This is the highest spike since late August when the country reported 323 cases.
Hospitals are feeling the pinch of this sudden increase in cases.
ICU beds have reached almost 80-percent capacity, leaving only 119 intensive care beds available.
The bed shortage is most acute in the greater Seoul area, Gangwon-do province, and Jeollanam-do province.
Some experts are even saying that South Korea is at the start of a third wave of the outbreak.
“There have been a total of three infection waves. The one in Daegu and Gyeongsangbuk-do Province, the outbreak in August, and the outbreak now. The latest infections are taking a toll on the medical capacity, so it’s apt to see the current situation as the third wave.”
181 of the Wednesday’s local transmissions were from the greater Seoul area.
Seoul city alone saw 91 cases.
Some recent clusters in the capital include a sports facility in Seongdong-gu district, a sauna in Seocho-gu district, and a hiking club.
Research centers for Samsung Electronics in Suwon, Gyeonggi-do Province and LG Electronics in Seoul also each reported one of their workers had tested positive.
The buildings have been closed down to prevent the infection from spreading to other employees.
Experts say that an outbreak in the capital is especially dangerous as the region is home to more than half of South Korea’s population, and the virus could spread quickly through the densely populated region.
