Dr Julian W Tang, Clinical Virologist, University of Leicester explains the symptoms of the new variant - Omicron that World Health Organization has tagged variant of concern. He says, "Currently, we have limited data on the symptoms but from the early findings, we have seen that this virus produces more flu-like illnesses like fatigue, sore throat, a bit of shortness of breath rather than the loss of taste and smell that we see typically with Delta and Alpha variants. So, this change is maybe the indication that the virus is adapting to humans and may cause less severe disease even if it is more transmissible."
