Insights

Medical teleconsultations using International Classification of Primary Care 2nd Edition (ICPC-2) codes can effectively monitor influenza trends. This method provides real-time data that aligns well with traditional surveillance systems.

Area of Science:

  • Public Health
  • Epidemiology
  • Digital Health

Background:

  • Traditional influenza surveillance relies on sentinel reporting systems.
  • Timeliness and completeness of data can be challenges in traditional surveillance.
  • Telemedicine offers a potential new data source for public health monitoring.

Purpose of the Study:

  • To investigate the utility of medical teleconsultation data for influenza surveillance.
  • To compare teleconsultation data with established influenza surveillance reports.

Main Methods:

  • Analysis of International Classification of Primary Care 2nd Edition (ICPC-2) codes from teleconsultations.
  • Focus on ICPC-2 codes related to influenza-like symptoms, particularly fever.
  • Comparison of teleconsultation data with weekly Swiss Sentinel influenza reports.

Main Results:

  • ICPC-2 codes successfully reproduced seasonal influenza peaks for 2007/08, 2008/09, and 2009/10.
  • Teleconsultation data revealed a higher early peak during the 2009 pandemic compared to Sentinel data.
  • This suggests potential underreporting in the traditional Sentinel system during the 2009 pandemic.

Conclusions:

  • Data from medical teleconsultations, utilizing ICPC-2 codes, enables real-time influenza surveillance.
  • Teleconsultation data demonstrates strong correlation with the Swiss Sentinel surveillance system.
  • This approach enhances the timeliness and potentially the accuracy of influenza monitoring.

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
