The Common Cold

The Common Cold
More than one hundred types of viruses are known to cause the common cold. This explains why scientific attempts to produce a vaccine have been so unsatisfactory. Over 40% of respiratory illnesses in children and adults arecaused by this family of organisms. Although colds occur throughout the year, there are peaks of incidence in the spring and fall. The disease is more severe in children, especially those under two years of age. Higher fevers,cough, croup, and occasionally pneumonia occur. Family infections are more often initiated by children. They spread like gossip in schools or any setting
where close contact is found.

After introducing the respiratory virus into the nose or throat, congestion,symptoms of discharge in the nose, general aching, and mild headache result.There is usually no fever. Nasal secretions increase over the period of a day or two. After a week or more, the individual has completely recovered. A number of factors predispose to the common cold, including unwise ingestion of a large amount of sugar, and exposure to sudden changes in temperature,particularly with chilling. Negative emotions are thought to be related to host susceptibility through a change in the acidity of the nasal mucous membrane.Such reactions as hatred, anger, fear and frustration bring about the temporary deficiency of lysozyme, a potent enzyme capable of killing many germs.

The treatment for a cold should include the general health measures for respiratory hygiene, utilizing copious intake of fluids, especially water, in-creased rest, steam inhalations, hot packs over the congested areas and the avoidance of close contact with other people who are susceptible to the same disease. Recovery is usually complete. Diet should be light with easily digested foods, especially fruit.
