Meningococcus spreads through respiratory secretions shed by an infected person or an asymptomatic carrier. When someone coughs, sneezes, or talks, droplets containing Neisseria meningitidis can be inhaled or deposited on the mucous membranes of nearby people, leading to transmission in close-contact situations. This droplet-based route is the typical means of spread, which is why outbreaks occur in settings with close, rapid person-to-person contact. Fomites—objects or surfaces—are not a major route for this organism, since it does not usually survive well on inanimate surfaces and transmission via contaminated surfaces is not the common pattern. So the statement that transmission occurs via droplet infection from respiratory secretions of an infected person or carrier aligns with how meningococcus is commonly transmitted.
