Question

It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.

Answer 1

Yes. It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.

The human upper respiratory tract serves as a reservoir for a diverse community of commensals and potential pathogens, such as Haemophilus influenzae, Moraxella catarrhalis,etc. which can occasionally develop into pathogens and cause infectious diseases. Viruses are responsible for the majority of upper respiratory tract infections.

Nasal hairs are used to catch debris. Particles are propelled upward and out of the respiratory tract by cilia on the epithelium of the trachea and bronchi. The respiratory system has a feature that guards against infections.

Therefore, It is common for a normal, healthy individual to carry potentially pathogenic organisms in their upper respiratory tract.
