Question

Dr. John Snow is best known for his work, which is coined “shoe leather epidemiology.” Provide a short summary of a modern-day epidemiologic surveillance activity.  

1. How is it similar and/or different from John Snow’s work?
2. Why is this important for public health?   

1. What information is gathered through this surveillance program? What kind of data, and who is collecting it?

Answer 1

Modern day epidemiological surveillance activity.

It includes the collection of epidemiological data that is required and first step is

1. Case detection-. Yes the case should be detected ,and this is the primary step . Detecting case can occur in a health care setting .
2. Then reporting of this out break is important as a step in epidemiology
3. These a well established team will investigate and confirm the condition and surveillance will be done
4. Analysis and interpretation of the epidemiologic outbreak and then establishing the epidemiologic triads are important that is the host , agent and environment factor in outbreak

Difference between John snows work and modern day epidemiological surveillance.

In the modern day concept the surveillance is done in a way that the detection will lead to reporting to the highest authority for surveillance, and then a team will do the analysis

In John snows work it was like reaching each and every house checking for an outbreak. There was lack of an established system. Analysis as well as interpretation was difficult

IMPORTANT FIR PUBLIC HEALTH

It is important for public health because

• Provides safety
• Helps to find method to fight against disease
• Help to find epidemiology triad
• Breaking the leag of triangle will help to fight disease
• Statistics will give idea and severity-of ddisease
• For setting health care center in hotspot region of disease

INFORMATION GATHERED FROM SURVEILLANCE PROGRAMS

The information gathered are

The agent which cause disease disease

Statistics

Host if disease

Environment of disess cause

Method for preventing

KIND OF DATA

Data is on the outbreak

Those who exhibit positive signs

Number of people infected

Number of recovery

Effectiveness of medicine

The data is collected by epidemiologist and specific department under it
