Which condition is described as unusual myiasis or acariasis?

• A. Acute coughing
• B. Mild fever
• C. Unusual myiasis or acariasis
• D. Chronic weight gain

Answer: (C)

This item centers on recognizing infestations by parasites described as unusual myiasis or acariasis. Myiasis is infestation by fly larvae, while acariasis is infestation by mites. When such infestations occur in an atypical way—unusual species, unusual body sites, or in a person or location where they’re not expected—the description used is “unusual myiasis or acariasis.” That phrasing directly identifies the condition being described, which is why it’s the best answer. The other options point to generic symptoms like coughing or fever, or to weight gain, none of which define infestations by larvae or mites. In surveillance terms, spotting an unusual myiasis or acariasis signals the need for investigation to understand exposure, sources, and potential public health implications.
