The main clinical symptoms of pseudorabies are sudden behavioral abnormalities, itching of the head and limbs, muscle spasms throughout the body, and foaming at the mouth and runny nose in some patients. It is an infectious disease caused by pseudorabies virus. Both humans and animals can be infected, and generally this virus is found in dogs, wolves, cats and other carnivores, and is usually caused by the bite of an animal infected with the pseudorabies virus. The patient then develops tremors, uncoordinated movements, drooling, stiff neck muscles, and an elevated body temperature. In conclusion, once infected with pseudorabies virus, patients are advised to take appropriate treatment measures promptly. At present, there is no effective anti-virus drug in the clinic, and only symptomatic treatment can alleviate the condition. Therefore, when the patient has the above symptoms, he/she should consult a doctor in time and receive proper treatment under the guidance of a professional doctor.
