What Exactly Are The Root Causes Of Meningitis?

Jan 09, 2023 By Madison Evans

Although there are a few distinct causes of meningitis, they all have the same effects: Infection occurs when a bacteria, fungus, virus, or parasite makes its way to the brain or spinal cord from elsewhere in the body through the bloodstream, nerve terminals, or even a dormant reactivation in the nervous system.

There, it grows into a more severe in fection in the lining or fluids around these crucial bodily organs. Unlike infectious meningitis, which is caused by bacteria or viruses, non-infectious meningitis is brought on by something other than an injury.

What About A Meningitis Vaccine?

Several strains of bacterial meningitis can be prevented using a vaccination. The meningococcal type, caused by Neisseria meningitides, is preventable with a vaccination. Bacterial meningitis is more deadly if not treated promptly, while viral meningitis is more prevalent. Therefore, the two main meningitis vaccines target bacteria:

  • The vaccination in the meningococcal conjugate protects against four of the most prevalent bacterial serotypes. In particular, if you keep up with booster doses, the effects will stay longer, and the protection they provide will be stronger.
  • The protection period for the Serogroup B meningococcal, or MenB, vaccination is significantly shorter since it is only effective against a single strain of the disease. This vaccination is only approved for use in specific populations.

So, Who Exactly Should Get The MenB Vaccine?

The Centers for Illness Control and Prevention advises that everyone 10 or older at elevated risk for meningococcal disease receive the MenB vaccination.

Particular Circumstances

The Centers for Disease Control and Prevention (CDC) recommends a meningitis vaccination for the following situations, while most younger children and adults do not require it:

  • certain medical disorders
  • People whose jobs require them to interact with microorganisms
  • destinations on your upcoming trip where meningitis is prevalent
  • everyone at higher risk of contracting meningococcal illness because of the current epidemic

If you or your kid fit any of the following characteristics, you should talk to your doctor about being vaccinated against meningitis.

How Do Doctors Cure Meningitis?

The therapy you receive depends on what caused your meningitis in the first place.

  • Bacterial meningitis necessitates rapid hospitalization. Brain injury and death can be avoided with prompt diagnosis and treatment. Antibiotics and steroids given intravenously are the standard treatment for bacterial meningitis.
  • Parasitic meningitis treatment options include symptomatic relief and antimicrobial therapy. Depending on the underlying reason, this variety may resolve itself without antibiotic therapy.
  • Virus-related meningitis may get well on its own, but there are cases where antiviral drugs given intravenously are necessary.
  • The best way to treat chronic meningitis is to eliminate the underlying cause, which might be as simple as a fungal infection or as complex as rheumatoid arthritis.

How Easily Can Meningitis Spread?

Some strains of meningitis are not infectious. Meningitis caused by fungi, parasites, or other infectious diseases is not communicable.

Infectious diseases like meningitis caused by viruses are spread easily. Contact with infectious bodily fluids, such as mucus, feces, or saliva, is the primary transmission route. Sneezing and coughing release droplets of fluid, which can then be inhaled and transferred to other people.

Most cases of meningitis are caused by viruses, although bacterial meningitis, the most severe type, can also be communicable, especially if it is meningococcal meningitis.

Childhood Meningitis

When a baby has meningitis, the symptoms of infection might seem different than in an adult. Examples of such symptoms include:

  • fever
  • a sore neck or body
  • Crying at a high pitch
  • actions that cannot be consoled
  • drowsy and hard to wake up

Infant meningitis caused by viruses is not uncommon. Symptoms like fever, sore throat, sickness, and untreated diarrhea might lead to its development. Viral meningitis is caused by the same viruses that trigger these more prevalent illnesses.

Childhood Meningitis

Kids are at greater risk for meningitis when they are older and in secondary school or college. Whether caused by a virus or bacterium, children will have signs and symptoms identical to those seen in adults. Among these are:

  • Acute Fever
  • sore muscles and a stiff neck
  • feeling lost or disoriented
  • nausea
  • vomiting

Adults With Meningitis

After reaching maturity, a person is at a lower risk of developing some meningitis. That's owing, in large part, to the fact that things have shifted. Some strains of meningitis are easily spread in institutional settings like schools and dormitories.

The risk of becoming infected decreases after a young adult no longer frequents these places. However, the elderly are especially vulnerable because of their weakened immune systems, and illnesses spread rapidly in assisted living facilities.

How Can One Identify Meningitis?

Initial steps in diagnosing meningitis include gathering medical history and doing a physical exam. Clues including age, place of living (home or dorm), and childcare attendance might be useful. You may expect the following to be checked throughout your doctor's physical examination:

  • fever
  • Dermatological Disorders
  • increased pulse rate
  • Constriction in the neck
  • Diminished Awareness
