New case fatal, but meningitis not epidemic

A second case of meningitis in Park County has proven to be fatal, but is not related to the first case in February, according to Park County Health Officer Charles Jamieson, M.D.
The two cases were caused by different strains of bacteria that are not connected.
“We do not have an epidemic of bacterial meningitis in our community,” he said. “People should just take this as a reminder that life is precious and use common sense to help prevent disease.”
A 15-year-old Cody High School student, whom Dr. Jamieson did not identify, died Saturday after he was diagnosed with meningitis last week.
The boy had a sinus infection for about two days before symptoms worsened and he sought medical care. He was seen in the emergency room Thursday where it was determined he had meningitis. He was taken by air ambulance to Denver and died Saturday.
“It was a complication of a primary infection that overwhelmed the immune system before it could be treated,” Jamieson said. “He had a run-of-the-mill infection that got more aggressive and crossed into his brain.”
The second case comes just a few weeks after a 15-year-old female at CHS was diagnosed with meningococcal meningitis. She is back at school and expected to make a full recovery.
“The only common denominator is they happened to attend CHS,” he said. “They didn't go in the same circles or attend the same classes.”
The first case was caused by Neisseria Meningitidis, which is a bacterial form that can be contagious to close contacts. It is preventable by a vaccine. Anyone who came in close contact with the girl was given antibiotics and no new cases have occurred from that incident.
But the second case doesn't have the same characteristics and is an isolated incident, Jamieson said. It could not have been prevented by the available vaccine because it wasn't caused by the same bacteria.
“They're having difficulty finding the organism,” Jamieson said. “They're exhausting all their resources trying to identify one.
“It could have been any bacteria that caused a sinus infection and damaged the lining and allowed it to cross to the brain.”
Meningitis is caused by exposure to specific aggressive bacteria, much like the first case, or by a complication of a common infection like sinusitis, as in the second case, Jamieson said.
It is an inflammation of the tough, protective tissue surrounding the brain and spinal column. It's caused by an infection that has crossed the blood-brain barrier.
“A bad sinus infection can go on for weeks and weeks in one person,” Jamieson said. “In another person it's 24 hours and if it gets into the wrong place (the brain) it has free rein.”
The two most common causes are viral and bacterial, both of which can be contagious, but only to people with prolonged close contact with the patient, or an exposure to the patient's bodily fluids or secretions.
The signs and symptoms of meningitis (or spinal meningitis) are an extremely ill patient with headache and stiffness of their neck and back. There is commonly a fever, but it may not be high. There may be other symptoms of sinusitis, upper respiratory illness and even rashes.
The only way to diagnose meningitis is by a physician doing a spinal tap and taking a sample of the spinal fluid for lab analysis.
Since the cases have two different causes, Jamieson said the community should not be alarmed about an epidemic of infectious meningitis.
People can protect themselves from communicable diseases by using good hand washing techniques and limiting exposure to other people when sick. Staying home from work or school, as well as places where people congregate such as church and stores, is recommended.
Anyone with concerns or signs of meningitis such as progressive illness with fever and stiff neck should seek medical attention for definitive diagnosis and treatment.
Vaccination is available to prevent meningococcal meningitis for children ages 12-18.
To get the vaccine contact a physician's office or Public Health, 527-8570.
