An epidemic (from the Greek above the people) is the rapid spread of a known or unknown infectious disease that strikes a large number of people in the same place. Like laws, definitions have room for interpretation. The term “rapid” is open to discussion: a few days, weeks or months. The same place can be a school, a valley, a barracks or a city. The term “pandemic” is used when referring to the entire world, while the terms “episcolia” or “epipolis” do not exist. But it is certainly “large number” that is subject to the greatest variety of interpretations. Mathematical reason requires us to speak in percentages: five schoolchildren in a school of 1000 students is more important than two million people in the world. The all-time record is obviously that of the plague which decimated 30% of the population of an entire continent. An unsurpassable record, let’s hope, which has demonized the word epidemic in the collective unconscious of all subsequent generations. Personally, it is nice for me to know that I am a descendant of those who survived long enough to have had time to reproduce. This reassures me somewhat about the quality of my immune system.
Infectiologists and epidemiologists, who are more reasonable by nature, are more likely to use the term “emergence“, which is defined as an infection that has recently appeared in a population or that has already existed but whose incidence or geographical distribution is increasing rapidly. A more modest definition with its terms “incidence” and “distribution”. As for the adverb “rapidly”, it rather implies months or years.
Between 1940 and 2004, there were 335 outbreaks worldwide and more than a hundred in the 21st century. As for truly new human infections, the average is five per year. I don’t know why the general public is only aware of a tiny fraction of these outbreaks, while others occupy the headlines for months. This sociological question is too complex for me. The only factor I managed to note concerns the WHO announcements. It seems that when this international institution decides to warn of an outbreak, all countries without exception put their ministries in line regardless of the location of the outbreak. This proves at the very least that our leaders and their appointed experts, no longer having any opinion or decision-making autonomy, submit to the media and to the vagaries of the precautions of a few influential WHO leaders.
Without being able to presume the future of this second emergence of mpox virus, we can at least affirm that it is part of a very long list familiar to epidemiologists. And when I heard a radio talk about an epidemic in Europe because there had been a case, I realized that the semantic catastrophe threatened us more than the infectious catastrophe.

Understanding Epidemics: Definition, Interpretation, and Emergence
An epidemic, a term derived from the Greek “epi demos,” meaning “above the people,” refers to the rapid spread of a known or unknown infectious disease that affects a large number of people in a specific geographic area. While the concept may seem straightforward, the nuances of an epidemic’s definition have led to varying interpretations among experts and the general public.
Defining an Epidemic: Rapid Spread and Geographic Scope
The rapid spread of an infectious disease is a critical component of an epidemic. However, the term “rapid” is open to interpretation, with some experts considering it to be a matter of days, weeks, or even months. Additionally, the geographic scope of an epidemic can range from a small area, such as a school or a valley, to a larger region, such as a city or a country.
Interpreting the Term “Large Number”
The definition of an epidemic also relies on the phrase ”large number” of people affected, which can be subject to varying interpretations. From a mathematical perspective, it’s essential to consider the percentage of the population affected, rather than the absolute number. For instance, five cases in a school of 1000 students may be more significant than two million cases globally.
Pandemics and Emergences: Distinctions and Similarities
While an epidemic refers to a localized outbreak, a pandemic describes a widespread outbreak that affects the entire world. In contrast, the terms “episcolia” or “epipolis” do not exist, highlighting the absence of specific terminology for smaller-scale outbreaks.
Infectiologists and epidemiologists often use the term “emergence” to describe an infection that has recently appeared in a population or has existing but is increasing rapidly in incidence or geographic distribution. This definition is more modest, with a focus on incidence and distribution rather than rapid spread.
Historical Context: Epidemics Throughout the Ages
The all-time record for an epidemic is the plague, which decimated 30% of the population of an entire continent. This devastating event has left an indelible mark on the collective unconscious, demonizing the term “epidemic” in the minds of subsequent generations.
The Frequency of Epidemics
Between 1940 and 2004, there were 335 reported outbreaks worldwide, with over a hundred occurring in the 21st century alone. Additionally, an average of five new human infections emerge each year. Surprisingly, only a small fraction of these outbreaks receive widespread attention, while others dominate headlines for months. This phenomenon raises questions about the sociological factors influencing public awareness and response.
The Role of the World Health Organization (WHO)
The WHO plays a crucial role in announcing and responding to outbreaks. When the WHO warns of an outbreak, all countries, regardless of their location, take action, demonstrating the significant impact of international warnings on national responses.
Conclusion
understanding epidemics requires a nuanced appreciation of their definition, interpretation, and emergence. By recognizing the complexities of these concepts, we can better prepare for and respond to infectious disease outbreaks, ultimately saving lives and mitigating the impact on global health.

Understanding Epidemics: Definition, Interpretation, and Emergence
An epidemic, a term derived from the Greek “epi demos,” meaning “above the people,” refers to the rapid spread of a known or unknown infectious disease that affects a large number of people in a specific geographic area. While the concept may seem straightforward, the nuances of an epidemic’s definition have led to varying interpretations among experts.
Defining an Epidemic: The Role of Time and Geography
The term “rapid” in the definition of an epidemic is open to discussion. Does it imply a few days, weeks, or months? Similarly, the phrase “same place” can refer to a school, valley, barracks, or city. The World Health Organization (WHO) uses the term “pandemic” when referring to the global spread of a disease, but the terms “episcolia” or “epipolis” do not exist.
The Importance of Scale: Interpreting “Large Number”
The interpretation of a “large number” of people affected is also subjective. Mathematical reasoning requires us to speak in percentages: five schoolchildren in a school of 1000 students is more significant than two million people worldwide. The all-time record is, of course, the plague, which decimated 30% of an entire continent’s population, a record that has demonized the word “epidemic” in the collective unconscious of subsequent generations.
Infectiologists’ Perspective: The Term “Emergence”
Infectiologists and epidemiologists, being more reasonable by nature, are more likely to use the term “emergence,” defined as an infection that has recently appeared in a population or has existed but is increasing rapidly in incidence or geographical distribution. This definition is more modest, with its terms “incidence” and “distribution,” implying months or years rather than days.
The Frequency of Epidemics: A Look at the Statistics
Between 1940 and 2004, there were 335 outbreaks worldwide, with over a hundred in the 21st century. As for truly new human infections, the average is five per year. It is intriguing that the general public is only aware of a tiny fraction of these outbreaks, while others occupy the headlines for months. This sociological question is too complex to be addressed here.
The Role of the World Health Organization (WHO)
One factor that contributes to the awareness of epidemics is the WHO’s announcements. When the WHO warns of an outbreak, all countries put their ministries on alert, regardless of the outbreak’s location. This suggests that our leaders and their experts submit to the media and the precautions of a few influential WHO leaders.
The Future of Epidemics: A Long List of Familiar Cases
As we face the emergence of new diseases, such as mpox virus, we can affirm that it is part of a long list familiar to epidemiologists. The semantic catastrophe of misinformation and sensationalism threatens us more than the infectious catastrophe itself.
understanding epidemics requires a nuanced understanding of the definition, interpretation, and emergence of infectious diseases. By recognizing the complexities of epidemics, we can better prepare for and respond to future outbreaks.
