Which group has the highest incidence of salmonellosis?

Which group has the highest incidence of salmonellosis?

• A. Infants and young children.
• B. Healthy adults.
• C. Elderly.
• D. Teenagers.

Answer: (A)

Infections with Salmonella are most common in the youngest age group because their bodies are still developing defenses and because their daily behaviors increase exposure. Infants and young children are more likely to put objects in their mouths, have close contact in daycare, and touch surfaces that may be contaminated, making it easier for them to ingest the bacteria. Their immune systems aren’t fully mature yet, and some have lower gastric acidity, which provides less of a barrier to infection when contaminated foods or animals are involved. While healthy adults typically have stronger defenses and lower exposure, and the elderly may be at higher risk for severe disease rather than the highest incidence, young children bear the greatest burden of infection.
