Streptococcus pneumoniae is a major cause of pneumonia, among infants and children in Japan and worldwideThis study plans to investigate the rate of invasive pneumococcal disease "IPD " and the rate of hospitalizations due to pneumonia in Okinawa and the Eastern half of Hokkaido Currently, only a limited information about pneumococcal disease burden is available in Japan.
1.Describe the distribution of causal pathogen of meningitis and bacteremia 2.Estimate the hospital admission rate of pneumonia patients 3.Estimate the incidence rate of IPD 4.Describe the serotype distribution of S. pneumoniae [ Time Frame: 2 years ]
Secondary Outcome Measures
1.CFRof patients admitted with IPD and/or pneumonia. 2.Antibiotic resistance rate of S. pneumoniae 3.Risk factor distribution 4.Average duration of the hospitalization of patients with IPD, meningitis, and/or pneumonia. [ Time Frame: 2-3 years ]
