Principles of Disease Surveillance01:26

Principles of Disease Surveillance

779
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...

Introduction to Global Positioning System

708
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Pharmacovigilance01:19

Pharmacovigilance

1.9K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

694
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:

Signal and System01:26

Signal and System

1.8K
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional...

Types of Global Positioning System Surveys01:30

Types of Global Positioning System Surveys

427
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

    Area of Science:

    • Epidemiology
    • Public Health
    • Infectious Disease Control

    Background:

    • The definition of public health surveillance has evolved significantly over 70 years.
    • Early surveillance focused on direct observation of individuals with specific contagious diseases.
    • Alexander Langmuir redefined surveillance as a critical, epidemiology-based factor in disease control.

    Observation:

    • Langmuir's redefinition emphasized systematic infectious disease reporting.
    • It included data analysis, epidemiologic interpretation, and prompt dissemination of findings.
    • The Communicable Disease Center (CDC) developed early surveillance systems for diseases like malaria, polio, and influenza.

    Findings:

    • Systematic reporting and rapid action based on surveillance data were crucial for the global smallpox eradication program.
    • Effective surveillance relies on comprehensive data collection, analysis, and timely communication.
    • The principles established by Langmuir remain foundational to modern public health surveillance.

    Implications:

    • Modern public health surveillance systems are more sophisticated due to technological advancements.
    • Understanding the historical development of surveillance provides context for current practices.
    • The success of disease control and eradication efforts is directly linked to robust surveillance infrastructure.
