- Differential Diagnosis
- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

The more common symptoms of meningitis are fever, severe headache, stiff neck, bright lights hurting the eyes, drowsiness or confusion, and nausea and vomiting. In babies, the symptoms are more difficult to identify. They may include fever, fretfulness or irritability, difficulty in awakening the baby, or the baby refuses to eat. The symptoms of meningitis may not be the same for every person.
Viral ("aseptic") meningitis is serious but rarely fatal in persons with normal immune systems. Usually, the symptoms last from 7 to 10 days and the patient recovers completely. About 90% of cases of viral meningitis are caused by members of a group of viruses known as enteroviruses, such as coxsackieviruses and echoviruses. These viruses are more common during summer and fall months. Herpesviruses and the mumps virus can also cause viral meningitis. How is viral meningitis diagnosed? Viral meningitis is usually diagnosed by laboratory tests of spinal fluid obtained with a spinal tap; The specific cause of viral meningitis can be determined by tests that identify the virus in specimens collected from the patient; but these tests are rarely done; How is viral meningitis treated? No specific treatment for viral meningitis exists at this time; Most patients completely recover on their own; Doctors often will recommend bed rest; plenty of fluids; and medicine to relieve fever and headache; How is the virus spread? Enteroviruses; the most common cause of viral meningitis; are most often spread through direct contact with respiratory secretions (e g saliva; sputum; or nasal mucus) of an infected person; This usually happens by shaking hands with an infected person or touching something they have handled; and then rubbing your own nose or mouth.
The virus can also be found in the stool of persons who are infected; The virus is spread through this route mainly among small children who are not yet toilet trained; It can also be spread this way to adults changing the diapers of an infected infant; The incubation period for enteroviruses is usually between 3 and 7 days from the time you are infected until you develop symptoms; You can usually spread the virus to someone else beginning about 3 days after you are infected until about 10 days after you develop symptoms; Can I get viral meningitis if I’m around someone who has it? The viruses that cause viral meningitis are contagious; Enteroviruses; for example; are very common during the summer and early fall; and many people are exposed to them; However; most infected persons either have no symptoms or develop only a cold or rash with low-grade fever; Only a small proportion of infected persons actually develop meningitis; Therefore; if you are around someone who has viral meningitis; you have a moderate chance of becoming infected; but a very small chance of developing meningitis
