The question is "contagious with WHAT?"
If it's viral meningitis, then the only action necessary is that you be alert for the signs and symptoms of meningitis (headache, stiff neck, fever, nausea)....
There IS NO PREVENTATIVE MEASURES to take for viral meningitis exposure. If your health dept passes out prophylactic antibiotics for a viral meningitis exposure than SOMEONE needs to educate them about CDC guidelines.
Now, if the person turns out to have BACTERIAL meningitis, all bets are off, but then they'll probably want to determine your level of exposure.
Too many people create a sense of panic when they hear the word "meningitis." What needs to be determined is the TYPE of meningitis and THEN CDC guidelines should be followed.
off soapbox now.
