“…The epidemiologic pattern of HAV in a given country is therefore deduced primarily from seroprevalence data (Letaief et al 2005). In Tunisia, a number of studies found HAV prevalence rates ranging between 84.0 and 92 %; recently, a survey conducted to assess the prevalence of HAV among Tunisian children and adolescents revealed an overall seroprevalence of 60 % in this population (44 %, in children\10 years old, 58 % in those 10-15 years of age, and 83 % in adolescents with [15 years of age) (Kamal et al 2010). These data suggest that HAV endemicity in Tunisia has changed from high to intermediate/high.…”

Qualitative and Quantitative Assessment of Hepatitis A Virus in Wastewaters in Tunisia

Hepatitis A causes substantial morbidity in both industrialized and non-industrialized countries and represents an important health problem in several southern Mediterranean countries. The objectives of the study were as follows: (a) to assess the occurrence of hepatitis A virus (HAV) in Tunisia through the monitoring of urban wastewaters collected at wastewater treatment plants (WTPs); (b) to characterize environmental strains; and (c) to estimate the viral load in raw and treated sewages, in order to evaluate the potential impact on superficial waters receiving discharges. A total of 150 raw and treated wastewaters were collected from three WTPs and analyzed by both qualitative (RT-PCR/nested) and quantitative (qRT-PCR) methods. Of these, 100 (66%) were found to be positive for HAV by the qualitative assay: 68.3% in influents and 64.7% in effluents. The vast majority of HAV sequences belonged to sub-genotype IA, with 11 different strains detected found to be identical to clinical strains isolated from Tunisian patients with acute hepatitis. Five unique variants were also detected, not previously reported in clinical cases. Only two IB strains were found, confirming the rarity of this sub-genotype in this country. The results of the present study indicate a wide circulation of the pathogen in the population, most probably in the form of asymptomatic infections, a finding consistent with the classification of the country as having intermediate/high endemicity. Quantitative data showed high viral loads in influents (3.5E+05 genome copies/liter, mean value) as well as effluents (2.5E+05 genome copies/liter, mean value), suggesting that contaminated water could be a critical element in transmission.

“…Therefore, further studies are needed to determine the prevalence of HBV among the general population. The small number of subjects included in the studies we referred to might explain this variation; thus, larger more detailed studies are needed to gather reliable data [33][34][35][36].…”

Introduction: The epidemiology of viral hepatitis during pregnancy is of paramount importance for health planners and program managers. Data on viral hepatitis during pregnancy are not readily available in many African and Arab countries. Both regions have their own unique geography, and comprise over 59 states with crossover and interaction of different cultures. Methodology: A systematic electronic search of the published literature was conducted and data on epidemiology and risk factors of maternal hepatitis B virus (HBV) infection and hepatitis C (HCV) infection in Arab and African countries were extracted from relevant studies. Results: The serology of hepatitis viruses varies greatly among these countries, with different viral genotype patterns. Such a variation in prevalence could be explained by the different risk factors involved. Sexual contact, perinatal infection, blood and its derivatives, hemodialysis, intravenous and percutaneous drug use, and occupational, habitual, and social behavior have been identified as risk factors for hepatitis transmission in various settings in these countries. Conclusions: Infection from hepatitis B and C viruses imposes major socioeconomic and even political burdens on such young and dynamic societies. Thus strategies and clear policies of intervention are required to combat the consequences of hepatitis B and C at both the regional and national levels.
