Amid the global concern over a new coronavirus strain has been one piece of hopeful news: Those infected with the omicron variant appear to have “very mild” symptoms, according to the South African doctor who first spotted the variant.

Dr. Angelique Coetzee told the BBC that neither she nor her colleagues had admitted anyone who had the strain to the hospital so far. Her patients had experienced extreme fatigue but no loss of taste or smell, which are often telltale symptoms of Covid-19, she said.

The early reports are encouraging, epidemiologists and other experts said.
