Final answer:
Airborne transmission is the mode of disease transmission that can infect a large number of people rapidly, primarily due to the inhalation of pathogens expelled by an infected host.
Step-by-step explanation:
The mode of disease transmission that has the potential to infect a large number of people quickly is c. Airborne transmission. This occurs when pathogens contained in droplets are expelled from the respiratory system of an infected host through actions like coughing or sneezing. The pathogens can then be inhaled by nearby individuals. Diseases such as the flu and the common cold are examples of illnesses spread through airborne pathogens. Conversely, modes like vector, droplet, and direct contact, while significant, generally do not spread as rapidly to large numbers of people as airborne transmission can, especially in densely populated areas.
The mode of disease transmission that has the potential to infect a large number of people quickly is airborne transmission. This occurs when pathogens in droplets are expelled from an infected person's respiratory system during coughing or sneezing. The pathogens are then inhaled by nearby people, who become new hosts for the pathogens. For example, the flu and the common cold can spread through airborne transmission.
