Which of the following is NOT a method of disease transmission?

Passive resistance is not recognized as a method of disease transmission. Instead, it refers to the resistance an organism may have towards a disease due to a lack of active engagement with infectious agents. In contrast, the other options listed, such as vector transmission, airborne transmission, and direct contact, are all established methods through which diseases can spread.

Vector transmission occurs when a disease is transmitted through a living organism, often insects, that carry pathogens from one host to another. Airborne transmission involves pathogens that are carried in the air and can infect individuals who inhale them. Direct contact describes transmission that occurs when an infected person makes physical contact with another person, transferring pathogens directly.

Understanding these transmission methods is crucial for EMTs, as it informs their approach to infection control and patient care, helping to mitigate the spread of disease in a prehospital setting.
