Is encephalitis contagious?

We have all heard of the occurrence of tetanus. In fact, when our skin trauma is relatively small, the lack of internal oxygen can easily cause tetanus in our skin. In fact, the same principle applies to encephalitis. Encephalitis is actually an inflammation of the brain. In daily life, we can judge the occurrence of disease in a timely and accurate manner through relevant symptoms.

Many people have a question about encephalitis, that is, is encephalitis contagious? Encephalitis is an infectious disease, which is mainly caused by bacteria in the air entering our brain. Therefore, when communicating with patients, you must pay attention to choosing a more appropriate ventilated environment.

1. Systemic toxic blood symptoms

Fever, headache, body aches, nausea, vomiting, fatigue. A few patients have hemorrhagic rash and myocarditis symptoms.

2. Neurological symptoms

Impaired consciousness, meningeal irritation signs. Flaccid paralysis of the cervical and scapular muscles may occur, causing the head to droop and the arms to be unable to be raised, resulting in the person tottering and helpless. Involvement of cranial nerves and lower limbs is rare. Paralysis can be recovered in about 2 to 3 weeks, and about half of the muscles will atrophy. Mild cases may have no obvious neurological symptoms.

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.

Meningitis is an inflammation of the brain. The meninges are the thin membranes that cover 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.

For example, the infection may come from another part of the body, such as the lungs, that is infected. 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.

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.

People who work in the same room with patients, work in nurseries, or have direct contact with patients' oral secretions (such as kissing) are considered to be a high-risk group for infection.

If you often move among people, you may worry about whether encephalitis is contagious, and you should keep a certain distance from encephalitis patients. Patients should not develop an autistic mentality in daily life. We should be aware that the brain is the most important part of our body, so we must do a good job of disease prevention in daily life to ensure physical health and disease suppression. If you find any adverse symptoms in your daily life, you should seek medical attention in time and listen to the doctor's advice.
