What is Viral Meningitis?
Viral meningitis, also known as aseptic meningitis, is a condition that causes inflammation of the meninges, which are the protective membranes that cover the brain and spinal cord. Unlike bacterial meningitis, which is caused by bacteria, viral meningitis is caused by viruses. The most common viruses that cause viral meningitis include enteroviruses, which are a group of viruses that can cause various infections, such as the common cold, hand-foot-and-mouth disease, and viral gastroenteritis. Other viruses that can cause viral meningitis include herpes simplex virus, mumps virus, and West Nile virus. Viral meningitis can affect people of all ages, but it is most common in children under the age of 5. The condition is usually mild and resolves on its own within 7 to 10 days. However, in some cases, viral meningitis can cause serious complications, such as brain damage, hearing loss, and seizures.
Symptoms of Viral Meningitis
The symptoms of viral meningitis can vary from person to person, but they usually develop within 3 to 7 days after exposure to the virus. The most common symptoms of viral meningitis include: – Fever – Headache – Stiff neck – Nausea and vomiting – Sensitivity to light – Rash – Confusion or irritability – Seizures In some cases, viral meningitis can cause more severe symptoms, such as high fever, seizures, and loss of consciousness. If you or someone you know experiences any of these symptoms, seek medical attention immediately.

2. How is viral meningitis diagnosed?
Viral meningitis is diagnosed through a combination of physical examination, medical history, and laboratory tests.
