Is meningitis contagious?

First of all, you should know that meningitis is caused by inflammation of the brain. Meningitis is contagious and can be spread through the air through germs and saliva in coughs. However, there is no indication that the infected people have developed meningitis, but it still needs attention and vigilance.

In professional mild cases, there may only be headache, dizziness, neck stiffness and other symptoms of serous meningitis. When the lesions are severe and diffuse, there may be symptoms such as impaired consciousness, delirium and agitation, cranial nerve paralysis, limb paralysis, involuntary movements, urinary and bowel disorders, and convulsions. As the disease progresses further, the patient may fall into a deep coma and be in a state of decerebrate or decorticate. Sometimes the lesions may be limited to the brainstem, spinal cord and other parts, causing corresponding symptoms called brainstem inflammation or myelitis respectively.

1. Meningitis is an inflammation of the brain. The meninges are the thin membranes covering the brain and spinal cord. This meninges has three layers, the first is the outer thin membrane, called the dura mater, which is connected to the skull;

The second layer is the arachnoid membrane; the last layer is the innermost layer, called the pia mater, which is attached to the brain. Infections in these membranes are usually caused by invasion of bacteria or viruses. There are several ways that infection can reach the meninges.

2. For example, the infectious agent can be introduced from other parts of the body such as the infected lungs. Spread through the bloodstream. They can also spread from infected ears or sinuses through spaces in the skull and into the brain.

If you have a head injury and there is a crack in the skull, infection can easily enter the brain. There are many forms of meningitis and varying degrees of inflammation. This mostly depends on which microorganisms or viruses are causing the disease.

3. When coughing, talking, or sneezing, a large amount of bacteria-carrying droplets are sprayed out, polluting the air. Once a healthy person inhales them, when the body's immunity and resistance are reduced, the meningococci will enter the bloodstream through the respiratory tract and then reach the brain, causing inflammatory changes in meningitis and a series of clinical symptoms.
