Hi M.,
It is very responsible of you to be concerned for your niece. It's amazing the parents who just don't care about anybody else's children! Just so you know, I'm a nurse, specializing in ER and neonatal nursing. Since RSV is viral, antibiotics do not help and the only treatment is fever control, keeping their noses and throats clear of that yucky mucous and keeping them hydrated. First I want to tell you there are a few different types of RSV. One acts like the common cold but just seems worse in a baby because they can't clear their own noses and lungs and throats. The other is a type of RSV that is the dangerous kind and will send infants to the hospital. There is no way to know which is which unless tested and watching and waiting to see what happens. Studies are still ongoing for the creation of tests to determine exactly what type of RSV a child has. By the age of 2 years, a child will not be diagnosed with RSV any longer, but just the common cold or flu symptoms. RSV of any type is highly contagious, as is a cold (boy, do we all know that!). Of course the #1 thing is handwashing and then disinfecting anything that babies touch and anything that goes in their mouths....which is just about everything! As far as your niece goes, the symptoms to look for are any cold/flu symptoms, any difficulty breathing, flaring of the nostrils when breathing, ribs pulling in when breathing, color changes, decreased appetite, fevers, junky coughs. They don't really need to be seen by a physician unless the fever is uncontrollable by Tylenol and lukewarm baths, if they truly are having the nasal flaring and pulling in at the ribs with breathing, or if they start to look blue. And certainly anytime they stop breathing or become lethargic and listless either call 911 or head for your nearest emergency room. I guarantee you there is no way to stop kids from being exposed or getting RSV or colds, so don't blame yourself for the exposure. If it wasn't your child who exposed her, it would have been someone else! But I do applaud your concern. Take care, and BTW, be sure to do your best to keep everyone out of your baby's face for a while until he/she is all better. Like I said, it's nearly futile, but it does pay to be responsible about it anyway. God bless.
