Wastewater Surveillance for Communicable Diseases

Abstract


 This Horizon Scan summarizes the available information regarding wastewater epidemiology, or wastewater surveillance, for the detection of pathogens that cause communicable diseases.
 Wastewater surveillance can detect the presence of pathogens or chemical substances within the wastewater system and allows for the monitoring of a broad population with a single sample.
 Wastewater surveillance has been used for decades but has become more common since it was implemented around the world for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19. In Canada, wastewater surveillance is currently used for the detection of SARS-CoV-2, influenza, and respiratory syncytial virus.
 Studies conducted in Canada and internationally indicate that wastewater surveillance can be used as a reliable method for detecting pathogens at the population level.
 Future uses of wastewater surveillance may include monitoring of antibiotic use and antibiotic resistance, detection of cancers in the population, or assessing the prevalence of other infections within communities.

Chatbots in Health Care: Connecting Patients to Information

“…CADTH produced a report on the use of AI in pre-hospital emergency health care in August 2023. 1 This report is not a systematic review and does not involve critical appraisal or include a detailed summary of study findings. It is not intended to provide recommendations for or against the use of the technology and focuses only on AI chatbots in health care settings, not broader used of AI within health care.…”
