The next set of age group, like children, have similar but varying symptoms of sore throat, rashes, and diarrhea. In adults, symptoms and the harshness of them tend to be less in duration. Additionally, the probability of developing aseptic meningitis increases when patients have a case of mumps or herpes.Symptoms of meningitis caused by an acute viral infection last between one and two weeks. When aseptic meningitis is caused by cytomegalovirus 20 percent of individuals face mortality or morbidity. If left untreated it can affect an individuals hearing and learning abilities. Causes
The most common cause of aseptic meningitis is a viral infection, specifically by enteroviruses. In fact, 90 percent of all meningitis cases that are viral are caused by enteroviruses. Other viruses that may cause aseptic meningitis are varicella zoster virus, herpes, and mumps. Other causes may include mycobacteria, fungi, spirochetes, and complications from HIV. Side effects of certain drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics (e.g., trimethoprim-sulfamethoxazole or amoxicillin), and antiepileptic drugs can also cause aseptic meningitis.There are multiple types of aseptic meningitis that are differentiated based on their cause. Viral meningitis
Enterovirus (EV) caused meningitis. This is the most common cause of viral meningitis, with 90% of viral meningitis cases being caused by EVs. Human immunodeficiency virus (HIV)
Mumps meningoencephalitis
Mosquito carried viruses of the flavivirus family. Saint Louis encephalitis (SLE) and West Nile virus (WNV) are the most typical. Specific types of Herpes can result in aseptic meningitis. These are (HSV)-1, (HSV)-2, varicella-zoster virus, and (HHV6).
Bacteria
Lyme disease
Syphilis
Leptospirosis
Fungi
Cryptococcal infection
Coccidioidal infection
Drug-induced aseptic meningitis (DIAM)
Irritation of the meninges from drugs administered directly to the spinal canal or subarachnoid space. The hypersensitivity to the drug results in an immune response. Autoimmune diseases
Systemic lupus erythematosus. Cancer-caused aseptic meningitis such as neoplastic meningitis
This affects about 5% of all cancer cases, with a predominance in leukemias. Neurosarcoidosis

Diagnosis
The term aseptic can be misleading, implying a lack of infection. On the contrary, many cases of aseptic meningitis represent infection with viruses or mycobacteria that cannot be detected with routine methods. Medical professionals will take into consideration the season of the year, the medical history of the individual and family, physical examination, and laboratory results when diagnosing aseptic meningitis.One common medical test used when diagnosing aseptic meningitis is lumbar puncture. A medical professional inserts a needle between two vertebrae to remove cerebrospinal fluid (CSF) from the spinal cord. The cerebrospinal fluid collected from the lumbar puncture is analyzed by microscope examination or by culture to distinguish between bacterial and aseptic meningitis. Samples of CSF undergo cell count, Gram stains, and viral cultures, and polymerase chain reaction (PCR). Polymerase chain reaction has increased the ability of clinicians to detect viruses such as enterovirus, cytomegalovirus, and herpes virus in the CSF, but many viruses can still escape detection. Other laboratory tests include blood, urine, and stool collection. Medical professionals also have the option of performing a computed tomographic (CT) scan or magnetic resonance imaging (MRI), these tests help observe calcifications or abscesses.
