Which route is typical for Salmonella transmission from mice to humans?

• A. Inhalation of aerosols
• B. Fecal-oral route
• C. Direct skin contact
• D. Bloodborne transfer

Answer: (B)

The main concept is how Salmonella moves from mice to humans, which is primarily through the fecal-oral route. Salmonella is shed in mouse feces, so contamination tends to occur when people handle mice, cages, bedding, or litter and then touch their mouths or prepare food without washing hands. Ingesting even small amounts of material contaminated with the bacteria can lead to infection, making sanitation and hand hygiene critical in settings with mice.

Inhalation of aerosols can occur if fecal material is disturbed and becomes airborne, but this is not the typical route for Salmonella transmission from mice to humans. Direct skin contact could pose a risk if there are open wounds and contaminated material, but again, ingestion remains the main pathway. Bloodborne transfer is not a characteristic route for Salmonella infection from mice to humans.
