Introduction

Cysticercosis is a parasitic disease caused by the larval stage of Taenia solium, the pork tapeworm. Despite being a major health concern in many low- and middle-income countries, it remains relatively overlooked in global health discussions. The disease occurs when humans ingest Taenia solium eggs, which develop into larvae and can form cysts in various tissues, most notably in the brain [1]. Neurocysticercosis, the manifestation of cysticercosis in the central nervous system, is particularly severe and can lead to significant neurological complications, including seizures and cognitive impairment. The global impact of cysticercosis is profound, especially in regions with inadequate sanitation, limited access to healthcare, and high rates of pork consumption. It is prevalent in areas of Latin America, sub-Saharan Africa [2], Southeast Asia, and parts of Eastern Europe, where the life cycle of Taenia solium is facilitated by poor hygiene practices and insufficient meat inspection. The disease contributes significantly to the burden of neurological disorders in these regions, often resulting in chronic health issues and social stigma.

Despite its severity and prevalence, cysticercosis has not received the same level of attention and resources as other infectious diseases. This under-recognition is partly due to the disease's complex presentation and the lack of robust surveillance systems. Furthermore, the economic burden of cysticercosis on affected individuals and healthcare systems is substantial, exacerbating the challenges faced by already vulnerable populations. This review aims to shed light on the global impact of cysticercosis, emphasizing its role as an overlooked health crisis. By examining the disease's epidemiology, clinical manifestations, and the challenges associated with its diagnosis and treatment, this paper seeks to advocate for increased awareness and action [3]. Addressing cysticercosis requires a multifaceted approach, including improved sanitation, enhanced healthcare access, and targeted public health interventions to effectively control and prevent this debilitating disease.

Discussion

Cysticercosis, caused by the larval stage of Taenia solium, is a significant yet frequently under-recognized health issue with a profound impact on affected populations [4]. Its global burden is compounded by a range of factors that perpetuate its prevalence and severity, particularly in resource-limited settings where the disease is most common. Cysticercosis is endemic in regions with inadequate sanitation and high rates of pork consumption, notably in Latin America, sub-Saharan Africa, Southeast Asia, and parts of Eastern Europe. The lack of proper sanitation facilitates the transmission of Taenia solium eggs, which can lead to widespread infection and perpetuate the cycle of the disease. Neurocysticercosis, the most severe form of cysticercosis affecting the central nervous system, is associated with significant neurological symptoms, including seizures, headaches, and cognitive disturbances [5]. This leads to a substantial burden on individuals, families, and healthcare systems, with long-term effects on quality of life and economic productivity.

Diagnosing cysticercosis, particularly neurocysticercosis, can be challenging due to its variable clinical presentation and the need for specialized imaging techniques such as MRI and CT scans [6]. Access to these diagnostic tools is limited in many affected regions, leading to delays in diagnosis and treatment. Treatment typically involves antiparasitic drugs like albendazole or praziquantel, often in conjunction with anti-seizure medications for neurocysticercosis. However, the effectiveness of treatment can be hindered by delays in diagnosis, inadequate healthcare infrastructure, and the potential for drug resistance [7]. Preventing cysticercosis requires a multifaceted approach. Improving sanitation and hygiene practices is crucial in interrupting the transmission cycle of Taenia solium. This includes ensuring proper disposal of human feces and preventing contamination of food and water sources. Additionally, regular deworming of pigs and meat inspection are important for controlling the disease in livestock, which is essential in preventing human infections [8]. Public health campaigns aimed at raising awareness about cysticercosis, improving access to healthcare, and enhancing disease surveillance are vital for controlling and eventually eliminating the disease.

Cysticercosis has historically been overlooked in global health agendas, receiving limited research funding and attention compared to other infectious diseases. There is a critical need for increased research into better diagnostic tools, treatment options, and effective prevention strategies [9]. Additionally, global health initiatives must prioritize cysticercosis to ensure that it receives the attention and resources needed to address this neglected disease effectively. Collaboration between international health organizations, governments, and local communities is essential to improve disease control efforts and reduce the burden of cysticercosis. Addressing the global impact of cysticercosis requires a comprehensive strategy that includes strengthening health systems, improving sanitation, and fostering community engagement [10]. Investing in research and development for new diagnostic and therapeutic tools, as well as scaling up prevention programs, is crucial. Furthermore, enhancing international cooperation and integrating cysticercosis control into broader health initiatives can help mitigate the disease's impact and work towards its elimination.

Conclusion

While significant progress has been made in understanding and managing cysticercosis, it remains an overlooked health crisis with a substantial impact on affected populations. By addressing the challenges in diagnosis, treatment, and prevention, and by prioritizing cysticercosis on the global health agenda, we can work towards reducing its burden and improving health outcomes for vulnerable communities.
