RESUMO
BACKGROUND: Pathogenesis of atherosclerosis is complex, and differences between HIV-infected patients and general population cannot be completely explained by the higher prevalence of traditional cardiovascular risk factors. We aimed to analyse the association between inflammation and subclinical atherosclerosis in HIV patients with low Framingham risk score. MATERIALS AND METHODS: Case-control study. SETTING: Outpatient Infectious Diseases clinic in a university hospital. SUBJECTS: HIV-1-infected patients aged > 35 years receiving antiretroviral treatment with viral load < 50 copies/mL and Framingham risk score < 10%. EXCLUSION CRITERIA: inflammatory diseases; dyslipidaemia requiring statins; smoking > 5 cigarettes/day; diabetes; hypertension; vascular diseases. MAIN OUTCOME: subclinical atherosclerosis determined by ultrasonography: common carotid intima-media thickness greater than 0·8 mm or carotid plaque presence. Explanatory variables: ribosomal bacterial DNA (rDNA), sCD14, interleukin-6 (IL-6) and TNF-α. RESULTS: Eighty-four patients were included, 75% male, mean age 42 years and mean CD4+ cells 657 ± 215/mm3 . Median Framingham risk score was 1% at 10 years (percentile 25-75: 0·5-4%). Eighteen patients (21%) had subclinical atherosclerosis; the associated factors were older age (P = 0·001), waist-hip ratio (P = 0·01), time from HIV diagnosis (P = 0·02), rDNA (P = 0·04) and IL-6 (P = 0·01). In multivariate analysis, OR for subclinical atherosclerosis was 7 (95% CI, 1.3-40, P = 0.02) and 9 (95% CI, 1.0-85, P = 0.04) for patients older than 44 years and IL-6 > 6·6 pg/mL, respectively. CONCLUSIONS: Well-controlled HIV patients with low Framingham risk score have a high prevalence of subclinical carotid atherosclerosis, and the main risk factors are age and inflammation. These patients are not receiving primary prophylaxis for cardiovascular events according to current guidelines.

BACKGROUND: Imported malaria is a frequent diagnosis in travellers and migrants. The objective of this study was to describe the epidemiological and clinical characteristics of patients diagnosed with imported malaria within a Spanish collaborative network registering imported diseases (+REDIVI). In addition, the possible association between malaria and type of case, gender, age or area of exposure was explored. METHODS: Cases of imported malaria were identified among all cases registered in the +REDIVI database during the period October 2009-October 2016. Demographic, epidemiological and clinical characteristics were analysed. RESULTS: In total, 11,816 cases of imported infectious diseases were registered in +REDIVI's database between October 2009 and October 2016. Immigrants seen for the first time after migration accounted for 60.2% of cases, 21.0% of patients were travellers, and 18.8% were travellers/immigrants visiting friends and relatives (VFRs). There were 850 cases of malaria (850/11,816, 7.2%). Malaria was significantly more frequent in men than in women (56.8% vs 43.2%) and in VFR-immigrants (52.6%) as compared to travellers (21.3%), immigrants (20.7%) and VFR-travellers (5.4%) (p < 0.001). Although this data was not available for most patients with malaria, only a minority (29/217, 13.4%) mentioned correct anti-malarial prophylaxis. Sub-Saharan Africa was found to be the most common region of acquisition of malaria. Most common reason for consultation after travel was a febrile syndrome although an important proportion of immigrants were asymptomatic and presented only for health screening (27.3%). Around 5% of travellers presented with severe malaria. The most prevalent species of Plasmodium diagnosed was Plasmodium falciparum (81.5%). Malaria due to Plasmodium ovale/Plasmodium vivax was frequent among travellers (17%) and nearly 5% of all malaria cases in immigrants were caused by Plasmodium malariae. CONCLUSIONS: Malaria was among the five most frequent diagnoses registered in +REDIVI's database. Some significant differences were found in the distribution of malaria according to gender, type of case, species. Among all malaria cases, the most frequent diagnosis was P. falciparum infection in VFR-immigrant men.

