NL Health Services declares outbreak of invasive Meningococcal Disease in central Newfoundland
Newfoundland and Labrador Health Services is advising the public of an outbreak of invasive meningococcal disease (IMD) following three lab confirmed cases within Central Newfoundland and Labrador.
Public Health has conducted case and contact management. All individuals considered to be close or high-risk contacts have been notified and offered vaccination for N. Meningitidis B. At this time, the overall risk to the general public is low.
Although uncommon, IMD is a serious bacterial infection that can lead to infections in the lining of the brain and spinal cord (meningitis), and infection of the bloodstream (meningococcemia), which require immediate medical treatment. The bacteria is spread through close, prolonged face‑to‑face contact such as:
- kissing, coughing or sneezing
- sharing drinks, water bottles, mouth guards or eating utensils
- sharing toothbrushes, cigarettes, vapes or lip balms
- sharing sleeping arrangements.
It is important to note that the bacteria is not spread through casual contact or by breathing the same air as someone with meningococcal disease.
Symptoms of IMD typically develop two to 10 days (usually three to four days) after exposure and may include:
- high fever
- purplish, bruise‑like rash
- severe headache
- stiff neck
- vomiting
- drowsiness, confusion, or irritability
As a precaution, residents are encouraged to be aware of the symptoms of IMD and to practice preventative measures such as avoiding sharing items that come into contact with saliva, covering coughs and sneezes, practicing regular hand hygiene, and staying up to date with routine immunizations. If symptoms of invasive meningococcal disease develop, it is important to immediately seek medical treatment.
Immunization remains the best defense against common meningococcal strains and is included as part of Newfoundland and Labrador’s publicly funded childhood and school-based immunization program. Vaccination is safe and highly effective in reducing the risk of severe illness.
Current guidelines recommend meningitis B vaccination for individuals exposed to this specific strain of the disease who have been identified as close or high-risk contacts by Public Health. Individuals who have not been directly contacted by Public Health are not considered close contacts and, therefore, do not require meningitis B vaccination as a post-exposure measure at this time.
