External meningitis is a potentially life-threatening inflammation of the membrane surrounding the brain and spinal cord that is caused by an external source such as an infection or injury. The spelling of "external meningitis" is broken down phonetically as /ɪkˈstɜː(r)nəl məˈnɪnˌdʒaɪtɪs/. The stress falls on the second syllable of "external" and the first syllable of "meningitis". This pronunciation aids in understanding the word's meaning and usage in medical contexts. Those experiencing symptoms of external meningitis should seek immediate medical attention as the condition can have serious repercussions if left untreated.
External meningitis refers to inflammation of the meninges, the protective membranes that envelop the brain and spinal cord, caused by an external source or factor. It is a condition characterized by the invasion of infectious agents into the meninges, leading to inflammation and subsequent symptoms.
Typically, external meningitis is caused by bacteria, fungi, or other pathogens that are introduced to the body from an external source, such as an infection in another part of the body or direct contact with contaminated substances. This differs from other forms of meningitis, such as viral or aseptic meningitis, which are caused by internal factors.
Symptoms of external meningitis may include severe headaches, fever, stiff neck, sensitivity to light, nausea, vomiting, and in severe cases, altered consciousness or seizures. Prompt medical attention is crucial as external meningitis can lead to serious complications, such as brain damage, hearing loss, or even death, if left untreated.
Diagnosis of external meningitis involves a series of tests, including analyzing cerebrospinal fluid obtained through a lumbar puncture, and blood cultures, to identify the causative pathogen. Treatment typically involves the administration of antibiotics, antifungals, or antivirals, depending on the specific causative agent.
Prevention of external meningitis may include practicing good hygiene, avoiding exposure to contaminated substances, maintaining a healthy lifestyle, and receiving vaccinations, such as the meningococcal vaccine, which can protect against certain types of bacterial meningitis.

The term "external meningitis" is not a standard medical term or a common term used in the field of medicine. The word "meningitis" itself, however, does have a well-known etymology.
The word "meningitis" originates from the Greek word "meninx", meaning membrane, combined with the suffix "-itis", denoting an inflammation. In medical context, "meninges" refers to the protective membranes that cover the brain and spinal cord. Thus, "meningitis" refers to the inflammation of these protective membranes, usually caused by an infection.
However, the term "external meningitis" does not align with this etymology and likely does not have established roots in medical terminology. It is always recommended to consult with a healthcare professional to obtain accurate information about specific medical conditions.
