RSV is significantly up, and is now slightly above last season’s peak. Flu is up significantly; COVID-19 is still low-ish but it has risen slightly. COVID-19 is only about a quarter of respiratory illnesses right now.
Wastewater looks about as stable as it gets.

Charts
From the BC CDC Situation Report:
Comparison vs. Other Influenza-Like-Illnesses, from the Viral Pathogen Characterization page:
RSV is still the most common infection. Note that I have no data for 21 Dec for Adenovirus, human metapneumonia, parainfluenza, or non-COVID coronavirus. It’s possible that there were zero cases of all of those, but more likely that there’s a data error. Thus, I’m going to use 21 Dec instead of 28 Dec for the following stats.
In the week ending 21 December as reported on 3 Jan 2025, among confirmed cases, there were:
- about half as many COVID-19 cases as flu cases,
- about 40% as many COVID-19 cases as RSV cases,
- about as many COVID-19 cases as enterovirus or rhinovirus cases.
- only about 25% as many COVID-19 cases as all the other influenza-like illnesses (influenza, RSV, enterovirus, rhinovirus, adenovirus, human metapneumovirus, parainfluenza, and common-cold coronaviruses) combined.
Reminder: the graphs below don’t tell how many cases there were, but how many cases they found when testing. Almost nobody gets tested — but I have no reason to believe that the percentage of sick people who get tested has changed.
