Stomach illness outbreak moves school district in southwest Chicago suburb to e-learning
A school district in the south suburbs is moving to an e-learning day on Friday due to a widespread illness.
The Troy Community Consolidated School District 30-C announced the decision to keep students home after a "stomach illness spread to students and staff.
"Symptoms reported are consistent with acute gastroenteritis, a general term used to describe stomach illness. There has not been a confirmed diagnosis of a specific illness," School officials said in a written release.
The district is in contact with the Will County Health Department and will follow their guidance. All district buildings will be sanitized during winter break.
Local health officials said it's the most common time of year for illnesses like norovirus to spread. Here's what you need to know.
Symptoms and signs of norovirus
Norovirus is actually a group of related viruses that affect the intestinal tract to cause stomach illnesses, according to the Illinois Department of Public Health.
Onset of symptoms typically occurs between 24 and 48 hours after exposure.
Symptoms include vomiting, diarrhea, nausea and abdominal pain, as well as body aches, headache, tiredness and low-grade fever.
Patients usually remain symptomatic from 24 to 60 hours after onset, IDPH said. Health officials say anyone with symptoms needs to stay home for at least two days after symptoms end.
How is norovirus spread?
Humans are the only source for noroviruses to grow and spread, and they cannot multiple outside the human body, IDPH said. The viruses live in the feces of an infected person, and can be transmitted if the infected person doesn't thoroughly wash their hands after a bowel movement.
That includes handling food that is not later cooked (raw foods like salads, or already-cooked foods liked baked goods that do not subsequently need to be heated to temperatures that kill viruses are examples). Food heated to cooking temperatures will kill the virus.
You can also become infected if you consume water contaminated by sewage with the virus present, or from ice made from contaminated water. Raw shellfish from contaminated water can also transmit noroviruses.
Person-to-person contact with someone who is infected and has not properly washed their hands also spreads the virus. IDPH said there is some evidence the norovirus can also be spread by vomit particles lingering in the air, or contact with objects contaminated by fecal material.
How to prevent the spread of norovirus
According to the CDC, the best way to prevent the spread is hand washing with soap and water. Hand sanitizer does not kill or work to prevent the spread of virus. Hands should be washed for at least 20 seconds in with soap and hot water.
The CDC recommends washing hands before eating or handling food. This also includes washing hands after using the toilet or changing diapers.
The CDC also recommends:
- Wait at least 48 hours after symptoms stop to prepare or handle food for others.
- When dealing with contaminated items, wash with detergent and hot water at the maximum available cycle length and then machine dry them at the highest heat setting.
