Question

Which among the following diseases is non-infectious in origin:

• A. Rabies
• B. Listeriosis
• C. Trichomoniasis
• D. Milk fever

Hint:

"Fever" in a disease name doesn't always mean infection. Milk fever is a classic example of a metabolic disease caused by a mineral imbalance, not a germ.

Answer 1

The Correct Option is D

Milk fever, or parturient paresis, is a metabolic disorder, not an infectious disease. It is caused by a temporary low level of calcium in the blood (hypocalcemia) that occurs around the time of calving in dairy cows. Rabies (viral), Listeriosis (bacterial), and Trichomoniasis (protozoal) are all infectious diseases caused by specific pathogens.
