How is meningitis caused in infants?

Infant meningitis is caused by a variety of reasons, such as bacterial infection, viral infection, fungal infection, other reasons, etc. 1. Bacterial infection This is one of the important causes of infant meningitis. Common pathogens such as meningococcus, Streptococcus pneumoniae, Haemophilus influenzae, etc. When the immunity of infants is low, these bacteria can enter the meninges through blood transmission or direct spread, causing inflammation. For example, infants may be infected with other parts of the body, such as pneumonia, sepsis, etc., bacteria into the blood and then invade the meninges. 2. Virus infection A variety of viruses can also cause meningitis in infants, such as enterovirus, herpes simplex virus, etc. Infants are at increased risk of meningitis, especially during some viral seasons. 3. Fungal infection Under certain circumstances, such as infants with immune deficiency or long-term use of broad-spectrum antibiotics, fungal meningitis can occur. Common fungi include Candida. These fungi can colonize the body and invade the meninges under appropriate conditions. 4. Other causes include congenital abnormalities, such as meningoencephalocele, which allows brain tissue to communicate with the outside world and increases the chance of infection. Infants with meningitis are often more dangerous, and if not treated in time, can lead to serious neurological sequelae and even life-threatening. Therefore, for infants with fever, irritability, lethargy, vomiting and other abnormal performance, parents should attach great importance to timely medical diagnosis and treatment, in order to reduce the occurrence of adverse consequences. At the same time, active prevention of infection, enhance infant immunity and other measures to reduce the incidence of meningitis is also important.
