Pseudorabies will mainly present with sudden abnormal behavior, muscle spasms, itching of the head and limbs, pharyngeal paralysis, and salivation. Pseudorabies is an infectious disease caused primarily by the pseudorabies virus. Typical clinical symptoms are sudden abnormal behavior, muscle spasms, head and limb itching, pharyngeal paralysis, and salivation. It is an acute infectious disease and as such has a rapid onset with a high mortality rate usually within 48 hours of the onset of symptoms. The disease also has a certain incubation period. Early on, it may present as generalized weakness, lethargy, and irritability. As the disease progresses, severe clinical symptoms may develop. Once infected with this disease, treatment is required; there are no specific antiviral drugs available, and only symptomatic supportive treatment is available; if necessary, tracheal intubation should be performed to protect the airway. Symptoms of pseudorabies should be treated in a timely manner in a hospital under the guidance of a medical professional.
