South Korea will no longer require people to show proof of vaccination or negative tests to enter any indoor space starting Tuesday, removing a key preventive measure during a fast-developing omicron surge that's elevating hospitalizations and deaths. The Health Ministry's announcement on Monday came as the country set another one-day record in COVID-19 deaths with 114, breaking the previous high of 112 set on Saturday. More than 710 COVID-19 patients were in critical or serious conditions, up from 200-300 in mid-February, while nearly half of the country's intensive care units designated for COVID-19 were occupied.
