"Things like fatigue, headache and loss of appetite seem very important, as does the rash," RIA Novosti quoted Lloyd as saying.

He noted that rashes were almost always recorded in a small group of patients with coronavirus, but about 15% of children in whom the omicron strain was recorded had an unusual rash.

The head of the Yekaterinburg Research Institute of Viral Infections at the Vector Center of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, Alexander Semyonov, previously said that the new strain of coronavirus has a higher ability to interact with the epithelium of the lungs and provokes pneumonia faster than others.
