Question

A communicable or contagious disease: a) Will always be subclinical. b) Can be spread from one host to another. c) Will always exhibit physical symptoms. d) Cannot be spread from one host to another.

Answer 1

Communicable or contagious diseases can be spread from one host to another, and they do not always exhibit physical symptoms or become subclinical. Not all infectious diseases are communicable, like tetanus which cannot be passed from an infected person to another.

Step-by-step explanation:

The correct response to the question about communicable or contagious diseases is that they can indeed be spread from one host to another (option b). This is because communicable, contagious diseases are as a rule capable of being spread from person to person. An example of this is measles, which is a highly contagious disease that can be transmitted through the act of an infected person coughing or sneezing, after which an uninfected person breathes in droplets containing the virus.

However, such diseases do not always exhibit physical symptoms (option c is invalid). For instance, diseases like herpes simplex virus infection can be asymptomatic, implying that no noticeable signs or symptoms are presented. Such diseases can also be subclinical

Furthermore, not all infectious diseases are communicable (option d is false). Tetanus, for example, cannot be passed from an infected person to another individual. It is transmitted only via contact with a skin wound.
