SEOUL, South Korea (AP) — North Korea said Friday six people died and nearly 190,000 are under quarantine following a rapid spread of fever across the nation in recent weeks, a day after it first acknowledged a COVID-19 outbreak in a largely unvaccinated population.
The North’s official Korean Central News Agency said Friday that more than 350,000 people were treated for fever that “explosively” spread nationwide since late April and that 162,200 people recovered. It said said 187,800 people are being isolated for treatment after 18,000 people were newly found with fever symptoms on Thursday alone.
It wasn’t immediately clear how many of the cases were COVID-19 and the country likely lacks testing supplies. The North said one of the six people who died was confirmed to have been infected with the omicron variant.
