Meningitis is an infection of the membranes covering the brain and spinal cord. This covering is called the meninges.
Bacteria are one type of germ that can cause meningitis. The pneumococcal bacteria are one kind of bacteria that cause meningitis.
Pneumococcal meningitis; Pneumococcus - meningitis
Pneumococcal meningitis is caused by Streptococcus pneumoniae bacteria (also called pneumococcus, or S pneumoniae). This type of bacteria is the most common cause of bacterial meningitis in adults. It is the second most common cause of meningitis in children older than age 2.
Risk factors include:
Symptoms usually come on quickly, and may include:
Other symptoms that can occur with this disease:
Pneumococcal meningitis is an important cause of fever in infants.
Antibiotics will be started as soon as possible. Ceftriaxone is one of the most commonly used antibiotics.
If the antibiotic is not working and the provider suspects antibiotic resistance, vancomycin or rifampin are used. Sometimes, corticosteroids are used, especially in children.
Meningitis is a dangerous infection and it can be deadly. The sooner it is treated, the better the chance for recovery. Young children and adults over age 50 have the highest risk for death.
Long-term complications may include:
Call 911 or the local emergency number or go to an emergency room if you suspect meningitis in a young child who has the following symptoms:
Meningitis can quickly become a life-threatening illness.
Early treatment of pneumonia and ear infections caused by pneumococcus may decrease the risk of meningitis. There are also two effective vaccines available to prevent pneumococcus infection.
The following people should be vaccinated, according to current recommendations:
