A day earlier North Korean leader Kim Jong Un said the spread of COVID-19 had thrust his country into "great turmoil" and called for an all-out battle to overcome the outbreak.
Health authorities had set up more epidemic prevention posts, and urgently transported medical supplies to hospitals and clinics, while senior officials had donated reserve medicines, KCNA reported.
At least 296,180 more people came down with fever symptoms, and 15 more had died as of Sunday, the outlet said.
Experts say North Korea appears to lack the capacity to test those tens of thousands of symptomatic patients. KCNA did not report how many of those suspected cases had tested positive for COVID-19.
Overall North Korea has reported 820,620 suspected cases, with 324,550 still under medical treatment, KCNA said.
