Because my toddler cannot talk, what symptomss should i look for if there might have been an exposure to meningitis?

Meningitis: This is characterized by fever, chills, headache, sensitivity to light and/or sound, nausea and vomiting, changes in sensorium (in your toddler alterations in behavior), and neurological abnormalities. If the baby is acting differently than normally, not eating, fussy, crying incessantly, warm to touch, etc., see a pediatrician asap. Unless the exposure was intimate - unlikely to get meningitis.

Meningitis ?: Symptoms would include fever, decreased alertness or irritability, stiff neck. If you have any question about this, speak to your pediatrician.
