Question 6 • NY-Life Science: BiologyTerm 2 Hillcrest

Two patients were admitted to the hospital. Patient one was diagnosed with salmonella poisoning, and patient two had West Nile. Which best describes their sicknesses?

Answer

Patient one has a communicable disease and patient two has a noncommunicable disease.

Patient one has a noncommunicable disease and patient two has a communicable disease.

Patient one contracted the sickness from contaminated materials and patient two contracted the sickness from an animal vector.

Patient one contracted the sickness from an animal vector and patient two contracted the sickness from contaminated materials.

Explanation

Salmonella poisoning is commonly acquired by eating food contaminated with Salmonella bacteria, so patient one contracted the sickness from contaminated materials. West Nile virus is typically transmitted to people through the bite of an infected mosquito, which is an animal vector. Therefore, choice C best describes how each patient contracted the sickness.
