Echocardiographic surveillance of rheumatic heart disease in West and North Darfur compared with Kassala State: socioeconomic or genetic differences?

Rheumatic heart disease (RHD), a preventable complication of group A beta-haemolytic streptococcal infection, is highly prevalent in Sudan. Echocardiographic (echo) screening has an established role in disease surveillance. This study aims to measure the echo prevalence of RHD using handheld echo (HHE) in West and North Darfur and Kassala states and initiate control programs.
