Eighty-five percent of people in Singapore are fully vaccinated, and 18 percent have received booster shots.

But the Singaporean government said Monday that it will no longer cover the medical costs of people “unvaccinated by choice,” who make up the bulk of remaining new coronavirus cases and covid-19 hospitalizations in the city-state.

“Currently, unvaccinated persons make up a sizable majority of those who require intensive inpatient care, and disproportionately contribute to the strain on our health care resources,” the Ministry of Health said in a statement Monday.

“Covid-19 patients who are unvaccinated by choice may still tap on regular health care financing arrangements to pay for their bills where applicable,” the ministry added.

The government now foots the bill for any Singaporean citizen, permanent resident and holder of a long-term work pass who is sick with covid-19, unless they tested positive shortly after returning from overseas.

“This was to avoid financial considerations adding to public uncertainty and concern when covid-19 was an emergent and unfamiliar disease,” the Health Ministry said in its statement.

“Until the covid-19 situation is more stable,” it added, it will continue to cover related medical costs for those who are vaccinated, as well as for those still not eligible: children 12 and under and people with certain medical conditions. Partially vaccinated people in Singapore will be covered until Dec. 31.

Asia is slowly reopening to travelers. Here’s where you can go.

Singapore is considered to have one of the world’s the best health-care systems. A 2017 study in the leading medical journal the Lancet found that Singapore ranked first among 188 countries in efforts to meet health-related sustainable development goals set by the United Nations for 2030.

The Singaporean model, however, depends heavily on privatized medical services, meaning that the unvaccinated may already have coverage if they become sick with covid-19. In the United States, for example, about one-third of health-care spending is private, while in Singapore it is the opposite, according to an analysis by the New York Times.

Moreover, workers in Singapore are mandated to put a portion of their salaries away in health savings accounts, which employees are also required to contribute to based on varying criteria.

Under this system, bills for the unvaccinated will still be “highly supported and highly subsidized,” Health Minister Ong Ye Kung told a news conference Monday, Yahoo News reported.

“Hospitals really much prefer not to have to bill these patients at all,” Ong said. “But we have to send this important signal to urge everyone to get vaccinated if you are eligible.”

Singapore recorded some 91,000 new coronavirus infections over the past 28 days, 98.7 percent of which were asymptomatic or mild cases, according to the Health Ministry.

As of Nov. 7, 1,725 people were hospitalized with the virus. Of those, according to the Health Ministry, 301 have required oxygen, 62 are under close monitoring in the intensive care unit and 67 are critically ill and intubated. That has put Singapore’s current ICU use rate at 68.5 percent.

“While this is still manageable by stretching our health care manpower, we must not let down our guard and must avoid a resurgence of cases that could once again threaten to overwhelm our health care system,” the Health Ministry said Monday.

Early in the pandemic, Singapore relied on extensive surveillance, contact tracing and strict movement restrictions to keep virus cases low. The heavily surveilled city-state has since begun easing some virus-related restrictions.

Correction: An earlier version of this story said that 85 percent of people eligible for coronavirus vaccination in Singapore are fully vaccinated. Eighty-five percent of Singaporeans overall have been fully vaccinated. The error has been corrected.

Coronavirus: What you need to know

Covid isolation guidelines: Americans who test positive for the coronavirus no longer need to routinely stay home from work and school for five days under new guidance planned by the Centers for Disease Control and Prevention. The change has raised concerns among medically vulnerable people.

New coronavirus variant: The United States is in the throes of another covid-19 uptick and coronavirus samples detected in wastewater suggests infections could be as rampant as they were last winter. JN.1, the new dominant variant, appears to be especially adept at infecting those who have been vaccinated or previously infected. Here’s how this covid surge compares with earlier spikes.

Latest coronavirus booster: The CDC recommends that anyone 6 months or older gets an updated coronavirus shot, but the vaccine rollout has seen some hiccups, especially for children. Here’s what you need to know about the latest coronavirus vaccines, including when you should get it.
