Containing acute disease outbreak

Area of Science:

• Epidemiology
• Public Health
• Geographical Information Systems

Background:

• Epidemiological surveillance is crucial for disease prevention, outbreak identification, and evaluating control strategies.
• Acute infectious diseases pose significant public health challenges requiring effective containment measures.

Purpose of the Study:

• To develop a novel Geographical Information System (GIS) based Digital Ring Fence (DRiF) strategy for acute infectious disease containment.
• To enhance epidemiological surveillance and disease control efforts.

Main Methods:

• Utilizing a secure database to capture probable case data.
• Employing postal codes for precise mapping of cases on a multi-layered GIS.
• Constructing a Digital Ring Fence (DRiF) around case locations using Non-Homogeneous Poisson Process (NHPP) modeling to estimate infection risk.

Main Results:

• Simulation studies indicate the DRiF strategy's potential as a novel approach for containing acute disease outbreaks.
• The DRiF strategy effectively identifies population concentrations for targeted outbreak containment.

Conclusions:

• The Digital Ring Fence (DRiF) strategy provides a method to contain infectious disease spread by creating a defined zone.
• This approach is vital for tackling outbreaks like SARS and can be applied to avian flu containment and preventing human-to-human transmission.
