Aseptic meningitis

Meningitis happens when the brain's lining becomes inflamed. This lining is called the meninges. Aseptic meningitis occurs when there are signs of meningitis. However, when a sample of brain fluid is taken, bacteria do not grow. This condition is often treatable. In many cases, recovery takes 7–10 days.

• Viral infection due to:
  • Enterovirus (e.g., Hand, Foot, and Mouth Disease; Conjunctivitis)
• Other viruses, such as West Nile Virus
• Parasitic infection (e.g., Lyme Disease)
• Mycoplasma (a type of pneumonia)
• Tuberculosis
• Fungal infection
• Bacterial Meningitis that has not been fully treated
• Certain drugs
• Autoimmune diseases (e.g., Sarcoidosis, Behcet's Disease)

These factors increase the chance of developing aseptic meningitis:

• Being exposed to someone with a viral illness
• Working in a daycare or healthcare setting
• Having a compromised immune system
• Taking certain drugs (e.g., non-steroidal anti-inflammatory drugs)
• Being a child or teenager (affects children and teens more often than adults)
