Indonesia, the world's fourth most populous country, aims to inoculate more than 181 million of its 270 million people by March 2022, but authorities have only fully vaccinated 11.8 million people and partially vaccinated another 9.6 million others.

National COVID-19 task force spokesman Wiku Adisasmito said the slow progress can be put down to limited global vaccine supply, the unpreparedness of the national health system and vaccine hesitancy. The government has received 92.2 million vaccine doses so far.

Indonesia saw its number of confirmed new cases climb to nearly 10,000 a day on Wednesday, an increase blamed on travel during last month's Eid al-Fitr holiday as well as the arrival of new virus variants, such as the the Delta version first found in India. In Jakarta the number of hospital beds occupied has shot up to 75% this week from 45% last week, government data shows.

The WHO in its situation report Thursday noted that Indonesia’s drastic increase in bed occupancy rates is a major concern and necessitates in the implementation of stricter public health and social measures, including large-scale social restrictions.

“With increased transmission due to variants of concern, urgent action is needed to contain the situation in many provinces,” it said.

Indonesian health officials say they've detected the Delta variant in Jakarta, Central Java and East Java provinces. They say they have spotted three of the four variants of concern flagged by the WHO.

Indonesia has reported more than 1.9 million virus cases since the pandemic began, with more than 53,400 deaths, the highest toll in Southeast Asia. Those numbers are thought to be an undercount due to a lack of widespread testing.
