The human body is an example of this link in the chain of infection

What is a host

100

Mosquitoes, fleas, ticks, and lice spread infection through this method

What is vector-borne transmission?

100

Also called clean technique, this practice reduces microorganisms and prevents their spread.

What is medical asepsis?

What is the incubation stage?

When infectious organisms leave through the nose in respiratory secretions, the nose serves as this link.

What is a portal of exit?

300

This process eliminates all microorganisms, including bacterial spores

What is sterilization?

A person inhales infectious particles suspended in the air. Another swallows contaminated water. These are the two transmission methods involved.
 

What are airborne transmission and vehicle transmission?

400

This characteristic earns certain bacteria the nickname “superbugs.”

What is antibiotic resistance?

400

This emotional factor can increase a person’s susceptibility to infection.

What is stress?

400
