How many people get infected by meningitis a year?

Meningitis is a serious infection of the membranes that line the brain and spinal cord. It can be caused by bacteria, viruses, fungi, or parasites. Bacterial meningitis is the most common type and can be life-threatening if not treated promptly.

According to the Centers for Disease Control and Prevention (CDC), there are about 1,200 cases of bacterial meningitis reported in the United States each year. About 10% of these cases result in death. Viral meningitis is more common and usually causes a milder illness. There are about 15,000 cases of viral meningitis reported in the United States each year.

Meningitis can occur at any age, but it is most common in children under the age of 5 and in adults over the age of 65. People with weakened immune systems are also at increased risk for meningitis.

Symptoms of meningitis can include fever, headache, stiff neck, nausea, vomiting, confusion, and seizures. If you experience any of these symptoms, it is important to see a doctor right away.

Treatment for meningitis depends on the cause of the infection. Bacterial meningitis is treated with antibiotics. Viral meningitis does not respond to antibiotics and is usually treated with supportive care.

Meningitis can be prevented by getting vaccinated against the bacteria that cause the disease. The meningococcal vaccine protects against the bacteria that cause most cases of bacterial meningitis. The Hib vaccine protects against the bacteria that cause Haemophilus influenzae type b (Hib) meningitis.

Getting vaccinated is the best way to protect yourself and your loved ones from meningitis.
