CDPHE has added an 11th case, likely the suspected case from Friday’s announcement. No further information is available at this time.

Hey Colorado, In today's wastewater data, there's a SHARP uptick in RSV & COVID, that is not (as of yet) reflected in the trends. COVID is back up near our winter peak, RSV is the highest all season. While this is partial data, it's concerning enough that I wanted to highlight.

Two, possibly 3 more measles cases in the Broomfield outbreak:

Hey Denver Metro! You may have seen the news about the outbreak of HPAI H5N1 at a Weld County poultry operation in the last few days. Are you also aware that there have been infected birds found all over the Denver Metro area?

Dear good guys, We will win. youtu.be/cXhVWMKQPjQ

masking is just about collective care. we should *always* mask in health care settings.

New HPAI #BirdFlu outbreak in Weld county Colorado. This sounds like it might be at the a facility that had an outbreak in July 2024. (Part of a double outbreak that infected 10 humans) There have been warnings about HPAI H5N1 in the wild bird population in the area kdvr.com/news/local/v...

"If we already have good reason to believe a treatment works, randomizing people to a placebo means knowingly denying them benefit. That’s not science. That’s harm in the name of methodological purity." This. 1000x.🔥 Going to forward to a local gang RCTing portable HEPA units. In hospital rooms.

I just spoke with the White House after another horrific shooting by federal agents this morning. Minnesota has had it. This is sickening. The President must end this operation. Pull the thousands of violent, untrained officers out of Minnesota. Now.

COVID, Flu & RSV in Colorado update, 1/21/25* Holiday Week Flu hospitalizations continue to fall away. Other early indicators are also dropping. RSV appears to be rising, Covid looks flat. The holiday has likely depressed totals, but the situation has clearly improved!

No NPR, I do not want to wake up to Trump incoherent belligerent self aggrandizing rambles with out interruption. Ever. I understand this is news. But Im trying to start my day not ostrich under the covers and refuse to move.

I’m seeing posts from people (outside of MN) about how US citizens should carry their passports. And let me say that *inside* MN, we are calmly responding to requests with: “No, I don’t have to show you any documentation.” Because that’s how you protect everyone, regardless of immigration status.

COVID, Flu & RSV in Colorado update, 1/14/25 Flu hospitalizations have dropped significantly, but remain higher than the peak in an average pre-pandemic year. Other early indicators like Positivity and ED visits have also dropped. COVID & RSV are low but climbing slowly

Funny how basic airborne infection controls (masking, HEPAs, window cracked 2cm) are framed as a "burden," while the burden of being repeatedly exposed to Covid is dismissed as anxiety & goes unacknowledged

If you won't listen to us, maybe you'll listen to this horse.

This is a WILD set of headlines. 1. Pediatric Flu deaths are higher than ever, 2. They are strongly associated with being unvaccinated, 3. Pediatric vaccinations have been steadily dropping, & 4. RFK Jr removes flu vaccines from the pediatric vaccine recommendations 🤦‍♀️ #MAHA

If everyone wore n95 respirators at conventions, there'd be basically no such thing as "con crud". Remember this when you're recovering from Covid or "Some Kind Of Bad Flu... Not Covid™️ Though" after MFF. sph.umd.edu/news/study-s...

New flu map from the CDC is up: its now bad everywhere and darkest level “very high” in 1/4 of the states. Oof

CDC data show ~11% of U.S. pediatric flu deaths in 2024–25 occurred despite full vaccination. This shows vaccines certainly help, but without clean air, masking and sick-leave policies etc, some kids are still left vulnerable. Pediatric flu deaths are a policy choice www.cdc.gov/mmwr/volumes...

COVID, Flu & RSV in Colorado update, 12/31/25* Holiday Week Flu has blown past previous records for weekly hospital admissions. More people were hospitalized for flu last week than any week these records have been kept (ie, since 2004). There is no sign of slowing yet.

“We're continuing to see steadily increasing numbers of kids with the flu with no end in sight,” said Dr. Shen Nagel. www.cpr.org/2025/12/31/c...

Nearly 800 people (782) in Colorado are now hospitalized with flu, that’s almost 250 more than a week ago, 430 more than two weeks ago and 12 times the number the state recorded in mid-November. www.cpr.org/2025/12/31/c...

Holy Moly Colorado! Flu data updated early. The previous record was in 2014, when 582 people were hospitalized in a single week. We just eclipsed that week by a full 34% (and the data for last week remains incomplete)! #flu #viralillness #maskup

COVID, Flu & RSV in Colorado update, 12/23/25* Holiday Week Partial Update Flu is now in record-setting territory. More people were hospitalized for last week than all but one week in the last 10 years. Positivity & ED Visits are sky high. Kids continue to be hit HARD.

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! 😷

COVID, Flu & RSV in Colorado update, 12/17/25 COVID has some rising indicators, but remains relatively low. RSV has begun rising. Flu is the BIG story. Hospitalizations are now very HIGH, positivity & ED Visits are up, the first pediatric death in the state has been recorded.
