An advisory panel of the World Health Organization classified on Nov. 27, 2021, a worrying new COVID-19 variant first detected in South Africa as a highly transmissible virus of concern, naming it "Omicron" under its Greek letter system.

Sri Lanka announced Friday it has confirmed its first case of the omicron variant of the coronavirus in an unvaccinated person who returned from Nigeria.

Health ministry spokesperson Dr. Hemantha Herath said the 25-year-old Sri Lankan woman returned on Nov. 24, four days before the government banned travelers from six African countries.

He said she was tested at the airport because she was unvaccinated, and the result was positive. She was sent to a treatment facility and later discharged and is currently staying at her residence, he said.

In a bid to prevent the omicron variant from entering the country, Sri Lanka banned travelers who visited South Africa, Botswana, Lesotho, Namibia, Zimbabwe and Swaziland starting Sunday.
