A letter sent to parents and employees from the Mamaroneck Union Free School District announced that a Hommocks Middle School cafeteria worker who worked for Aramark Food Service employee was diagnosed with Hepatitis A and is recovering.

“We have been working closely with the Westchester County Health Department, and the Westchester County Health Commissioner Sherlita Amler, MD, has assured us that it is unlikely that anyone at the school would become ill as a result,” the letter says.

“School nurses have been instructed to keep a watchful eye for any student or staff member who may exhibit symptoms,” the letter says.

It also describes hepatitis A symptoms as fever, fatigue, loss of appetite and nausea, and says that vaccination and hand-washing are the best protections.

“If you/your child develop these symptoms anytime from today through April 23, please do not send them to school and immediately notify the school nurse,” the letter says.
