Researchers find novel RSV variant responsible for prolonged infection

Researchers found a novel respiratory syncytial virus variant responsible for prolonged infection in infants.

The study, published in the Journal of Infectious Diseases on Nov. 15, analyzed genetic sequences of healthy infants and the RSV virus causing their prolonged infections. 

Researchers found a genetic marker in the RSV DNA that was associated with prolonged infection. They found no genetic susceptibility in the infants that led to an extended infection, according to the study.
