Thirty-four of Lithuania's 60 municipalities are currently in the so-called "red zone" with high COVID-19 infection rates and 21 are under local quarantines.
Lithuania's 14-day coronavirus incidence rate currently stands at almost 300 cases per 100,000 people. The country's daily count surged above 1,000 for the first time last weekend.
