MENINGOCOCCAL MENINGITIS (MENVEO)
KEY POINTS
The bacterial agent of this disease is carried in the respiratory passages and transmitted through casual, prolonged contact in close quarters (shared air-space), such as in school dormitories and military barracks.
Meningococcal meningitis is year-round and worldwide, but tends to occur in certain locations epidemically (such as during the annual Islamic Hajj pilgrimage from Mecca to Medina).
In the U.S., most children are increasingly required by colleges to receive this vaccine prior to entry.
Disease: Neisseria meningitidis, a bacterium, can cause systemic illness by bloodstream infection (meningococcemia) or central nervous system infection (meningitis).
Symptoms:
Fever
Headache
Rash (hemorrhagic)
Neurological findings/deficits
Stiff neck
Light aversion (photophobia)
Transmission:
Airborne aerosols
Kissing
Contact with objects freshly contaminated with infectious nasal secretions (cigarettes, food, beverages, eating utensils, lip gloss)
Prevalence:
Sub-Saharan “meningitis belt” from Senegal and Guinea to Ethiopia in the dry season (December – June); also the Middle East and parts of Asia
Worldwide in overcrowded, impoverished areas; outbreaks also occur in childcare centers, schools and college dormitories, military barracks, etc.
Risk to travelers is low, but increases with length of stay in high-risk areas and contact with the local populace. The highest rates of meningococcal disease are in 16 – 21 yrs. old. It is the leading cause of bacterial meningitis in children 2 – 18 yrs-old in the U.S.
Treatment: Antibiotics
Prevention
The Vaccine (Menveo)
1. Menveo (2 – 55 yrs-old)
a. Covers meningococcal bacterial serogroups A, C, Y, and W135
b. Given intramuscularly, 0.5cc
c. Certified by Islamic Services of America as suitable for Hajj (Mecca to Medina) pilgrimage.
d. Dosing:
i.Non-Immune Compromised
1. Adults – 1 dose; booster every 5 yrs.
2. Adolescents
a. If 1st dose at 11 – 12 yrs, booster at 16 yr
b. If 1st dose at 13 – 15 yrs, booster at 16 – 18yrs (or up to 21yrs)
c. Children – booster after 3 yrs; if 1st dose at 16 yrs-old, no routine booster needed; unless high-risk exposure, as under “Targets”.
1. Non-immune compromised
2. Immune-compromised: Initially, 2 doses, 8 weeks apart
3. The vaccine should be received at least 1 – 2 weeks pre-travel for protection.
e. Side-Effects
i. Menveo: Common adverse effects are injection site pain, headache, muscle aches, malaise, and nausea.
ii. Guillaine-Barre’ syndrome (polyneuritis) risk unknown with meningococcal vaccine
f. Precautions/Contraindications
i. Postpone vaccination with moderate illness.
ii. Menomune may be a risk with latex allergy.
iii. In immune-compromised, response to the vaccine may be suboptimal (discuss with a physician).
iv. Use with pregnancy only if clearly indicated (definitive meningococcal disease risk).
v. Cautious use with breastfeeding.
g. Targets
i. Required for travelers to Saudi Arabia for Hajj pilgrimage or Umra
ii. Exposure to active meningococcal disease case
iv. HIV, persistent complement deficiency, diminished spleen function
v. Some travelers to Africa’s sub-Saharan “meningitis belt” during December – June (dry season)
vi. Travelers entering a country endemic for N. meningitidis when disease activity is increased
vii. Military recruits
viii. Occupations with exposure to N. meningitidis
ix. Those ≥ 11yrs-old
h. Special Considerations
i. Travelers arriving in the African meningitis belt, in addition to being required to show proof of vaccination, may also be given a preventive antibiotic (by mouth) at the point of entry.
ii. Anyone participating in the Hajj pilgrimage will be required to show proof of meningococcal vaccination within the prior 3 yrs.
iii. Meningococcal vaccine can be given concurrently with other vaccines except in those with sickle cell disease or without a spleen.
i. Other Preventive Measures
i. In areas where N. meningitidis is endemic (naturally present),
1.Avoid crowded places (to minimize direct human contact).
2. Avoid being near those sneezing and coughing.
3. Do not share drink containers, cigarettes, lip gloss/balm.
4. Wash hands frequently.
