Uttar Pradesh Chief Minister Yogi Adityanath on Monday termed the Omicron variant of the coronavirus a "common viral fever", but said exercising caution is important even then. Speaking to reporters here after inspecting the COVID-19 vaccination programme for children in the age group of 15-18 years, Adityanath said, "It is true that Omicron spreads rapidly, but it is also true that as compared to the second wave (of the pandemic), the Omicron variant is quite weak. This is only a common viral fever, but caution and precautions are necessary in any disease. There is no need to panic."
