A disease like small pox or the plague is described as

• A. Infectious and contagious
• B. Noninfectious
• C. Noncommunicable
• D. Zoonotic

Answer: (A)

A disease that can spread from one person to another is described as infectious and contagious. Infectious means it is caused by a pathogen such as a virus or bacterium, and contagious means it can be transmitted directly or indirectly between people, often through droplets, airborne particles, or contact with contaminated materials. Smallpox is caused by a virus and spreads through close contact and respiratory droplets, making it both infectious and contagious. Plague can occur in a form that spreads between people via respiratory droplets (pneumonic plague), which also fits being infectious and contagious. Other options don’t fit as well. Noninfectious would mean no pathogen is involved, which isn’t true here. Noncommunicable means not spread from person to person, which isn’t accurate for the contagious forms of plague and smallpox. Zoonotic describes diseases primarily transmitted from animals to humans, which doesn’t capture the general behavior of these diseases across their typical human-to-human transmission routes.
