Enteric outbreak surveillance in British Columbia, 2009-2013.
Summary
This study analyzed 104 enteric disease outbreaks in British Columbia (BC) from 2009-2013, identifying norovirus, Salmonella, and E. coli as common pathogens. Findings inform public health planning and prevention strategies for foodborne illnesses.
Area of Science:
- Public Health and Epidemiology
- Infectious Disease Surveillance
Background:
- Understanding enteric disease outbreaks is crucial for effective public health planning, policy development, and prevention programs.
- Identifying outbreak sources, disease burden, transmission modes, and interventions is key to controlling infectious diseases.
Purpose of the Study:
- To describe trends in enteric disease outbreaks investigated in British Columbia (BC) between 2009 and 2013.
- To analyze pathogen types, sources, settings, and contributing factors of enteric disease outbreaks in BC.
Main Methods:
- Analysis of enteric disease outbreaks reported to the Canadian Network for Public Health Intelligence (CNPHI) in BC from 2009-2013.
- Data included pathogen, case numbers, hospitalizations, deaths, setting, transmission mode, source, contributing factors, and interventions.
- Exclusion of residential facility-based viral outbreaks and those linked to international travel.
Main Results:
- 104 outbreaks were investigated in BC between 2009 and 2013, averaging 21 per year.
- Commonly identified pathogens included norovirus, Salmonella, and E. coli; food service establishments were the most frequent setting.
- The study identified a Salmonella-egg pathogen-food source combination and reported 108 hospitalizations and two deaths.
Conclusions:
- This is the first publication summarizing enteric disease outbreak trends, sources, burden, and interventions in BC.
- Continued reporting and analysis of outbreak data are essential for assessing trends and understanding intervention effectiveness.

01:26Principles of Disease Surveillance
570
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...

01:18Steps in Outbreak Investigation
596
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:

01:25Immune Surveillance by NK Cells and Phagocytes
8.9K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

01:18Drug Delivery: Enteral Route
1.9K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

1.0K
The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...
