AI to predict COVID-19 hospitalizations from wastewater analysis

A new study demonstrates AI's potential for forecasting COVID-19 hospitalizations using wastewater sampling. Researchers from the University of Technology Sydney developed a model analyzing sewage data that accurately predicts hospitalizations up to 4 weeks out.

The team, including engineers Professor Qilin Wang and Dr. Xuan Li, evaluated wastewater across 159 US counties covering 100 million citizens. By comparing the data to real-world hospitalizations, their AI model achieved precise future projections. The innovative approach was published in Nature Communications.

As Dr. Li explained, wastewater contains information not captured by traditional testing like asymptomatic cases. The rich data source allowed the researchers to train an AI that identifies patterns and changes for accurate forecasting.

According to Professor Wang, most current wastewater monitoring only signals COVID-19 presence and general trends. Their AI modeling establishes a low-cost, scalable early warning system for health providers.

The model factors in policy impacts, vaccinations, holidays, weather and more influencing hospitalizations. It enables targeted pandemic response and optimal resource allocation up to a month in advance.

Dr. Li noted the technique could become a foundation for tracking COVID-19, other diseases, and evaluating outbreak impacts. The Australian Research Council and Australian Academy of Science supported the pioneering study.

Overall, the research highlights AI's immense potential with wastewater data to forecast COVID-19 hospitalizations. The approach may prove a life-saving and cost-effective tool for officials worldwide as it continues to evolve. The technology demonstrates AI's increasing role combating public health threats with alternative data sources.
