In its latest weekly assessment of the COVID-19 pandemic, the U.N. health agency said there were 5.3 million new cases and more than 14,000 deaths reported last week. WHO said the number of new infections declined in every world region except the Western Pacific.

Monday marks the first day of the 2022-23 school year, as some 300,000-plus students head back to class on one of the earliest start dates in recent memory.

Chicago Department of Public Health officials continue to recommend that residents wear masks indoors and on public transportation to reduce their risk of contracting COVID-19 and ensure they are up to date with their COVID-19 vaccines.

The U.N. health agency said there were more than 14,000 COVID-19 deaths in the last week and nearly 7 million new infections. The number of new deaths rose by 19% in the Middle East, while dropping by more than 70% in Africa, 15% in Europe and 10% in the Americas.

“Back to the Oval,” President Joe Biden tweeted after the White House released the latest daily update from his doctor confirming that he was clear to end the isolation period that is required after someone tests positive for the coronavirus. Biden, 79, tested positive last week.

White House Press Secretary Karine Jean-Pierre said that Biden was experiencing “mild symptoms” and has begun taking Paxlovid, an antiviral drug designed to reduce the severity of the disease.

Chicago Department of Public Health officials recommend that residents wear masks indoors and on public transportation to reduce their risk of contracting COVID-19 and ensure they are up to date with their COVID-19 vaccines.

The threat of COVID-19 eased across Chicago and Cook County Thursday, as federal officials lowered the warning level to “medium” after two weeks at “high,” according to Centers for Disease Control data. However, Chicago Department of Public Health officials continue to recommend that residents wear masks indoors and on public transportation. 

One week ago, federal officials lowered the risk warning level to high for Cook County. But even as confirmed cases of COVID-19 continued to drop, hospitalizations rose just enough across Cook County to trigger an increase in the warning level by federal officials.

COVID-19 posed a high risk in Chicago and Cook County for 21 days, but neither state, county nor city officials imposed new restrictions designed to prevent the spread of COVID-19. Chicagoans should consider the CDC’s medium level of risk warning as “a yellow light of caution,” Dr. Allison Arwady has said.

That stance marks a sharp reversal of the U.N. health agency’s initial assessment of the pandemic’s origins. WHO concluded last year that it was “extremely unlikely” COVID-19 might have spilled into humans from a lab.

Chicago officials will not immediately reimpose an indoor mask mandate because the city’s hospitals are not being strained by the number of people seriously sick with COVID-19.

Since May 5, federal health officials have warned all residents of Cook County that they face a “medium” risk of contracting COVID-19. Since then, Chicago health officials have “strongly” urged Chicagoans to wear a mask when they are indoors, particularly in a crowded setting where they are unaware of the vaccination status of those around them.

Experts say testing has dropped by 70 to 90% worldwide from the first to the second quarter of this year — the opposite of what they say should be happening with new omicron variants on the rise in places such as the United States and South Africa.

Chicago, Cook County and several surrounding counties have all recently been designated as being at “medium risk” of their residents contracting COVID-19. 

Residents of seven northeast Illinois counties — McHenry, Lake, Cook, Kendall, DuPage, Will and Grundy — face a medium level of COVID-19 risk, according to the CDC. Dr. Allison Arwady, the commissioner of the Chicago Department of Public Health, said Chicagoans should consider the CDC’s medium level of risk warning as “a yellow light of caution.”
