Respiratory infectious diseases are primarily infectious illnesses caused by pathogens entering the human body through the nasal cavity, trachea, pharynx, bronchi, and other respiratory system components. Pathogens include bacteria, viruses, mycoplasmas, and chlamydia, mainly transmitted through air, droplets, and contact.
Respiratory infectious diseases spread rapidly, posing significant challenges to prevention and control. Severe respiratory infectious diseases such as the Spanish Flu, SARS, Middle East Respiratory Syndrome (MERS), and the widespread impact of the coronavirus have posed significant challenges to economic and social development. Consequently, the prevention and control of respiratory infectious diseases have garnered heightened attention.
