Schistosimiasis affects over 250 million people globally. It is considered a moderately endemic condition in South Africa, with 36 people per 100 000 infected annually between 2011 and 2018. Despite its ability to cause long-term complications, it remains under-studied in Gauteng Province, and its epidemiological patterns are poorly understood.
To describe the prevalence and trends of human schistosomiasis from 2017 to 2022.
Gauteng Province, South Africa.
A descriptive cross-sectional study was conducted using all clinical and laboratory human schistosomiasis cases in Gauteng Province from 2017 to 2022. Descriptive statistics summarised cases. Annual trends, seasonal patterns, and geographic distribution were assessed. Yearly incidence rates and overall provincial prevalence were estimated per 100 000 population.
There were 2526 human schistosomiasis cases recorded. The median age was 28 years (interquartile range [IQR]: 19-42), and men aged 10-19 years were most affected (15%). Cases declined by 37 per year over the study period, with seasonal peaks in February-March and August-September. The highest incidence occurred in 2019 (3.83 cases per 100 000). City of Tshwane Metropolitan and Mogale City had region-specific prevalence of > 25 cases per 100 000; overall provincial prevalence was 15 cases per 100 000.
Enhanced surveillance, strengthened reporting, targeted awareness and preventative measures in vulnerable communities are recommended to reduce transmission. Ongoing research is crucial to inform evidence-based interventions in Gauteng Province and South Africa.
The study identified key demographic patterns, geographic hotspots, and temporal trends of human schistosomiasis cases in Gauteng Province.
全球有超过2.5亿人感染血吸虫病。在南非，血吸虫病被视为一种中度流行疾病，2011年至2018年期间，每年每10万人中有36人感染。尽管它能够引发长期并发症，但在豪登省，对其研究仍然不足，人们对其流行模式了解甚少。
描述2017年至2022年期间人类血吸虫病的患病率和趋势。
南非豪登省。
采用描述性横断面研究，纳入2017年至2022年豪登省所有临床和实验室确诊的人类血吸虫病病例。描述性统计总结病例情况。评估年度趋势、季节性模式和地理分布。按每10万人估计年发病率和全省总体患病率。
共记录了2526例人类血吸虫病病例。中位年龄为28岁（四分位间距[IQR]：19 - 42岁），10至19岁男性受影响最为严重（15%）。在研究期间，病例数每年下降37例，2月至3月和8月至9月出现季节性高峰。2019年发病率最高（每10万人3.83例）。茨瓦内都市市和莫加莱市特定区域的患病率>每10万人25例；全省总体患病率为每10万人15例。
建议加强监测、强化报告、在脆弱社区开展有针对性的宣传和预防措施以减少传播。持续开展研究对于为豪登省和南非基于证据的干预措施提供信息至关重要。
该研究确定了豪登省人类血吸虫病病例的关键人口统计学模式、地理热点和时间趋势。
