Utah weekly communicable disease report
Background: The Utah Department of Health and Human Services collects
data on over 75 communicable diseases that affect the residents of Utah.
These data are monitored by epidemiologists to detect changes in disease
activity, and guide prevention and education efforts. More information
can be found at http://health.utah.gov/epi/.
Note: Individual disease investigations take time to complete; for
this reason, data in this report should be considered provisional and
will change as more complete reports are received.
Current counts of selected reportable diseases, compared to
a historical 5-year average, week ending September 14,
2024.
Data Notes:
-
Selected diseases include the top 25 diseases reported in Utah in 2020
and excludes HIV infection, syphilis and tuberculosis.
-
Calculated by summing the counts for the current week, the 2 weeks
preceding the current week, and the 2 weeks following the current week,
for a total of 5 preceding years. The total sum of counts is then
divided by 25 weeks.
-
Averages are susceptible to skewing due to outbreaks and should be
interpreted with care.
-
YTD indicates counts are year-to-date.
-
Trend is calculated by comparing the current year-to-date count to the
5-year year-to-date average. A percent change of 15% or more will result
in a change in the trend. This should not be interpreted as statistical
significance.
-
Recent changes in laboratory practices for Cryptosporidium may account
for an increase in cases.
-
Influenza is best assessed seasonally. Weekly updates are available at

-
U: 5-yr average is Unavailable because of changes in communicable
disease reporting rules.
