New data shows shifting epidemic trends in U.S. states based on Rt estimates

On July 18, 2025, the CDC released its latest statistical modeling and forecasting report on current epidemic trends across U.S. states, focusing on the Rt (reproduction number) estimates. This metric is crucial for understanding how infectious diseases are spreading or receding in different regions. The report highlights which states are experiencing increases or decreases in transmission rates, providing a valuable tool for public health decision-makers. By examining Rt estimates, the CDC aims to offer insights into the effectiveness of interventions and guide future policy decisions. The modeling and forecasting results emphasize the importance of continued vigilance and targeted health measures to control outbreaks. This comprehensive analysis not only aids in monitoring current epidemic dynamics but also helps in anticipating future health scenarios. For those interested in the latest public health data, the CDC’s update offers an in-depth look at how Rt estimates impact state-level epidemic trends.
