Giardia Incidence rate

This indicator shows the Giardia Incidence rate per 100,000 population. Giardia intestinalis (also known as G. lamblia and G. duodenalis) is the most common intestinal parasite of humans identified in the United States. It causes a generally self-limited clinical illness (i.e., giardiasis) typically characterized by diarrhea, abdominal cramps, bloating, weight loss, and malabsorption; asymptomatic infection also occurs frequently. Case reports and epidemiologic studies have associated giardiasis with the development of chronic enteric disorders, allergies, chronic fatigue, and reactive arthritis.

Understanding the color Range

Each Health Indicator includes five-color range indexes. The color range index compares all counties in the state that have the same indicator in the same timeframe. It then calculates where the selected county falls in that range and displays the color that best reflects how the county is doing in comparison to the other counties in the filtered group. The range displays the highest and lowest county values within the state that have the same indicator for the same measurement period.

Current county values will be compared to State and National values if they are available.

Green and red arrows indicate that the county value is better or worse than the state or national value. The arrows will change directions and colors based on which end of the range is positive.
This icon simply means that the county value is equal to the state or national value.
Some indicators display blue, which means the data is not meant for health-status comparison, but is intended simply to provide information.
If history data is available the trend icon will point up or down based on its relationship to the last county value.
