Explanation:

Worms impair the nutritional status of people they infect in multiple ways:

• Worms feed on host tissues, including blood, which leads to a loss of iron and protein and often contributes to anaemia.
• Worms can increase the malabsorption of nutrients; roundworm may compete for Vitamin A in the intestine.
• Some worms can cause a loss of appetite, reducing nutritional intake and physical fitness.
• Some worms can cause diarrhea and dysentery.
