Molecular epidemiology of influenza, RSV, and other respiratory infections among children in Qatar: A six years report (2012-2017).

摘要: Abstract Background Studies on the etiology of respiratory infections among children in Qatar and surrounding countries are limited. Objectives To describe prevalence seasonality RSV, influenza, other pathogens Qatar. Methods We retrospectively collected analyzed data 33,404 ( Results At least one pathogen was detected 26,138 (78%) patients. Together, human rhinoviruses (HRV), syncytial virus (RSV), influenza viruses comprised nearly two-thirds all cases, affecting 24%, 19.7%, 18.5%, respectively. A 5-10% recorded for adenovirus, parainfluenza (PIVs), bocavirus (HboV), coronaviruses (HCoVs). Human metapneumovirus (HMPV), enteroviruses, M. pneumonia, parechovirus had prevalences below 5%. While HMPV exhibited strong seasonal activity winter, HRV active during low RSV circulation. The burden exceeds that young age groups, whereas correlated positively with age. Further, HRV, infection rates varied significantly between male females. Conclusion This comprehensive multi-year study provides insights into ILI Qatar, which represents Gulf region. Our results reinforce significance surveillance to improve prevention control strategies, particularly children.
