Coronavirus updates: 23-year-old college student dies from COVID-19

More than 1 million U.S. children have tested positive for COVID-19 since the start of the pandemic, according to a report published Monday by the American Academy of Pediatrics and the Children’s Hospital Association.

Last week, nearly 112,000 children were diagnosed, marking the largest weekly increase since the U.S. outbreak began.

Because states differ in how they report on age groups, this report includes infants through teens. In total, infections among children represent 11.5% of overall U.S. cases. Since COVID-19 symptoms in children tend to be milder than those in adults, experts believe many cases go undiagnosed and that current figures are most likely an undercount.

Philadelphia officials announced sweeping COVID-19 restrictions Monday that will last through the end of the year.

Colleges, universities and high schools are required to switch to online learning, and churches have been asked to hold online services. All employees able to work remotely should do so.

Additionally, outdoor gatherings will be limited to 10% occupancy, and food and beverages are not allowed to be served.

"I know these restrictions are tough," Dr. Thomas Farley, Philadelphia's health commissioner, said Monday. "People are going to be put out of work, and some businesses may go under," Farley added. "We also know that the consequences to health of not doing it are really bad."

"If we do this right, our businesses will recover faster because the epidemic wave will subside sooner."

The new rules go into effect on Friday.

The U.S. Labor Department's Occupational Safety and Health Administration has issued more than $2.8 million in fines for failing to properly protect employees from COVID-19.

The violations compiled by OSHA include failure to implement plans to protect workers from respiratory viruses; failure to provide workers with PPE or train them to wear it properly; failure to report illness or death; and failure to to provide a safe workplace.

Since the pandemic began, OSHA has issued 204 citations and $2,856,533 in penalties, many in nursing homes and health care facilities.

Nearly 70,000 people are currently hospitalized due to complications with COVID-19 as intensive care units around the country run out of space and supplies.

The number of hospitalization shows no signs of slowing down after the seven-day average of patients currently hospitalized with COVID-19 increased by 23%, according to an ABC News analysis of the trends across 50 states, Guam, Puerto Rico and Washington, D.C., using data from the COVID Tracking Project.

The virus also continues to disproportionally impact Americans of color. According to data from the Centers for Disease Control and Prevention for the week ending on Nov. 7, hospitalization rates for Hispanic or Latino individuals are 4.2 times higher than that of non-Hispanic White individuals. American Indian or Alaska Native individuals have been hospitalized at 4.1 times the rate of non-Hispanic White individuals, and Black individuals have been hospitalized at 3.9 times the rate of non-Hispanic White individuals.

The U.S. is now averaging almost 145,000 new cases a day -- nearly four times the daily average from just two months ago. In the last seven days, the average number of new COVID-19 cases has increased by 35%.

The 1 million Americans diagnosed with the virus in the last seven days equates to 101 every minute.
