Textbook Question
Being habitually careful not to touch or rub your eyes with unwashed hands would reduce your risk of contracting_____.
a. chickenpox
b. infectious mononucleosis
c. seed warts
d. a cold
Verified step by step guidance1
Step 1: Understand the mode of transmission for each disease listed in the options.
Step 2: Recognize that touching or rubbing your eyes with unwashed hands primarily risks introducing pathogens that cause respiratory infections or infections transmitted via mucous membranes.
Step 3: Identify that chickenpox is mainly transmitted through airborne droplets, infectious mononucleosis through saliva, seed warts through direct skin contact, and the common cold through respiratory droplets and contact with contaminated surfaces.
Step 4: Consider that the common cold virus can be transmitted by touching the eyes, nose, or mouth with contaminated hands, making it more likely to be prevented by hand hygiene.
Step 5: Conclude that habitually avoiding touching or rubbing your eyes with unwashed hands would most effectively reduce the risk of contracting the common cold.

Intro to Characteristics of Infectious Disease
Role of Mucous Membranes in Infection
Mucous membranes, such as those in the eyes, nose, and mouth, are common entry points for pathogens. They provide a moist environment that supports microbial invasion, making them vulnerable to infections when contaminated by hands or other objects.

Common Cold and Its Mode of Spread
The common cold is caused by viruses that often enter the body through the mucous membranes of the nose and eyes. It spreads easily via respiratory droplets and by touching the face with contaminated hands, making hand hygiene crucial in reducing infection risk.
