“…Our results confirm the high incidence of pneumococcal infections in young children observed in other studies (6,29). A recent study of invasive infections in children under 5 years of age in west Africa estimated that the incidence of invasive infection was 240/100,000/year in children younger than 5 years and 554/100,000/year in children younger than 1 year (18).…”

All clinical S. pneumoniae specimens isolated from patients with invasive or sterile-site infections admitted to one regional general hospital in southern Chile were collected during a 5-year period (February 1994 to September 1999). A total of 247 strains belonging to 50 serotypes were isolated in this survey: 69 in patients under 5 years of age, 129 in patients 5 to 64 years old, and 49 from patients 65 years and older. Eight serotypes were identified in all age groups, while all other serotypes were found exclusively in one age group or in patients over 4 years of age. Serotype 3 was never found in patients under 5 years old, and serotype 14 was not found in patients >64 years of age. There was no difference in the serotypes causing infection in each one of the 5 years of the survey. Our results suggest that both bacterial virulence factors and host factors play an important role in the selection of S. pneumoniae serotypes causing invasive infection. Possible host factors include age-related differences in the immune response. Comparative studies with other areas of the world may help to further understanding of our observations in southern Chile.

“…The incidence of invasive pneumococcal disease is influenced by age, immunization status, and ethnic background (11). Our results further confirm the high incidence of pneumococcal infections in young children that has been observed in other studies (5,33). This observation suggests that there should be a continuous program of monitoring invasive pneumococcal infections.…”

“…These rates that are 4-6 times higher than those found among nonindigenous children in those regions. Indigenous persons in the circumpolar north have been shown to have high rates of IPD (1,2,5,15,(19)(20)(21), as have other indigenous groups such as Aboriginal Australians (22), White Mountain Apaches (23) and Navajos in the southwestern United States (24), Maoris of New Zealand (25), and the bedouins of Israel (26).…”
