Since the beginning of the year, Omicron has been the dominant variant of COVID infection worldwide. Due to its high transmissibility rate, the variant was able to take over the aggressive Delta variant within no time.
Although its rate of transmission is the highest among all variants so far, it has a mild effect on the infected individual; less severity and low hospitalization rates have been seen since Omicron became the dominant variant.
The common signs of COVID as seen in Omicron infections are sore throat, fever, runny nose, muscle pain and fatigue. Loss of smell and taste which was commonly seen during the earlier waves of COVID infection was not seen during the Omicron wave.
