Cold is caused by hundreds of viruses and by allergy. Hence it is common. Apart from the inconvenience it causes, it is not really harmful. It is a self-limited illness that lasts for about 3-5 days. Since it is self-limiting, cold does not need any trearment. Antibiotics are of no use. Steam-inhalation may help. If the child had nose block, nasal saline drops may be used. If the child has allergy, antihistamines may be required. These medications should be taken only on the advice of your doctor. Avoiding exposure to dust, pollen, pollution, etc, can prevent cold occuring due to allergy. Other types of cold cannot be prevented.
