Cohort study in north east Thailand


In a cohort study in northeast Thailand the health status of 602 preschool children was checked every 2 weeks from June 1982 until September 1985 (Schelp et al. 1990). In this time period it was recorded how often the children showed symptoms of fever, cough, running nose, or these symptoms together. The frequencies of these illness spells are given in the data set.
