Symptoms of latent tetanus

summary

Tetanus is generally caused by the wound infected with tetanus bacilli. Tetanus bacilli invade the human body wound, grow and reproduce, and produce toxins, which is an acute specific infection. It will take a period of incubation period before the onset of tetanus. Let's take a look at the symptoms of latent period of tetanus.

Symptoms of latent tetanus

If a person is infected with tetanus, he must have the following conditions: first, he must be deeply stabbed by something similar to a nail to form a closed wound and create a favorable environment for the reproduction of tetanus bacteria. Secondly, tetanus bacilli were found on the nails that stabbed the human body. Then, people who have been stabbed are not immune enough.

Incubation period: the length of incubation period varies, which is often related to factors such as whether they have received preventive injection or not, the nature and location of the wound, and the treatment of the wound. It is usually 7-8 days, but it is also short only 24 hours or as long as several months or years.

The most common symptom is jaw stiffness. Other symptoms include agitation, dysphagia, irritability, headache, fever, sore throat, shivering, muscle spasm, neck, arm and lower limb stiffness. As the disease progresses, the patient has difficulty opening his mouth. Facial muscle spasm produces a fixed smile on the face and eyebrow arch up. The muscles of the abdomen, neck and back are hard or spasmodic, causing the head and heel to pull backward, the body forward * arcuate, and the sphincter of lower sphincter spasm can lead to constipation and urinary retention.

matters needing attention

Tetanus toxoid is injected as antigen to make human body produce antibody for immune purpose. Basic immunization with toxoid usually requires three injections. 5ml was injected subcutaneously for the first time, then 0.5ml was injected every 4-6 weeks, and 0.5ml was injected 6-12 months after the second injection. These three injections are called basal injection. After that, 0.5ml of toxoid was injected subcutaneously every 5-7 years as intensive injection. The immunity was produced within 10 days after the first injection and reached the antibody concentration of effective protection after 30 days.
