The Philippine government extended a lockdown by another week Monday after an alarming spike in coronavirus infections continued to surge and started to overwhelm many hospitals in the capital and outlying regions.

President Rodrigo Duterte placed Metropolitan Manila and four outlying provinces, a region of more than 25 million people, under lockdown last week as daily infections breached 10,000. Roman Catholic leaders shifted Holy Week and Easter events online after all public gatherings, including in places of worship, were temporarily banned.

The government-run Lung Centre of the Philippines became the latest hospital in the capital region to announce over the weekend that it can no longer accept walk-in patients after its COVID-19 ward reached full capacity and its emergency room was handling twice its capacity.

“We are not just full. We are very full. In fact, the hospital has been full for the past two weeks,” Lung Centre spokesman Dr Norberto Francisco said.

Other hospitals said they could expand bed capacity but lacked enough medical workers partly because many had been infected.

Duterte's administration has increasingly faced criticisms of mishandling the pandemic, but presidential spokesman Harry Roque said the spread of more infectious coronavirus variants came as a surprise.

“No one could have probably foreseen how infectious these new variants are and as a result of which we have these ballooning numbers,” Roque told ABS CBN News, adding officials would inaugurate a 110-bed intensive-care unit in a hospital in the capital region Monday and were planning to launch mobile COVID-19 intensive-care centres.

The Philippines has reported more than 795,000 COVID-19 cases with 13,425 deaths, the highest totals in Southeast Asia after Indonesia.
