Invasive Meningococcal Disease
Invasive meningococcal disease (IMD) is caused by the bacteria Neisseria meningitidis. It is an uncommon, but serious disease spread through close contact with someone who has the bacteria in their nose and mouth. IMD can lead to swelling of tissues surrounding the brain (meningitis) or bloodstream infection and causes complications such as hearing loss, amputations and death. IMD is treated with antibiotics. In Ontario, infants and students are routinely vaccinated to protect them from IMD.
