Australia's two biggest states reported sharp increases in new Covid-19 infections Wednesday, dashing hopes new lockdown measures would be eased with more than half the country's population under stay-at-home orders.

A third state, South Australia, went into its first full day of a weeklong lockdown Wednesday, and reported one new case, Channel News Asia reported.

In Indonesia, President Joko Widodo has extended the country's pandemic lockdown through the weekend, saying restrictions would be lifted gradually starting Monday if daily infections continue to drop.

In Thailand, there were a record 13,001 new cases, and 108 more deaths in the last 24 hours, health officials reported Wednesday morning.

Over in Hong Kong, more than a quarter of patients in the city had been immunized this month, most of them imported cases, South China Morning Post said.

But the Hong Kong Hospital Authority will not disclose what condition those patients who tested positive were in.

In the Philippines, stricter measures are likely to be reimposed as the Delta variant continues to pose a threat to the country, officials said Wednesday.
