Advancements in technology have significantly improved signal detection capabilities:
1. Big Data: The integration of large datasets from various sources, including social media, electronic health records, and mobile health apps, provides a more comprehensive view of potential signals. 2. Machine Learning: Algorithms can learn from historical data to identify patterns that may indicate emerging threats. 3. Real-Time Surveillance: Systems like ProMED-mail and HealthMap provide real-time monitoring and reporting of potential outbreaks.
