Overview
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.
Risk Factors
Viral meningitis can affect anyone. But infants younger than 1 month old and people whose immune systems are weak are at higher risk for severe infection. People who are around someone with viral meningitis have a chance of becoming infected with the virus that made that person sick, but they are not likely to develop meningitis as a complication of the illness.
Factors that can increase your risk of viral meningitis include:
- Age
- Viral meningitis occurs mostly in children younger than age 5.
- Weakened immune system.
- There are certain diseases, medications and surgical procedures that may weaken the immune system and increase risk of meningitis.
