What are the two modes of transmission of disease?
Pathogens may be transferred from the source to a host by direct or indirect contact transmission and by respiratory transmission. Respiratory transmission may result from inhalation of droplets; or from inhalation of droplet nuclei, i.e., airborne transmission.
How are infectious diseases spread from person to person?
