The international airport uses thermal-imaging scanners to screen travelers for signs of fever. Bus and taxi drivers, who are required to take their temperatures daily, display cards in their windshields declaring, "I'm Okay."
Though no new cases of severe acute respiratory syndrome have been reported here since May, the disease has become a part of everyday life.
Some scoff at the increased vigilance, dismissing the need for mandatory temperature checks and education efforts such as the government's SARS TV channel, which went off the air only about a week ago.
"People are willing to make the small sacrifices for their own health and safety," said Jacqueline Lee, 25, who gets her temperature taken every morning at the electronics firm where she works.
"It does get to be a chore after some time, but I think it is necessary," said Paul Sim, 26, an employee at a food manufacturing company who also has his temperature checked daily.
To enter some buildings, visitors have to fill out forms leaving their contact information so they can be reached if there is another outbreak.
Workers at hotels wear dark blue buttons on their uniforms that say "COOL," a program designed to recognize establishments that have adopted anti-SARS measures ranging from employee temperature checks to more frequent cleaning. Taxi drivers carry SARS "battle kits," which include masks, thermometers, alcohol swabs and information in several languages.
The "Free Singapore from SARS" sweepstakes, which is being run by the government-sanctioned lottery operator, is offering a top prize of $1 million in a drawing next month. Proceeds from ticket sales will benefit SARS-related causes.
On the health care front, hospitals are on "orange alert," meaning that fever screenings and other precautions, including restricted visiting privileges, are still in effect. Staff members taking temperatures at National University Hospital wear masks, gloves and gowns and hand out stickers that display each person's thermometer reading for all to see.
About 10,000 patients there and at two other affected hospitals reportedly have had their medical records rechecked to make sure their symptoms didn't mimic those of the dreaded disease. Blood samples from 2,000 people who had been hospitalized as suspected SARS cases also are being collected and screened.
More than 200 people in Singapore were infected during the worldwide outbreak; 32 died here.
The effects went far beyond hospital wards. Normally bustling shopping centers were suddenly quiet. Scores of hotel rooms and airline seats were empty. Some restaurants had to close their doors. Tourism plummeted, and the island's economy sagged.
A huge government SARS relief package - worth more than $131 million - is beginning to help turn the situation around. The Singapore Tourism Board estimates that 300,000 people visited last month, compared with 170,000 in May.
During a recent stop in Singapore, the director of the U.S. Centers for Disease Control and Prevention, Dr. Julie L. Gerberding, praised the country's anti-SARS efforts as "exemplary" but warned that the disease is likely to be back.
That's the message local government officials have been trying to get out.
