Invasive meningococcal disease (IMD) is a severe, sometimes fatal, infection. It is caused by the bacterium Neisseria meningitidis (meningococcus). IMD can affect many body sites causing different syndromes such as meningitis (infection of the lining of the brain), sepsis (blood poisoning) and pneumonia (lung infection).
Anyone can get IMD. Infants under one (1) year of age traditionally have had the highest rates of disease, however, in recent years in NYC this has not been the case. Clusters of cases and outbreaks do occur but are rare in the United States.
Early symptoms are flu-like with fever, chills, weakness and muscle aches. These symptoms can rapidly progress over the next day or so to include, headache, stiff neck and widespread rash. People who experience these symptoms, especially those with HIV-infection, should seek medical care immediately.
The symptoms may occur two (2) to 10 days after exposure, but usually within five (5) days.
IMD is spread by prolonged close contact with nose or throat discharges from an infected person or carrier. Examples of prolonged contact include living in the same household or intimate activities, like kissing and sexual contact.
IMD is usually diagnosed by laboratory identification of the bacteria from either the blood or spinal fluid.
Yes. There are vaccines that will protect against a number of the strains of the meningococcal organism. Talk to your health care provider about which vaccine is right for you or your loved ones.
It is recommended that the following groups get routinely vaccinated:
In addition, vaccination is recommended for persons aged 2-55 who are increased risk of IMD:
In addition to the groups listed above, the Health Department strongly recommends vaccination in men who have sex with men (MSM) who are either HIV-infected or regularly have intimate contact with other men they’ve met online, through a digital application (“app”) or at a bar or party. In NYC and some other cities, there have been outbreaks of IMD MSM that have been associated with use of web or handheld applications, as well as parties and other gatherings, focused on meeting potential sex partners. Many of these cases occurred in MSM living with HIV.
Talk to a doctor if you’re worried you might be at risk and should get vaccinated.
Adults at risk for IMD should ask their provider if they can get vaccinated in the office. If not, many pharmacies offer meningococcal vaccine. Locations are listed on the NYC Health Map. Most pediatric care providers will have meningococcal vaccine for their patients.
No. However, New York State public health law requires that all students attending college, university, boarding schools, or spending 10 or more nights at a children's sleep away camp be informed about IMD and be aware of vaccine.
Only people who have been in prolonged close contact (household members, intimate contacts, health care personnel performing mouth-to-mouth resuscitation, day care center playmates, etc.) need to be considered for preventive treatment. The Health Department will contact such people to advise them about the need for antibiotics. Casual contact that occurs in a regular classroom, office, factory or other work setting is not usually enough to cause concern.
Several antibiotics are very effective in eliminating the bacteria from the nose and throat. Penicillin remains the recommended treatment.
