What are the odds of tetanus infection?

Tetanus is an acute infectious disease caused by infected tetanus bacilli. Tetanus bacilli invade human body through skin or mucosal wounds, grow and reproduce in anoxic environment, and produce highly toxic spasmodic exotoxin-tetanus spasmodic toxin. The toxin invades human nervous system with blood flow and causes persistent or paroxysmal muscle spasms. The mortality rate of tetanus patients without treatment is very high. Tetanus infection depends on the location of the wound and the conditions of infection, that is, without the following conditions, it generally does not change tetanus. What is easy to get tetanus? 1. Wounds obviously contaminated by soil or dirt may be infected regardless of the size of the wound. 2. Severe open injuries, such as open brain injuries, open fractures, burns. 3. Fine and deep stab wounds. 4. Wounds not cleaned in time after injury. 5, outside the hospital emergency delivery or abortion, without further disinfection treatment. 6, the old trauma needs surgery, such as the need to implement foreign body removal or removal surgery. The above several situations are easy to cause tetanus probability is relatively large. So if not the above situation, the probability of infection tetanus is relatively low.
