A student at William Penn High School has been diagnosed with mumps, according to the Colonial School District.
In a statement issued by the district on Facebook on February 13, 2020, school officials said the last day other students at the school may have been exposed to the viral disease was January 28, 2020.
They said they contacted 16 families out of the 2,200 students at the school, that they believe are at a heightened risk due to their immunization status and provided guidance from the Delaware Department of Public Health (DPH).
Mumps symptoms can develop between 12 and 25 days after exposure and include fever, headache, body ache, loss of appetite, and swelling of parotid salivary glands--inside of the cheek, floor of the mouth, and under the tongue.
DPH advised any student, or member of a household, with symptoms to remain at home.
