What's Going Around in Rockford?
Fast local read for Rockford, powered by Illinois surveillance plus city context lower on the page — August 2026
Fast answer
What matters first in Rockford
For a quick "what illness, virus, or sickness is going around in Rockford?" check, start with the weekly respiratory picture. Flu, RSV, and COVID-19 are low in Illinois statewide surveillance for the week ending Aug 22, 2026. Low does not mean zero, and the signal cards below show exact values. Public dashboards do not identify every ordinary cold or local cluster. Measles appears separately as approximate statewide case context, not a Rockford case count or formal outbreak determination.

State-level disease surveillance plus slower city-level community context
Best For
Quick local infectious-disease orientation before deeper chart review
Use the top half of this page for the latest statewide signals relevant to Rockford, not exact city case counts. Public dashboards do not identify every ordinary cold or local cluster. The lower community-context section is older CDC PLACES data about respiratory burden and access to care, included to explain possible impact rather than current spread.
Secondary context
Community context that can change impact
This does not tell you what is spreading this week. All reported weekly respiratory signals are low, but this context helps explain who could feel a future respiratory wave harder in Rockford. The measures below use CDC PLACES city estimates from 2022.
Respiratory burden
11.2%
Asthma
Higher asthma prevalence can mean more people feel respiratory surges harder.
Chronic lung disease
8.3%
COPD
COPD can raise the stakes when respiratory infections rise, especially for older adults.
Access to care
14.5%
Uninsured
Higher uninsured rates can make prevention, testing, and treatment harder to reach quickly.
Preventive care reach
77.1%
Annual Checkup
Routine checkups make vaccination, follow-up, and early care easier when illness is spreading.

Frequently Asked Questions
What illnesses are going around in Rockford, Illinois right now?
Flu, RSV, and COVID-19 are low in Illinois statewide surveillance for the week ending Aug 22, 2026. Low does not mean zero, and the signal cards below show exact values. Public dashboards do not identify every ordinary cold or local cluster. Measles is shown separately as 4 cases in the current state tracker view in the approximate Illinois tracker through Aug 25, 2026; that is not a Rockford case count or formal outbreak status.
Is the flu bad in Rockford right now?
Flu activity in Illinois (which includes Rockford) is currently low with 0.4% ILI. A current CDC Rt direction estimate is unavailable; use the weekly ILINet trend on the state flu page. See the Illinois flu page for weekly trend charts.
Why does this page include city-level community context?
The lower community-context section does not show what is spreading this week. It uses CDC PLACES (2022 data) to show slower-moving local vulnerability and access-to-care patterns in Rockford, such as asthma burden or uninsured adults, so the infection data has clearer local context.
Does Rockford have its own health data, or is this state-level?
This page combines two types of public-health data. Flu, COVID-19, RSV, and measles use Illinois statewide surveillance as context relevant to Rockford; they are not exact Rockford case counts. The lower community-context section adds slower Rockford-specific CDC PLACES estimates about respiratory vulnerability and access to care. Public dashboards can miss ordinary colds and small local clusters, so use local health-department notices for confirmed local events.
