Mucus swelling is a nightmare for parents of children from newborn to school age. It is mainly caused by weakened immunity, poor hygiene, change in weather and vitamin deficiency. The viruses that cause rhinitis are highly infectious. They are spread by droplet infection during sneezing and coughing, by shaking hands or using an infected towel, touching a door handle or a toy.
