Tetanus
|
Tetanus is a now uncommon illness since most children are vaccinated with the tetanus vaccine (as part of the DTaP vaccine) and adults receive regular booster doses every ten years (Td vaccine). Tetanus is caused by the Clostridium tetani bacteria that usually gains access to a person through a wound. It then grows and can cause serious muscle and nerve problems. Symptoms can include muscle spasms that lead to stiffness of the jaw, drooling, difficulty swallowing. The spasms gradually spread to other muscles throughout the body.
Tetanus is very difficult to treat and is best prevented by routine vaccination. Children usually receive four doses of tetanus as part of the DTaP vaccine and then a booster at four years of age and again when they are twelve. Adults require boosters every ten years. You should see a doctor for treatment and to receive a booster if you receive a wound and have not had a tetanus shot in the last five years, especially if the wound is at all contaminated with dirt, soil, feces, or saliva, and if it is a puncture wound or crush wound. Minor wounds that are clean may not need a tetanus booster if your immunizations are up to date.
