The continuous spread of COVID-19, especially the emergence and spread of a series of mutant strains, has brought new challenges to the development of human society, and the emergence of sewage epidemiology has provided a new idea for the early warning and detection of COVID-19 in countries around the world. By analyzing the rationality and optimal site selection of sewage sampling sites in the United States, early warning of the local epidemic development trend was conducted, and corresponding measures were proposed for epidemic prevention and control by the local government. The BP neural network prediction method is adopted to carry out deep learning and prediction of the changes in the number of infected persons in the next 5 weeks in each state of the United States based on the data related to the number of infected persons in the recent 18 weeks in the United States with 70% training ratio, 15% verification ratio and 15% rationality ratio. In addition, the epidemic development trend of each state in the United States is visualized in the form of the top ten regions in the United States. The threshold of epidemic development in each state of the United States was calculated by using SIR epidemic model, and the prediction results of BP neural network model were used to obtain the areas likely to break out large-scale epidemic, and based on the results, prevention and control suggestions were put forward for the areas likely to break out large-scale epidemic.
