Short-Term Impacts of Meteorology, Air Pollution, and Internet Search Data on Viral Diarrhea Infection among Children in Jilin Province, China.

ABSTRACT: The influence of natural environmental factors and social factors on children's viral diarrhea remains inconclusive. This study aimed to evaluate the short-term effects of temperature, precipitation, air quality, and social attention on children's viral diarrhea in temperate regions of China by using the distribution lag nonlinear model (DLNM). We found that low temperature affected the increase in children's viral diarrhea infection for about 1 week, while high temperature and heavy precipitation affected the increase in children's viral diarrhea infection risk for at least 3 weeks. As the increase of the air pollution index may change the daily life of the public, the infection of children's viral diarrhea can be restrained within 10 days, but the risk of infection will increase after 2 weeks. The extreme network search may reflect the local outbreak of viral diarrhea, which will significantly improve the infection risk. The above factors can help the departments of epidemic prevention and control create early warnings of high-risk outbreaks in time and assist the public to deal with the outbreak of children's viral diarrhea.

Project description:Global climate change is causing notable shifts in the environmental suitability of the main regions involved in potato cultivation and has, thus, changed the production potential of potatoes. These shifts can be mapped at fine scales to better understand climate change within areas of potato cultivation and to find infrastructural- and breeding-based solutions. As a case study, we have identified and mapped the structural and spatial shifts that occurred in areas suitable for potato cultivation in Jilin Province, China. We identified a discontinuity in climate change trends between 1961 and 2018 based on data for Jilin Province, and analyzed the averages and linear trends for six important climatic parameters. We used the averages of these climatic parameters to establish climate models for the province and determined cultivation using a multi-criteria, decision-based model that integrates Analytical Hierarchy Process Weighted Principal Component Analysis (AHP-PCA) and Geographic Information System (GIS). We mapped the environmentally suitable areas for potato cultivation at a 3-km resolution based on the geo-climate model for each time period and analyzed differences between them. We found that "Most suitable" areas for potato cultivation were mainly distributed in the central area of Jilin Province, "Suitable" areas were located in the northwestern plains, and "Sub-suitable" areas were located in the eastern mountainous areas. In contrast, "Not suitable" areas occur mainly in the high-altitude areas in the east. The areas of "Most suitable" and "Suitable" areas for potato cultivation in Jilin Province were increasing, with increasing rates of 0.37 × 1,000 km2 decade-1 (R2 = 0.58, P < 0.01) and 0.20 × 1,000 km2 decade-1 (R2 = 0.28, P < 0.01), respectively, while the extent of "Sub-suitable" areas is decreasing, with a decreasing rate of 0.58 × 1,000 km2 decade-1 (R2 = 0.53, P < 0.05). The area of "Not suitable" areas had undergone little change. "Most suitable" and "Suitable" areas for potato cultivation showed a trend towards northward expansion. Overall, our results suggest that global climate change has had a positive impact on potato cultivation in Jilin Province over the past 58 years.
