Human giardiasis poses a significant public health challenge globally, particularly in resource-limited countries due to poor personal hygiene, environmental sanitation, and unsafe water. It affects approximately 300 million people globally every year, and children are the most at-risk population. This scoping review assesses the burden, transmission dynamics, and public health implications of human giardiasis in Ghana.
A comprehensive search strategy across PubMed, African Journals Online, Science Direct, Scopus and Web of Science databases using key terms "Giardia duodenalis," "Giardia intestinalis," and "Giardiasis." Published articles on Human giardiasis in Ghana between 2004 and 2024 on epidemiology, prevalence, diagnostic methods, and target populations were extracted.
Seventeen studies conducted in Ghana met the inclusion criteria and were included in this review. The prevalence of in Ghana varies significantly across studies and settings, with rates ranging from 0.7% to 59.6%, with children being the most affected. However, studies conducted in Ghana since 2020 indicate a lower prevalence, with rates between 0.7% and 13.0%. Regional studies indicate varied prevalence: 0.7%-13.0%, 2.3%-59.6%, and 5.9% in the Southern, Middle, and Northern belts, respectively.
The prevalence of human giardiasis in Ghana is relatively low. However, targeted public health interventions are necessary to maintain the progress achieved, in addition to improvements in sanitation and hygiene practices.
人体贾第虫病在全球范围内构成了重大的公共卫生挑战，尤其是在资源有限的国家，因为个人卫生、环境卫生和不安全饮水状况较差。全球每年约有3亿人受其影响，儿童是风险最高的人群。本综述评估了加纳人体贾第虫病的负担、传播动态及公共卫生影响。
通过在PubMed、非洲期刊在线、科学Direct、Scopus和科学网数据库中使用关键词“十二指肠贾第虫”“肠贾第虫”和“贾第虫病”进行全面检索。提取了2004年至2024年期间发表的关于加纳人体贾第虫病的流行病学、患病率、诊断方法和目标人群的文章。
在加纳进行的17项研究符合纳入标准并被纳入本综述。加纳的患病率在不同研究和环境中差异显著，范围从0.7%到59.6%，儿童受影响最大。然而，2020年以来在加纳进行的研究表明患病率较低，在0.7%至13.0%之间。区域研究表明患病率各不相同：南部、中部和北部地区分别为0.7%-13.0%、2.3%-59.6%和5.9%。
加纳人体贾第虫病的患病率相对较低。然而，除了改善卫生和卫生习惯外，还需要有针对性的公共卫生干预措施来维持已取得的进展。
