Cold and cough are the most frequently reported symptoms to a doctor, especially when it comes to children. The conditions are so common that most don't even bother going to a doctor and consider this as part and parcel of their lives!
But the reason is simple- lowered resistance. Children especially have an underdeveloped immunity system, that is defective as far as resistance to common offending viruses are concerned. That is why they tend to fall prey to colds very easily. The problem comes when the immunity is still weak even as the child grows into an adolescent and then adult.
