Hot weather, more mosquitoes, pay attention to the prevention and treatment of encephalitis B. Epidemic B encephalitis, referred to as B encephalitis, is caused by the B encephalitis virus, the brain parenchymal inflammation as the main lesion of the central nervous system acute infectious disease. The mosquito is the main vector, so mainly in the summer and autumn epidemic, the disease has a high death rate. B encephalitis is a zoonotic disease of natural origin, poultry, livestock can be infected with the virus and become the source of infection, pigs are the most important source of infection of the disease. Experts and scholars have found that the disease spreads among pigs before it becomes prevalent in the population, and that children and adolescents are the main incidence group of BSE, especially children between the ages of 3 and 6 years old are the most susceptible. Therefore, vaccination of children is very useful to prevent BSE. Adolescents and adults can also be infected. The main clinical manifestations of BSE are high fever, impaired consciousness, convulsions and signs of meningeal irritation. After a person is bitten by a mosquito with the BSE virus, most people develop only an insidious infection, without neurological symptoms, and the majority of adults are thus immune. A small number of people by this mosquito bite about 10 to 14 days after the onset of symptoms vary in severity. The onset is generally rapid, with a temperature of 39 to 40 degrees Celsius within 1 to 2 days, accompanied by headache, violent vomiting, drowsiness or lethargy, etc. After 2 to 3 days, the disease worsens significantly, often appearing coma, restlessness, talking nonsense, irregular breathing, etc., may also appear neck tonic, convulsions. The critical stage of the disease is characterized by high fever, marked drowsiness, significant disturbance of consciousness, convulsions, loss of superficial reflexes, and limb spasms; death may also occur due to high fever, cerebral edema, and respiratory or circulatory failure. Some patients have very mild symptoms, with only headache and low fever, and return to full normalcy within a few days. In most patients, the fever gradually subsides and other symptoms disappear within 7 to 10 days after the onset of the disease. A few severe patients may have sequelae such as mental abnormalities of varying length, mental retardation, aphasia, and inability to move their arms and legs due to convulsions and coma lasting longer, and remaining after recovery. The key to getting BSE is early diagnosis and treatment. In the epidemic season of BSE, if you encounter a patient with an acute onset of fever, headache, drowsiness, no or only mild cough, sore throat, runny nose and other symptoms, you should suspect “BSE”. Especially on the first and second day of illness, in addition to fever, some mild mental symptoms such as drowsiness, vomiting, nausea, irritability and double vision will appear. For the treatment of BSE, as long as early diagnosis is made and a combination of Chinese and Western medicine is taken in a timely manner, such as symptomatic treatment to lower body temperature, stop spasms and prevent respiratory failure, the cure rate can be greatly improved and sequelae avoided. Brain B is completely preventable. The following preventive measures can be taken: 1, good anti-mosquito, mosquito control measures are the main measures to prevent and control the disease. 2, children under 10 years of age should be injected with “inactivated B encephalitis vaccine”. 3, taking some Chinese medicine can also prevent “B brain” and other heat illnesses, such as the use of Banlangen 15 grams, Guanzhong 15 grams, wild chrysanthemum 10 grams, licorice 5 grams, water decoction, 3 doses per week, it has a good preventive effect.
