Meningitis is brought on by viruses, bacteria, fungi, or parasites that cause infection of the protective membranes that are around the brain and spinal cord. Bacterial meningitis is a critical condition that spreads through respiratory secretions like saliva or mucus from an infected person, often transmitted through close contact such as coughing or kissing. Viral meningitis, more common than its bacterial counterpart, is typically caused by enteroviruses but can stem from other viral sources. Fungal or parasitic meningitis is rarer and primarily affects individuals with weakened immune systems. Timely medical intervention is crucial for bacterial meningitis, which can result in severe complications if not promptly treated and may be life-threatening. Vaccination plays a key role in preventing specific types of bacterial meningitis, emphasizing the importance of immunization in disease prevention.
