An elementary school in Alexandria, Virginia closed last week after more than 200 students and 30 staff members were sickened with gastroenteritis symptoms. Local health officials believe the cause is norovirus, which is easily spread and very contagious.
John Adams Elementary School was closed on March 14, 2014 for cleaning and to have all shared surfaces disinfected. The school sent a letter to parents to tell them that some students experienced nausea, vomiting, and diarrhea on Wednesday, but when many more students became ill, they decided to close on Friday.
The school was cleaned with a bleach and water solution, and the heating, ventilation, and air conditioning systems were turned off. HVAC units filters will be changed as part of the cleaning process.
