Which sign is commonly observed with diarrhea in nonhuman primates?

• A. Dehydration
• B. Vomiting
• C. Increase in activity
• D. Overabundant salivation

Answer: (A)

Fluid loss from diarrhea commonly causes dehydration in nonhuman primates, making dehydration the most reliable sign to watch for. You’ll see dry mucous membranes, reduced skin turgor (poor elasticity), and often sunken eyes, with possible lethargy as the body's fluids diminish. Vomiting isn’t typically a primary sign of diarrhea in these animals, an increase in activity would be unusual during illness, and overabundant salivation isn’t a common feature of diarrheal illness in nonhuman primates. Recognizing dehydration early helps guide prompt fluid therapy and supportive care.
