IBV is ticking up in Ottawa wastewater as expected at this time of year, but unexpectedly RSV is still going strong. Interestingly, clinical surveillance trends are lagging.

The ww data is feeding the %infected metric and is calculated based on a set epidemiological model that takes into account infection latency and how long it takes a case to resolve. Essentially %infected should mirror the ww signal but is a bit less sensitive to changes…less bumpy.
