Usually there is no increased spread within schools or at recreational or social events. Casual contact such as being in the same classroom or sitting at a table with an infected person does not increase the risk of infection. Severe headache, vomiting, and stiff neck are the most common signs of meningococcal disease. High fever and irritability are signs in a very young child. If there is infection in the blood, a purplish skin rash that looks like bruising may also occur.
Basic hygiene can help prevent meningococcal disease.
Wash hands before eating and after coughing and sneezing. Do not share forks, spoons, glasses, cigarettes, lipstick, food, sports water bottles, or other items that may contain saliva. Cover your nose and mouth when coughing or sneezing to stop the spread of any germs. Inform public health staff, or your doctor, if your child has been in close contact with someone who has the disease. The antibiotic rifampin is used to treat people who have been in close contact with someone who has meningococcal disease.
