Background Cysticercosis is spreading all over the world and it is a major health problem in most countries of Latin America, Africa, and Asia. Extensive disseminated cysticercosis is relatively rare and fewer than 120 case have been reported in the worldwide. We reported a rare case of extensive disseminated cysticercosis in Yunan province, China. Case presentation A rare case of extensive disseminated cysticercosis, in a 61-year-old male Chinese was detected from Yunnan province in 2018. Clinical and etiological examination was performed, as well as the epidemiological investigation. Conclusion The life cycle of T. solium in the area where the case came from is complete. We expect this case could raise the attentions to the control of Taenia solium infection and subsequent cysticercosis there.

Cysticercosis remains a public health problem in China, with disease prevalence attributed to poor socio-economic and public health conditions. This parasitic food-borne disease was prioritized for effective control following implementation of the national surveys on parasitic diseases carried out in China. We predicted the cysticercosis distribution in Dali, Yunnan Province by assessing spatio-temporal distribution characteristics between 2000 and 2014 to better understand the trend of the disease incidence. A database of cysticercosis cases was provided by the clinical department at the Dali Prefectural Institute of Research and Control of Schistosomiasis. Describing the epidemiological features of cysticercosis and analyzing its spatiotemporal distribution of cases using mapping, scanning and spatial autocorrelation analysis, our findings found a total of 3,347 patients with cysticercosis infection, neurocysticercosis in particular. Cysticercosis prevalence was the highest among young and middle-aged male farmers, and also predominant among the Bai nationality. Three aggregation areas were identified during the period 2000-2014. Hotspot analysis implicated Dali City, Eryuan County and Yangbi County between 2000 and 2007, with areas gradually shifting towards the western and northern parts of the province. The hotspot map indicated that Eryuan County was a constant problem with respect to cysticercosis. The results indicated three cysticercosis clusters in Dali that could be attributed to environmental factors and unhealthy lifestyles. Multi-sectoral control initiatives are, therefore, recommended in these areas to effectively control and prevent cysticercosis among the population.

What is already known about this topic? Neurocysticercosis is the most severe form of infection caused by ingesting cysticerci, the larval cysts of the pork tapeworm, Taenia solium. Approximately 50 million people worldwide have neurocysticercosis, which is the leading cause of acquired epilepsy in many endemic countries. What is added by this report? The health of neurocysticercosis patients can be seriously impaired, including through loss of mobility, inability to do self-care, impairment of usual activities, pain/discomfort, anxiety/depression, and impaired cognition. Cognitive impairment is the major consequence of neurocysticercosis and significant contributor to decreased health-related quality of life. Our study made the first estimate of disability weight from neurocysticercosis as a key parameter for disease burden assessment in China. What are the implications for public health practice? To prevent severe health outcomes from neurocysticercosis in China, it is necessary to improve public awareness of neurocysticercosis and relevant health behaviors.
