The global impact of respiratory infectious diseases and their challenges to public health systems

Abstract. Respiratory infectious diseases pose a major challenge to public health systems worldwide. Influenza is a highly seasonal respiratory infectious disease. Tuberculosis, a chronic infectious disease caused by Mycobacterium tuberculosis, remains one of the major threats to global public health. Pneumonia is a common and serious respiratory infection in children and adults. This article explores the global health impact of influenza, tuberculosis and pneumonia and the challenges they pose to public health systems. Taken together, influenza, tuberculosis, and pneumonia pose multiple challenges to global public health systems. The results show that understanding the prevalence patterns, risk factors, and social determinants of these diseases is critical to developing effective public health strategies and interventions.
