The main causative agent of purulent meningitis in children is Neisseria meningitidis. Treatment requires timely administration of antibiotics, while prevention can be achieved through vaccination and enhanced hygiene management. Neisseria meningitidis is transmitted through the respiratory tract. After infection, the bacteria invade the meninges, causing inflammation. Early symptoms include fever, headache, vomiting, and neck stiffness. In severe cases, it can lead to coma or death.

1. Neisseria meningitidis is the main pathogen causing purulent meningitis in children. It is transmitted through droplets; infected individuals release the pathogen when they cough or sneeze, and healthy children may become infected after inhaling the droplets. After entering the bloodstream, the bacteria cross the blood-brain barrier, causing inflammation of the meninges. This bacterium is highly infectious, especially in crowded places with many children, such as kindergartens and schools, where it spreads easily.

2. Antibiotic treatment is the first-line treatment for meningococcal infections. Commonly used drugs include penicillin, ceftriaxone, and chloramphenicol. Penicillin works by inhibiting bacterial cell wall synthesis, ceftriaxone is highly effective against resistant strains, and chloramphenicol is used for patients allergic to the former two. Treatment needs to be adjusted according to the results of drug sensitivity testing, and the course of treatment is usually 7-14 days.

3. The key to preventing meningococcal infection is vaccination. Currently, there are conjugate vaccines for meningococcal groups A, C, W, and Y, and a meningococcal vaccine for group B. Vaccination can significantly reduce the risk of infection, and children are advised to be vaccinated according to the national immunization program. Maintaining good hygiene habits, such as frequent handwashing and avoiding close contact with infected individuals, can also effectively prevent infection.

4. Early identification and treatment are crucial. Parents should pay attention to whether their children develop symptoms such as fever, headache, vomiting, and stiff neck. If meningitis is suspected, seek medical attention immediately. Doctors will obtain cerebrospinal fluid through lumbar puncture for bacterial culture and drug sensitivity testing. After diagnosis, antibiotic treatment will begin as soon as possible, while closely monitoring vital signs to prevent complications such as cerebral edema and shock.

Purulent meningitis in children is caused by Neisseria meningitidis. Timely treatment with antibiotics and vaccination are key to prevention and treatment. Parents should be vigilant and seek medical attention immediately if they notice any suspected symptoms to avoid delaying treatment and causing serious consequences.
