In Ohio, Ramilo is exploring a more immediate need: When young infants have high fevers, they're often hospitalized while doctors run a battery of tests to find the fraction who have a serious bacterial infection. He is leading a study involving 22 pediatric emergency rooms to see if a genomic fingerprint approach could separate which babies really need all that testing.
But the virus-or-not question is just the beginning, Ramilo said. His research suggests genomic fingerprints also can distinguish a flu strain from other common viruses. And the Duke team is analyzing a huge study of students living in dormitories, to see if the genomic test detected who was incubating the flu before their first sniffle — and thus might be useful in stemming outbreaks.
