Secretary of State Anthony Blinken criticized the Chinese government for its lack of transparency in the early stages of the COVID-19 pandemic on Sunday's "Meet the Press," and called for a more thorough investigation into the of the origins of COVID-19.

Why it matters: Investigating the origins of the virus has been hallmarked by geopolitical tensions, and U.S. officials have expressed skepticism about a report assembled by the World Health Organization and China.

The maskless woman who coughed on another customer in a Florida Pier 1 last June was sentenced to 30 days in jail Thursday for second-degree assault, the Washington Post reports.

Why it matters: The incident, which illustrates the polarized tension surrounding mask-wearing, took place in June 2020 when COVID-19 cases were surging. A number of videos showing customers refusing to wear masks in stores went viral at the time.

Working-age and young Latinos face disproportionately high COVID-19 death rates as states move toward reopening. Foreign-born Latinos who work essential or front-line jobs are especially in peril.

The big picture: A foreign-born Latino worker in California is 11.6 times more likely to died from COVID-19 than any other non-Hispanic U.S.-born group, according to a new USC study.

1. Health: Coronavirus cases hold steady at 65,000 per day — CDC declares racism "a serious public health threat" — WHO official: Brazil is dealing with "raging inferno" of a COVID outbreak.
2. Vaccines: America may be close to hitting a vaccine wall — Pfizer asks FDA to expand COVID vaccine authorization to adolescents — CDC says Johnson & Johnson vaccine supply will drop 80% next week.
3. Economy: Treasury says over 156 million stimulus payments sent out since March — More government spending expected as IMF projects 6% global GDP growth.

Iran on Saturday began enforcing tightened COVID restrictions nationwide as the number of coronavirus cases surged.

Driving the news: The country on Friday recorded 22,478 coronavirus cases, its highest single-day total, according to Al Jazeera. Health officials confirmed more than 19,660 cases on Saturday, as the surge in new infections follows last month's Iranian holiday celebrations.

Brazil is facing a "raging inferno of an outbreak," Bruce Aylward, senior adviser to the director general of the World Health Organization, warned Friday as the number of coronavirus cases and deaths across the country soars.

Driving the news: The surge, driven in part by relaxed mitigation measures and a more contagious local variant, has overwhelmed the country's health system. Brazil this week confirmed more than 4,000 COVID-19 deaths in a 24-hour period for the first time since the start of the pandemic.

Pfizer and BioNTech asked the Food and Drug Administration Friday to expand the emergency use authorization of its COVID vaccine to cover adolescents ages 12–15.

Why it matters: The authorization would broaden vaccination efforts and speed up the country's race to herd immunity, a goal that will ultimately require teenagers and children to be vaccinated as well.

Allocations of Johnson & Johnson's coronavirus vaccine will plummet by 80% next week, according to data released by the Centers for Disease and Control Prevention.

Why it matters: J&J's single-dose shot is viewed as key to U.S. efforts to vaccinate enough Americans to reach herd immunity as soon as possible. A spokesperson told the Wall Street Journal that J&J is still aiming to meet its goal of delivering 100 million doses by June.

There are growing signs that parts of the country may be close to meeting demand for the coronavirus vaccine — well before the U.S. has reached herd immunity.

Why it matters: For the last few months, the primary focus of the U.S. has been getting shots to everyone who wants them, as quickly as possible. Soon, that focus will abruptly shift to convincing holdouts to get vaccinated.

Rochelle Walensky, director of the Centers for Disease Control and Prevention, on Thursday declared racism "a serious public health threat."

Driving the news: Walensky highlighted the disproportionate impact of the coronavirus pandemic on communities of color, pointing to case and death counts, as well as economic and social effects.
