**Question:** All of the following are milk-borne diseases except:

A. **Tuberculosis**
B. **Leprosy**
C. **Lyme Disease**
D. **Ebola Virus Disease**

**Core Concept:** Milk-borne diseases are infections caused by microorganisms that are transmitted through consumption of contaminated milk or dairy products. These diseases can result from the ingestion of pathogenic bacteria, viruses, or parasites.

**Why the Correct Answer is Right:**

D. Ebola Virus Disease is not a milk-borne disease. Ebola virus is transmitted through direct contact with the bodily fluids of infected individuals, as well as contact with contaminated surfaces or objects. While the virus can spread through human-to-human transmission, it does not primarily spread via milk consumption.

**Why Each Wrong Option is Incorrect:**

A. Tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis and is primarily transmitted through respiratory droplets from an infected person. While TB can occasionally be transmitted through contaminated food, including milk, it is not considered a common mode of transmission.

B. Leprosy (Hansen's Disease) is caused by Mycobacterium leprae and Mycobacterium lepromatosis. As with TB, leprosy is primarily transmitted through respiratory droplets and close contact with an infected person. Although milk consumption can contribute to the spread, it is not the primary mode of transmission.

C. Lyme Disease is caused by the bacterium Borrelia burgdorferi and is transmitted through tick bite, particularly from Ixodes ticks in the United States. While Lyme disease can be transmitted through consumption of infected dairy products, it is less common compared to other modes of transmission.

**Clinical Pearl:** While some milk-borne diseases exist (e.g., tuberculosis, leprosy, and Lyme disease), the correct answer D, Ebola virus disease, is not a milk-borne infection. Understanding the primary modes of transmission for each disease is essential for accurate diagnosis and treatment.
