Respiratory infections represent the third most frequent health problem for international travelers. The incidence is underestimated mainly because the majority of infections are mild and not incapacitating. Most are due to cosmopolitan agents, and ‘tropical’ and/or geographically restricted infections are rare. The RTI of perhaps the most significance to travelers is influenza. Travelers represent the primary vehicle of the yearly spread of influenza around the globe, and are critical to the global spread of new pandemics. Effective anti-influenza vaccines exist, and all travelers should receive yearly influenza immunization and be instructed in hand-washing and cough/sneeze hygiene. All travelers should also be up to date for other vaccines, including those that prevent RTIs, including measles, pneumococcal diseases, Hib, diphtheria, and pertussis. Clinicians caring for an ill returned traveler with an RTI should characterize the illness as upper or lower tract RTI, and consider the travel itinerary, exposure history, clinical manifestations, incubation period, and host-specific conditions. In the GeoSentinel Surveillance System, women were more likely than men to present with upper respiratory tract infection associated with travel (OR 1.3). Prolonged travel, travel involving visiting friends and relatives, and travel during the northern hemisphere winter increased the odds of being diagnosed with influenza and lower respiratory tract infection rather than upper tract disease in this cohort, and male gender was associated with twofold increased risk odds of pneumonia compared with female gender. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
