Tetanus wounds will scab over, but whether or not they do is not related to tetanus. The process of scabbing occurs with any wound and may be very slow, but it does not affect its healing. Tetanus is mainly caused by puncture wounds from nails, glass or other sharp objects that are deep in length. Clostridium tetani invades the body through the wound to produce a toxin, which multiplies in an anoxic environment and can cause specific symptoms such as muscle tissue spasms. Its incubation period after infection is usually about a week, but some patients develop the disease within 24 hours or the virus incubates for months and years. Localized scabs have no effect on whether or not you are infected with tetanus, and it is important to clean and care for the injury to keep the area dry. Infection with the tetanus virus is associated with a high mortality rate among the injured. Prevention should be more important than treatment by receiving tetanus vaccinations and treating wounds properly after injury.
