YARMOUTH, Maine — The Yarmouth School Department received confirmation Wednesday that a student at Frank H. Harrison Middle School has been diagnosed with viral meningitis, according to a letter sent out by Superintendent Andrew Dolloff.

Earlier this month, two cases of meningitis were reported in Berwick-area schools and another four were diagnosed at Massabesic High School in Waterboro on Sept. 22.

According to Maine Center for Disease Control, meningitis is an inflammation of the tissue that covers the brain and spinal cord. Viral meningitis is the most common type of meningitis; it is often less severe than bacterial meningitis, and most people usually get better on their own without treatment.

The Maine CDC says symptoms of viral meningitis include fever, headache, stiff neck, sensitivity to bright lights, vomiting, sleepiness or trouble waking up, lethargy, lack of appetite and nausea.

According to Dolloff, the facilities maintenance staff is redoubling efforts to clean surfaces such as table tops, door handles, restrooms and locker rooms.

The Maine CDC says viral meningitis usually is not dangerous and that most people get better on their own.

However, the following precautions can help prevent the spread of many illnesses, including meningitis:

— Wash your hands often with soap and water, especially after using the bathroom, coughing or blowing your nose.

— Avoid touching your face with unwashed hands.

— Avoid close contact such as kissing, hugging or sharing cups or eating utensils with people who are sick.

— Cover your coughs and sneezes with a tissue or your upper shirtsleeve, not your hands.

— Clean and disinfect frequently touched surfaces, such as toys and doorknobs, especially if someone is sick.

— Stay home when you are sick.
