Flu Summary
This report is intended to provide an overview of influenza related activity occurring in Cuyahoga County while
providing some information on state activity that is one week behind the current week. It will be published on a
weekly basis and can be found at the following website: http://www.ccbh.net/flu-weekly-reports/?rq=flu
Note: Data are provisional and subject to change. Updates will be included in future reports.
Pneumonia and Influenza (P&I) Mortality
2.0% of all deaths reported to the Cleveland Bureau of Vital Statistics were due to pneumonia. Adults 75 years old
and older accounted for 66.7% of all pneumonia related deaths. No influenza related deaths occurred this week
(Figure 1).
Influenza-Like Illness (ILI) Reports
Athenahealth reported that 0.20% of patients had flu-like symptoms this week. No sentinel providers reported this
week. (Figure 2). ILI is defined as a fever (≥ 100◦ F), and cough and/or sore throat.
Influenza-Associated Hospitalizations and Influenza-Associated Pediatric Mortality
Two confirmed cases of influenza-associated hospitalization in Cuyahoga County was reported this week (Figure 3).
Forty-seven statewide confirmed influenza associated hospitalizations in week 19. Six statewide pediatric flu related
deaths occurred in this flu season.
School Absenteeism
Participating schools in Cuyahoga County reported the percentage (median = 2.1%) of absenteeism due to any illness
on Tuesday (Figure 4A). Figure 4B shows the total absenteeism due to any reason (median = 6.1%).
Emergency Department (ED) visits and Over-the-Counter Medication Sales
2.3% of all ED visits were for fever + ILI symptoms. Approximately 70 more patients visited EDs for fever and ILI
symptoms this year compared to the 5-year median (Figure 5). Figure 6 shows approximately 160 more OTC products per drugstore were purchased this year than the 5-year median for products purchased in the same time period.
Three other maps show, by zip code, the frequency of ED visits for three symptoms that are common during the fall
and winter seasons and are of interest to the general public: congestion and cough (Figure 8), vomiting and nausea
(Figure 9), and diarrhea (Figure 10).
Descriptions of data sources used to complete the weekly influenza write-up can be found on the last page of this
report.

Board of Health. Data are preliminary.
Sources of Influenza Surveillance Data
Six types of data sources are examined on a weekly basis to help determine the influenza activity level for
Cuyahoga County:
1) Ohio Department of Health (ODH) Seasonal Influenza Activity Summary : The ODH influenza
summary provides state-wide data . Data used from this report include: frequency of fever plus influenzalike illness (ILI) associated hospitalizations, number of influenza-associated pediatric mortalities, and
number of lab-confirmed influenza cases.
A) Influenza-associated Hospitalizations (ODRS): Influenza-associated hospitalizations are reported
by the Cuyahoga County Board of Health (CCBH) and hospitals using the Ohio Disease Reporting
System (ODRS). Hospitalizations can be used as an indicator of the severity of illness during a
particular influenza season. This condition became reportable in January 2009.
B) Influenza-associated Pediatric Mortality (ODRS): Influenza-associated pediatric mortalities are
reported into ODRS by CCBH and hospital staff. Pediatric deaths can be an indicator of the severity
of illness during the influenza season. This condition became reportable in 2005.
C) Sentinel Providers (ILINet): Sentinel providers, through the US Influenza-like Illness Surveillance
Network (ILINet), collect outpatient influenza-like illness (ILI) data. ILI is defined as a fever (> 100
F), and cough and/or sore throat without another known cause. Providers report the total number of
patients seen, by age group, on a weekly basis. Sentinel providers also submit specimens for influenza
testing to the ODH laboratory throughout the influenza season. There are 3 sentinel providers enrolled
in Cuyahoga County for the 2014-2015 season.
D) ODH Laboratory Surveillance: The Ohio Department of Health Laboratory reports the number of
specimens that test positive for influenza each week. Generally, specimens are submitted by sentinel
provider participants. A subset of the positive specimens is sent to CDC for further testing during the
season.
2) Mortality Reporting System (Cleveland’s Vital Statistics): Cleveland Vital Statistics office reports on
deaths that occur in 55 of 59 municipalities in Cuyahoga County (excludes Lakewood, Bedford, Euclid, &
Parma) regarding pneumonia & influenza.
3) ILI data (athenahealth) "ILI estimates are based on insurance claims diagnoses, documented in athenahealth's database. athenahealth is a healthcare technology and services company for electronic health
records, medical billing, patient engagement, and care coordination."
4) School Absenteeism data (due to illness and due to any reason): More than 50 Cuyahoga County
schools provide absenteeism data for each Tuesday on the number children absent due to any illness or
due to any reason as well as sentinel schools that report week absenteeism data.
5) National Retail Data Monitor (NRDM)-OTC Drug Purchases: The NRDM collects over-the-counter
(OTC) drug sales information from Cuyahoga County chain drug stores and grocery stores. Pediatric cold
products, anti-fever products, and thermometer sales are monitored on a weekly basis.
6) Emergency Department Visits (EpiCenter): EpiCenter collects emergency department chief complaint
data from hospitals and urgent care facilities across Cuyahoga County and classifies them into symptom
and syndrome categories. Rates for chief complaints regarding fever + ILI and other symptoms commonly
detected during the winter are analyzed.
