White House to lift travel restrictions on southern African countries

The travel restrictions on eight southern African countries, put in place by the White House when omicron emerged, will be lifted on Dec. 31, according to a senior administration official.

This decision was recommended by the CDC for two reasons, the official said: vaccines and boosters have been determined to help prevent severe disease from omicron; and omicron is already prevalent in the U.S. and around the world so travel from those eight countries won't have a major impact on U.S. cases.

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.
