In low-income countries, children can get infected with worms soon after they stop breastfeeding and may face reinfection throughout their lives. Worm infections rarely cause immediate harm but often lead to chronic conditions, negatively affecting a child’s health, nutrition, learning ability, and overall development.

Typically, children over 2 years old should undergo deworming every 6 months. For children under 2 years old, worm infections can cause poor appetite, slow growth, and malnutrition. Therefore, it is necessary to take them to a medical facility for screening and appropriate intervention.
