Meningococcal Disease: What Parents in South Africa Need to Know
Meningococcal disease is a serious and potentially life-threatening infection caused by the bacterium Neisseria meningitidis. Although it is relatively rare, it can progress very quickly and have devastating consequences, particularly in young children and adolescents. Understanding the risks, symptoms, and prevention options is key to protecting your family.
What is Meningococcal Disease?
Meningococcal disease most commonly presents as:
- Meningitis – inflammation of the lining around the brain and spinal cord
- Septicaemia – a severe bloodstream infection
Both forms can develop rapidly and require urgent medical attention.
How is it Transmitted?
The bacteria are spread through respiratory droplets, such as coughing, sneezing, or close contact (e.g. kissing or sharing utensils). It often spreads in environments where people are in close contact, such as households, schools, and daycare settings.
Signs and Symptoms
Early symptoms can be difficult to recognise, as they often resemble common viral illnesses. These may include:
- Fever
- Vomiting
- Fatigue
- Headache
As the disease progresses, more serious symptoms may appear:
- Neck stiffness
- Sensitivity to light
- Confusion or difficulty waking
- Seizures
- A purplish rash (a late and dangerous sign)
In infants, symptoms may also include poor feeding, irritability, and a bulging soft spot (fontanelle).
Severity, Survival, and Long-Term Effects
Even with appropriate medical care:
- Approximately 10–15% of people with invasive meningococcal disease may not survive
- Among survivors, up to 20% may experience permanent complications, including:
- Hearing loss
- Brain damage
- Learning difficulties
- Limb loss
In South Africa, meningococcal disease is not extremely common, but cases do occur each year, with children under 5 years and adolescents at highest risk.
Understanding the Different Strains
There are several strains (serogroups) of meningococcal bacteria. The most important globally and in South Africa include:
- A, C, W, Y
- B
Historically in South Africa, serogroup W has been one of the more commonly identified strains, but serogroup B (MenB) is also a significant cause of disease worldwide, particularly in infants and young children. This serogroup also has specific type of meningococcal bacteria that has unique surface proteins, which made it more difficult to target with traditional vaccines.
Vaccination: Your Best Protection
Menactra® (Current Programme)
Menactra protects against four strains: A, C, W, and Y. It has been part of the vaccination approach in South Africa for some time.
Schedule:
- Children under 2 years: 2 doses
- Children over 2 years: 1 dose
However, it is important to note that Menactra does NOT protect against serogroup B.
New in South Africa: Bexsero® (MenB Vaccine)
The Bexsero® vaccine has now become available in South Africa and provides targeted protection against meningococcal serogroup B, which was previously not covered.
Who can receive Bexsero?
- From as early as 10 weeks of age
- Suitable for children, adolescents, and adults — meaning the whole family can be vaccinated
Schedule:
- Typically 2–3 doses, depending on the age at which the first dose is given.
Why This Matters for Your Family
With both vaccines available, families now have the option of broader protection against the major strains of meningococcal disease. This is especially important for those at the highest risk of developing the disease:
- Infants and young children
- School-going children
- Teenagers and young adults
- Anyone living in a hostel or barrack
When to Seek Help
Meningococcal disease can worsen very quickly. If you notice symptoms such as high fever, unusual drowsiness, neck stiffness, or a rash, seek urgent medical care immediately.
