Seroepidemiology of legionellosis in mainland China

چکیده
A comprehensive and current understanding of prevalent species and serogroups of Legionella is essential for disease detection. Through a meta-analysis of articles published from January 1982 to December 2014, we investigated the prevalence of species and serogroups of Legionella in mainland China. The study included 71 articles on legionellosis patients and 13 on asymptomatic seropositive persons. The predominant Legionella pneumophila serogroups were serogroup 1 (sg1), sg6 in patients and sg12, sg4, sg6 in asymptomatic seropositive persons. Besides, there was a statistically significant difference in the distribution of Legionella serogroups for both the patients and the asymptomatic seropositive persons between southern and northern China. Our results indicate that L. pneumophila is still the most common species in mainland China as other countries with its unique epidemiological characteristics. These data highlight the need for attention to seroepidemiological features and the choice of appropriate diagnostic methods in order to avoid missed diagnosis.
