Enfermedades infecciosas importadas asociadas a los desplazamientos internacionales de inmigrantes adultos en visita a familiares y amigos

Has the economic crisis led to a new risk profile for international travellers?

INTRODUCTION

The economic world crisis has led to the migration of European workers to developing countries with a high incidence of infectious diseases. The objective of this study was to assess whether this context has produced an increase in the risks to international travellers for work reasons (TWR).

METHODS

Observational, retrospective study. The study population included TWR who were attended before travelling at an International Health Unit in the year 2007 (the year before the initiation of the European crisis) and in the year 2012 (when the structural crisis was established). A comparative socioeconomic analysis was performed as well as an analysis of the risk factors present in both groups.

RESULTS

In 2007 and 2012 a total of 9,197 travellers were attended. Of these, there were 344 TWR (3.4%); 101 TWR (2.8%) in 2007 and 243 TWR (4.5%) in 2012 (p<0.001). The average age of the travellers was 38.1 years (SD: 10.57). The most common destination was Sub-Saharan Africa, in 164 (47.6%) of the cases. Malaria chemoprophylaxis was prescribed to 152 travellers (44%) and 80 presented comorbidity (23.25%). The TWR from 2012 presented a significantly greater age (p=0.05), more comorbidity (p=0.018) and a greater proportion of stays in rural areas (p=0.0009) for longer time periods (p=0.001).

CONCLUSIONS

At 5 years from the start of the economic crisis, there was a change in the profile of TWR. Their number has increased significantly, as has the proportion who present risk factors for contracting imported diseases. The International Health Units should adapt to these new circumstances and adopt preventive measures for this population.

[Prior health advice to immigrants who travel to visit family and friends]

Objetivo

Los inmigrantes que realizan o proyectan viajes para visitar a sus familiares en sus países de origen (inmigrantes-visiting friends and relatives [I-VFR]) tienen un riesgo superior a adquirir enfermedades relacionadas con el viaje que otros viajeros. El objetivo principal de este estudio es analizar los conocimientos de la población inmigrante sobre la necesidad de recibir consejo sanitario (CS) antes de realizar viajes internacionales en general y, específicamente, antes de viajar a sus países de origen.

Diseño

Estudio observacional y multicéntrico.

Emplazamiento

Participaron 10 médicos de familia de 10 Centros de Salud de Cataluña y Aragón.

Participantes

Quinientos cincuenta y cinco inmigrantes ≥ 15 años de edad, que consultaron a su médico de familia y accedieron a responder un cuestionario. Se realizó un muestreo oportunista.

Resultados

Consideraban necesario recibir CS antes de realizar un viaje internacional 389 (70,1%) personas; 406 (73,2%) eran I-VFR y 145 (35,7%) habían solicitado CS previamente al viaje, con mayor frecuencia a su médico de familia (n = 60; 41,1%).

No habían solicitado CS 261 (65,2%) sujetos, siendo el motivo más frecuente por considerarlo innecesario 173 (42,6%).

Conclusiones

Los I-VFR no suelen solicitar CS previo a viajar, fundamentalmente por considerarlo innecesario. Cuando lo solicitan, con gran frecuencia se dirigen en primera instancia a su médico de familia.

Epidemiologic and biogeographic analysis of 542 VFR traveling children in Catalonia (Spain). A rising new population with specific needs

BACKGROUND

Imported diseases recorded in the European Union (EU) increasingly involve traveling immigrants returning from visits to their relatives and friends (VFR). Children of these immigrant families can represent a population of extreme vulnerability.

METHODS

A randomized cross-sectional study of 698 traveling children under the age of 15 was performed. VFR traveling children and non-VFR (or tourist) children groups were compared.

RESULTS

A total of 698 individuals were analyzed: 354 males (50.7%) and 344 females (49.3%), with a median age (interquartile range) of 4 (2-9) years. Of these, 578 (82.8%) had been born in the EU with 542 (77.7%) being considered as VFR, whereas 156 (22.3%) were considered tourists. VFR children were younger (4.7 vs 8.2 yr; p < 0.001), they had more frequently been born in the EU (62.8% vs 20.1%; p < 0.01) and were more frequently lodged in private homes (76.6% vs 3.2%: p < 0.001) and rural areas (23.2% vs 1.6%; p < 0.001). Furthermore, VFR remained abroad longer (51.6 vs 16.6 d; p < 0.001), the visit/travel time interval was shorter (21.8 vs 32.2 d; p < 0.001) than tourists, and consultation was within 10 days prior to the departure (26.4% vs 2.7%; p < 0.001). The risk factor most differentiating VFR children from tourists was accommodation in a rural setting [odds ratio(OR) = 5.26;95%CI = 2.704-10.262;p < 0.001].

CONCLUSIONS

VFR traveling children showed a greater risk of exposure to infectious diseases compared with tourists. Immigrant families may represent a target group to prioritize international preventive activities.

[Imported and non-imported diseases in the immigrant population. A decade of experience from an infectious diseases unit]

INTRODUCTION

Immigration is an inexorable process. Immigrants may suffer infectious diseases commonly seen in our environment, or those more exotic or more prevalent in their own environment.

MATERIAL AND METHODS

A study was performed including all immigrants see in an Infectious Diseases Unit of a general hospital from June 2001 to May 2010.

RESULTS

We studied 1,071 patients from Latin America (n=405, 37.8%), Northern Africa (n=281, 26.2%), Eastern Europe (n=186, 17.4%), sub-Saharan Africa (n=178, 16.6%), and Asia (21, 2.0%). Transmissible infectious diseases were the leading cause of consultation (53.8%), and they were more common among people coming from Northern Africa (61.6%) and Eastern Europe (69.4%) (P=.001). The second reason for consultation was for common infectious diseases (29%). Tropical infectious diseases were diagnosed in 16.4% of the patients, particularly from sub-Saharan Africa (36%), and Latin America (25.9%) (P<.001). The most common diagnoses were latent tuberculous infection (20.8%) [most common in those from Eastern Europe (27.4%) (P=.004)], respiratory tract infection (12.5%), sexually transmitted infections (10.6%) [most common in patients from Northern Africa (17.1%) (P=.004)], chronic hepatitis (10.4%) [most common in patients from Eastern Europe (26.3%) (P<.001) and sub-Saharan Africa (16.9%) (P=.004)], and active tuberculosis (8.7%) [most common in sub-Saharan Africa patients (15.7%) (P=.001)].

CONCLUSIONS

The spectrum of infectious diseases in the immigrant population in our area is broad, and includes a wide variety of tropical and communicable diseases, but also of common infections. While communicable diseases are the leading cause of consultation, common infections constitute an important part of health care activity.
