Which two diseases are commonly of concern as zoonotic risks in field operations?

• A. Rabies and ringworm
• B. Leptospirosis and yersiniosis
• C. Canine parvovirus and distemper
• D. Rabies and leptospirosis

Answer: (D)

In field work, the main concern is diseases that can jump from animals or contaminated environments to humans. Rabies stands out because it spreads through bites or contact with infected saliva and is almost always fatal without timely treatment, making it a critical biohazard to guard against in the field. Leptospirosis is another major risk, acquired when people contact water or soil contaminated with urine from infected animals; it can range from a mild illness to a serious, life-threatening infection, so protective gear and good hygiene are essential in environments where exposure to animal waste or contaminated water is possible. Together, these two cover the strongest, most commonly encountered zoonotic threats in field operations, which is why they’re the best match. The other options mix in diseases that aren’t typically transmitted to humans in field settings (canine parvovirus and distemper mainly affect dogs), or include infections that are less common or less directly relevant to field exposure (ringworm is zoonotic but generally less central as a field risk; yersiniosis is possible but not as prominent a concern as leptospirosis).
