New Delhi, October 6 (Daily Kiran) : Meningitis is an infection or inflammation of the membranes covering the brain and spinal cord. This condition can affect individuals of any age and can escalate quickly in severity. According to the World Health Organization (WHO), bacterial meningitis is particularly concerning.
The causes of meningitis are varied, including bacteria, viruses, fungi, and certain parasites. Key bacterial causes include meningococcal, pneumococcal, Haemophilus influenzae, and group B streptococcus. The risk of specific pathogens varies with age, immune status, and exposure to infections. For instance, group B streptococcus poses a higher risk to newborns, while meningococcal, pneumococcal, and Haemophilus influenzae are significant concerns for children and teenagers.
Recognizing the symptoms of meningitis is crucial. WHO identifies common symptoms such as high fever, headache, stiff neck, vomiting, sensitivity to light, and changes in mental status. In severe cases, symptoms can escalate to seizures, loss of consciousness, or weakness in limbs. However, not every patient will exhibit all symptoms simultaneously.
In infants, meningitis symptoms may differ slightly. Affected babies may be less active, difficult to awaken, irritable, may struggle to feed, or cry with a weak voice. In some instances, the soft spot on the top of the head, known as the fontanel, may bulge. Such symptoms should not be overlooked.
The spread of meningitis depends on its cause. Many bacteria can be present in the nose and throat and may transmit from person to person through respiratory droplets or throat secretions. The risk of transmission increases in crowded settings or prolonged close contact.
Vaccination is the most effective way to protect against some common bacterial causes of meningitis. Vaccines are available for meningococcal, pneumococcal, and Haemophilus influenzae. Additionally, maintaining regular hand hygiene and avoiding close contact with infected individuals, as well as not sharing personal items like cups or toothbrushes, is essential. In cases of close contact with someone infected with meningococcal meningitis, doctors may recommend preventive antibiotics.
Most importantly, meningitis is considered a medical emergency. If symptoms like high fever, stiff neck, severe headache, confusion, persistent vomiting, seizures, or rapidly deteriorating condition appear, immediate medical assistance is necessary. Delaying treatment for bacterial meningitis can worsen the situation significantly.
