What is Bacterial Meningitis?

Bacterial meningitis is a severe and potentially life-threatening infection that causes the inflammation of the protective membranes covering the brain and spinal cord, known as the meninges. This medical emergency requires prompt diagnosis and treatment to prevent serious health complications.

Causes of Bacterial Meningitis

Bacterial meningitis is primarily caused by pathogenic bacteria that enter the bloodstream and migrate to the brain and spinal cord, though there can be direct routes of infection through a severe head trauma, surgery, or contiguous spread from adjacent infections such as sinusitis or otitis media.

Common Bacteria Responsible for Meningitis

Several types of bacteria can cause meningitis, the most common in the UK being Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae. Each of these bacteria can lead to outbreaks in different age groups and settings.

Neisseria meningitidis (Meningococcal Meningitis)

Neisseria meningitidis, commonly known as meningococcus, is one of the leading causes of bacterial meningitis. It is particularly known for causing outbreaks in young adults, especially in settings such as universities. It is spread through respiratory droplets and requires close contact for transmission.

Streptococcus pneumoniae (Pneumococcal Meningitis)

Streptococcus pneumoniae is another significant cause of bacterial meningitis, particularly in infants and older adults. This bacterium commonly exists in the respiratory tract, and infections can follow from complications of pneumococcal pneumonia, ear infections, or sinusitis.

Haemophilus influenzae Type B (Hib)

Previously a common cause of meningitis in children under five in the UK, Hib infections have dramatically decreased since the introduction of the widespread vaccination programme. Despite being less common now, it remains a possible cause for unvaccinated individuals or in regions where vaccination rates are lower.

Risk Factors

Several factors can increase the likelihood of developing bacterial meningitis. Young age, especially infants, is at higher risk due to underdeveloped immune systems. Group settings, travel to countries with higher rates of meningococcal disease, and immunocompromised states also elevate the risk. Additionally, individuals with no spleen or a compromised immune system are more vulnerable.

Prevention Measures

Vaccination remains the most effective prevention strategy against bacterial meningitis. Vaccines are available for the major bacterial strains causing meningitis, including the meningococcal, pneumococcal, and Hib vaccines. Maintaining up-to-date immunisations and practicing good hygiene, particularly handwashing and covering the mouth when coughing or sneezing, play crucial roles in prevention.

What is Bacterial Meningitis?

Bacterial meningitis is a serious illness. It happens when the coverings around the brain and spine get swollen. These coverings are called the meninges. If you have this illness, you need to see a doctor quickly to get treatment. This helps to stop bad health problems.

Causes of Bacterial Meningitis

This illness is mostly caused by bad germs called bacteria. These bacteria can get into your blood and then reach your brain and spine. Sometimes, it can also happen after a bad bump on the head, surgery, or from nearby infections like ear or sinus infections.

Common Bacteria That Cause Meningitis

There are different bacteria that can cause meningitis. In the UK, the most common ones are Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae. Different germs can cause the illness in different people and places.

Neisseria meningitidis (Meningococcal Meningitis)

Neisseria meningitidis is also called meningococcus. It often causes meningitis in teenagers and young adults. This happens a lot where lots of people are together, like at universities. It spreads through tiny drops from coughs or sneezes, so you need to be close to someone to catch it.

Streptococcus pneumoniae (Pneumococcal Meningitis)

Streptococcus pneumoniae is another germ that causes meningitis, especially in babies and older people. This germ lives in the nose and throat. It can cause infections after problems like pneumonia, ear infections, or sinus infections.

Haemophilus influenzae Type B (Hib)

Before, Hib affected many young children in the UK. But now, because of vaccines, it happens much less often. Children who have not been vaccinated or live in places with fewer vaccines can still get it.

Risk Factors

Some things make it more likely to get bacterial meningitis. Babies are more at risk because their bodies are still growing strong defenses. Being in places with lots of people, traveling to countries with more meningitis, or having a weak immune system can also be risks. People without a spleen or with weak health defenses can get sick easier too.

Prevention Measures

The best way to stop bacterial meningitis is to get vaccinated. Vaccines help protect against the germs that cause the illness, like meningococcal, pneumococcal, and Hib. It is important to get your vaccines on time. Also, washing hands and covering your mouth when you cough or sneeze helps stop the spread of germs.
