Question: 1 / 320

In an outbreak of pneumonia caused by Legionella, where should you prioritize checking for the source of bacteria?

Food handlers for infected cuts and sores

For dead animals on the property

Hot tubs, showers, and fountains and the water sources that supply them

In the context of an outbreak of pneumonia caused by Legionella, it is crucial to prioritize checking locations and water sources where Legionella bacteria are commonly found. The correct answer focuses on hot tubs, showers, fountains, and the water sources that supply them because these environments can facilitate the growth and aerosolization of Legionella, which is typically transmitted through inhalation of contaminated water droplets.

Legionella thrives in warm water conditions, making hot tubs and similar fixtures prime suspects in outbreak investigations. These systems can become breeding grounds for the bacteria, especially if the water is not properly maintained or treated. Therefore, investigating these areas is critical to identifying and controlling the outbreak, as well as preventing future cases.

In contrast, while food handlers or sick employees might pose a risk for other types of infections or outbreaks, they are not directly related to the transmission of Legionella. Checking supplies contaminated by dead animals is also less relevant for this type of pneumonia, as Legionella is generally not transmitted from animals. This highlights the need for focused investigations in certain environments where the conditions support the growth of the organism responsible for the outbreak.
