In particular, even with appropriate therapy, meningococcal disease is often fatal 2  p1a and approximately 20% of those who survive will suffer from complications, including hearing loss, skin scarring, amputations and neurological fall out.2 p1b Therefore, even though the incidence of meningococcal disease is relatively low in South Africa, all South Africans, starting from 9 months of age, should be vaccinated to protect against meningococcal infection.2 p2a, p3a

Even though the incidence of meningococcal disease is relatively low in South Africa, all South Africans, starting from 9 months of age, should be vaccinated to protect against meningococcal infection.

Meningococcal disease is endemic to South Africa.2 p1c Sporadic cases occur throughout the year and the incidence peaks during the winter and spring months of May to October.3,4 3. p7a; 4. p5a Although all ages may be affected, the highest incidence occurs among children younger than 10 years, and especially infants.3,4  3, p7e; 4. p5c. p6 fig3 Over the last 10 years, the average incidence per 100 000 people was 1 overall and 8 among infants.2 p1c More than 1 in every 6 individuals with the disease died.2 p1c

In South Africa, 75% of meningococcal disease has been caused by serotypes A, C, W and Y.p3d

From 1 January to 30 September 2019, 74 laboratory-confirmed, invasive meningococcal disease episodes were reported by the GERM-SA surveillance program.p7b Two thirds of these occurred during the first 6 months of the year.4  p5b Most of the affected people were from Gauteng (34%), Western Cape (30%), KwaZulu Natal (14%) and the Eastern Cape (12%).p7d Approximately 60% were due to Neisseria meningitidis serotypes Y, W and C.p7g

Up to 10% of the population are asymptomatic carriers of N. meningitidis, which is a prerequisite for invasive disease.2 p1d However, carriage is higher among children and adolescents, 2 p1d and, in some areas, up to 25% of teenagers (15 to 19 years of age) may unknowingly carry and transmit the disease to others.2,5   2.p1d; 5. p573b

Person-to-person spread occurs from the nasopharynx via respiratory droplets.p1d Risk factors for colonisation include intimate personal contact (including kissing), passive smoking, pub attendance, overcrowding, attendance at mass gatherings and previous antibiotic use.p1e Consequently, in a person presenting with features of meningitis, risk factors that suggest infection with meningococcus include exposure to childcare facilities, learning institutions and military barracks.1 p7a Clinical features characteristic of this pathogen include a nonblanching petechial rash (some have a maculopapular rash) and conjunctival lesions.p7a Nevertheless, invasive meningococcal disease should be considered in anyone who presents with sudden onset of fever, vomiting, headache, neck-stiffness or petechial rash.p7c Acute meningitis is a medical emergency, requiring immediate antibiotics and hospital admission.1 p6a It is a category 1 notifiable medical condition, and each case should be reported immediately to ensure contact tracing, responsible prescription of chemoprophylaxis and case counting.p7f

Vaccination is recommended especially for people who are at higher risk of acquiring the disease.p2a In addition to immunocompromised individuals, consideration should be given to healthy infants, young children attending creche and school children, university students, army recruits and others living in crowded conditions, people attending a mass gathering (e.g., sporting event) and those travelling to hyperendemic areas.p2b,c; p3a,b,g

Menactra is a quadrivalent meningococcal vaccine targeting serotypes A, C, W and Y, which on average, have been the most common N. meningitidis serotypes in South Africa over the past 10 years. 2,6  2. p3d, p2e; 6. a Unlike polysaccharide vaccines, because it is a protein-conjugate polysaccharide vaccine, Menactra stimulates immune memory and induces mucosal immunity, so in addition to providing protection against invasive disease, it also decreases carriage of the organism.p2 f,g; p3d It is indicated for routine active immunisation for individuals aged 2 to 55 years.b Children older than 2 years, adolescents and adults require a single primary dose.2,6  2. p3 e,f; 6c Local guidelines also recommend vaccination of  infants aged 9 to 23 months, who require two primary doses separated by an interval of 12 weeks.p3e
