Influenza Report: Flu Still Active in Kane County

Influenza Report: Flu Still Active in Kane County

The flu just keeps hanging on in Kane County, IL, neither spiking through the roof nor fizzling away.

The Kane County Health Department’s weekly influenza surveillance survey — which includes data from hospital emergency rooms, laboratories and public schools — shows the percentage of emergency room visits is still relatively high.

So far this season, there has been one infant death and 10 flu-related cases that have gone to the intensive care unit.

Participants reported the following aggregate measures in a report on Week 5, which was released Friday, Feb. 8:

Among five reporting hospital emergency rooms, 4.5 percent of visits were for influenza-like illness. During Week 5, six labs reported that 104 of 543 (19.1 percent) specimens tested for influenza were positive.

Of these 104 specimens:

  • 92 (88.5%) were positive for Influenza A
  • 11 (10.6%) was positive for Influenza B
  • 1 (1.0%) was positive for Influenza A/B

No other specimen tested positive for the week ending on Feb. 02, 2019.

During Week 5, public school districts were closed due to extreme cold, so there weren’t any statistics regarding flu-related absences.

As mentioned above, there were 10 influenza-related ICU admissions reported to the Health Department. One influenza-associated pediatric death has been reported so far during the flu season.

To date, no outbreaks of influenza have been reported in long-term care/assisted living facilities in Kane County.
