Factors associated with dengue fever IgG sero-prevalence in south Kordofan state, Sudan, in 2012: Reporting prevalence ratios

Dengue fever [DF] is a vector-borne virus transmitted to humans by infected Aedes mosquitoes. In this study, we identified the most important factors associated with the prevalence of IgG antibodies in a border state between Sudan and the new republic of South Sudan. To quantify the association of specific factors with the prevalence of DF IgG antibodies in Lagawa among subjects aged 16-60 years in 2012. Analytical cross-sectional community-based study conducted in Lagawa in 2012. Indoor mosquito breeding was the most significant predictor affecting DF IgG serology. Household water storage was also strongly associated with the presence of IgG antibodies. Residence in urban areas, younger age and a history of travel to the Red Sea State were significant predictors of DF IgG seroprevalence in South Kordofan state. Indoor [household] behaviors associated with DF infection should be modified to mitigate the infection risk in the study area. Awareness should be raised regarding DF in Lagawa to ensure community participation in all control measures, and the surveillance system at the border between Sudan and the republic of South Sudan should be strengthened

Types of haemoglobin in patients attending Khartoum Teaching Hospital - Sudan

Abnormal haemoglobins lead to significant morbidity and mortality. This is a prospective study, evaluating types of haemoglobin and haematological parameters in blood samples of 631 Sudanese patients. Participants were patients who attended different departments in Khartoum Teaching Hospital in the period from March 2005 through July 2005. Electrophoresis was used to determine the type of haemoglobin. 585 cases have normal haemoglobin [Hb A]. Mean red cell indices were: Hbl 1.5 g/dl, PCV 34.9%, MCV 85.4 fl, MCH 32.1pg, MCHC 33.2 g/dl, RDW 37 fl and WBC 7013 /cm3. 46 [7.3%] patients had abnormal Hb. The frequency of Hb types were AA: 92.7%, AS: 4.9%, SS: 0.8%, AC: 0.5% and AF: 0.5%.The presence of abnormal haemoglobin such as haemoglobin S is not unexpected because we live in the centre of an affected area. The study showed low haematological parameters due to various causes including poor nutrition as well as infections and haemolytic processes
