Insights
Enterobius vermicularis, or pinworm infection, in Chinese children declined 32% from 2016-2020. This common childhood infection showed spatial clustering in southern China, highlighting areas needing targeted control efforts.
Area of Science:
- Parasitology
- Epidemiology
- Pediatric Health
Background:
- Enterobius vermicularis infection poses a significant public health concern in China, particularly impacting children.
- Understanding the infection's prevalence and trends is crucial for effective disease control and promoting child well-being.
Purpose of the Study:
- To analyze the epidemiological status and trends of Enterobius vermicularis infection in Chinese children from 2016 to 2020.
- To investigate the spatial distribution and temporal clustering patterns of the infection.
Main Methods:
- Descriptive epidemiological analysis was employed to assess infection rates and trends.
- Spatial autocorrelation and spatio-temporal scanning analyses were used to identify geographical hotspots and clustering.
Main Results:
- A fluctuating downward trend in Enterobius vermicularis infection was observed, with a 32% decrease by 2020 compared to 2016.
- Infection rates were highest among 4-, 5-, and 6-year-old children, with no significant gender-based differences.
- Geographical hotspots and spatial clustering were predominantly identified in southern China.
Conclusions:
- Enterobius vermicularis infection rates in Chinese children (3-9 years) decreased between 2016-2020, exhibiting spatial clustering primarily in southern regions.
- Strengthened surveillance, targeted control measures, health education, and environmental improvements are recommended for southern China.
Abstract:
(1) Background: Enterobius vermicularis infection causes a significant health burden in children. The infection occurs throughout the country and remains a serious public concern in China. Therefore, it is necessary to know the situation of E. vermicularis infection, to provide a scientific basis for the disease control and the optimum conditions for children's growth. (2) Methods: Descriptive epidemiological analysis was implemented to demonstrate the status and changing trend of E. vermicularis infection from 2016 to 2020, while the spatial distribution characteristics and spatial-temporal clustering were illuminated by spatial autocorrelation analysis and spatio-temporal scanning analysis. (3) Results: The infection of E. vermicularis showed a fluctuating downward trend with a decline of 32.00% in 2020 compared to that in 2016 and was concentrated in central and southern China. There was no significant difference in infection rate between boys and girls, while the high infection rate was presented in 4-, 5- and 6- year-old children. The hotspots and spatial clustering areas were mainly concentrated in southern China. (4) Conclusions: From 2016 to 2020, the infection rate of E. vermicularis in children aged 3 to 9 years in China demonstrated a declining trend, and its distribution showed spatial clustering, mainly in southern China. Therefore, it is necessary to strengthen surveillance and implement control measures in combination with health education and environmental improvement.
