Colorado Flu Cases Are Rising While COVID-19 Continues to Circulate

Flu activity is increasing across Colorado, while COVID-19 remains in circulation, according to the latest state data summary. Both respiratory illnesses can spread during the same season, cause similar symptoms, and affect households, schools, workplaces, and health care systems simultaneously. Source 1

The available summary confirms two points: Colorado flu activity is increasing, and COVID-19 continues to circulate. It does not provide a specific case total, percentage increase, hospitalization count, positivity rate, death count, publication date, or reporting period. Check the current Colorado Department of Public Health and Environment data dashboard before making precise comparisons.

For Colorado residents, the practical message is straightforward: monitor for both illnesses, do not rely on symptoms alone, and follow current public-health guidance when deciding whether to test, stay home, or seek medical care.

What the Latest Colorado Data Shows

Flu Activity Is Increasing

The latest state data summary reports increased influenza activity in Colorado. Rising activity may indicate broader transmission in communities, schools, workplaces, and households. It does not, by itself, show how severe the season is or how many people require hospital care.

Public-health agencies may track influenza through several measures, including:

• Laboratory-confirmed influenza cases
• Emergency department visits for influenza-like illness
• Hospital admissions
• Positive flu test rates
• Syndromic surveillance reports
• Outbreak reports from schools, facilities, or congregate settings

These measures answer different questions. An increase in positive laboratory tests may indicate greater circulation among people who were tested. More emergency department visits may reflect a broader increase in respiratory illness. Hospitalization data provides more information about severe disease but may lag behind community transmission.

The supplied summary confirms increasing flu activity but does not identify the measure responsible for the increase. It also does not state the number of cases or the exact period covered. Consult the latest Colorado Department of Public Health and Environment dashboard for updated figures and definitions.

COVID-19 Remains in Circulation

COVID-19 has not disappeared as attention shifts toward influenza. The same state data summary reports that COVID-19 continues to circulate in Colorado.

Ongoing circulation means people can still become infected, transmit the virus, and develop complications. A person with fever, cough, fatigue, or congestion may have COVID-19, influenza, another respiratory virus, or more than one infection.

COVID-19 trends may be monitored through indicators such as:

• Hospital admissions
• Laboratory testing
• Wastewater surveillance
• Emergency department visits
• Death reports
• Outbreak investigations

The supplied summary does not provide current COVID-19 case totals, hospitalization figures, wastewater results, or trend percentages. It supports the conclusion that COVID-19 remains present but does not support a direct comparison of the current severity of flu and COVID-19 in Colorado.

Why Both Trends Matter

Flu and COVID-19 can circulate at the same time. One virus does not automatically replace the other, and increasing flu activity does not prove that COVID-19 is declining.

The overlap matters because:

1. Symptoms are similar. Fever, cough, fatigue, headache, body aches, sore throat, and congestion can occur with either illness.
2. Self-diagnosis is unreliable. Symptoms may suggest an infection but usually cannot identify the virus with certainty.
3. Coinfection is possible. A person may be exposed to or infected with both viruses.
4. High-risk people may need early care. Some treatments work best when started soon after symptoms begin.
5. Health care demand can rise. Multiple respiratory viruses circulating together can increase visits to clinics, urgent-care centers, and hospitals.

Flu and COVID-19 Symptoms

Common Symptoms

Flu and COVID-19 can both cause:

• Fever or chills
• Cough
• Fatigue
• Headache
• Muscle or body aches
• Sore throat
• Congestion
• Runny nose
• Reduced appetite
• General weakness

Some infected people have mild symptoms, while others have no obvious symptoms but can still transmit infection. Symptoms vary by age, underlying health, vaccination history, prior infection, and the specific virus strain involved.

Because of this overlap, symptoms alone should not determine whether someone attends school, goes to work, visits an older relative, or participates in a crowded indoor event.

Symptoms More Commonly Associated With Flu

Influenza often begins suddenly. A person may feel well or mildly unwell and then develop noticeable symptoms over a short period. Flu is commonly associated with:

• Abrupt fever
• Chills
• Pronounced body aches
• Significant fatigue
• Headache
• Dry cough
• Sore throat

Not everyone with flu develops a fever. Older adults, young children, and people with weakened immune systems may have different symptoms. A gradual onset does not rule out influenza.

Symptoms More Commonly Associated With COVID-19

COVID-19 symptoms can develop gradually or appear in different combinations. They may include:

• Cough
• Sore throat
• Congestion
• Fatigue
• Fever
• Headache
• Muscle aches
• Shortness of breath
• Loss or change of taste or smell in some cases

Loss of taste or smell can occur with COVID-19, but its absence does not rule out infection. A person may also have COVID-19 without a fever or with only mild upper-respiratory symptoms.

