Respiratory syncytial virus (or RSV) is another respiratory infection that mainly affects little kids and circulates every year.  It occurs in the winter, like flu, but flu and RSV usually don’t peak at the same time.  Since our flu season is early this year, it looks like our RSV season may be a little later than usual.  We’ve had quite a few laboratory-confirmed cases already and we’ve let clinicians know a few weeks ago that RSV was circulating in Arizona.  There’s no vaccine for RSV but clinicians can give a preventive antibody treatment while RSV is active to those at greatest risk, like premature infants.  You can check out our weekly RSV Surveillance Report for more info.
