Patients with encephalitis who are in a coma need to be judged according to the site and severity of their inflammation to determine when they will awaken, and some patients even remain in a coma and cannot be awakened. Because of the current medical conditions, most patients will awaken after 7-20 days of coma, therefore, patients should be detected and treated early to reduce the damage caused by inflammation. The incidence of encephalitis is now lower in Guangdong Province and higher in Fujian and Sichuan. Since the human body’s resistance is poor in summer, if infected with the virus due to improper diet, it can cause diarrhea; there are more mosquitoes in summer, and the virus can be transmitted through mosquito bites, so summer is the season of encephalitis.
