An endemic disease always has a steady, predictable number of people getting sick, but that number can be high (hyperendemic) or low (hypoendemic), and the disease can be severe or mild. [3] [4] Also, a disease that is usually endemic can become epidemic. [3] For example, chickenpox is endemic in the United Kingdom, but malaria is not.
Diseases are endemic when they occur regularly in certain areas according to established patterns, while a pandemic refers to a global outbreak that causes unpredictable waves of illness. The ...
Endemic is a frequently misunderstood and misused word outside the realm of epidemiology. Endemic does not mean mild, or that COVID-19 must become a less hazardous disease. The severity of endemic disease would be dependent on various factors, including the evolution of the virus, population immunity, and vaccine development and rollout. [2] [4 ...
Epidemiology has its limits at the point where an inference is made that the relationship between an agent and a disease is causal (general causation) and where the magnitude of excess risk attributed to the agent has been determined; that is, epidemiology addresses whether an agent can cause disease, not whether an agent did cause a specific ...
COVID-19 will never go away, but the pandemic will be over when the disease becomes 'endemic.' Here's what that means.
According to a more precise definition given by the Robert Koch Institute in Germany, hyperendemicity is not necessarily associated with a high incidence rate. A hyperendemic disease is one which is ubiquitously present with ongoing circulation in an endemic region with a high prevalence rate.
Omicron may make COVID an endemic disease. But "endemic" and "back to normal" are two very different things.
A medical dictionary definition of pandemic is "an epidemic occurring on a scale that crosses international boundaries, usually affecting people on a worldwide scale". [14] A disease or condition is not a pandemic merely because it is widespread or kills many people; it must also be infectious.
