This report is a population-based study describing the pattern of hepatitis C virus (HCV) infection in two distinct regions in Tunisia. The study included a total of 11,507 individuals sampled in 1996 from both genders, all age groups, urban and rural settings belonging to 2,973 families. HCV infection was assessed by commercial enzyme immunoassay (EIA) and immunoblot assays and detection of HCV RNA by PCR. HCV genotypes and subtypes were determined by sequencing in the 5'-untranslated region (UTR) viral genomic region and the INNO-LiPA HCVII genotyping kit. Genetic relatedness between HCV strains was assessed by sequencing of a portion of the NS5B region. HCV prevalence was significantly higher in the North-Western region than in the Southern one: 1.7% versus 0.2% (P < 10(-3), chi(2) = 8,506). There was no difference in positivity according to gender or living in rural or urban settings; the only significant risk factor was advanced age. HCV prevalence among household contacts of HCV positives was not significantly higher than the prevalence in the whole study population. These results indicate a heterogeneity in the geographical distribution of HCV in Tunisia. An increased HCV transmission occurs in the North-Western region with large predominance of genotype 1b (88%) and low contribution of intrafamilial transmission. 相似文献

BackgroundUnder nutrition is a problem of severe magnitude in low income countries like Nigeria. Adolescent school children might also be vulnerable. The dearth of data hinders planning of school health and nutrition programmes for school children.ObjectiveTo determine the prevalence of stunting, thinness; vitamin A and iron deficiencies among adolescent students in Nsukka urban, Nigeria and to determine factors that are associated with these nutritional problems.MethodsA total of 400 participants were randomly selected from 717 students aged 12 – 18 years in 3 randomly selected secondary schools. Questionnaires, anthropometric measurements, and blood analyses were the data collection methods employed.ResultsThe prevalence of stunting was 33.3% and thinness 31.0%. Neither overweight nor obesity was observed. While 64.0% were anaemic; 44.0% had vitamin A deficiency (VAD). A total of 48.0% had both anaemia and stunting, 42% had VAD + thinness; while 40% had anaemia + VAD. Household income was a predictor of vitamin A status. Children from medium/high income households had higher odds of having VAD than those from low income households (AOR=0.14; 95% CI=0.031, 0.607; P=0.009). Household income (AOR=0.12; 95% CI=0.021, 0.671; P=0.016), and age (AOR=0.09; 95% CI=0.014, 0.587; P=0.012) were independent determinants of height-for-age status.ConclusionAmong urban adolescent students in Nigeria, stunting, thinness, anaemia and VAD were problems of public health significance. Age and household monthly income played major roles. 相似文献

Cutaneous leishmaniasis (CL) remains highly endemic in Tunisia. The governorate of Kairouan (Center) is one of the most affected particularly by zoonotic form due to Leishmania major. The purpose of this study was to describe the epidemiological, clinical and therapeutic features of the disease in this governorate and to identify any particularities in children. Three hundred and ninety cases were registered over 2 years (2012 and 2013). The average age was 29 years one month [± 22.7] (34.6% of patients were under 15 years). The cumulative incidence of CL was equal to 34.4 per 100,000 per year. It was higher in children (39.6 per 100,000 versus 29, p=0.004). Cases were diagnosed especially in autumn and winter (88.3% of cases between October and January, p<0.001). The average delay of consultation was one month and 22 days [± 2.5] after onset of lesions. The average number of lesions per patient was 2.7 [± 2.3] with a mean diameter equal to 2.2 cm. In addition to a higher incidence of the disease, two other features were found in “Children” group which are the presence of similar cases in the neighborhood (27.7% versus 13.4%, p=0.002) and preferential localization in the face (36.4% versus 11%) while the members were more affected in adults (63.5% versus 46.4%) (p<0.001). Meglumine antimoniate was prescribed for most of our patients (93.1%). The intramuscular route was used more than local one, probably because of high proportions of multiple lesions and facial localization. 相似文献