The population movements during the last decades have resulted in a progressively increasing interest in certain infectious diseases. Eosinophilia is a common finding in immigrants and travellers. One of the most common causes of eosinophilia is helminth infection, and some intestinal protozoa. The aim of this paper is to describe the epidemiological characteristics of cases with eosinophilia and its association with the presence of parasites in the REDIVI data network. This is a multicentre prospective observational study that includes patients diagnosed with eosinophilia registered in the cooperative network for the study of infectious diseases in travellers and immigrants (+REDIVI) from January 2009 to December 2012. A total of 5,255 episodes were recorded in the network during the study period, and eosinophilia was observed in 8.1-31.3% of cases (depending on the immigration group). There were 60.2% men, with a median age of 31years. There were 72.4% immigrants, and 81.2% were asymptomatic. The most commonly identified parasites were S.stercoralis (34.4%), Schistosoma sp. (11.0%), and hookworm (8.6%). The relationship between eosinophilia and parasite infection was significant for all helminths (except for cutaneous larva migrans). The symptoms and duration of the journey did not significantly determine the presence of eosinophilia. In the case of eosinophilia in a person who has lived in helminth endemic areas, it is advisable to carry out targeted studies to diagnose the infection, regardless of immigration type, length of stay, or the presence of symptoms.

INTRODUCTION: The improvement in the prognosis of HIV infection, coupled with the increase in international travel and migration, has led to a rising number of HIV infected travelers. The objective of this study was to describe the epidemiological and clinical features of returning travelers, according to their HIV status. METHODS: An observational prospective study was conducted including travelers and immigrants who traveled to visit friends and relatives (VFRs) registered in the +REDIVI collaborative network (January-2009; October-2014). +REDIVI is a national network that registers information regarding infections imported by travelers and immigrants at 21 different centers using a standardized protocol. RESULTS: A total of 3464 travellers were identified: 72 were HIV+ (2.1%) and 3.392 HIV- (98%). HIV+ vs. HIV- travelers were often older (40.5y vs. 34.2y P=.001), VFRs (79.1% vs. 44.4%; P<.001), and consulted less for pre-travel advice (27% vs. 37%; P=.078). The main destinations for both groups were sub-Saharan Africa and Latin America. The most frequent reasons for consultation after travel were fever, request for a health examination, gastrointestinal complaints, and abnormal laboratory tests (mainly eosinophilia and anemia), which differed between groups. The most frequent diagnoses in HIV+ travelers were malaria (38.8%), newly diagnosed HIV infection (25%), and intestinal parasites (19.4%), while for HIV- travelers the main diagnoses were "healthy" (17.9%), malaria (14%), and intestinal parasites (17.3%). CONCLUSIONS: The typical profile of an HIV+ traveler in +REDIVI was that of a VFR traveler who did not seek pre-travel advice and made high-risk trips. This may increase the chance of acquiring travel-related infections which may pose a special risk for HIV-infected travelers. The post-travel visit was a good opportunity for HIV infection screening.

INTRODUCTION: To determine the infectious diseases (ID) that led to hospital admission of the foreign population>14 years. MATERIAL AND METHODS: A retrospective study of foreign patients admitted to hospital (2000-2012). RESULTS: A total of 3,087 foreigners were admitted with infectious diseases. Of these, 73.6% were from low income countries, and 26.4% from high income countries. Most of them (86.9%) were admitted with common ID, 11.8% with transmissible ID, and 1.6% with tropical ID. Tropical ID and transmissible ID were higher in patients from low income countries (14.7%) than from high income countries (9.7%, p<0.001). The main tropical ID was malaria (74%). The main transmissible ID were tuberculosis (40.3%), hepatitis (27.8%), and HIV/AIDS (27.5%). CONCLUSION: Common ID were the main reason for admission in foreign population.

Current diagnosis of malaria is based on the combined and sequential use of rapid antigen detection tests (RDT) of Plasmodium and subsequent visualization of the parasite stained with Giemsa solution in a thin and thick blood smears. If an expert microscopist is not available, should always be a sensitive RDT to rule out infection by Plasmodium falciparum, output the result immediately and prepare thick smears (air dried) and thin extensions (fixed with methanol) for subsequent staining and review by an expert microscopist. The RDT should be used as an initial screening test, but should not replace microscopy techniques, which should be done in parallel. The diagnosis of malaria should be performed immediately after clinical suspicion. The delay in laboratory diagnosis (greater than 3 hours) should not prevent the initiation of empirical antimalarial treatment if the probability of malaria is high. If the first microscopic examination and RDT are negative, they must be repeated daily in patients with high suspicion. If suspicion remains after three negative results must be sought the opinion of an tropical diseases expert. Genomic amplification methods (PCR) are useful as confirmation of microscopic diagnosis, to characterize mixed infections undetectable by other methods, and to diagnose asymptomatic infections with submicroscopic parasitaemia.

