Currently, scientists at the Karolinska Institute say, a cause for up to 40 percent of the lower respiratory infections that affect children can't be determined. But in studying hundreds of respiratory tract samples from a paediatric infectious disease ward, they used sophisticated DNA testing to identify a parvovirus tentatively named HBoV.

Writing in the current issue of the Proceedings of the National Academy of Sciences, the researchers said 17 of the samples tested positive for HBoV.

The scientists also suggested that the DNA screening methods they used to identify and test for the virus be used to reveal other germs that have yet to be identified. – (HealthDayNews)
