Monitoring enterovirus concentration in wastewater compared with clinically confirmed case and its seasonal pattern

Abstract

Enterovirus can be found in surface water and wastewater from treatment plants. It causes the disease in children under the age of five-year-old. Enterovirus infection will cause hand, foot, and mouth disease, Gastrointestinal disease, and neurodegenerative diseases. It’s transmitted through the ingestion of contaminated food or water. Enterovirus outbreak usually occurs during the rainy season and the amount of enterovirus is more common during the summer. However, Thailand still has little information about the enterovirus outbreak. Therefore, it is important to further study the trends of enterovirus in Thailand. In this study, wastewater samples were collected from three treatment plants; Dindaeng, Chong nonsi and Nongkhaem. Samples were collected between December 2019 and May 2020 by sampling twice per month from the results show that the correlation between enterovirus concentration in each wastewater treatment plant is not significant (p > 0.05). In addition, clinical data of people infected with enterovirus case were analyzed with enterovirus concentration. The results show that there is no significance (p > 0.05). Also, the data of enterovirus prevalence and month was correlated to study the seasonal trend and the result shows that enterovirus did not have the specific trend in Thailand and there was not significant between temperature and humidity (p > 0.05).
