Forest encephalitis, also known as Soviet Spring-Summer Encephalitis or Far Eastern Encephalitis, is an acute central nervous system infectious disease caused by the forest encephalitis virus transmitted by hard ticks. Clinically, it often presents with sudden high fever, disorientation, headache, stiff neck, and may also involve functional disorders in the upper limbs and neck and scapular muscles. However, with timely symptomatic treatment, such as nursing care, temperature reduction, anticonvulsants, and treatment of respiratory failure, most patients can recover spontaneously and usually do not leave any post-infectious sequelae. Common treatment measures include the use of drugs such as vancomycin and ampicillin, as well as the implementation of serum therapy and high-potency immune gamma globulin treatment. During the treatment process, interferons, transfer factors, autoimmune ribonucleic acid, and ribonuclease may be used depending on the condition. In general, with appropriate symptomatic treatment, most encephalitis patients can recover completely without any concern for post-infectious sequelae. Wishing for a speedy recovery!