Malaria is a common parasitic disease diagnosed in the returned traveler. Mortality in travelers with imported malaria is around 2-3%, and one of the main factors associated with poor prognosis is the delay in the diagnosis and treatment. Imported malaria cases usually present with fever, headache and myalgia, but other symptoms may appear. The diagnosis should be performed as soon as possible, using thick smear or rapid diagnostic tests, and a blood smear. Treatment should be initiated urgently. In cases of severe malaria, the use of intravenous artemisinins has proved to be superior to intravenous quinine. This document reviews the recommendations of the expert group of the Spanish Society of Tropical Medicine and International Health (SEMTSI) for the diagnosis and treatment of imported malaria in Spain.

BACKGROUND: High-speed global travel, increased trade, world population growth, migration, urbanization and climate change have favoured the emergence and spread of pathogens. We aimed to analyse the evolution of imported infections in Spain during 2012-2022 and the potential impact of some of the abovementioned factors on differential morbidity patterns. METHODS: In this retrospective study (January 2012 to December 2022), we analysed data collected by the +Redivi network across 25 health centres. The network's standardised database records new cases of imported infections, including patient demographics, travel history, pre-travel advice and diagnostic information. To assess outcome rates over time and potential interactions, we constructed penalized weighted models to reduce the bias related to a low event rate and used weighted logistic regression for morbidity outcomes. RESULTS: We recorded 25 632 episodes, comprising 13 913 migrants, 4047 visiting friends and relatives (VFR) immigrants, 392 VFR travellers and 7280 travellers. Most immigrants came from South America (48.3%), Sub-Saharan Africa (28.5%), North Africa (6.6%), South Central Asia (5.4%) and Central America/Caribbean (5.3%). The most common regions visited by travellers were Sub-Saharan Africa (33.5%), South America (24.5%), Central America/Caribbean (13.5%), Southeast Asia (12%) and South Central Asia (10%). The proportion of diagnoses of malaria, strongyloidiasis and unspecified self-limiting febrile syndrome < 3 weeks remained unchanged during the study period. An increased frequency of diagnosis was reported for schistosomiasis, blastocystosis, giardiasis, dengue, diarrhoea, new cases of HIV, latent and pulmonary tuberculosis, whereas a decrease was reported for syphilis, chikungunya fever, Chagas disease and eosinophilia. We detected interactions between time and sex or type of participant across the different diagnoses. CONCLUSIONS: Our study underscores the importance of epidemiological data in understanding infectious diseases dynamics among travellers and migrants, emphasizing how demographic shifts, migration trends and healthcare policies affect disease profiles. Comprehensive data play an essential role in enhancing public health policies and travel advice.

INTRODUCTION: Imported diseases by travellers and immigrants are a priority in the prevention of emerging infectious diseases in the 21st century. There are international records on imported diseases, but no such records are available in Spain. MATERIAL AND METHODS: The cooperative network +Redivi was created in 2009 and consists of 11 national healthcare centres. +Redivi collects demographic data relating to travel/migration and infectious diseases in brief, computerised forms. RESULTS: From January 2009 to October 2011, we collected 4,570 patients and recorded the main demographic data (age, sex, presence of immunosuppression), travel data (destination, duration, time between the return trip and the consultation) and data regarding the migratory process (country of origin, time between the arrival in Spain and the first consultation), as well as preventive measures that have been taken (pre-travel advice, need for malaria chemoprophylaxis, drug that was used and whether it was correct), the reason for coming to the consultation, and final diagnoses of the travellers, immigrants and immigrants-travellers. Likewise, the most frequent diagnoses of asymptomatic patients who came for a check-up are described for each of the three groups. CONCLUSIONS: The +Redivi network allows us to identify and quantify the geographical origin and the type of patients affected, as well as time pattern of infections imported by migrants and travellers. Preliminary data show the significant presence of transmissible diseases and the potential reintroduction in Spain, as well as the importance of systematic screening in patients that came from tropical areas. The objective of +Redivi is to evaluate the impact of imported diseases in Spain in order to contribute to improving the care of patients, to have an influence on prevention and treatment of the most prevalent imported diseases, and to detect possible outbreaks.

