Noninfectious diseases are typically caused by what?

• A. Infectious diseases
• B. Fungal infections
• C. Viral infections
• D. Environmental conditions

Answer: (D)

Noninfectious diseases are illnesses not caused by living organisms invading the body. They usually come from factors in the environment, such as exposure to toxins or chemicals, physical stresses (like heat or radiation), poor nutrition, or genetic predispositions. In a pesticide work setting, environmental conditions such as exposure to pesticides or solvents, inadequate ventilation, extreme temperatures, or contaminated water can lead to health effects that are noninfectious. Infectious diseases, by contrast, come from pathogens like bacteria, viruses, or fungi, so they are not classified as noninfectious. Therefore, environmental conditions are the typical cause of noninfectious diseases.
