RSV in rapid decline

Over the last three weeks RSV has predictably declined in Southern California. As is evident from the graph, we have fallen from persistently endemic levels of 23% the week ending March 19 to a current level of 5%. We are continuing to see occasional influenza (mostly influenza A) as well as parainfluenza, adenovirus and human metapneumovirus. Stay tuned to see if the anticipated decline continues.
