The incubation period of tetanus varies from person to person, from as short as 24 hours to as long as several months, usually 7 to 8 days.
Tetanus is a specific infection caused by Clostridium tetani. In an anoxic environment, the bud cells of Clostridium tetani develop into proliferators, producing a large number of exotoxins, mainly spasmodic toxins, which are absorbed into the brain and spinal cord, bind to the synapses, inhibit the synapses from releasing inhibitory transmitters, and produce spasm of random muscles and sympathetic nerve excitation. The general incubation period is 7 to 8 days, the specific time varies from person to person, can be as short as 24 hours, the longest is several months.
People with deeper wounds at risk of tetanus infection should be treated promptly under medical supervision, with wound debridement, antitoxin and antibiotic application, symptomatic treatment, and timely tetanus vaccination.
