Coping with a cold is usually not a life-threatening emergency, but a couple in South Bay say that may be the reason their son died.
Mark and Belle Ang have been in shock for two weeks after the sudden death of their 9-year-old son Tristan, healthy, dynamic and athletic.
Doctors believe that Tristan's death may be due to a rare complication of colds or adenovirus.
"They said that, unfortunately, one of the complications is that it can go to the brain," said Mark Ang.
"Waking up every morning is a struggle for us," added Belle Ang. "At night, you can not sleep."
The Angs said it started a week before one of Tristan's Taekwondo competitions. The third grader, who attended Marshall Pomeroy Elementary School in Milpitas, was a big fan of the sport and a black belt. Mark said that Tristan had become a little weak, a little tired, with headaches, fever, nausea and vomiting.
The doctors sent them home from hospital, saying that he was just dehydrated. But a few days later, he started to look stunned and had trouble saying his own name.
"I was so worried, worried about telling my dad, can you keep an eye on the other two, we will still go to the ER," said Mark Ang.
Once in the intensive care unit, Tristan's brain began to swell and soon his heart stopped. Four times.
"After the fourth departure, the doctor told Belle and me that he was dying," Mark said. "As a nurse, I know, but as a father, I do not want to believe it."
In less than 3 hours, Tristan was gone.
Neither Mark nor Belle, the two nurses, could believe it.
"We are angry at ourselves, what did we miss?" Belle said.
The Angs have two other young children, but Tristan was their firstborn and they had tried to be 14 years old.
The family wanted to donate Tristan's organs to another patient but said he was not eligible because he had the adenovirus.
A GoFundMe page launched on July 1 on behalf of the Ang family raised nearly $ 8,000 on a $ 10,000 goal on Thursday night.
