“…HIV surveillance in Sudan in particular has been described to be of good function according to the assessment of the quality of HIV surveillance in low and middle-income countries [ 37 ]. All included studies determined HIV antibodies prevalence range of 0 to 18.3% among different study populations, three studies concluded a prevalence more than 3% - which is the threshold of HIV infection to be considered as high [ 38 ], however, meta-analysis showed overall pooled prevalence of 1%.…”

Viral hepatitis constitutes a global health problem; previous studies have affirmed a considerable morbidity and mortality from both acute infections and chronic complications. On the other hand, Human Immunodeficiency Virus (HIV) infection is also of known burden. Determining prevalence measures of these viruses is crucial for establishing appropriate country specific strategies regarding prevention, diagnosis, and containment. This systematic review was aimed to provide pooled seroprevalence estimates of the three viruses in Sudan. Structured review of the literature was conducted to obtain relevant studies published in both national and international databases. After assessment of quality and bias in all proposed studies, 57 prevalence studies were included. Meta-analysis was conducted for all studies and subgroup analysis was also approached. The total sample size of participants in included studies providing HIV antibodies prevalence was 15,479. Based on information retrieved from these studies, HIV prevalence ranged from 0 to 18.3% among different study populations. However, pooled prevalence estimate for HIV antibodies was 1%. Kassala, Eastern Sudan was the most endemic State (4.18%). The HBV reported seroprevalence rates ranged from 5.1 up to 26.81% among different populations and the overall pooled prevalence was 12.07%. For HCV antibodies; 2.74% was determined to be the pooled prevalence. Khartoum State was the most endemic State of both HBV and HCV with seroprevalence of 12.69% and 6.78%, respectively.Based on data reviewed and synthesized; there is no evidence for an HIV endemic in the general population of Sudan. However, both HBV and HCV seroprevalence rates are indicating otherwise. Reducing the overall burden of HIV, HBV and HCV infections will require new measures and national strategies and the recognition of the infections as one of the country’s priority issues.Electronic supplementary materialThe online version of this article (10.1186/s12985-018-1060-1) contains supplementary material, which is available to authorized users.

“… 25 The geographical coverage of HIV surveillance systems at the beginning of 2000s was adequate only in Morocco while 10 years later Pakistan and Iran, and to some extent Djibouti and Sudan are on the way of achieving almost national HIV surveillance coverage in often challenging political and social environments. 9 …”

“…To assess the quality of HIV surveillance systems we adapted the method developed by WHO and UNAIDS that has been used to evaluate the HIV surveillance systems in low- and middle-income countries since 2002. 9 11 12 We used four parameters to assess the quality of HIV surveillance systems in the MENA countries: timeliness of data collection, appropriateness of populations under surveillance, consistency of the surveillance sites and groups measured over time, and coverage of the surveillance system ( table 1 ).…”

“… 6–8 In an assessment of the quality of HIV surveillance in low- and middle-income countries carried out in 2009, only two countries of the MENA region (Morocco and Sudan) were categorised as having partially functioning HIV surveillance. 9 The need to develop more effective surveillance systems in populations most at risk of HIV was highlighted in a recently conducted comprehensive review of HIV epidemiology in the MENA region. 10 …”

ObjectivesTo provide an overview of the current level of development and results from the national HIV surveillance systems of the 23 countries of the Middle East and North Africa (MENA), and to assess the quality of HIV surveillance systems in the period 2007–2011.MethodsA questionnaire was used to collect the information about the structure, activities and the results of HIV surveillance systems from the National AIDS Programmes. Assessment of the quality was based on four indicators: timeliness of data collection, appropriateness of populations under surveillance, consistency of the surveillance sites and groups measured over time, and coverage of the surveillance system.ResultsOnly in four countries did surveillance systems enable assessment of epidemic trends in the same populations and locations over time, such as in pregnant women (Morocco, Iran), injecting drug users (Iran, Pakistan), female sex workers (Djibouti, Morocco) and male sex workers (Pakistan). There is increasing evidence of HIV infection being firmly established in at least one of the populations most at risk of HIV in nine MENA countries, while lower risk populations show elevated HIV prevalence in South Sudan, Djibouti and some parts of Somalia.ConclusionsThe performance of HIV surveillance systems in several of the MENA countries has improved in recent years. The extent of HIV epidemics in the populations most at risk of HIV is still largely unknown in 10 countries. Multiple data sources that most of the countries still lack would enable indirectly estimation not only of the patterns of HIV epidemics but also the effectiveness of HIV responses.

“…Five papers explain new estimation and modelling methods, assumptions about important parameter values and a description of software tools used in producing the 2009 HIV and AIDS estimates. 4–8 They are followed by a description of the quality of HIV surveillance systems in low and middle income countries as of 2009, 9 a country application of the new estimation software tools for Jamaica, 10 four analytical papers building on the results of the new set of global estimates 11–14 and one on recent surveillance data 15 which together provide insights into the impact of the AIDS epidemic and the effect of treatment and prevention interventions on the course of the epidemic. Finally, two papers look forward to some potential alternative models required to improve ways of modelling prevalence curves as HIV epidemics progress to new states.…”
