I want to contextualize the flu situation right now in #Colorado:
Less than 20 weeks have ever recorded more people hospitalized for Flu in the state than last week, going back as far as 2014. (Most were last year, the worst flu year ever)
AND Last Weeks total (334) is still incomplete data!

Wastewater trends for COVID have really turned upward, with 14 of 21 utilities now increasing. Levels remain relatively low.
Flu in wastewater is being detected in 20 of 21 utilities.
Levels in wastewater are not keeping up with the very high levels of hospitalizations.

Pediatric cases are also very high:
Children's hospital reports over 500 positive tests for Flu A last week.
They also report that the flu being detected is H3N2 subclade K, which is causing severe illness in other countries, especially in the unvaccinated.

Pediatric Flu Hospitalizations continue to be concerning.
71 hospitalizations this past week is 21% of all hospitalizations statewide.
Last year, pediatric hospitalizations only represented 16% of hospitalizations over the season; we are now at 85% of last year's peak.

To Sum it all up?
There's a LOT of flu around and a lot of people are needing to go to the hospital.
Use layered protection strategies to avoid illness, including: hand washing, vaccines, air filtration, ventilation, & respirators like N95s to reduce your chance of catching the flu!

Flu has risen statewide, with levels now above median in 9 of 21 utilities. Levels in Highland Ranch, Fort Collins, Metro-CC, and Aurora are particularly high for those utilities (Though Fort Collins does not have last year to compare to).
The statewide average is climbing FAST!

One concerning thing is that Flu detection in wastewater remains very low.
(averaging only 3000 copies/liter).
When hospitalizations were this high last year (between Dec 21 (162) and Dec 28 (353), Wastewater flu detections were MUCH higher (above 10000 copies/L)
