Meningococcal disease is caused by the bacteria Neisseria meningitidis. It is very rare, however once infected, it can be very serious.
Normally, some people get the infection in their throat or nose without getting sick. In rare cases, the infection can cause serious illness and spread to others. It can lead to meningitis (a brain infection), septicemia (a blood infection), as well as complications like hearing loss, brain damage, loss of limbs and even death.
Meningococcal disease can affect people of any age. However, it is most common in children under five years old, teens and young adults who are not vaccinated against the disease.
There are many strains of meningococcal infection that can cause illness. Strains A, B, C, Y, W have a vaccine to prevent infection. See a health care provider right away if you have any symptoms of meningococcal disease.
Meningococcal disease spreads through close, direct contact with saliva from the mouth or mucus from the nose of someone who has the disease.
Examples include:
A person can spread meningococcal disease up to seven days before becoming sick and until 24 hours after starting antibiotic treatment.
Symptoms typically start three to four days after exposure but you may start to have symptoms between two to 10 days after being exposed to the bacteria.
Symptoms include:
Children with meningococcal disease may be more irritable or fussy than normal. Infants can have a high-pitched cry, an arched back, difficulty waking, decreased appetite or difficulty feeding.
See a health care provider right away if you develop symptoms within 10 days of being in close contact with a person who has meningococcal disease.
Anyone who has been in close direct contact with a person who has meningococcal disease is at risk.
Those most at risk of exposure include:
Those most at risk of severe meningococcal disease include:
Getting a meningococcal vaccine is the best protection against meningococcal disease.
There are many strains of meningococcal infection that can cause illness. Strains A, B, C, Y, W have a vaccine to prevent infection. Meningococcal vaccines provide strong protection against specific strains of meningococcal bacteria. You cannot get the disease from the vaccine because it does not contain live bacteria.
The vaccine is safe and effective. Common side effects include pain and redness where the vaccine was given, headache, as well as feeling tired or unwell for a short time after getting the vaccine.
In rare cases, serious allergic reactions, such as trouble breathing, rash, as well as swelling in the throat and face may occur. Allergic reactions can be treated and are usually temporary. There are no long-term side effects from these vaccines.
A vaccine will be recommended, and available for free if you are a close contact of someone who had severe meningococcal illness caused by one of the vaccine preventable types (A, B, C, Y, W).
Toronto Public Health strongly advises adults born in 1986 or later who have not received a dose of meningococcal vaccine to get this free vaccine as soon as possible to be protected.
If you got the meningococcal vaccine when you were a baby or young child but did not get one when you were a teenager or adult, it is recommended to get another vaccine dose. If you cannot find your vaccination history, you can safely get a meningococcal vaccine dose.
Contact your health care provider to get the vaccine.
OHIP, health insurance, or immigration status is not needed to get the vaccine. If you do not have OHIP or health insurance, contact a clinic that provides free health care to uninsured people. A piece of ID is needed to confirm your age. You can get the meningococcal vaccine at the same time as other vaccines, such as flu or COVID-19 vaccines.
Toronto health care providers can order the Meningococcal ACYW vaccine from Toronto Public Health.
If you or your child(ren) were in close contact with someone with meningococcal disease, watch for symptoms for 10 days after your last contact with that person.
If you think you or your child may have meningococcal disease, it is important to:
People diagnosed with meningococcal disease or suspected of having it should stay home and avoid sharing food, drinks, or objects that you put in your mouth such as smoking and vaping products or musical instruments, and avoid activities such as kissing while infectious.
Meningococcal disease is diagnosed based on symptoms and laboratory tests including a blood test or testing of cerebrospinal fluid (fluid near the spinal cord). Treatment for meningococcal disease includes antibiotics which can prevent you from getting seriously sick and spreading the bacteria. Hospitalization may be needed for serious infections.
Toronto Public Health follows up and provides guidance to anyone who lives in Toronto that has meningococcal disease, as well as their close contacts. Close contacts may be given an antibiotic and/or a meningococcal vaccine.
