring break. Walensky pointed to the Transportation Security Administration reporting the heaviest travel date on Friday since the pandemic began, as well as images of maskless partygoers in beach towns as risks for another spike in virus cases.

Walensky notes cases of the virus have been on a slight decline over the last several weeks, but remain at elevated levels.
