Omicron updates: COVID outbreak reported on cruise ship docking in New Orleans

The FDA has expanded its emergency authorization for Eli Lilly's monoclonal treatment for the treatment of mild to moderate COVID-19 to children under 12, including newborns, who have tested positive and are at risk for getting severely ill. This expansion also includes preventative use in young kids who may have been exposed and who are at high risk of getting severely ill. 

This is the first time a monoclonal treatment has been authorized for children under 12.

Three cases of the omicron variant have been detected in Maryland, all among Baltimore area residents, Gov. Larry Hogan said.

One of these people, who is vaccinated, recently traveled to South Africa. The second case is someone in their household who is not vaccinated, Hogan said.

The third case is unrelated; this person, who is vaccinated, has no recent travel, Hogan said.

No one required hospitalization, he said.

Six cases of the omicron variant have been detected in Nebraska, health officials announced.

The first individual was likely exposed during travel to Nigeria, officials said. The individual returned to the U.S. on Nov. 23 and developed symptoms the next day.

The five other people were "likely exposed" through household contact with the first case, health officials said.

Only one of the six individuals was vaccinated, officials noted, and none have required hospitalization.
