Jakarta. Indonesia reported 949 new confirmed cases of coronavirus on Saturday, its second-highest rise in a day, to take the total number of cases in the country to 21,745 with East Java quickly becoming a new epicenter of the outbreak.

East Java again became the biggest single-day contributor of new cases with 466 to bring the province's total to 3,129.

It was the third consecutive day East Java reported the most daily cases compared to other provinces.

Over the past three days alone, East Java saw 1,099 new confirmed Covid-19 cases – 35 percent of its overall figure.

The East Java capital of Surabaya made a late start to its large-scale social restriction compared to Jakarta and West Java.

In late April, a new cluster of infections broke out at a cigarette factory near Surabaya. Two workers died from Covid-19, prompting the city administration to place more than 500 others in isolation.

The factory has since been shut temporarily.

Jakarta remains the hardest hit by the outbreak with 115 new cases on Saturday, taking the total number of infections in the capital city to 6,515.

National Covid-19 Task Force spokesman Achmad Yurianto said 25 more patients had died from coronavirus-related diseases in the 24-hour period, taking the total national death toll to 1,351.

The government doesn't include deaths from probable cases to the overall number.

"Another 192 patients have recovered from the disease, bringing the total number of recoveries to 5,249," Achmad said.

Mass testing remains an issue with just above 176,000 people having undergone polymerase chain reaction (PCR) testing since the outbreak began in early March.

Meanwhile, probable cases at hospitals (PDP) stand at 11,495 and close to 50,000 persons are still under surveillance for suspected Covid-19 infection (ODP), according to data from the task force.
