Abstract

Dengue fever is a vector-borne disease; it is transmitted to humans by infected Aedes mosquitoes. In this study, we estimated the prevalence of IgG antibodies in a border oil rich state between Sudan and the new republic of South Sudan, estimated the prevalence of dengue IgG antibodies in Lagawa locality populations age 15 to 60 years in 2012 and described the most affected groups within the locality. This is a cross sectional community-based study with multi-stage cluster sampling technique conducted in 2012. Overall dengue IgG prevalence was found to be 27.7% with 95% confidence interval (CI) (24 to 31%) in Lagawa locality. Dengue looks to be having a burden in South Kordofan state on the top of its current complicated political and geographical contexts. Community awareness regarding dengue fever in the state has to be raised in addition to implementing vector control programs, insuring community participation and sustainability.

Key words: Vector borne disease, communicable diseases, surveillance, South Kordofan.