INTRODUCTION: The COVID-19 pandemic has caused disruptions in prevention and management strategies for malaria globally. Currently, data analysing trends in travel-related infections during the pandemic years are scarce. The objective of this analysis was to describe the epidemiological and clinical characteristics of patients with imported malaria within the +Redivi network in Spain, focusing on yearly trends from pre-pandemic years to date. METHODS: Cases recorded in +Redivi from October 2009 to December 2021 were analysed and patients with a diagnosis of malaria (standard diagnostic methods using thick/thin peripheral blood smears, with/without a malaria rapid diagnostic test and/or Plasmodium spp. polymerase chain reaction) were identified. The total number of malaria cases, cases according to type of patient and severe cases, per year, were analysed. RESULTS: In total, 1751 cases of malaria (1751/26 601, 6.6%) were identified. The majority occurred in males (1041, 59.5%), median age was 36.3 (interquartile range: 27-44.7) years and most occurred in visiting friends and relatives (VFR)-immigrants (872, 49.8%). Most infections were acquired in sub-Saharan Africa (1.660, 94.8%) and were due to Plasmodium falciparum (81.3%). There were 64 cases of severe malaria (3.7%) and 4 patients died (0.2% mortality, all in pre-pandemic years). A significant increase in cases of severe malaria was observed during the study period (P < 0.001) (attributable to the increase in 2021). There were 16/93 severe cases in 2021 (17.2%), all due to Plasmodium falciparum, (compared with ≤ 5% in previous years), which mainly occurred in travellers and VFR-immigrants (10/16, 62.5% and 5/16, 31.3%, respectively). CONCLUSIONS: After an initial decline associated with travel restrictions due to the ongoing COVID-19 pandemic, an increase in imported malaria and a significant increase in cases of severe malaria was observed. Patients with imported malaria may present and/or be diagnosed late during this public health crisis and health care professionals should be alerted to the recent increase in severe cases.

As a result of population migration, Chagas disease is no longer limited to the North and South American continents. In HIV-infected patients, chronic infection by Trypanosoma cruzi behaves as an opportunistic infection in severely immunosuppressed patients and is responsible for high morbidity and mortality. Unlike other opportunistic infections, information on the natural history, diagnosis, treatment, and prevention of Chagas disease is scarce. Spain has the highest number of cases of Chagas disease outside the North and South American continents, and coinfection with HIV is increasingly prevalent. In this article, the Spanish Society for Tropical Medicine and International Health (Sociedad Española de Medicina Tropical y Salud Internacional) reviews the current situation of coinfection with HIV and T. cruzi infection and provides guidelines on the diagnosis, treatment, and prevention in areas where Chagas disease is not endemic. It also identifies areas of uncertainty where additional research is necessary.

Exploring differences in clinical outcomes based on race and origin among patients hospitalized for COVID-19 is a controversial issue. The ALC COVID-19 Registry includes all confirmed COVID-19 patients admitted to hospital from 3 March 2020 to 17 December 2020. The data were obtained from electronic health records in order to evaluate the differences in the clinical features and outcomes among European and Latin American patients. The follow-ups occurred after 156 days. A propensity score weighting (PSW) logistic regression model was used to estimate the odds ratio (OR, 95% CI) for Latin American origin and outcome associations. Of the 696 patients included, 46.7% were women, with a median age of 65 (IQR 53-67) years, 614 (88.2%) were European, and 82 (11.8%) were Latin American. Latin American patients were younger, with fewer comorbidities, and a higher incidence of extensive pneumonia. After adjusting for residual confounders, Latin American origin was not associated with an increased risk of death (PSW OR 0.85 (0.23-3.14)) or with the need for invasive mechanical ventilation (PSW OR 0.35 (0.12-1.03)). Latin American origin was associated with a shorter hospital stay, but without differences in how long the patient remained on mechanical ventilation. In a public healthcare system, the rates of death or mechanical ventilation in severe COVID-19 cases were found to be comparable between patients of European and Latin American origins.
RESUMO
HIV remains a major cause of morbidity and mortality for people living in many low-income countries. With an HIV prevalence of 12.4% among people aged over 15 years, Mozambique was ranked in 2019 as one of eight countries with the highest HIV rates in the world. We analyzed routinely collected data from electronical medical records in HIV-infected patients aged 15 years or older and enrolled at Carmelo Hospital of Chokwe in Chokwe from 2002 to 2019. Attrition was defined as individuals who were either reported dead or lost to follow-up (LTFU) (≥ 90 days since the last clinic visit with missed medical pick-up after 3 days of failed calls). Kaplan-Meier survival curves and Cox regression analyses were used to model the incidence and predictors of time to attrition. From January 2002 to December 2019, 16,321 patients were enrolled on antiretroviral therapy (ART): 59.2% were women, and 37.9% were aged 25-34 years old. At the time of the analysis, 7279 (44.6%) were active and on ART. Overall, the 16,321 adults on ART contributed a total of 72,987 person-years of observation. The overall attrition rate was 9.46 per 100 person-years. Cox regression showed a higher risk of attrition in those following an inpatient regimen (hazard ratio [HR] 3.18, 95% confidence interval [CI] 2.89-3.50; p < 0.001), having CD4 counts under 50 cells/µL (HR 1.91, 95% CI 1.63-2.24, p < 0.001), receiving anti-TB treatment within 90 days of ART initiation (HR 6.53, 95% CI 5.72-7.45; p < 0.001), classified as WHO clinical stage III (HR 3.75, 95% CI 3.21-4.37; p < 0.001), and having Kaposi's sarcoma (HR 1.99, 95% CI 1.65-2.39, p < 0.001). Kaplan-Meier analysis showed that patients with CD4 counts of less than 50 cells/µL on ART initiation had a 40% lower chance of survival at 18 years. Low CD4 cell counts, ART initiation as an inpatient, WHO clinical stage III, and anti-tuberculosis treatment within 90 days of ART initiation were strongly associated with attrition. Strengthening HIV testing and ART treatment, improving the diagnosis of tuberculosis before ART initiation, and guaranteed psychosocial support systems are the best tools to reduce patient attrition after starting ART.

