An Overview of Emergencies, Outbreaks, and Pandemics

Epidemics and pandemics have devastated societies for centuries, and each has its own unique characteristics. They differ in their severity, the length of illness, and the ways in which they spread within a community. An outbreak of a new disease, with high rates of illness, can cause havoc for local health care providers and communities. In addition, it can decrease society’s ability to provide critical services.

The epidemic affects a huge population

Several different types of pandemics and outbreaks have occurred in the last century, with some more severe than others. The term “epidemic” refers to an unexpected increase in a disease in a given community. An outbreak is a single geographic area where many cases develop; a pandemic is an epidemic that spreads to several countries or continents and affects a large population.

The need to understand the different types of outbreaks and epidemics is crucial

As such, the need to understand the different kinds of outbreaks and pandemics is crucial for organizations that plan for such emergencies. For instance, a novel coronavirus (CCV) disease outbreak is likely to lead to a large scale epidemic that may spread throughout the world. The same applies to pandemics that occur in an isolated region. In the case of a global outbreak, the disease may spread across many countries.


The World Health Organization defines a pandemic as a disease epidemic in a region. An outbreak is an epidemic that has more than one case per 100 people. A pandemic, on the other hand, is a global epidemic of a disease. The term is typically used in the context of the flu, but it can occur in other types of diseases. This course provides an overview of the science behind pandemics and outbreaks, including WHO resources.
