Coronavirus updates: CDC forecasts up to 226K US deaths by mid-October

The Pac-12 will resume its football and basketball seasons in November, the conference announced on Thursday.

A seven-game, conference-only football season will begin on Nov. 6, with the Pac-12 Championship game scheduled for Dec. 18. Pac-12 universities with the necessary public health approvals can start practice immediately, the conference said.

The University of Colorado halted football practices for two weeks on Thursday after Boulder said it was banning gatherings of 18- to 22-year-olds.

The season for men's and women's basketball will start on Nov. 25 -- the same as the NCAA's official start date for those sports. 

Other winter sports can begin in line with their respective NCAA seasons, the conference said.

In August, the CEO group had voted to postpone all sports, including football and basketball, through at least the end of the year.

Thursday's announcement was based on updated Pac-12 recommendations "that take into account material changes to testing capabilities, the prevalence of COVID-19 and cardiac issues, along with updated state and local health official guidance," the conference said in a release.

Student-athletes will take daily antigen tests, as well as at least one weekly PCR test, officials said. 

No fans will be allowed to attend competitions taking place on Pac-12 campuses. The conference will revisit that decision in January, officials said.

There were 16,096 new COVID-19 cases reported in France on Thursday, marking the highest one-day rise since the beginning of the outbreak, French health authorities said.

The nation now has over 497,000 people diagnosed with COVID-19.

The death toll increased by 52 on Thursday, bringing the fatality total to 31,511.

France reported 4,258 new hospitalizations in the last week, including 718 patients in intensive care.

France on Wednesday announced new restrictions to combat the rise in cases.

Starting Monday in Paris and seven other major cities, outdoor gatherings will be limited to 10 people. Bars must shut their doors at 10 p.m., gyms will be closed and sporting events will be limited to 1,000 spectators.

Marseille, Aix-en-Provence and Guadeloupe are enacting stricter rules; starting Monday all bars and restaurants will be closed.

In Boulder, Colorado, people ages 18 to 22 will soon be banned from all gatherings, whether indoors, outdoors, or with people outside that age range, the Boulder County Public Health Department announced.

This comes after nearly three weeks of cases rising in Boulder County, "with the vast majority" connected to 18 to 22 year olds, "particularly those attending the University of Colorado Boulder," the department said.

"While there has been little evidence of spread of the virus beyond the 18-22 age group, the continued increase in new cases in the city of Boulder prompted the Public Health Order to help prevent the spread to other community members," the department said.

The health department also calls out 36 addresses where the department claims residents "repeatedly engaged in activities that violate public health orders." Those residents must stay in their homes for two weeks, only leaving for essential services, according to the Health Department.

The order will last for two weeks, beginning at 4 p.m. local time on Thursday.

Residents in the 18 to 22 age group are exempt for exercising outside alone, studying outside alone and going to work if they don’t live in one of the homes with stay-at-home requirements.

Young adults can interact with relatives they live with, and those in high school can participate in school activities, the department added.

"While there has been little evidence of spread of the virus beyond the 18-22 age group, the continued increase in new cases in the city of Boulder prompted the Public Health Order to help prevent the spread to other community members," the department said.
