Respiratory virus infections (original) (raw)

Respiratory virus infections pose significant public health challenges due to their prevalence and associated morbidity and mortality, particularly among young children in less developed countries. Key viruses affecting the respiratory tract include influenza, adenoviruses, RSV, and coronaviruses, which often exhibit seasonal distribution patterns. Accurate diagnosis relies on laboratory confirmation, as clinical symptoms alone are insufficient for distinguishing between viral infections. Despite advances in diagnosis, the development of effective treatments and vaccines remains a critical objective.
