epidemiology of pneumococcal disease Pneumococcus is one of the main causes of bacteraemia and meningitis in reported cases (1)
- each year around 5,000-6,000 cases of invasive pneumococcal disease (IPD) are reported to the Health Protection Agency, Centre for Infections (2)
- in UK, the annual incidence of IPD is approximately 12 per 100,000 population (3)
- a marked seasonal pattern can be observed with majority of cases occurring in December and January each year
According to laboratory confirmed cases in England and Wales from the period 1996-2005, 5.5% of reported cases of invasive pneumococcal disease (IPD) were meningitis (4)
- out of 252 laboratory-confirmed cases of pneumoccal meningitis during 2004/2005
- 74 (29.3%) were children 1 year of age and younger
- 100 (39.6%) were adults 45 years of age and older (4)
In addition to IPD, in England and Wales each year there were
- an estimated 40,000 hospitalisations due to pneumococcal pneumonia
- 40,000 GP consultations for pneumococcal related community acquired pneumonia
- over 63,000 for pneumococcal otitis media (2)
