Romania and Singapore have hit a new high number of daily COVID-19 cases as Russian authorities registered another record number of coronavirus-linked deaths.
Romanian health officials noted more than 15,000 daily coronavirus cases on Tuesday as the country's intensive care units reached capacity.
Last month, Romania had 1000 daily cases but it registered 15,037 new infections on Tuesday, almost 3000 cases more than its previous high.
The surge prompted authorities on Monday to suspend non-emergency medical treatments for 30 days to try to ease pressure on hospitals.
Raed Arafat, the head of Romania's Department for Emergency Situation, said "We do not yet see a trend of capping or falling".
Romania is the second-least vaccinated country in the European Union, with only 33 per cent of adults fully vaccinated.
It has registered more than 37,000 confirmed deaths since the start of the pandemic.
Singapore's health ministry reported 3486 new cases of COVID-19 on Tuesday, the highest since the beginning of the pandemic, while it recorded nine new deaths from the disease.
A recent spike in infections after the relaxation of some restrictions has prompted Singapore to pause further reopening.
It also tightened curbs from last week that limited social gatherings to two people and made work from home a default.
More than 83 per cent of Singapore's population has been vaccinated against the virus.
Of the nine people who died on Tuesday, three were unvaccinated, four fully vaccinated and two had received one jab, the ministry reported.
The fatalities take the death toll to 130 and the new cases mean almost 110,000 people have caught the virus in the wealthy city-state, which had until recently avoided the worst of the Delta-variant spread that had since April led to record numbers elsewhere in Asia.
Meanwhile, coronavirus-linked deaths in Russia hit a record for the third time this month and cases have exceeded 25,000 a day as vaccination rates in the country remain low.
Russia's state coronavirus task force reported 25,110 cases on Tuesday and 895 deaths.
Officials have blamed low vaccine uptake.
Only 33 per cent of Russia's population of 146 million have received at least one shot of a coronavirus vaccine and just 27 per cent have been fully vaccinated.
