"Healthy carriers" never exhibit signs or symptoms of the disease, yet are capable of infecting others, and are often considered to be the "classic" asymptomatic carriers. [5] While the mechanism of disease carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a ...
