Dengue Fever, Tuberculosis, Human Immunodeficiency Virus, and Hepatitis C Virus Conversion in a Group of Long‐Term Development Aid Workers

摘要: Background Development and humanitarian aid workers are a diverse group of travelers who, because the nature their travel, may have specific travel-related health risks. The main objective this study was to quantify risk dengue fever virus (DFV), tuberculosis (TB), human immunodeficiency (HIV), hepatitis C (HCV) infections in long-term development volunteers. Methods Medical files Volunteer Service Abroad (VSA) volunteers accompanying family/partner/spouse serving over 17 years (1995–2011) were reviewed. Demographics, destination, months spent in-country, and, where available, results pre- post-assignment testing for DFV, TB, HCV HIV extracted. Results Results from 652 assignments audited. Conversion rates calculated when both available. Evidence seroconversion found 6.3% 205 [at rate 3.4 per 1,000 person (pm) on assignment], with Southeast Asia having highest risk. TB during assignment 2.9% 336 converting at 1.4 pm. There no or detected. On questioning, 6.7% reported unprotected sex someone other than regular partner 9.8% potential exposure blood and/or products. Conclusions Infection DFV occurred similar that seen groups travelers, screening would appear be warranted. While none contracted infection, behavior did put them blood- body fluid-borne diseases. It is important pre-assignment travel preparation focuses strategies minimize these
