Female Genital Schistosomiasis (FGS) Prevalence and Burden Across Endemic Countries, Timelines, and Age Groups: A Retrospective Study.

Female Genital Schistosomiasis (FGS) is caused by Schistosoma haematobium, which causes chronic gynecological conditions that lead to substantial morbidity and infertility. This study's objective is to determine the prevalence and burden of FGS based on the presence of S. haematobium-specific DNA in females across age groups using our previously field-acquired filtered human urine samples from Zambia, Tanzania, and Ghana, collected over multiple years. For Ghana (2013), 39 out of 90 samples were from females, of which 31 (79.5%) were positive and 8 (20.5%) were negative. In Zambia (2016), 80 out of 133 samples were from females, of which 46 (57.5%) tested positive and 34 (42.5%) were negative. For Zambia (2017), 60 out of 110 samples were from females, of which 45 (75%) tested positive and 15 (25%) tested negative. In Tanzania (2018), 70 out of 104 samples were from females, of which 43 (61.4%) tested positive and 27 (38.6%) tested negative. FGS prevalence ranged from 57.5% (Zambia in 2016) to 79.5% (Ghana in 2013) and was found predominantly among the 11–20 years age group. The analytical outcome highlights that FGS is predominant among females in different endemic countries and in the age range of pre-teen to young adult. [ABSTRACT FROM AUTHOR]
