Get Your Flu Shot

Everyone 6 months of age and older should get an influenza (flu) vaccine every season. Vaccination to prevent flu and its potentially serious complications is particularly important for people who are at higher risk of developing serious flu complications.  Call 970-248-6900 to schedule an appointment for a flu vaccine.

Mesa County Flu Hospitalization Meter

This meter shows weekly flu hospitalization intensity in Mesa County for the current flu season compared to historical data.

Influenza and Influenza Like Illness (ILI) Intensity Meter

This meter displays the extent to which flu and flu-like illness are reasons patients are visiting a healthcare provider in Mesa County for the current flu season.

2021-2022 Influenza Season Severity Measures:

For the 2021-2022 influenza season, Mesa County Public Health (MCPH) uses the Moving Epidemic Method for determining influenza season severity. Based on data from past influenza seasons, MCPH uses key influenza indicator data to develop intensity thresholds (ITs) to classify the severity of influenza seasons from low to very high. The indicators chosen to capture influenza severity in Mesa County include:

  1. Number of influenza-associated hospitalizations (IAH).
  2. Percentage of influenza and influenza-like illness patient visits reported to MCPH defined through the collection of ICD-10 codes.

Hospitalization Intensity Meter:

The Hospitalization Intensity Meter utilizes historical influenza hospitalization data in Mesa County to determine the intensity levels currently occurring in the county. Hospitalization intensity below the IT40 is considered “Low” and shown in dark green. Intensity between IT40 and IT90 is considered “Medium” and shown between light green and orange. During a season, we expect 60% of weekly values to be light green or above and expect 10% of values to be red or above. This methodology was published by CDC researchers in the American Journal of Epidemiology in October 2017.

Flu and Flu-Like Illness Intensity Meter:

The Flu and Flu-Like Illness Meter utilizes historical influenza visit data from our sentinel reporting partner, Primary Care Partners, to determine the intensity levels of influenza and influenza-like illness visits in Mesa County. The same formula for the Hospitalization Meter applies to the Flu-Like Illness Meter – visit intensity below the IT40 is considered “Low” and shown in dark green. Intensity between IT40 and IT90 is considered “Medium” and shown between light green and orange. During a season, we expect 60% of weekly values to be light green or above and expect 10% of values to be red or above.

Flu Incidence Rate:

This chart is created by calculating the hospitalization incidence rate in Mesa County by CDC disease reporting week, which run from Sunday-Saturday. Incidence rate is the number of new cases per population in a given time period, which is then typically multiplied by 100,000 to allow for comparisons across groups that do not have the same population. In this case, the number of new hospitalizations during the previous week is divided by Mesa County’s population and then multiplied by 100,000. This chart is not age-adjusted. Population estimates are provided by the Department of Local Affairs.

Flu Hospitalization Rate by Age Group:

This chart is created by calculating the total hospitalization incidence rate by age group in Mesa County. Incidence rate is the number of new cases per population in a given time period, which is then typically multiplied by 100,000 to allow for comparisons across groups that do not have the same population. In this case, the number of new hospitalizations by age group is divided by Mesa County’s population of that age group and then multiplied by 100,000. This chart is not age-adjusted. Population estimates are provided by the Department of Local Affairs.

Mesa County Cumulative Influenza Hospitalizations:

This chart is created by calculating the total amount of hospitalizations due to influenza in Mesa County by CDC disease reporting week, which run from Sunday – Saturday. This chart compares the previous 4 years and represents total numbers (not rates) of people hospitalized due to influenza in Mesa County.

Western Slope Age-Adjusted Hospitalization Rates Map:

The Western Slope hospitalization map compares influenza hospitalization rates between counties on the Western Slope. These rates of hospitalization are age-adjusted using the Colorado Department of Local Affairs 2021 county age estimates for age groups: 0-4, 5-17, 18-24, 25-49, 50-64, 65+ to the regional population distribution of the current flu season. Age-adjusting allows public health to compare influenza activity between counties of differing size and age distributions. Total hospitalization counts are also included for comparison.
