No. RSV (or respiratory syncytial virus) is a common virus that infects the lungs and air passages, causing cold-like symptoms. Preemies aren’t any more likely to catch RSV than full-term babies, but it is important to note that they are more likely to have a serious illness if infected. Dr. Jennifer Gunter Q&A: Are preemies more susceptible to RSV? Not sure if they are or not, but my son (born at 34 weeks) has started the 3 rounds of a shot for RSV to hopefully prevent him from getting it. aftonswm2006 | Want to participate?
