Similar to Delta mutant strain, Omicron mutant strain also has strong transmission and pathogenicity, and its characteristics such as short infection incubation period and rapid onset process have formed a rapid spread in the world.
Symptoms of Omicron infection and protective measures
Symptoms of Omicron infection mainly include muscle soreness and fatigue, accompanied by a slight cough, or no obvious symptoms. So far, no symptoms of loss of taste and smell have been found in infected people.
