North Korea has once again reported zero positive cases of COVID-19 after another week of testing, according to the World Health Organization (WHO), as Seoul pushes to send humanitarian aid to the North following the restoration of inter-Korean hotlines.

In its weekly situation report, the WHO said the DPRK tested a total of 681 people using polymerase chain reaction tests from July 16 to 22, including 109 people with flu-like illness or acute respiratory infections and 572 health care workers.
