Chin BS, Kim JY, Gianella S, Lee M - Infect Chemother (2016)

Bottom Line: People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV.Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas.Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business.

ABSTRACT

Background: Travel-related risks for infectious diseases vary depending on travel patterns such as purpose, destination, and duration. In this study, we describe the patterns of travel and prescription of vaccines as well as malaria prophylaxis medication (MPM) at a travel clinic in South Korea to identify the gaps to fill for the optimization of pre-travel consultation.

Materials and methods: A cohort of travel clinic visitors in 2011 was constructed and early one-third of the visitors of each month were reviewed. During the study period, 10,009 visited the travel clinic and a retrospective chart review was performed for 3,332 cases for analysis of travel patterns and prescriptions.

Results: People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV. Overall, most people were traveling to Eastern Africa, South America, and Western Africa, while South-Eastern Asia was the most common destination for the non-YFV group. Besides YFV, the typhoid vaccine was the most commonly prescribed (54.2%), while hepatitis A presented the highest coverage (74.7%) considering the natural immunity, prior and current vaccination history. Additionally, 402 (82.5%) individuals received a prescription for MPM among the 487 individuals travelling to areas with high-risk of malaria infection. Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas.

Conclusion: Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business. For the individuals who are traveling to areas with high-risk for malaria, more proactive approach might be required in case of younger age travelers, longer duration, and travel purpose of providing service to minimize the risk of malaria infection.

Mentions: We first investigated differences between people receiving the YFV as part of their travel consultation visit (N = 2,933) and those without YFV (N = 399). When compared with non-YFV group, YFV group revealed older median age and shorter travel duration. Regarding purpose of travel, business (N = 1,117) and tourism (N = 1,107) were most commonly reported overall; however, providing non-medical service was the most common travel purpose among the non-YFV group followed by business. When comparing the YFV and non-YFV group, business (P = 0.001) and tourism (P < 0.001) were more common among the YFV group while providing non-medical service (P < 0.001) and research or education (P < 0.001) were more common among the non-YFV group. As mentioned before, nearly half of our travel clinic visitors got only YFV. When YFV only group was compared with the group with other prescription besides YFV (YFV in combination), female was more common in YFV only group (P = 0.005) and median age was younger in YFV only group. Regarding the travel purpose, people for business (P < 0.001), providing non-medical service (P = 0.034), and large activity/event (P < 0.001) were more common among YFV in combination group, while tourism (P < 0.001), providing medical service (P < 0.001), and missionary (P = 0.002) were more common purposes among YFV only group. The most frequent travel destinations were Kenya (19.4 %), Tanzania (15.3%) and Brazil (7.6%) in the YFV group while India (15.6%), Peru (15.6%), and Sri Lanka (8.3%) were common in non-YFV group. Regarding destination continent analysis, 2,960 cases were reviewed after excluding 372 cases with multiple continents. In the YFV group, East Africa (43.4%), South America (24.1%), and Western Africa (17.0%) were frequently noted as the visiting continent (Fig. 2). Among non-YFV group, South-Eastern Asia (35.9%), Southern Asia (17.3%), and South America (15.2%) were common destination continents.
