New record highs set in Illinois, Ohio, New York, New Jersey

New York and New Jersey set record case highs again on Thursday with 38,835 and 18,660 new daily cases respectively.

The new high came as New York saw a record high for testing as people check their status before seeing relatives for the holidays.

Illinois and Ohio also shattered pandemic case records Thursday with 18,942 and 15,989 new cases respectively, according to ABC Chicago station WLS and ABC Cincinnati affiliate WCPO.

Until this week, Ohio hadn't seen over 12,000 daily cases since January, WCPO reported.

In response to the case surge in Cook County, Illinois, which encompasses Chicago, customers must show proof of vaccine inside restaurants, bars, gyms and entertainment venues beginning Jan. 3.

Major nurses' union condemns new CDC health care quarantine guidance

Not long after the U.S. Centers for Disease Control and Prevention updated its quarantine guidance for health care workers, the largest union of registered nurses fired back at the agency calling the shorter isolation period "dangerous."

National Nurses United (NNU) contended the update, which allows workers with COVID-19 to return to work seven days with a negative test if they are asymptomatic, would result in more transmission of the virus and focuses on profit margins, rather than stopping the spread.

"Sending frontline nurses and other health care workers to work while infected would be dangerous," NNU President Zenei Triunfo-Cortez said in a statement.

CDC updates quarantine guidance for health care workers

The U.S. Centers for Disease Control and Prevention updated its guidance to health care workers who need to quarantine.

The updated rules come as health care facilities around the country are reporting staff shortages brought on by the rise in omicron cases.

Under the new guidance, the CDC said health care workers with COVID-19 and who are asymptomatic can return to work after seven days with a negative test.

"Isolation time can be cut further if there are staffing shortages," the agency said in its updated guidance.

Health care workers who received both vaccine doses and a booster don't need to quarantine following high-risk exposures, the CDC said.
