South Korea reported on Wednesday its highest daily rise in novel coronavirus cases since early March as outbreaks from churches around the capital spread, prompting a warning of a nationwide wave of infections.

The 297 new infections mark the sixth straight day of triple-digit increases in a country that has managed to blunt several previous outbreaks.

The national tally rose to 16,058 infections with 306 deaths, according to data from the Korea Centers for Disease Control and Prevention (KCDC).
