What causes newborn meningitis?

Newborn meningitis is primarily caused by bacterial infections, with the most common pathogens being Group B Streptococcus and Escherichia coli. Viral infections, such as those caused by herpes simplex virus or enteroviruses, can also lead to meningitis in newborns. Transmission typically occurs during delivery, especially if the mother is a carrier of the bacteria, or through exposure to infected fluids. Early recognition and treatment are crucial to prevent serious complications.
