Tetanus can be contracted when a wound is deprived of oxygen and infected with Clostridium tetani.
The causative agent of tetanus is Clostridium tetani, a specialized anaerobic bacterium, gram-positive, usually present in the intestinal tract of humans and animals, excreted with feces, distributed in nature in the form of spores, especially in the soil.
Traumatic wound tetanus contamination rate is very high, but the incidence rate is not high, the onset of the disease must have an anoxic environment, if the wound is deep, and the outer mouth is small, and at the same time there is aerobic bacterial infection, consuming the oxygen in the wound, the formation of an anaerobic environment suitable for the growth and reproduction of Clostridium tetani, there is a possibility of tetanus infection.
If the wound is deep and the external opening is reduced after the injury, it is necessary to go to the hospital for consultation and treatment in time to avoid delaying the condition.
