Tetanus is mainly induced by the infection of the body with tetanus bacilli and is an acute specific infectious disease. The early symptoms of tetanus vary depending on the age and physical condition of the patient, and cannot be generalized. If an adult develops tetanus infection, early respiratory and neurological discomfort may occur, while if a newborn develops the infection, there may be prominent manifestations of external abnormalities.1. Adults: Patients with firearm wounds, blind tube trauma, burns and other traumatic injuries are prone to tetanus bacilli entering the wound and thus triggering infection when disinfection and anti-inflammatory treatment is not done in a timely manner. In the prodromal phase of the disease, the patient may experience discomfort such as weakness, headache, muscle aches or spasms, along with abnormal motor symptoms such as clenching of teeth and tonicity of the neck muscles. Within a few hours, muscle spasms may spread, such as a “bitter smile” with the lips of the face being drawn together and the limbs showing muscle tonicity and slight corkscrewing. In addition, there are typical manifestations such as respiratory spasms, sputum production, airway obstruction, irritability, and irritability. 2. Newborns: mainly caused by infection of the umbilical cord, early clinical symptoms include difficulty sucking milk, and abnormalities in appearance such as forehead wrinkling, eye closure, and lip retraction. In addition, the child may also experience discomfort such as muscle tonicity of the limbs and corns, similar to that of adults, but to a lesser extent than adults, and some children with severe cases may suffer from asphyxia.
