• Droplet Transmission

• Vector Transmission

An infected individual coughs into the air, then an uninfected individual inhales the particles, acquiring the pathogen. This form of disease transmission is an example of:

• Direct Contact

• Indirect Contact

• Droplet Transmission

• Vector Transmission
