Respiratory Viral Activity

We are seeing the end of RSV season with less than 3% positivity. There are other viruses circulating, however. Most notably Parainfluenza 3 and human metapneumovirus. We are having occasional Adenovirus as well. All of these other viruses outnumber RSV and Influenza combined!

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.