Symptoms associated with circulating variants can change over time. Testing remains more reliable than symptom patterns alone.

Testing Helps Distinguish the Infections

Rapid and laboratory tests can help determine whether symptoms are caused by influenza or COVID-19. Availability, timing, and accuracy vary by illness and test type.

People who develop respiratory symptoms should:

• Follow test instructions carefully.
• Check the test expiration date and storage requirements.
• Consider repeat testing when recommended.
• Ask a clinician or pharmacist which test is appropriate.
• Avoid assuming that one negative rapid test excludes infection.

A negative result early in an illness may not rule out infection. A health care professional can interpret the result alongside symptoms, exposure history, and medical risk factors.

Testing can guide treatment decisions and help reduce exposure to coworkers, classmates, household members, and vulnerable people.

Who Faces Greater Risk?

Older Adults

Age can increase the risk of severe respiratory illness. Older adults should monitor symptoms closely and contact a health care provider promptly if flu-like or COVID-like symptoms develop.

Early medical advice may matter because some antiviral treatments are time-sensitive. A provider can determine whether testing, treatment, monitoring, or an in-person evaluation is appropriate.

Young Children

Young children can develop complications from influenza or COVID-19. Caregivers should monitor:

• Breathing
• Fluid intake
• Urination
• Alertness
• Fever
• Ability to eat or drink
• Changes in behavior

Contact a pediatrician when symptoms worsen, the child cannot maintain hydration, breathing becomes difficult, or the child has an underlying medical condition. Infants and very young children may require more cautious evaluation because they cannot clearly describe their symptoms.

Pregnant People

Pregnancy can increase the risk of complications from respiratory infections. Pregnant people who develop fever, cough, breathing problems, or other flu-like symptoms should seek medical advice promptly.

A clinician can assess symptoms, recommend appropriate testing, and determine whether treatment or additional monitoring is needed.

People With Chronic Conditions or Weakened Immune Systems

Higher-risk groups include people with:

• Asthma or chronic lung disease
• Heart disease
• Diabetes
• Kidney disease
• Neurologic conditions
• Severe obesity
• Weakened immune systems
• Other chronic medical conditions

These individuals should not wait for symptoms to become severe before seeking advice. Early evaluation may be important because treatment decisions can depend on when symptoms began, medical history, and test results.

What Colorado Residents Can Do

Stay Home When Sick

People with respiratory symptoms should stay home and limit close contact with others when possible. This reduces the chance of spreading infection to coworkers, classmates, household members, older adults, and people with underlying conditions.

Practical steps include:

• Improve ventilation by opening windows when safe or using air filtration.
• Avoid crowded indoor settings while sick.
• Cover coughs and sneezes.
• Wash hands regularly.
• Avoid sharing cups, utensils, towels, and personal items.
• Clean frequently touched surfaces.
• Follow current workplace, school, and public-health guidance.

Use extra caution when living with someone at higher risk of severe illness.

Consider Masking in Higher-Risk Situations

Masks can add protection in crowded indoor spaces, health care settings, public transportation, and other environments where close contact is difficult to avoid. Masking may be especially useful around people at elevated risk or during periods of increased respiratory virus activity.

Masking works best as one layer of prevention alongside staying home when sick, improving ventilation, hand hygiene, testing, and vaccination.

Keep Vaccinations Current

Colorado residents should discuss seasonal flu vaccination and current COVID-19 vaccination with a health care provider or pharmacist.

Vaccination can reduce the risk of severe illness, although breakthrough infections may occur. Recommendations may differ according to age, pregnancy, medical conditions, prior vaccination, previous infection, and immune status.

Use Trusted Colorado Health Data

Official public-health dashboards provide more reliable information than isolated social media posts or unsourced claims. Residents should check current Colorado Department of Public Health and Environment updates for:

• Influenza activity levels
• COVID-19 hospitalization trends
• Wastewater or surveillance information
• Local health advisories
• Vaccination guidance
• Changes in testing or reporting practices

Check the publication date, update date, and reporting period before interpreting a number. Data may change as laboratories, hospitals, and local agencies submit information.

When to Seek Testing or Medical Advice

Test After Respiratory Symptoms Begin

Testing may be useful when symptoms develop, especially for people at higher risk or those who live with vulnerable household members. Results may help guide treatment, exposure precautions, isolation, return-to-work plans, return-to-school decisions, and protection of older or medically vulnerable relatives.

