Which preventive measure is recommended for pet rat owners to reduce hantavirus infection risk?

• A. Wash hands after handling rodents/bedding/cage
• B. Always keep windows closed when cleaning cages
• C. Feed the rats contaminated food
• D. Allow children to handle rodents unsupervised

Answer: (A)

Hand hygiene after handling rodents, bedding, or the cage is the most effective single step to lower hantavirus risk because the virus can be shed in rodent urine, droppings, and saliva and may contaminate hands and surfaces. Washing thoroughly removes the virus from your hands and reduces the chance of transferring it to your mouth, nose, eyes, or to objects you touch. In practice, this simple habit works well with good cage hygiene—damp-wiping droppings, disposing of waste properly, and using gloves when cleaning—but the core protective move is washing hands after any contact with the rats or their environment. Keeping windows closed is not the recommended approach for this purpose, and feeding contaminated food or letting children handle rodents unsupervised would increase exposure rather than reduce it.
