multiple choice

• endogenous infection
• incurable infection
• bacterial infection
• healthcare-associated infection
• exogenous infection

Explanation:

Analyze the clinical scenario

The scenario describes Max coming home with chickenpox, which is caused by the varicella-zoster virus. The pediatrician asks if other children at his daycare also have it. This indicates that the pathogen was transmitted to Max from an external source (another child at the daycare) rather than originating from within his own body's normal flora.

Define the types of infections

To determine the correct classification, let's evaluate the medical terms:

• Exogenous infection: An infection caused by a pathogen that enters the body from the outside environment or another person (e.g., catching chickenpox at daycare).
• Endogenous infection: An infection caused by an infectious agent already present in or on the body, such as normal microflora that becomes pathogenic due to opportunistic conditions (e.g., shingles, which is a reactivation of the latent varicella virus already inside the body).
• Healthcare-associated infection (HAI): An infection acquired in a healthcare facility. Daycare is not a healthcare facility.
• Bacterial infection: Chickenpox is caused by a virus, not bacteria.

Connect to the correct term

Using the Infectious Disease Terms knowledge point, since Max contracted the virus from an external source (the daycare environment or another child), this is classified as an exogenous infection.

Answer:

• endogenous infection
• incurable infection
• bacterial infection
• healthcare-associated infection
• exogenous infection (Correct answer)
