Public Health Surveillance
Public Health Surveillance
Public Health Surveillance provides the methods, tools and human resources required to support data, information and knowledge needs for public health programming.
The work includes:
- gathering and analyzing qualitative and quantitative data to inform decisions, policies and strategies
- program evaluation and monitoring activities
- addressing process, tool and procedure issues related to quality data collection
- surveillance of public health issues
Informatics, evaluation and surveillance
Public Health Surveillance provides leadership in informatics, evaluation and surveillance.
Informatics supports the systematic assessment, development, implementation, evaluation and sustainment of processes, tools and procedures necessary for quality data collection.
Evaluation provides answers to questions about the effectiveness or impact of a program and uses that information to make informed decisions related to program support and improvement.
Surveillance focuses on the ongoing and systematic collection, analysis and interpretation of health data to understand population health determinants and recognize and assess outbreaks and disease trends.
Public Health Surveillance continues to develop, refine and practice an integrated and collaborative approach to population health to provide the foundation for evidence-informed decision making that, in turn, supports improved health outcomes for all Nova Scotians.
Surveillance guidelines
The Nova Scotia Surveillance Guidelines for Notifiable Diseases and Conditions provide detailed guidance to public health staff in Nova Scotia on the reporting of notifiable diseases and conditions for surveillance purposes.

Respiratory Watch
Respiratory virus surveillance is an ongoing activity in Nova Scotia where respiratory viruses like COVID-19, influenza and RSV are monitored. The objectives of this surveillance are to:
- monitor and describe trends in activity levels of respiratory pathogens in Nova Scotia
- routinely disseminate timely surveillance data to inform public health action
- monitor and describe the epidemiology of respiratory pathogens overall and for severe outcomes
- detect, monitor and characterize emerging respiratory pathogens that may present as influenza-like illness (ILI) or Severe Acute Respiratory Infection (SARI) with the potential to cause outbreaks and epidemics
These objectives are met through analysis of data from multiple sources which are described in the Respiratory Surveillance Plan for Public Health (PDF).
The Respiratory Watch dashboard can be found at the Nova Scotia Respiratory Watch 2025-26. Historical reports are also accessible at the Respiratory Watch Report page.
School-Based Immunization Coverage in Nova Scotia
This report provides a summary of immunization coverage rates for the school-based immunization program in Nova Scotia.
Adverse Events Following Immunization (AEFI) Surveillance
This annual report provides a summary of adverse events reported following the administration of publicly funded vaccines in Nova Scotia, while also examining trends over time.
Oral Health in Nova Scotia Surveillance Report
This report describes the oral health of Nova Scotians, including the condition of their teeth, use of dental care services and factors influencing access to care. It provides a detailed overview of oral health measures such as dental conditions, care use and impacts on daily life. The report is based on data collected in 2024–2025 through the Canadian Health Measures Survey and supports public health monitoring and planning.

Lyme Disease Epidemiology and Surveillance in Nova Scotia
This report provides descriptive epidemiological information on Lyme disease cases reported in Nova Scotia from 2002-2011, describes Lyme disease endemic areas identified in the province and provides an overview of the outcomes of surveillance for blacklegged tick populations. This in-depth report is intended to summarize and document information on Lyme disease and tick surveillance to date in Nova Scotia. Surveillance information is routinely presented, with a more limited scope, in the annual notifiable disease surveillance report above.

HIV/AIDS in Nova Scotia Surveillance Report
This report describes trends in HIV/AIDS diagnoses reported to public health in Nova Scotia since the first person was diagnosed with AIDS in the province in 1983. The report examines cases newly diagnosed in Nova Scotia, focusing on cases reported in the last ten years (2002-2011). As well, enhanced surveillance information on HIV-1 subtypes, transmitted drug resistance mutations and HIV disease progression at diagnosis is also presented. This in-depth report is intended to summarize and document information on HIV/AIDS surveillance to date in Nova Scotia. Surveillance information is routinely presented, with a more limited scope, in the annual notifiable disease surveillance report above.
