Kissing can also form an infection if that person throat or saliva contain bacteria. Not all bacteria that cause meningitis can be caused from an infectious person, but can also be caused by the food you eat that has Listeria bacterium, like soft cheeses, hot dogs, and sandwich meat.

DOH provides the following recommendations to prevent meningitis:

If you are experiencing symptoms of meningitis, seek medical care immediately. If meningitis is caught early in its stage, a person can recover fully with no lingering effects. Understanding the causes of meningitis and how it spreads will help you stay healthy and keep you from experiencing this life-threatening disease.
