Tetanus – Its Causes and Treatment
Saturday, May 23rd, 2009What causes tetanus? Is it a serious disease? Why do doctors insist on jabbing everyone who has a cut with a tetanus shot?
A bacteria called Clostridium tetani can live quite harmlessly in the gut of many animals, particularly horses. When it passes out of their bodies in faeces it forms a hard microscopic cyst which then contaminates the soil and waits for a chance to return to active life. The bacteria can remain inactive for many years until it enters a cut or wound in the dirt of dust that may be around when the tissues are exposed.
Once it has infected a cut, it starts multiplying and produces a chemical which is absorbed into the bloodstream and spreads throughout the body. This chemical (a toxin) attacks the small muscles used for chewing our food, making it difficult to open the mouth. Thus the common name for tetanus is lockjaw. The toxin gradually attacks larger and larger muscles, irritating them and causing them to go into severe spasm.
These spasms are similar to the cramps you may experience in your leg at night, except they are more severe and can attack every muscle in your body. The patient remains conscious throughout the disease, but eventually the muscles which control breathing and the heart are affected, and the patient dies.
There are very few effective treatments for tetanus, because although the bacteria may be killed, the toxin remains in the body. Tetanus can be prevented by vaccination, but it cannot be cured.
Should an adult man have a mumps vaccine if he has never had the disease?
Yes. Children should have a mumps vaccine at one and five years of age, so it is now an uncommon condition, but if an adult catches the disease, it is usually more severe than in a child.
If an adult (man or woman) has not had mumps, a vaccine that has minimal side effects is available to give life-long protection. Most general practitioners would carry a supply of this vaccine, and so it is a very simple matter to obtain protection.
Mumps seems to have the unfortunate ability to strike just before your annual holidays or at some other vital time, so for this reason alone it is worthwhile being protected. In addition, the testes of men and ovaries of women may be affected by a severe case of mumps. This complication is not common, but may lead to sterility in both men and women.
