Colorado residents are facing an early start to flu season that already includes a confirmed child death. Health officials say the virus is spreading faster this year than last, prompting a push for immediate vaccination before the holiday gatherings begin.
The Colorado Department of Public Health and Environment confirmed the first pediatric influenza-associated death of the 2026-27 season. The victim was an elementary-aged child. State Epidemiologist Rachel Herlihy reported that flu activity is rising across the country. Colorado is seeing these cases earlier than in the previous year.
Herlihy noted that the 2025-2026 season was the worst on record since tracking began in 2004. That previous season saw the highest hospitalization rates for children. It also recorded more pediatric deaths than any season since the 2009 H1N1 pandemic. This context shapes the current urgency as new cases appear.
More than one million Coloradans have already received the flu vaccine this year. Herlihy stated that this number puts the state ahead of where it stood in the last two years. The vaccine is available to anyone six months or older. It is recommended for children, pregnant people, and those with underlying health conditions to reduce the risk of serious illness.
Community members are acting on the advice to protect their households. Christopher Leo said he views vaccination as a way to look out for one another during social circles in the holidays. He wants to protect people when they are in close contact. His perspective aligns with the public health goal of reducing transmission in homes and gatherings.
Pharmacists are seeing a corresponding shift in foot traffic. Steve Musielak of CVS reported a sharp increase in patients coming in for shots in the last week or two. He noted that it takes up to two weeks for the full effect of the vaccine to kick in. Musielak advised people not to wait, stating that the time to get vaccinated is right now while the virus is circulating.
The early arrival of the virus means the window for building immunity is shorter before peak transmission. Officials and pharmacy staff alike emphasize that waiting reduces the protection available during high-risk periods. The current data shows a clear trend toward earlier infection and higher vaccination uptake compared to recent history.
