What are the underlying causes of a lung illness that is not contagious yet has similarities to tuberculosis?
Infection with certain mycobacterial germs, also known as nontuberculous mycobacterial lung disease, is the root cause of nontuberculous mycobacterial lung disease. These microorganisms are widespread and can be discovered everywhere outside.
Which of the following is the most significant factor in the development of pharyngitis among the available answer choices?
