This is where I got the "mild" symptoms from-
"The South African doctor who first alerted authorities to the presence of the COVID-19 omicron variant reported that it presents "unusual but mild" symptoms.
Dr. Angelique Coetzee, a board member of the South African Medical Association, first noticed otherwise healthy patients demonstrating unusual symptoms on Nov. 18.
"Their symptoms were so different and so mild from those I had treated before," Coetzee told The Telegraph."
