Allergologic profile of diagnosed and undiagnosed pediatric asthma in Batumi, Georgia

A population-based survey including 3239 urban children (age: 9.0±2.4 y.) in Batumi, Georgia showed a low prevalence of pediatric asthma (diagnosed asthma: 1.8%) and a follow-up clinical examination of survey participants who had no asthma diagnosis but reported asthmatic symptoms revealed 107 previously unknown cases of asthma (undiagnosed asthma: 3.3%).