The aim of this study was to describe the clinical and epidemiological profile of immunosuppressed patients with imported strongyloidiasis in a non-endemic setting, and to compare these results with non-immunosuppressed patients. This is a case-control substudy from a larger observational retrospective study that included all patients with strongyloidiasis registered in the +REDIVI Spanish Collaborative Network. Overall, 1245 patients with imported strongyloidiasis were included. From these, 80 (6.4%) patients had some kind of immunosuppression. Three (3.8%) patients had a hyperinfection syndrome, and 34 (52.3%) patients had eosinophilia. The percentages of positive results of the formalin-ether technique, the fecal culture and serology were 12.3%, 21.1% and 95.4%, respectively. When comparing the main characteristics, immunosuppressed patients had higher proportion of severe clinical manifestations and lower proportion of eosinophilia. No differences were found regarding yield of microbiological techniques and treatment response. These results stress the importance of strongyloidiasis screening among immunosuppressed patients coming from endemic areas. Serological tests have an acceptable sensitivity to be used as a screening tool.

The aim of the study was to evaluate the availability of different procedures, diagnostic tests, and treatments, as well as the procedures and techniques used in the management of cystic echinococcosis (CE) in Spain. This was a cross-sectional study performed from September to December 2018 in Spain. A survey directed to CE-treating clinicians was conducted to collect information regarding the center characteristics and the different protocols of management followed. Thirty-nine centers among 76 contacted centers participated in the survey, most of them belonging to the public health system and attending both adult and children. The median number of patients with CE attended during the last three years per center was 15. Percutaneous techniques were used only in seven centers, and surgery was the most frequently used therapeutic approach. Drugs and duration of treatment (both when administered exclusively or when combined with surgery/puncture, aspiration, injection, and reaspiration) were very variable depending on the centers. There is a high variability in the management of CE among Spanish centers. These results stress the importance of promoting the diffusion of existing knowledge, adapting the WHO recommendations to our setting, and referring patients to referral centers at a national level.

BACKGROUND: Tuberculosis (TB) is the leading cause of infectious disease mortality worldwide. We analysed active and latent TB infections (LTBI) from the Spanish Network for the Study of Imported Infectious Diseases by Travellers and Immigrants (+REDIVI). METHODS: Observational, retrospective, multicentre study of TB and LTBI registered in the +REDIVI network from October 2009 to December 2016. RESULTS: Of 1008 cases of LTBI, 884 (87.7%) were immigrants; 93 (4.5%), immigrants visiting friends and relatives (VFR); 2 (0.9%), VFR-travellers; and 29 (1.1%), travellers. Absolute (Nâ¯=â¯157 vs. Nâ¯=â¯75) and relative (12.5% vs. 5.9%) frequency decreased over the study period (pâ¯=â¯0.003). Median time to diagnosis was 24.6 months (females 50.3 vs males 11.9; pâ¯<â¯0.001). Of 448â¯TB cases, 405 (90.4%) were in immigrants; 30 (6.7%), VFR-immigrants; 6 (1.3%), VFR-travellers; and 7 (1.6%), travellers. Median time to diagnosis was 62.5 months (females 86.6 vs males 70.1; pâ¯=â¯0.0075). There were 8 multidrug resistant TB cases and 1 extensively drug resistant case of TB, all in immigrants. CONCLUSION: TB was frequently diagnosed more than 5 years after arrival in Spain. Screening programmes for TB and LTBI in immigrants should be considered beyond this time point. Women showed a higher diagnostic delay for both latent and active TB.

