What disease can be contracted from a hot tub or spa?

The correct choice highlights the risks associated with Pseudomonas and Staphylococcus bacteria, which can indeed be contracted from hot tubs or spas. When water in these environments is not properly maintained, it can become a breeding ground for various bacteria.

Pseudomonas aeruginosa is known to thrive in warm, moist environments, making hot tubs an ideal habitat if the water is not treated correctly. This bacterium can cause skin infections, particularly in individuals with compromised immune systems, and can lead to conditions such as "hot tub folliculitis," which manifests as itchy, red bumps on the skin.

Staphylococcus aureus, another bacterium that can be found in inadequately sanitized hot tubs, can lead to skin infections or more severe health issues if the skin barrier is breached.

While other options such as Lyme disease, Legionnaires' disease, and Norovirus are relevant in other contexts, they are not typically associated with hot tub or spa use. Lyme disease is transmitted through tick bites, Legionnaires' disease is linked to aerosolized water, specifically from cooling towers, and Norovirus is primarily spread through contaminated food and surfaces or close contact with infected individuals. Thus, Pseudomonas and Staphylococcus are the primary
