The ACES Pandemic Tracker uses data from KFL&A Public Health’s Acute Care Enhanced Surveillance (ACES) system to monitor daily admissions to hospitals in Ontario for key syndromes related to COVID-19. ACES is a real-time syndromic surveillance system that uses natural language processing to group free text reasons for admission into different syndromes. These syndromes are not clinical diagnoses. Specifically, the ACES Pandemic Tracker looks at admissions related to pneumonia, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), and sepsis. The data is available by Local Health Integration Network (LHIN).
