Hi All!

The Idol of Hospital has been constructed in previous presentation.

Now we have to decorate it with inclusion of various hospital services there in, but, this is only possible when I receive comments on previous presentations, and so you have to wait till then.

Today we will be discussing on a new subject, ‘The Epidemiology’
Most of you who have a medical background, have read about epidemiology in your graduation courses. Epidemiology is at the core of Public health. It assists in identification of health related conditions and suggests how to control and prevent them to stay healthy.

What is the concept of epidemiology, how it helps in health administration and the factors responsible for causing ill health conditions are explained in this presentation.


  1. sir,How epidemiology of any disease(H1N1) helps us in controlling recent epidemic

  2. " Thanks shoot19 for your query.

    Epidemiology assists in finding out the frequency( severity), distribution (Area affected) and determinants (influencing factors) for any disease epidemic.

    It provides the causal factor(Agent) and Natural history of disease process. It spells out the 'dynamics of disease transmission i.e. What is the Agent, Who are the susceptible hosts, and mode of transmission of the disease in a suitable environment through surveillance.

    Once these informations are obtained through epidemiological investigations, control measures can be initiated not only to control the recent epidemics by preventing transmission, but also to treat the cases for the present and future prevention.

    Further details will be available in my ensuing presentation on "Investigation and Management of Epidemics".

  3. sir , can u tell me pointwise that what r the epidemilogical methods india adopted to control h1n1 epidemic & what was the impact of epidemic of h1n1 on our existing health system .

  4. Thanks Dr, Poonam,

    The epidemiological methods applied in any epidemic are similar.
    However since H1N1 was pandemic the following methods were applied:

    i) Quarantine of suspected cases
    ii) Contact tracing
    iii)Screening of suspects and close contacts.
    iv) both sentinel and special epidemic surveillance
    v) Laboratory diagnosis for confirmation.
    vi) Prophylactic and treatment with Tamiflu.
    vii)Health education through mass media.

    There was a massive impact on health system, as we were not prepared early to face such a big epidemic, as a result-
    There was shortage of drugs,
    testing labs, trained man power, and ICU beds.
    How ever we learn from experience and India now is prepared to face any such epidemic in future.
