Seoul, Dec 1 (TIWN) South Korea could make "big adjustments" to its virus prevention measures if the number of Omicron coronavirus variant cases spike in the country, a senior official said on Wednesday.

Last month, Moon said the country cannot "retreat to the past" by reversing the gradual return to normal life, hinting it may not tighten antivirus measures.  But with the increasing threat of the Omicron variant, believed to be more contagious than other variants, Park's comments suggest that options of reinforcing social distancing measures are apparently on the table depending on circumstances, Yonhap news agency reported.
