What is pneumococcal disease?
Pneumococcal disease is a bacterial infection caused by the bacteria Streptococcus pneumoniae, also called pneumococcus. It may cause middle ear infection, pneumonia, meningitis (inflammation of the coverings of the brain and spinal column) or bacteremia (a bloodstream infection).
Who gets pneumococcal disease?
Although anyone can get pneumococcal disease, it occurs more frequently in infants, young children, African Americans, some Native American populations, the elderly or in people with serious underlying medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen. Infections occur anytime but most often during the winter and early spring when respiratory illnesses are more common.
How is the disease transmitted?
Pneumococcus is spread by airborne or direct exposure to respiratory droplets from a person who is infected or carrying the bacteria.
How soon after exposure do symptoms occur?
The incubation period may vary, but, it is generally one to three days.
What are the symptoms?
Symptoms generally include an abrupt onset of fever and shaking or chills. Other symptoms may include headache, cough, chest pain, disorientation, shortness of breath, weakness and occasionally a stiff neck.
What are the complications associated with pneumococcal disease?
Death occurs in 14 percent of hospitalized adults with invasive disease. Neurologic complications and/or learning disabilities can occur in meningitis patients. Hearing impairment can result from recurrent otitis media.
How is pneumococcal disease treated?
Prompt treatment with antibiotics, such as penicillin or a cephalosporin, is usually effective. However, penicillin-resistant strains of pneumococcus are increasingly being reported throughout the United States.
Does past infection with pneumococcal disease make a person immune?
Past infection with pneumococcus does not provide lifelong immunity against pneumococcal disease reoccurring due to the many types of pneumococcal bacteria.
Is there a vaccine to prevent infection?
Yes. There are two types of vaccines currently in use. The pneumococcal conjugate vaccine (PCV13) contains protection against thirteen types of pneumococcal bacteria and can also help prevent some ear infections. The pneumococcal polysaccharide vaccine (PPV23) contains protection from 23 types of pneumococcal bacteria. Both vaccines are safe and reduce disease occurrence.
PCV13 protects infants, children and adults by preparing their bodies to fight the bacteria. PCV13 is also recommended to help prevent pneumococcal disease in adults 19 years or older with certain medical conditions and in all adults 65 years or older.
PPSV23 protects against 23 types of pneumococcal bacteria. It is recommended for all adults 65 years and older and for anyone who is 2 years and older at high risk for disease. PPSV23 is also recommended for adults 19 through 64 years of age who smoke cigarettes or who have asthma.
In New York State, pneumococcal conjugate vaccine is required for pre-kindergarten attendance for children born on or after 1/1/08.
What can be done to prevent the spread of pneumococcal disease?
One of the most effective control measures is maintaining the highest possible level of immunization in the community.