BACKGROUND: Neurocysticercosis (NCC) is the most common parasitic neurological disease worldwide and a major cause of epilepsy. Spain is the country reporting the highest number of NCC imported cases in Europe. METHODOLOGY: Retrospective case series of NCC patients registered in the +REDIVI Network from October 1, 2009 to July 2018. A specific questionnaire, including clinical and diagnostic characteristics, was created and sent to the collaborator centers. RESULTS: 46 cases were included in the analysis. 55% were male, mean age of 40 years. 95.6% were migrants. The median duration since migration from an endemic area was 10 years. Predominant nationalities were Ecuadorians (50%) and Bolivians (30.4%). Frequent locations were parenchymal (87%), subarachnoid (26.1%) and intraventricular cysts (10.9%). Serological analysis was performed in 91.3%, being 54.8% positive. Most prevalent clinical manifestations were persistent headache (60.9%), epilepsy (43.5%) and visual changes (13%). Patients were mainly treated with albendazole (76.1%), corticosteroids (67.4%), and anticonvulsionants (52.2%). 82.5% had a favorable clinical outcome. CONCLUSIONS: Most NCC cases were long-standing migrants. Few clinical differences were observed depending on the cysticerci location. The treatment was often not according to current recommendations, and no uniform criteria were followed when it came to the therapeutic regimen. NCC case management in Spain (including clinician awareness and laboratory capacity improvements) needs to be strengthened.

BACKGROUND: Imported strongyloidiasis is increasingly being diagnosed in non-endemic areas. The aim of this study was to describe the epidemiological, clinical and microbiological characteristics of patients with imported strongyloidiasis in Spain. METHODOLOGY: This is an observational retrospective study that included all patients diagnosed of strongyloidiasis registered in the +REDIVI Collaborative Network from 2009 to 2017. Demographic, epidemiological and clinical information was collected from the +REDIVI database, and extra information regarding microbiological techniques, treatment and follow-up was requested to participant centers. FINDINGS: Overall, 1245 cases were included. Most of them were immigrants (66.9%), and South America was the most frequent area of origin. Detection of larvae in stool samples was observed in 21.9% of the patients, and serological tests allowed making the diagnosis in the rest of the cases. Eosinophilia was present in 82.2% of cases. Treatment with ivermectin (compared with albendazole) was the most strongly associated factor to achieve the cure (OR 2.34). CONCLUSIONS: Given the long latency of the infection and the risk of developing a severe presentation, screening of S. stercoralis infection should be mandatory in patients coming from or had traveling to endemic areas, especially in those with immunosuppressant conditions.

BACKGROUND: Continuous growth of mobile populations has influenced the global epidemiology of infectious diseases, including chronic and acute viral hepatitis. METHOD: A prospective observational multicentre study was performed in a Spanish network of imported infections. Viral hepatitis cases from January 2009 to September 2017 were included. RESULTS: Of 14,546 records, 723 (4.97%) had imported viral hepatitis, including 48 (6.64%) acute cases and 675 (93.36%) chronic cases. Of the 48 acute cases, 31 were travellers and immigrants returning from visiting friends or relatives (VFR), while 19 (61%) were acute Hepatitis A or Hepatitis B. Only 18.2% of VFR immigrants and 35% of travellers received pre-travel advice. Acute hepatitis was more frequent in VFR immigrants (AOR 2.59, CI95% 1.20-5.60) and travellers (AOR 2.83, CI95% 1.46-5.50) than immigrants. Of the 675 Chronic cases, 570 were immigrants, and 439 (77%) had chronic Hepatitis B. Chronic hepatitis was more frequent in immigrants (AOR 20.22, CI95% 11.64-35.13) and VFR immigrants (AOR 11.12, CI95% 6.20-19.94) than travellers. CONCLUSIONS: Chronic viral hepatitis was typical of immigrants, acute viral hepatitis was common among travellers, and VFR immigrants had mixed risk. Improving pre-travel consultation and screening of immigrants may contribute to preventing new cases of viral hepatitis and avoiding community transmission.
