Question

multiple choice question
a disease is ______ when an infected host can transmit the infectious agent to another host and establish infection in that host.
o infectious
o virulent
o noncommunicable
o communicable

Explanation:

• Infectious: Refers to a disease caused by an infectious agent, but doesn't necessarily imply transmission between hosts.
• Virulent: Describes the severity or harmfulness of a pathogen, not transmission.
• Noncommunicable: Means the disease cannot be transmitted between hosts, which is the opposite of what the question describes.
• Communicable: By definition, a communicable disease is one where an infected host can transmit the infectious agent to another host and establish infection.

Answer:

communicable
