SEOUL, South Korea — South Korea’s streak of more than 1,000 daily coronavirus cases has reached a week as health authorities scramble to slow a viral surge that has brought Seoul’s thriving nightlife to a standstill and professional baseball to a halt.

Authorities said Tuesday that more than 800 of the 1,150 new cases are in the greater capital area, where officials have shut down nightclubs and prohibited private social gatherings of three or more people after 6 p.m.

There are signs the virus is spreading beyond the Seoul metropolitan area as the country enters its summer holiday period. Busan, Daegu, Daejeon and South Chungcheong Province are among the major cities and regions that reported dozens of new infections.

South Korea has added more than 13,000 cases this month alone, bringing its total for the pandemic to 170,296, including 2,046 deaths from COVID-19.
