‘Very high’ levels of flu cases reported in Illinois amid ‘significant winter surge’

Hospital admissions and positive tests for influenza are soaring in Illinois, prompting warnings and concerns from health officials.

According to an update Monday from the Illinois Department of Public Health, flu activity in the state has climbed to “very high” levels in recent days, the most severe of five categories of respiratory illness activity used by the CDC.

Data available via the IDPH’s Seasonal Respiratory Illness Dashboard shows that more than 19% of emergency room visits in Illinois during the last reporting period were due to acute respiratory illness, with more than 18% of hospital admissions attributed to those illnesses.

Acute respiratory illnesses include the flu as well as COVID-19 and RSV, according to officials.

COVID-19 rates are also on the rise, increasing to “moderate” levels in the state according to the CDC.

The CDC uses wastewater monitoring to help detect viruses infecting people in a community, according to its website.

The bulk of hospital admissions and ER visits associated with respiratory illnesses were made because of flu symptoms, according to officials.

Health officials in Illinois are warning of a new and unexpected mutation that could make for a “more serious flu season.” Natalie Martinez has more.

Data shows that the spike in illnesses is having a serious impact on those residents under the age of 18. Children between the ages of 5 and 17 are most impacted by hospital admissions related to acute respiratory illnesses and the flu, while residents over the age of 65 are most impacted by COVID-19.

In the press release, Illinois also reported its first influenza death in a child this season.

“Illinois is facing a significant winter surge in seasonal respiratory illnesses with flu activity at very high levels,” Dr. Sameer Vohra, IDPH director, said. “Vaccinations remain the most effective tool to prevent severe illness from flu, COVID-19 and RSV.”

That push for vaccinations comes as approximately 22% of state residents have received flu shots, according to Illinois health officials. Even though flu season peaks in January and February, officials caution that it can last into May, making vaccination a smart strategy in containing spread of the illness.

In addition to vaccines, washing hands frequently is critical to preventing spread of the illness, as is covering coughs and sneezes, and wearing a mask when ill.

Antiviral treatments can also minimize symptoms and speed up recovery, but must be sought in the early stages of the illness to be effective, officials warn.
