Hypersensitivity is described as repeated minor exposure to many products.

• A. Acute exposure
• B. Tolerance
• C. Immunity
• D. Hypersensitivity results from repeated minor exposures

Answer: (D)

Hypersensitivity occurs when the immune system becomes sensitized after repeated low-level exposures to chemicals. With each exposure, the body’s defenses can overreact, so future encounters—even with small amounts or different products—trigger stronger reactions such as skin irritation or respiratory symptoms. In pest management, this is why gradual, repeated contact with various products can lead to hypersensitivity and underscores the importance of minimizing exposure and using protective equipment. Acute exposure describes a single or short-term high-dose event that causes immediate effects, not a sensitization-driven reaction. Tolerance means the body adapts to reduce its response with repeated exposure, which is the opposite of hypersensitivity. Immunity is protection against disease, not an adverse overreaction to a product. Hence hypersensitivity is described as the result of repeated minor exposures.