The best testing approach depends on the illness, test type, symptom timing, and individual risk. Ask a health care provider or pharmacist for advice when uncertain.

Ask About Antiviral Treatment Promptly

Some antiviral treatments work best when started early in eligible patients. People at higher risk should contact a health care provider soon after symptoms begin rather than waiting for severe illness.

A clinician determines eligibility based on symptoms, symptom onset, test results, age, pregnancy, medical history, current medications, and risk of complications. Treatment should not be delayed solely because symptoms initially appear mild in a person with elevated medical risk.

Seek Urgent Care for Warning Signs

Seek urgent medical attention for:

• Trouble breathing
• Chest pain or pressure
• New confusion
• Severe weakness
• Difficulty staying awake
• Bluish, gray, or pale lips or skin
• Signs of dehydration
• Symptoms that improve and then suddenly worsen

For children, urgent warning signs include fast or difficult breathing, unusual sleepiness, poor fluid intake, significantly reduced urination, pale or bluish skin, seizures, or symptoms that worsen after initial improvement.

Emergencies require immediate medical attention. Do not wait for test results when serious warning signs are present.

Why Colorado Respiratory Illness Data Requires Careful Interpretation

A Rising Trend Is Not a Complete Risk Assessment

“Cases increasing” is only one part of the public-health picture. A complete assessment also considers hospitalization levels, illness severity, affected age groups, geographic differences, testing volume, reporting delays, vaccination coverage, health care capacity, and changes in surveillance methods.

The current summary confirms increasing flu activity and continued COVID-19 circulation. It does not provide enough information to determine whether flu is more severe than COVID-19, whether COVID-19 is declining, or which virus is placing greater pressure on Colorado hospitals.

Data Can Change as Reports Are Updated

Public-health figures may be revised when laboratories, hospitals, and local agencies submit delayed or corrected information. Recent numbers may be preliminary, while older numbers may become more complete over time.

Before interpreting a figure, record:

• The publication date
• The update date
• The reporting period
• Whether the figure is preliminary
• The surveillance measure used

These details help prevent misleading comparisons between numbers collected through different systems.

Avoid Comparisons Based on Incomplete Figures

The available information supports these statements:

• Flu activity is increasing in Colorado.
• COVID-19 continues to circulate.
• The supplied summary does not provide comparable case or hospitalization totals.
• Symptoms alone cannot reliably distinguish the two infections.

It does not support claims that flu is more dangerous, COVID-19 is declining, or either illness is currently dominant statewide.

Frequently Asked Questions

Is flu activity increasing in Colorado?

Yes. The supplied state data summary reports increasing flu activity in Colorado. It does not include a specific case count, percentage increase, or reporting period. Consult the latest official Colorado health dashboard for current figures.

Is COVID-19 still circulating in Colorado?

Yes. The summary reports that COVID-19 continues to circulate in the state. Residents can still become infected and transmit the virus, even when flu receives more public attention.

Can symptoms tell me whether I have flu or COVID-19?

Not reliably. Both illnesses can cause fever, cough, fatigue, headache, body aches, congestion, and sore throat. Testing and professional medical advice provide a stronger basis for identifying the infection.

Should I test for both flu and COVID-19?

Testing may be useful when symptoms develop, particularly for people at higher risk or those who live with vulnerable individuals. Ask a health care provider or pharmacist which test to use and when to take it.

When should I contact a health care provider?

Contact a provider promptly if symptoms are severe, worsening, or affecting someone at higher risk. Early advice may matter because some antiviral treatments work best when started soon after symptoms begin.

What are the emergency warning signs?

Seek urgent care for trouble breathing, chest pain or pressure, new confusion, severe weakness, inability to stay awake, signs of dehydration, or blue, gray, or pale lips or skin. For children, seek prompt care for fast or difficult breathing, unusual sleepiness, poor fluid intake, or substantially reduced urination.

The Bottom Line for Colorado Residents

Colorado flu activity is increasing while COVID-19 remains in circulation. The available state data summary confirms both developments but does not provide enough detail for precise case, hospitalization, or severity comparisons.

Use layered precautions: stay home when sick, improve indoor ventilation, consider masking in higher-risk settings, keep recommended vaccinations current, and test when appropriate. People at higher risk should seek medical advice early, particularly when symptoms begin suddenly or worsen.

Check current Colorado public-health guidance for updated respiratory illness data, and contact a health care professional for personal medical advice.
