        With the availability of H1N1 Influenza A vaccine, we have seen the overall
numbers for Influenza A decline during the past few weeks. There is a possibility that
Influenza A may return for a third wave of infections, but attention has shifted to RSV as
the numbers for this virus have been on the rise of late. Concurrently the number of
detections of human Metapneumovirus (HuMPV) has also been increasing. HuMPV
causes symptoms similar to RSV.

       Both RSV and huMPV are members of the Pneumovirinae subfamily and can
cause mild to severe respiratory infections. RSV causes bronchiolitis, pneumonia, croup,
and fever and HuMPV has been associated with wheezing in children as well as
bronchiolitis and pneumonia. Both can cause serious infections in very young children
and the immumocompromised.

        Adenovirus, Coronavirus and Rhinovirus round out the list of infections present
in our community this month.
