Toxocariasis is a zoonotic disease that poses a threat to public health worldwide. In the present study, we investigated the seroprevalence of Toxocara infection among primary school children in Henan province, central China, which was previously unknown. Sera from 2451 primary school children were collected from September 2015 to October 2018, and evaluated for anti-Toxocara antibodies by enzyme-linked immunosorbent assay (ELISA). The overall seroprevalence of Toxocara infection was 5.14% (126/2451). The main risk factors related to Toxocara infection identified in this study were the age of children, residence area of children, contact with cats or dogs, and exposure to soil. Hand washing before eating was considered to be a protective factor. These findings demonstrate that Toxocara infection is relatively common among primary school children in Henan province.

Toxoplasma gondii is an obligate intracellular protozoan parasite with global distribution. However, data on T. gondii infection among children in primary school in Henan province, central China were lacking. In this study, 2451 serum samples of primary school children in this province were collected from September 2015 to October 2018 and evaluated for T. gondii antibodies using an enzyme-linked immunosorbent assay (ELISA). The overall seroprevalence was 9.51% (233/2451), of which 7.59% (186/2451) showed IgG positivity, 0.73% (18/2451) IgM and 1.18% (29/2451) both. The main risk factors related to T. gondii infections were the age of children, residence area, contact with cats, and exposure to soil. Moreover, hand washing before eating was considered a protective factor. Seroprevalence of T. gondii infection among the study population was common, emphasizing the need to prevent and control this infection. This is the first report of T. gondii seroprevalence in primary school children in Henan province, central China.

Abstract Objective: The aim of this cross-sectional study was to determine the prevalence, infection intensity and associated risk factors of intestinal schistosomiasis among primary school children in Lira district, Uganda. The study was conducted among 532 primary school pupils aged 6-16 years from eight randomly selected primary schools (March-May 2017). Stool samples were collected and examined for schistosomiasis using Odongo-Aginya method. Data on socio-demographic characteristics and risk factors were obtained using questionnaires. Results: The overall prevalence of Schistosoma mansoni was 35.7% indicating a moderate infection. Both males and females were equally affected with S. mansoni . Ogur sub county had highest prevalence (42.1%) than others. Akangi and Akano primary schools both had highest (21.1%) prevalence compared to the others. Individuals aged 14-16 and 10-14 years had heavy infections (mean epg) of 600 and 565 eggs, respectively than those aged 6-9 years. With regard to risk factors, source of drinking water, sub-county location and primary school were associated with infection. Participants who fetch water from spring (85,44.7%) had higher infection than those who fetch from other sources. The study recommends provision of safe water, periodic treatment of school-aged children with praziquantel and public health education to reduce prevalence of S. mansoni .

This study aimed to determine the frequency of antibodies to Neospora caninum in domestic sheep raised in Henan province, central China. Serum samples from 779 domestic sheep were collected from March 2015 to May 2016, and antibodies to N. caninum were evaluated using an enzyme-linked immunosorbent assay (ELISA). The results showed an overall IgG positive rate of 7.32% (57/779). The risk factors significantly related to seropositivity to N. caninum in sheep were the age, the presence of dogs, and the rearing system. This is the first report of N. caninum infection and associated risk factors in domestic sheep in central China.
