Abstract:
Meningococcal disease continues to be a worldwide problem. This review examines the impact meningococcal disease has on international travel and vice versa the impact international travel has on the intercontinental spread of meningococci. The risk of meningococcal disease to the endemic population differs from that of travellers. The best documented risk of meningococcal disease among travellers has been in Hajj pilgrims for Mecca and Madina in Saudi Arabia. In response to the recent Hajj associated outbreak of W135 meningococcal disease, quadrivalent meningococcal vaccine (against serogroups A/C/Y/W135) became a visa requirement. In view of increasing worldwide reports of Y and W135 meningococcal disease, there should be a switch in recommendation from the bivalent (against A& C) to the quadrivalent vaccine for all travellers.
Insights
Meningococcal disease poses global travel risks. Travelers, especially pilgrims, face unique threats, necessitating a shift to quadrivalent vaccines for broader protection against serogroups A, C, Y, and W135.
Area of Science:
- Public Health
- Infectious Diseases
- Travel Medicine
Background:
- Meningococcal disease remains a significant global health concern.
- International travel facilitates the spread of meningococcal bacteria across continents.
- Travelers face distinct risks compared to endemic populations.
Purpose of the Study:
- To review the impact of meningococcal disease on international travel.
- To examine how international travel influences meningococcal spread.
- To recommend updated vaccination strategies for travelers.
Main Methods:
- Literature review of meningococcal disease epidemiology and travel.
- Analysis of disease patterns in traveler populations, particularly pilgrims.
- Evaluation of vaccine efficacy and recommendations.
Main Results:
- The Hajj pilgrimage is a well-documented high-risk event for meningococcal disease.
- Recent outbreaks, notably W135, have led to vaccine requirements for specific travel.
- Increasing global reports of serogroups Y and W135 are evident.
Conclusions:
- Quadrivalent meningococcal vaccines (A/C/Y/W135) are crucial for travelers.
- A transition from bivalent (A&C) to quadrivalent vaccines is recommended for all international travelers.
- Enhanced surveillance and vaccination policies are needed to mitigate travel-related risks.
