ISLAMABAD — Pakistani authorities on Sunday reported only four new COVID-19 fatalities in the past 24 hours, the fewest deaths since March.

The announcement raises hopes that Pakistan is on the right path to fully containing the coronavirus despite having a fragile health system.

The National Command and Control Center also reported 591 new cases, increasing the country’s caseload to 275,836, including 6,275 deaths.

Pakistan witnessed a sudden spike in infections and deaths in June, but confirmed cases and fatalities have gradually declined since then. The latest development comes days after Pakistan’s drug regulatory agency approved final-phase testing of a Chinese-made coronavirus vaccine.

Pakistan hopes it will get the vaccine on priority from neighboring China if its clinical trials show success.
