According to the CDC WeChat official account, the early symptoms of epidemic cerebrospinal meningitis are very similar to the common upper respiratory tract infection, which can easily be ignored. If you or your family members experience flu like symptoms such as fever, headache, and fatigue, don't take it lightly - this may not be a common cold, but an early symptom of meningitis. Cerebrospinal meningitis, also known as epidemic meningitis, is an acute respiratory infectious disease caused by Neisseria meningitidis. It has a rapid onset and progression, like a hidden "assassin". Delaying treatment may increase the risk of severe illness and death. Although meningitis is dangerous, it can be prevented and controlled. What are the characteristics of meningitis? Incubation period of 1 to 7 days: Some people may have no symptoms after infection, but they can still transmit it to others. Rapid onset and progression: sudden high fever, severe headache, frequent vomiting; Skin bruising, ecchymoses, and even life-threatening conditions may appear within a few hours. Severe sequelae: About 10% to 20% of survivors may suffer permanent damage such as hearing loss and nerve damage. Who are more likely to be targeted? Students and collective living groups are prone to spread in densely populated places such as dormitories, classrooms, and factories. Infants and adolescents under the age of 1 are at high risk of developing meningitis. Individuals with weakened immunity, such as those with certain immune related diseases. Travelers to high-risk areas for disease outbreaks, such as those visiting countries in the African "meningitis belt" or those participating in pilgrimage. Three lines of defense, building a strong health barrier. First, vaccination is the most effective. Getting vaccinated against meningitis is the most powerful weapon for preventing it. China has included Group A and Group C meningococcal vaccines in the national immunization plan and provided free vaccination for children. In addition, there are self funded meningococcal vaccines containing ACWY groups available for selection. Secondly, cultivate good hygiene habits. Wash hands frequently, ventilate frequently, and open windows at least 3 times a day for no less than 10 minutes each time. Go to crowded and poorly ventilated places during the popular season. The third is to detect and seek medical attention early. If you experience the following symptoms, please seek medical attention immediately: sudden high fever, severe headache, jet vomiting, mental fatigue, and skin bruising and spots. Special reminder: If the symptoms of a "cold" are severe, or accompanied by worsening headaches and deteriorating mental state, do not force yourself. Seeking medical attention as soon as possible is key. (New Society)
