The United States National Biosurveillance Strategy is the plan to implement a biosurveillance system that will monitor and interpret data that might relate to disease activity and threats to human or animal health – whether infectious, toxic, metabolic, and regardless of intentional or natural origin – in order to achieve early warning of health threats, early detection of health events ...
Diseases spread by ticks and other insects are becoming more common in the United States, but a new methodology for tracking Lyme disease may overestimate the significant spike in cases seen in 2022.
Active surveillance is a management option for localized prostate cancer that can be offered to appropriate patients who would also be candidates for aggressive local therapies (surgery and radiotherapy), with the intent to intervene if the disease progresses.
