what is invasive pnuemococcal disease?

Answer 1

Pneumococcal disease is caused by bacteria (Streptococcus pneumoniae) that can attack different parts of the body. The bacteria can cause serious infections of the lungs (pneumonia), the bloodstream (bacteremia) and the covering of the brain (meningitis).

Pneumococcal disease is a leading cause of serious illness in children and adults throughout the world. The disease is caused by a common bacterium, the pneumococcus, which can attack different parts of the body. When bacteria invade the lungs, they cause the most common form of community-acquired bacterial pneumonia; when bacteria invade the bloodstream, they cause bacteremia; and when they invade the covering of the brain, they cause meningitis. Pneumococci may also cause otitis media (middle ear infection) and sinusitis. Currently there are more than 90 known pneumococcal types; the ten most common types account for approximately 62 percent of invasive disease worldwide.

Answer 2

pneumococcal bacteria is part of the normal respiratory flora. At times, they can overgrow and this is what people call pneumococcal pneumonia...AKA lobar pneumonia. As with any bacterial infection, it may spread to the blood stream and this is called bacteremia. To answer the question directly, invasive can mean either local invasion (lung) or bacteremia (blood). In both cases, they are treated with antibiotics and vaccines are recommended for people with risk factors.
