Poor handwashing by farmers may result in which of the following forms of disease transmission?

• A. Fecal-oral transmission
• B. Direct contact transmission
• C. Airborne transmission
• D. Vector-borne transmission

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the context of the problem, which involves poor handwashing by farmers. Consider how pathogens can be transferred from contaminated hands to a susceptible host.
2. Step 2: Recall that fecal-oral transmission occurs when pathogens in fecal matter are ingested, often due to contaminated hands or food. Poor handwashing can leave fecal pathogens on hands, leading to ingestion.
3. Step 3: Evaluate other transmission types: Direct contact transmission involves physical contact but not necessarily ingestion; Airborne transmission involves inhalation of droplets; Vector-borne transmission involves an insect or animal vector.
4. Step 4: Connect poor hand hygiene specifically to the ingestion route, which aligns with fecal-oral transmission, as contaminated hands can transfer pathogens to the mouth.
5. Step 5: Conclude that among the options, fecal-oral transmission best explains how poor handwashing by farmers can lead to disease spread.
