On Friday, November 18, 2016, The Regional Municipality of York was notified of an unusually high number of students absent from Thornhill Woods Public School. Parents reported that children were experiencing symptoms of nausea, vomiting and diarrhea, suggesting a possible norovirus outbreak.
On November 18, 104 students were reported absent due to illness. On November 23, 54 students were reported absent due to illness, indicating the outbreak is under control.
York Region Public Health can confirm that two York Region schools, one in the Town of East Gwillimbury and one in the City of Markham, have tested positive for norovirus. A school in the Town of Georgina, along with daycare centres in the City of Vaughan and the Town of Whitchurch-Stouffville and a retirement home in the City of Vaughan have reported increased illnesses with symptoms that are typical of a norovirus-like illness.
“Outbreaks of norovirus and other enteric viruses, those which cause vomiting and diarrhea, are common at this time of year. In fact, norovirus is the most common cause of gastroenteritis outbreaks worldwide,” said Dr. Karim Kurji, York Region’s Medical Officer of Health. “Norovirus outbreaks are common in semi-closed environments such as schools, childcare centres and retirement homes. The numbers we are seeing across the Region are no greater than in previous years.”
Norovirus is a highly contagious viral illness that comes on quickly and usually resolves within 24 to 48 hours. There are no long-term effects from norovirus. Antibiotics are ineffective as they are with most viral infections.
In order to prevent the spread:
-
Anyone experiencing symptoms should stay home for at least 48 hours after symptoms stop
-
Thoroughly wash hands with soap and water, especially after using a toilet or changing diapers and before preparing, handling and eating food
-
Wear gloves when cleaning up vomit or diarrhea
-
Remove and wash clothes and linens that may be contaminated with vomit or feces
-
Keep sick individuals out of areas where food is being handled or prepared
-
Anyone who is sick should not handle or prepare food for at least 48 hours after symptoms stop
