[HIV/AIDS care and international migrations in the rural district of Nanoro, Burkina Faso]. / Prise en charge du VIH/sida et migrations internationales dans le district rural de Nanoro, Burkina Faso.

West African Countries account for almost half of the estimated 20 000 000 international migrants in the continent. In the frame of the scaling up of HAART, our study aims to identify specific features and constraints of access to care for HIV migrant patients returning to Burkina Faso. From January 2007 to August 2011, the Nanoro District Hospital, serving a rural area in the Centre-West of Burkina Faso, followed 437 HIV/AIDS adult patients. Migrants were 139/437 (31.8 %), of whom 108/139 (77.7 %), declared they returned to Burkina Faso to seek care, because the area they migrated to did not offer specific HIV health assistance. At baseline, 113/139 (81,3 %) migrants and 181/298 (60,7 %) residents were in WHO clinical stages III or IV (p< 0.01). For every 100 patients/ year under HAART, 25.5 migrants (91.4 % of whom to foreign countries) and 5.7 Burkina residents were transferred to other centers (p<0.01). 21.8 migrants and 8.5 residents were dead or lost to follow up (p<0.05). For migrant patients, access to HIV screening and care seems to be delayed. The high frequency of migrants under HAART working abroad requires an improved cooperation among the health systems of the African Countries.

Travel-related imported infections in Europe, EuroTravNet 2009.

The aim of this study was to investigate travel-associated morbidity in European travellers in 2009 in comparison with 2008, with a particular emphasis on emerging infectious diseases with the potential for introduction into Europe. Diagnoses with demographic, clinical and travel-related predictors of disease from ill returning travelers presenting to 12 core EuroTravNet sites from January to December 2009 were analysed. A total of 6392 patients were seen at EuroTravNet core sites in 2009, as compared with 6957 in 2008. As compared with 2008, there was a marked increase in the number of travellers exposed in North America and western Europe. Respiratory illnesses, in particular pandemic A(H1N1) influenza, influenza-like syndromes, and tuberculosis, were also observed more frequently. A significant increase in reported dengue cases in 2009 as compared with 2008 was observed (n = 172, 2.7% vs. n = 131, 1.90%) (p 0.002). The numbers of malaria and chikungunya cases were also increasing, although not significantly. Two deaths were recorded: visceral leishmaniasis and sepsis in a Sudanese migrant, and Acinetobacter sp. pneumonia in a patient who had visited Spain. This is the most comprehensive study of travel-related illness in Europe in 2009 as compared with 2008. A significant increase in travel-related respiratory and vector-borne infections was observed, highlighting the potential risk for introduction of these diseases into Europe, where competent vectors are present. The number of traveller deaths is probably underestimated. The possible role of the travellers in the emergence of infectious diseases of public health concern is highlighted.

EuroTravNet: imported Chagas disease in nine European countries, 2008 to 2009.

In recent years, Chagas disease has emerged as a disease of importance outside of endemic areas, largely as a result of migration. In Europe, clinicians may have to treat infected migrants from endemic areas as well as people with acute infections transmitted congenitally,through organ donation or blood transfusion.We describe here the characteristics of patients diagnosed with chronic Chagas disease at the core clinical sites of the EuroTravNet network during 2008 and 2009. Of the 13,349 people who attended the sites, 124 had chronic Chagas disease. Most (96%) were born in Bolivia and the median number of months in the country of residence before visiting a EuroTravNet core site was 38 months (quartile (Q1)­Q3: 26­55). The median age of the patients was 35 years (Q1­Q3: 29­45) and 65% were female. All but one were seen as outpatients and the most frequent reason for consultation was routine screening. Considering that Chagas disease can be transmitted outside endemic regions and that there is effective treatment for some stages of the infection, all migrants from Latin America (excluding the Caribbean) should be questioned about past exposure to the parasite and should undergo serological testing if infection is suspected.

Mother-to-child HIV and HHV-8 transmission in neonates at Saint Camille Medical Centre in Burkina Faso.

In Sub-Saharan Africa, many HIV infected people are co-infected with Human Herpes Virus 8 (HHV-8). Therefore, the present study aimed to: (1) identify the pregnant women co-infected by HIV and HHV-8 at Saint Camille Medical Centre; (2) use three molecules (Zidovudine, Nevirapine and Lamivudine) to interrupt the vertical transmission of HIV and (3) use the PCR technique to diagnose children, who were infected by these viruses, in order to offer them an early medical assistance. A total of 107 pregnant women, aged from 19 to 42 years were diagnosed to be HIV positive at Saint Camille Centre; among them 13 were co-infected with HHV-8. All included women received the HAART. Two to six months after childbirth their babies underwent PCR diagnosis for HIV and HHV-8. The results revealed that, among these mothers, 68.2% were housewives, 34.6% were illiterates and 60.7% did not have university degree. The prevalence of HHV-8 among these pregnant women was 12.15% and the rate of vertical transmission of both HIV and HHV-8, was 0.0%. The issue of this study revealed that the antiretroviral therapy increased the mother CD4 T-cells, prevented the transcription of the mRNA of HHV-8 and blocked HIV vertical transmission.
