How Meningococcal Disease Spreads
Meningococcal disease is caused by the bacterium Neisseria meningitidis. It spreads through direct contact with respiratory and throat secretions, such as saliva. Close and prolonged contact increases the chance of transmission.
Common Settings and Risk Factors
Transmission is more likely in crowded settings, such as dormitories, households, and during travel. Activities involving kissing, coughing, or sharing utensils, cups, or cigarettes raise the risk of spread.
Prevention and When to Seek Help
Vaccination is the most effective way to reduce meningococcal disease spread. Good hygiene, including handwashing and avoiding sharing personal items, also helps. Seek urgent medical care if symptoms such as sudden fever, stiff neck, or confusion appear.
