Last spring my girlfriend and I were constructing large tomato cages by bending metal fencing into a circle then securing it with wire and snipping off the excess fencing. The fencing wasn’t cooperating and both of us sustained a number of scratches from the rusty metal. Jokingly we started talking with our jaws clenched as if we had lockjaw. After we had made a few cages and called it a day, I was washing my wounds and wondering when I last had a tetanus booster. Not knowing how current I was, I “googled” tetanus to see if I was actually in imminent danger of having to eat everything through a straw. This is what I discovered.
Tetanus is a serious infection. It is caused by the bacteria
Clostridium tetani which can be found almost everywhere in the natural environment. If the bacteria gets into the body it can produce a toxin that can spread systematically throughout the body and interfere with the central nervous system, producing muscle stiffness, spasms, or rigidity and the infamous locked jaw. Tetanus is potentially fatal. Without treatment, one out of four infected people die. Yikes! Tetanus has a mortality rate of 25% in the U.S. and 50% worldwide. There are currently no blood tests that can be used to diagnose tetanus. The diagnosis is based on the presence of tetanus symptoms. If you are infected, it can take a while for the symptoms to present themselves; anywhere from eight days to a few months. It basically depends on how far from the central nervous system the toxin entered the body.
