The Facts on Pneumococcal
Disease
What is pneumococcal
disease? Pneumococcal
disease is cause by Streptococcus
pneumoniae, a bacterial pathogen that affects infants, children, and
adults. The bacteria cause sinus and middle
ear infections, meningitis, pneumonia, and invasive infections of the
blood. S. pneumoniae is the most common cause of bacterial meningitis in
infants and children in the United States.
There are 83 different types of these bacteria, but 23 types account for
90% of pneumococcal infections. Strains
of drug-resistant S. pneumoniae have
emerged in recent years, making treatment much more difficult. Pneumococcal disease causes more than 40,000
annual deaths. Together with influenza
infection, it is the 6th leading cause of death in the United States.
Who gets pneumococcal
disease? All
children and adults are susceptible, but children younger than 2 years of age
and adults 65 years of age or older are at increased risk. Persons with sickle cell disease and those
whose spleen has been removed surgically are a highest risk because they have
difficulty removing S. pneumoniae
from the bloodstream. Each year in the
United States, pneumococcal disease is responsible for an estimated 7 million
cases of middle ear infection; 500,000 cases of pneumonia; 50,000 cases of
life-threatening blood-borne infection; 3,000 cases of meningitis.
How is the disease spread? By droplet spread
(sneezing), by direct oral contact, or indirectly via articles soiled with discharges
from the nose or mouth of infected persons.
Person-to- person spread commonly occurs, but illness among casual
contacts is frequent. Persons with
susceptible strains of S. pneumoniae become noninfectious within
24-48 hours after penicillin treatment begins.
What are the symptoms of
pneumococcal disease? Fever,
vomiting, and seizures may be the first symptoms in infants and young
children. Fever, ear pain, or sinus
congestion occur in older children and adults.
Shaking chills, fever, chest pain, productive cough, and rapid or
labored breathing may suddenly appear.
When do symptoms appear? Usually within 1 to 3 days
after exposure.
How is pneumococcal disease
diagnosed? Cultures
from blood, spinal fluid, or pus confirm the diagnosis.
What is the treatment? Cases of blood-borne
infection or bacterial meningitis possibly or proven to be caused by S.
pneumoniae should receive combination therapy with vancomycin and cefotaxime or
ceftriaxone. Middle ear infections and
sinusitis usually are treated with oral amoxicillin.
How can pneumococcal
disease be prevented? Pneumococcal
vaccine protects against 23 strains of S. pneumoniae that cause 90% of the
illness. Anyone aged 65 years or older
should receive the vaccine. Anyone
whose spleen has been removed surgically also should receive the vaccine. Persons aged 2-64 years with immune
deficiency, heart, lung, or liver disease, diabetes mellitus, alcoholism,
spinal fluid leaks, or sickle cell disease should receive the vaccine. It is not effective in children younger than
2 years of age.
