Recent stomach bug signals in Chicago
No matching labels appear in the available privacy-filtered breakdown. Low-count labels may be withheld, and this list does not capture every illness in the city.
Source: parent logs linked to Chicago schools and daycares on Ickly. Counts are label mentions, not unique children or cases; one log can include several symptoms. This is not citywide prevalence or public-health outbreak surveillance.
Latest local log across all illnesses: November 1, 2026. This is not the date of the latest stomach bug report.
Vomiting or diarrhea alone does not confirm norovirus. A stomach bug can have other causes, and parent-entered diagnoses are not independently verified by Ickly.
How Chicago parents can tell
- Sudden vomiting
- Watery diarrhea
- Stomach cramps
- Low-grade fever or chills
For norovirus, CDC advises staying home for at least 48 hours after symptoms stop. This is a return precaution, not the end of contagiousness: the virus can still spread for two weeks or more after recovery. Wash hands with soap and water; hand sanitizer alone does not work well against norovirus.
Local signals come from parent-entered logs, with low-count labels withheld from this city breakdown. Symptoms can have more than one cause; use your child's symptoms and medical advice alongside local reports.

When can they return to school or daycare?
For norovirus, stay home for at least 48 hours after symptoms stop, and check your school's sick policy and your clinician's advice. Feeling better does not mean the virus can no longer spread.
Watch for dehydration
Decreased urination, a dry mouth, crying with few or no tears, or unusual sleepiness or fussiness can signal dehydration. Contact your child's healthcare provider if you notice these signs or are concerned.
Reduce spread at home
Wash hands with soap and water for at least 20 seconds. Hand sanitizer alone is not a substitute for handwashing against norovirus.
