RALEIGH — More than 1,900 people were treated at a free health clinic over the weekend, after a second case of meningitis was confirmed at Leesville High School on Friday.

As a precautionary measure, the Wake Co. Health Department set up a screening and antibiotic station for people who came into contact with the student.

Health officials do not think the latest case is related to another meningitis case reported at the school the week before. That student has already recovered.

The latest case was diagnosed asmeningococcal meningitis, an infection of the fluid of a person's spinal cord and the fluid that surrounds the brain. It is usually caused by a viral or bacterial infection.

Symptoms often include high fever, headache and stiff neck. They can develop over several hours or as long as two days. Other symptoms may include nausea, vomiting and sleepiness.

Letters about the latest case went home with students Friday.
