Question

Infection of Entamoeba histolytica is prevented by

• A. Avoiding kissing
• B. Avoiding clothes of patient
• C. Uncontaminated food
• D. None of the above

Answer 1

The correct option is C Uncontaminated food

Ingestion of fecally contaminated food or water is the primary mode of transmission. Thus, reducing this contamination is the best method of prevention. Filtering or purifying drinking water (iodine or boiling) in endemic areas is important as is the washing of fruits and vegetables that may have been contaminated by the use of nightsoil as fertilizer. Improved sanitation will help to reduce the liklihood of transmission. Travelers to endemic areas can reduce the risk of infection by drinking bottled water, not using ice cubes in drinks, and washing fruits and vegetables with clean water.

So, the correct answer is 'Uncontaminated food'.
