SINGAPORE - His was one of the most heart-rending stories to come from the Sars (severe acute respiratory syndrome) outbreak a decade ago.
Vascular surgeon Alexandre Chao, then 37, had rushed back from Los Angeles (LA) where he was meant to be spending a well-deserved vacation with his wife.
The date was April 5, 2003.
"One by one, his colleagues had fallen to the viral attack. He was the only 'clean' surgeon available to run the medical surgery as he had been away; so duty called," his widow, Associate Professor Koh Woon Puay, now 43, tells The New Paper on Sunday.
"Just four days before, he had persuaded me not to travel to Toronto to present a paper. There had been an outbreak of Sars and he was worried for my safety," she says, trying to hold back tears.
"I don't remember ever trying to dissuade him from returning. Not even once."
Before he left LA, Dr Chao had told his wife: "I'll be very careful. I will not put our family at risk."
That was the last time she saw him alive.
Seventeen days later, Dr Chao died from Sars at the Singapore General Hospital (SGH) where he had worked tirelessly.
"As his wife, I always supported his decisions. Then, I felt like the wife of a soldier returning to the battlefront.
" I couldn't tell him not to go, but quietly wished he did not have to."
Prof Koh, then only 33, was robbed of her soulmate; her two young daughters, deprived of their father.
Moving the box of tissue paper closer to her and pulling out a piece to wipe her eyes, Prof Koh continues.
The sequence of events is still vivid in her mind, from Dr Chao's phone call informing her he had a fever to the day he died.
She recounts: "It was April 11 and I had just returned from dinner.
"It was 10pm and as I turned the key in the lock, I could hear the phone ringing in the apartment."
She rushed to pick up the handset, and heard her husband on the other end.
"I remember his exact words: 'Dear, don't be worried. I have a fever... The protocol is to stay isolated at home for 48 hours and if the fever persists, go to the hospital.'"
Not wanting to pass the infection to his young daughters and elderly mother, Dr Chao moved into his godmother's home down the road.
"His godbrother refused to leave the house, saying he would keep an eye on Alex.
"He did, right up to the day Alex drove himself to SGH," she adds.
Prof Koh arrived from LA on Tuesday night, April15. But Dr Chao had checked himself into the hospital that morning.
They would not get to see each other again.
She says: "We spoke on the phone - constantly - to keep me updated on his condition.
"Alex was asymptomatic - he didn't have the usual signs of the infection. His lungs were clear and he wasn't breathless."
But on the morning of the day he died, Dr Chao's voice was very soft and faint, says Prof Koh.
"We had spoken at 8am, but very quickly, things got worse. He became breathless, and had to be intubated before he was pushed to the ICU (intensive care unit).
"The nurses there later told me he was smiling and waving to them, assuring them he was OK. But he wasn't. He died soon after," she says, tears rolling down her cheeks.
Prof Koh was told Dr Chao probably caught the infection from a cancer patient he was treating. The man had a fever, was breathless and was on dialysis at the hospital.
She admits that she was inconsolable but her daughters' resilience helped pull her out of depression.
"When Alex died, I told Beatrice her papa had gone to heaven and would not be back.
"Many people didn't agree with that approach, but I felt then that she was old enough to know the truth."
Now 13, Beatrice, who is in Secondary 2 at Raffles Girls' School, remembers her father as someone who was very obliging.
She recalls: "When I was young, I asked him to read 10 bedtime stories to me before sleeping. He agreed to.
"We were very enthusiastic at first but grew steadily sleepier with each page. Eventually we fell asleep after the seventh story."
Although she was too young to remember her father when he died, younger daughter Berenice, now 11, says that her favourite memory was of her father sitting on the floor in her room, eating a tub of green tea ice cream.
"I would crawl up to him and he would feed me a little bit, using my baby spoon. Till today, one of my favourite ice cream flavours is green tea, and I think it's because of my father."
Prof Koh has since remarried and the girls took to their stepfather, author George Tan, from the start. She says that when Mr Tan proposed, her daughters told her to marry him "not because you think we need a father but because you love him".
She adds that it takes a confident man to marry a woman with children and elderly parents in tow.
"He even had a bromide of an interview I did with Lianhe Zaobao on Alex framed and hung up in the bedroom. He said it was for the girls, that they keep their father's legacy alive," she asays, smiling.
Yet even after 10 years, dredging up the memories was painful.
"But I want this story told. I want our children and their children to know about this period of Singapore's history.
"Wars can be geographically contained. Infectious disease cannot - and is more devastating.
"Our children must learn to be aware of their own hygiene in order not to spread germs," she says, adding that she is glad the legacy lives on in Chinese textbooks.
"People tell me that Alex was a hero who returned when he didn't have to. But he was not the only one.
"All the doctors, the nurses and those in the forefront of Sars ; those who who died in the call of duty and those who survived despite the odds were and are very much heroes."
