This study aimed to summarize uses of available diagnostic techniques through a systematic review and meta-analysis.
Methodology And Principal Findings: We systematically searched the literature and reports comparing two or more diagnostic tests in non-human animals for schistosome infection.
Echinococcosis is a serious zoonotic parasitic disease transmitted from canines to humans and livestock. Periodic deworming is recommended by the WHO/OIE as a highly effective measure against echinococcosis. However, manual deworming involves significant challenges, particularly in remote areas with scarce resources.

Spatial epidemiology is a new branch of epidemiology, and is a subject that mainly analyzes the geographical distribution and changes of population health or diseases and its related impact factors. Recently, spatial epidemiology has been extensively applied in the prevention and control of parasitic diseases in China, and delightful results have been achieved. However, the research and application of theories and methods of spatial epidemiology are still needed to protect the people's health in China.

Objective: To investigate the reasons of natural extinction of snails by comparing the difference of the water chemical properties between the snail-breeding marshland and non-snail marshland in Eastern Dongting Lake areas.
Methods: Three adjoining marshlands in Eastern Dongting Lake areas were selected, one was a snail-breeding marshland, the second was a non-snail marshland, and the third was a boundary zone between them. During the periods of water-rising season, wet season and water-falling season, the water samples from the bottom of 0.

Schistosomiasis is one of the key diseases of surveillance and prevention in China. The elimination of schistosomiasis is of great significance to people's health and social economy. With the development of spatial epidemiology, progress has been made in the spatial distribution of schistosomiasis, the prediction of spatial and temporal trends, and analysis of the environmental factors.

Background: Biomphalaria straminea is an invasive vector in China, posing a significant threat to public health. Understanding the factors affecting the establishment of this snail is crucial to improve our ability to manage its dispersal and potential risk of schistosomiasis transmission. This study sought to determine the spatial distribution of B.

Methods: A block design study was conducted in a Yi county in southwestern China, one of the endemic areas of both HIV/AIDS and in China. All participants were screened for HIV antibodies and antibodies (SjAb) and were classified into four groups: HIV(+)/(-), HIV(-)/ (+), HIV(+)/(+), and HIV(-)/(-).

Objective: To explore the dynamic changes of snail densities in autumn and winter and the relationship between hydrological and meteorological factors and snail growth and decline.
Methods: From Octobers to Decembers of 2007 to 2014, a bottomland close to eastern Dongting Lake was selected as the study field. The snails and elevation of the points were surveyed, and the hydrological and meteorological data were collected.

Objective: To understand the spatial distribution characteristics of wild feces in schistosomiasis endemic areas of Jiangling County, Hubei Province and further explore the source of infection efficiently, so as to provide the evidence for the development of corresponding monitoring and response technology.
Methods: In 2011, the fresh wild feces were investigated every two months in the selected 15 villages by the severity of historical endemic in Jiangling County. The schistosome miracidium hatching method was used to test the schistosome infection of the wild feces.

Objective: To investigate the tempo-spatial patterns of schistosomiasis in Jiangling County, Hubei Province, so as to identify the risk areas and provide the scientific evidence in following intervention plans for marshland epidemic areas in the stage of transmission control.
Methods: The schistosomiasis epidemiological data in Jiangling County from 2009 to 2013 together with the related geographical information were collected and analyzed. The tempo-spatial distribution patterns were analyzed by the spatial autocorrelation analysis and spatial clustering analysis.
Schistosomiasis remains a serious public health issue in many tropical countries, with more than 700 million people at risk of infection. In China, a national integrated control strategy, aiming at blocking its transmission, has been carried out throughout endemic areas since 2005. A longitudinal study was conducted to determine the effects of different intervention measures on the transmission dynamics of S.

Some large-scale hydro projects have resulted in schistosomiasis emergence or re-emergence. Therefore, the dam's potential impact on the transmission of Schistosoma japonicum has raised concerns from medical researchers worldwide.
