The isolated country has been in a heated battle against an unprecedented Covid wave since declaring a state of emergency and imposing a nationwide lockdown this month, fueling concerns about lack of vaccines, medical supplies and food shortages.
Some 88,520 more people showed fever symptoms as of Friday evening, compared with nearly 400,000 about 10 days ago, the official KCNA news agency said, citing data from the state emergency epidemic prevention headquarters.
The total number of fever patients since April rose to 3.36 million among the 25 million population. KCNA did not report any additional death. As of Friday, the death toll stood at 69.
North Korea has not confirmed the total number of people testing positive for the coronavirus, apparently lacking in testing supplies. Experts have said the announced figures could be underreported, and that it is hard to assess the actual scale of the situation.
State media said "all sectors and units" in the country are "maintaining the maximum alert and mobilized posture" to fight the virus, with authorities pushing for a "strict, prompt and advanced" medical check-ups and tests.
"Multiple protective walls have been established for the lockdown and closure of the capital city, border, front, coasts, seas and airspace to thoroughly check the inroads of new virus variants," KCNA added.
South Korea and the United States have offered to help North Korea fight the pandemic, including with vaccines, but Pyongyang has not responded.
