Associate Safety Professional Practice Exam

Which of the following groups is most at risk for swimmers itch?

1. Beach content workers

2. Marine biologists

3. Gardeners

4. Freshwater workers and swimmers

The correct answer is: Freshwater workers and swimmers

Swimmer's itch, also known as cercarial dermatitis, is a skin rash that occurs as a result of exposure to certain parasites that are found in freshwater environments. These parasites, specifically flukes, are released by infected birds and can penetrate human skin, leading to an allergic reaction. The group that is most at risk for swimmer's itch is those who frequent freshwater bodies such as lakes and ponds. Freshwater workers and swimmers are directly exposed to these environments where the parasites live and reproduce. Their activities often involve prolonged contact with the water, increasing their likelihood of coming into contact with the offending parasites and developing the skin condition. In contrast, individuals in the other groups, such as beach workers and marine biologists, typically engage with saltwater environments, where swimmer's itch is not typically a concern. Gardeners, while they may interact with water, are less likely to have the same level of exposure to contaminated freshwater as swimmers or individuals who work directly in such environments. Hence, the focus on freshwater workers and swimmers accurately reflects the higher risk associated with those particular activities and environments.
