Age distribution of diarrhoeal and healthy children infected with Campylobacter jejuni.
The prevalence of infection with Campylobacter jejuni in diarrhoeal and healthy children (age less than 7 years old) was investigated from 1 March to 31 May 1988 in Chengdu city, China. The isolation rate in diarrhoeal children (11.88%) was higher than in healthy children (4.62%) (P less than 0.005). In both diarrhoeal and healthy children, infants (less than 12 months of age) had lower rates of infection than older children (P less than 0.005 and P less than 0.05 respectively). The frequency of C. jejuni was lowest in diarrhoeal children aged less than 6 months, highest in those aged 12 to less than 24 months. The isolation rate in healthy children was also lowest in those aged less than 6 months, and no difference occurred among age groups of greater than 12 months. Our results show that the isolation rate in diarrhoeal children was rising with increasing age up to 12 months of age, tending to stabilize with increasing age after 12-24 months of age in Chengdu, China.
