Manitoba Urges Vaccination Amid Surge in Meningococcal Disease Cases

Public health officials in Manitoba are urging residents to get vaccinated against Invasive Meningococcal Disease (IMD) following a significant rise in reported cases since December 2023. The call for action comes after the province recorded four deaths and 23 confirmed cases linked to serogroup W of the disease, which is approximately five times the expected incidence.

Health Minister Uzoma Asagwara emphasized the importance of vaccination during a news conference on Wednesday. He encouraged Manitobans to check their vaccination records and consult with healthcare providers to ensure they are up to date with their meningococcal immunizations. “Ensuring everyone who is eligible gets vaccinated is important for reducing transmission and preventing new cases,” Asagwara stated.

The majority of IMD cases have emerged from the Northern Health Region, with Indigenous communities disproportionately affected. Infants under 12 months are at the highest risk, although cases have been reported across all age groups. The disease can develop rapidly, with symptoms appearing between two and ten days after exposure. Symptoms include a dark purple rash that does not fade when pressed, severe headaches, fever, nausea, vomiting, sensitivity to light, and a stiff neck.

IMD is a serious bacterial infection, and approximately one in ten people infected do not survive. Survivors may face long-term consequences, including hearing loss, brain damage, or limb amputations. The disease is caused by five strains of meningococcal bacteria: A, B, C, Y, and W.

Vaccination Guidelines and Recommendations

In response to the outbreak, Manitoba health authorities are reminding parents of the vaccination schedule for their children. Routine immunizations are typically administered at 12 months and again in Grade 6. Additionally, infants between six weeks and 12 months can receive up to two extra doses of the meningococcal conjugate quadrivalent (Men-C-ACYW) vaccine if they meet specific criteria. These include residing in or frequently visiting Indigenous communities in Manitoba or having household visitors from those communities.

Children born between January 1, 2020, and February 28, 2023, are eligible for the Men-C-ACYW vaccine regardless of previous Men-C-C vaccinations. Those who missed doses of either vaccine at the appropriate ages can still receive the Men-C-ACYW vaccine.

Receiving the Men-C-ACYW vaccine is crucial for protecting individuals against IMD and controlling the outbreak by decreasing the number of carriers in the population. Meningococcal bacteria can spread through respiratory droplets, close contact, and sharing personal items like water bottles or food. Many individuals carry the bacteria without showing symptoms, creating a risk of unintentional transmission.

People seeking information on their eligibility for meningococcal immunization can visit the Manitoba public health website. The province’s proactive measures are aimed at safeguarding the health of its communities and minimizing the impact of this serious bacterial illness.
