Leptospirosis is commonly transmitted through which route?

• A. The urine of infected animals.
• B. Ingestion of contaminated food or water.
• C. Direct contact with blood.
• D. Touching contaminated soil.

Answer: (B)

Leptospira are shed in the urine of infected animals and contaminate the environment, especially water sources. The bacteria then enter a new host when contaminated water or food is swallowed, or when oral or mucous membranes come into contact with contaminated material. This ingestion route is a common and straightforward way exposure occurs in wildlife and human settings, making it the best answer in this context. Direct blood contact is not how Leptospira typically spreads, and merely touching soil won’t cause infection unless the organism can access mucous membranes or a break in the skin; citing ingestion emphasizes the real-world exposure pathway through contaminated water or food.
