Born in 2008, Bella was diagnosed as having an extra chromosome, this rare defect is know as Trisomy 18 a severe genetic disorder that leads to abnormal brain and major organ development with only a 1 out of 10 survival rate in the first year of life.
Santorum and his family were taking a few days off from the campaign trail in Virginia celebrating the Easter holiday weekend when Bella became ill and taken to the hospital.
Communications director for the Santorum campaign Hogan Gidley said in a statement Friday
"Rick and his wife Karen have taken their daughter Bella to the hospital. The family requests prayers and privacy as Bella works her way to recovery."
This is the second time baby Bella was admitted to the hospital this past year. Bella had been briefly hospitalized with pneumonia in January which prompted Santorum to take a short leave from the campaign trail to be with his family just days before the Florida primary.
Karen Santorum has been critical of the media for (as she believes) misstating the severity of her daughter’s condition saying in an interview on CNN
earlier this year:
"It's funny, reading articles when people actually write about my little girl and they really aren't accurate at all, what they're saying. People have said that she has a terminal illness and she doesn't. Her life is fragile but Bella's doing great, she's strong, she's healthy right now and I thank God for that."
Santorum said Friday he plans to resume campaigning come Monday.
UPDATE: According to CNN
Rick Santorum has decided he will spend Monday with his daughter instead of returning to the campaign trail.
UPDATE 4/10/12: Rick Santorum has suspended his campaign.
