Omicron Continues Worldwide Spread

The newest variant was discovered just over a week ago by scientists in South Africa and Botswana, and it's now been found in multiple countries.

Mexico's Health Department announced Friday it had detected the country's first case of the omicron variant of the coronavirus.

The first case was detected in a South African citizen who entered Mexico on November 21, and began to feel ill on November 27.

They were being treated in isolation at a private hospital in Mexico City, President Andrés Manuel López Obrador said.
