Measles in colorado continues to climb: 4 more cases tied to the Broomfield outbreak

To sum it all up,
RSV is high & Flu B is rising.
Broomfield has a Measles outbreak, affecting 2 schools.

Early Measles symptoms resemble flu. Please stay home/mask up if symptomatic.

Consider seeking vaccination if undervaccinated.

Masks are helpful against Measles!

There is no change in the detection status of Mpox in wastewater, but 2 new Mpox cases have added in the last week.

There is no Measles being detected in Colorado wastewater at this time, but the utilities serving the affected area are no longer part of the Sentinel Surveillance system (Broomfield, Louisville, South Adams). These utilities were part of the Lab phase 1 surveillance program.

CDPHE reports a 3rd measles case associated with the Broomfield high case, this one in a child who apparently attends Broomfield Heights Middle School.

With 3 connected cases, this is officially an outbreak.

These exposures seem to be the earliest thus far, making this case 1.

Flu B levels are particularly high, with 8 utilities above median levels, and Boulder levels so high they are off the chart.

Durango, Fort Collins, and Greeley are all also particularly high.

The wastewater data is mixed, with COVID trends dropping, but levels climbing this week.

Flu B and RSV in wastewater are at nearly season-long highs.

Pediatric Flu Hospitalizations remain elevated, and RSV hospitalizations climb.
Children's Hospital's Bugwatch reports slight dips in pediatric positive specimens in their patients.

Flu Positivity and RSV are climbing, with no sign of slowing.

Flu B Positivity is driving the increase in overall Flu Positivity.

Hospital Admissions (comparing to initial #s for last week)

Covid: 72, down from 89 last week.
Flu: 141, up from 133
RSV: 325, up from 301

Flu B is now the predominant Flu variant circulating, and flu admissions have stopped sliding as Flu B surges.

COVID, Flu & RSV in Colorado update, 3/4/26

RSV continues to climb.
Flu hospitalizations climb slightly as a Flu B wave grows. Covid dips slightly.

Measles cases grow and the first outbreak of 2026 is confirmed.

Holy moly.

It really is. I dont think this person was infected by the last case. I think they were both infected by someone else who hasnt been identified yet (due to the timing…). Which means there may be a bunch more coming soon. 😭

Another #measles case at Broomfield HS just outside Denver.

You’re a washington guy, how will your experience in washington help you protect Colorado from the worst impulses of the current administration?

Yeah. Its not feeling great here 😭😭😭😭

Omg. We can also add an outbreak of Legionnaires:

Yeah. Me waking up today from a nightmare where a kid showed up to my sons’s birthday covered in spots makes more sense now… 🤦‍♀️😭

And for the first time since the dashboard has been up, Mpox Clade has been detected in wastewater.

Mpox Clade II was detected in wastewater in Colorado Springs - Las Vegas Utility.

There has been a case of Measles in a Broomfield high school student. There have been a LOT of exposures in Broomfield, Louisville and Lafayette.

Unvaccinated exposed students are being told to stay home.

Its been a bad day for Pubic Health in colorado.

Measles.
Mpox.
An entire School district closed for illness.

Ellicot School District (east of the springs) is closed for illness and cleaning. No info on why.

Woooow! Well, that is in fact good public health policy.

Ugh. So sad.

Fifth Colorado child dies from flu this season Doctors say they're seeing what a heavy toll a bad season can take as Coloradans generally lag the nation in vaccine rates.

"This serves as a tragic reminder that influenza is not just a routine illness — it is a serious disease," said Dr. Rachel Herlihy, the state epidemiologist. www.cpr.org/2026/02/26/f...

Late extra note: The Flu B levels this week (53 admissions) Appear to equal the highest number recorded in any week in the last two years. I dont have precise totals for 2024, but it doesnt look like totals were ever more than a few admissions over 50.

To sum it all up?

RSV is continuing to run wild, Flu B is ramping up.

There has also been another significant Measles exposure at DIA and a Littleton church.

Early Measles symptoms resemble the Flu, please mask up to protect others if you develop symptoms.

The wastewater data looks a little funky again, with 80% of all reports from all utilities on 2/17 below detectable levels. The data looks a little fishy.

COVID trends and levels are down, Flu A detections are down. Flu B Detections are up. RSV detections hold steady.

Pediatric Flu Hospitalizations climb, as a Flu B wave begins in the Pediatric population.

RSV remains very high with no sign of slowing.

Children's hospital also warns of a wave of pneumonia as a secondary infection from strep infection in their patients.

This flu season is now the 2nd worst on record, behind only last year.

More concerning, the Flu B wave is looking concerning. We've had more Flu B admissions (197) this year than ALL last year (186).
There's a chance we will meet last year's record if the Flu B wave continues.
