Why do some children fall ill more frequently than others living in the same locality?

उत्तर
The frequency of falling ill depends on the strength of the body’s immune system to fight against pathogenic microbes. Some children fall ill frequently due to their poorly developed immune systems. Adequate nutrition and exercise are required for the development of a strong immune system.
