1. the way a disease spreads throughout a population is the:

the portal of entry

the mode of transmission

the reservoir of infection

2. the original source of a disease is the:

the mode of transmission

the portal of entry

the reservoir of infection

Solutions

Expert Solution

the portal of entry - The portal of entry refers to the manner in which a pathogen enters a susceptible host.

the mode of transmission - The ways to the spread of infection

the reservoir of infection - Any person, animal, plant, soil or substance in which an infectious agent normally lives and multiplies. The reservoir typically harbors the infectious agent without injury to itself and serves as a source from which other individuals can be infected.

1. the way a disease spreads throughout a population is the:

Some infections are spread when an infected person talks, coughs or sneezes small droplets containing infectious agents into the air. Due to their size, these droplets in the air travel only a short distance (around a metre) from the infected person before falling.

The mode of transmission is the correct answer.

2. the original source of a disease is the:

The reservoir typically harbors the infectious agent without injury to itself and serves as a source from which other individuals can be infected

The reservoir of infection is the correct answer.
