RESUMEN
BACKGROUND: Travelers may be responsible for the spread of vaccine-preventable diseases upon return. Travel physicians and family physicians may play a role in checking and updating vaccinations before traveling. Our aim was to evaluate the vaccine coverage for mandatory and recommended vaccination in travelers attending a travel medicine clinic (TMC). METHODS: Vaccine coverage was measured using the current French immunization schedule as reference for correct immunization, in travelers providing a vaccination certificate during the TMC visit (university hospital of Saint-Étienne), between August 1, 2013 and July 31, 2014. RESULTS: In total, 2336 travelers came to the TMC during the study period. Among the 2019 study participants, only 1216 (60.3%) provided a vaccination certificate. Travelers who provided a vaccination certificate were significantly younger than travelers who did not (mean age: 34.8±17.8 vs. 46±18.4 years, P<0.005) and were less likely to be Hajj pilgrims. Vaccine coverage against Tetanus, Diphtheria, and Poliomyelitis (Td/IPV vaccine) was 91.8%, 78.6% against Measles, Mumps, and Rubella (MMR), and 59.4% against Viral Hepatitis B (HBV). BCG vaccine coverage was 71.9%. Older travelers were less likely to be correctly vaccinated, except against HBV as vaccinated travelers were significantly older than unvaccinated travelers. CONCLUSION: Obtaining information about immunization in travelers is difficult. Coverage for routine vaccines should be improved in this population. Travel medicine consultations could be the opportunity to vaccinate against MMR, HBV, and Td/IPV.

OBJECTIVE: The authors had for aim to study the distribution of HIV-1 subtypes in a cohort of HIV-1 positive patients in the University hospital of Saint-Etienne, France, and to describe the epidemiological characteristics of patients infected with a non-B subtype strain. DESIGN: An epidemiological study was made on 271 HIV-1 positive patients followed up in the Infectious Diseases Department over 20 years. All patients sample were subtyped by serotyping and some samples were also tested by genotyping. RESULTS: Two hundred and sixty-four patients (191 men and 73 women) were found infected by an HIV-1 strain belonging to the M group. After combining serotyping and genotyping results, 195 patients were found infected by a B subtype and 69 by a non-B subtype. Most of the latter strains belonged to an A subtype or related ones. The following factors were shown to be linked to an infection by a non-B strain: being born abroad, having contracted the infection though heterosexual practice, and being a woman. The incidence of non-B strains increased regularly over time (to reach more than 40% in 2003). This progression was especially noted for men born in France with risky sexual behaviour. CONCLUSION: These results indicate that more than 40% of HIV-1 new cases detected in the Saint-Etienne area are related to non-B strains and that strains of A and related subtypes are common in the local population with risky sexual behaviour.
