Tetanus is an infectious disease that can be cured. Generally, tetanus is considered to be caused by the infection of Clostridium tetani, which produces toxins. Clinically, it is mainly characterized by muscle tension and rigidity, such as lockjaw, difficulty opening the mouth, risus sardonicus, stiff neck, and opisthotonos. In severe cases, it can involve the respiratory muscles and diaphragm, causing difficulty breathing, respiratory arrest, and even cardiac arrest. When patients with tetanus receive standardized and systematic hospital treatment, and if there are no severe complications, the vast majority of patients can be cured.

How to treat tetanus?

Generally speaking, a tetanus shot needs to be administered intramuscularly, but a skin test must be conducted before injection because tetanus vaccines can easily cause allergic reactions. The skin test usually involves a subcutaneous injection on the palm side of the forearm, followed by an observation period of 15 to 20 minutes. If there is no redness or itching, and the skin test is negative, then the vaccine can be administered intramuscularly, usually in the buttock. However, if the skin test is positive, as indicated by symptoms like redness, significant itching, or even systemic symptoms such as dizziness and cold sweats, it shows that the skin test for tetanus is positive. In this case, one can opt for a desensitization injection of diluted tetanus vaccine, followed by intramuscular injections four times, once every half hour, needing about two hours to complete.

How long should you avoid certain foods after getting a tetanus shot?

Tetanus antitoxin medication serves a preventative function and is commonly used as a vaccine. Receiving a tetanus shot is essentially aimed at preventing infections from the tetanus bacterium. Generally, there are dietary restrictions to follow after getting the shot. The effect of this medication typically lasts about a week, during which it is necessary to observe these dietary restrictions. It is usually advisable to avoid spicy or cold foods, such as chili peppers, beef, lamb, dog meat, or seafood. These should be eaten sparingly or avoided altogether. Otherwise, these spicy foods might directly affect the efficacy of the tetanus antitoxin. In such cases, the prevention of tetanus infections could be significantly reduced, thereby increasing the likelihood of contracting tetanus bacterium.

How long is a tetanus shot effective?

Tetanus generally refers to a specific type of infection caused by the entry of tetanus bacillus into the body through broken skin or mucous membranes, where it produces a large amount of toxin. Typically, the incubation period for tetanus is 6 to 7 days, but it can be as short as within 24 hours or as long as several months or even years. Therefore, if there is a wound, the first thing to do is to clean the wound with hydrogen peroxide or saline. Then, it is best to go to the hospital to get a tetanus vaccine within 24 hours. If the tetanus vaccine is not administered within 24 hours, it can still be effective if given within a week.

Tetanus incubation period

Tetanus is a specific infection caused by Clostridium tetani. The incubation period of tetanus is generally seven to eight days, but it can be as short as 24 hours or as long as several months to years. Patients with shorter incubation periods have a worse prognosis. Tetanus occurs within two weeks after injury in 90% of patients, presenting symptoms such as general weakness, headache, dizziness, chewing difficulty, local muscle tightness, painful pulling, and increased reflexes. Typical symptoms include muscle tonic contraction, opisthotonus, and facial expressions characterized by lockjaw and a sardonic smile.

How to avoid tetanus with minor wounds

If minor wounds are not properly handled, they can lead to serious problems, including tetanus. Treatment for minor wounds should be based on the integrity of the skin, the depth of the wound, and whether the object causing the wound was rusty. For simple minor wounds where the integrity of the skin is maintained and only abrasions are present, disinfection of the affected skin area may suffice. If the wound has compromised the integrity of the skin and is deep, especially if caused by rusty, sharp objects, it is necessary to thoroughly remove any foreign materials, clean the wound, and suture it. Dressing changes might be required, along with tetanus vaccination to prevent tetanus infection.
