The holidays mean spending more time with family, but this time of year it can also mean more germs and sickness.
Oklahoma doctors are warning of a rise in respiratory syncytial virus or RSV.
Doctors at Saint Francis are reporting that this is a "very bad" year for it.
Anyone can get RSV, but it is especially hard on babies and children under two.
Doctors say it is the number one cause of pneumonia and lower respiratory infections.
"Not a lot you can do to prevent RSV other than good hand washing, avoiding people that are sick, and stress that people shouldn't be kissing on babies." said pediatrician John Lukeman.
Doctors say there is really no treatment for RSV.
The symptoms are fever, runny nose, cough, and wheezing.
