      • The amount of a particular disease that is usually present in a community is referred to as the baseline or endemic level of the disease. This level is not necessarily the desired level, which may in fact be zero, but rather is the observed level.

  1. Endemic refers to the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area. Hyperendemic refers to persistent, high levels of disease occurrence. Occasionally, the amount of disease in a community rises above the expected level.

    The Centers for Disease Control and Prevention (CDC)(link is external and opens in a new window)describes an epidemic as an unexpected increase in the number of disease cases in a specific geographical area. Yellow fever, smallpox, measles, and polio are prime examples of epidemics. An epidemic disease doesn't necessarily have to be contagious. Wes...

    The World Health Organization (WHO)(link is external and opens in a new window)declares a pandemic when a disease’s growth is exponential. This means the growth rate skyrockets, and each day cases grow more than the day prior. In being declared a pandemic, the virus has nothing to do with virology, population immunity, or disease severity. It means...

    A disease outbreak is endemic when it is consistently present but limited to a particular region. This makes the disease spread and rates predictable. Malaria, for example, is considered endemic in certain countries and regions.

    The WHO defines pandemics, epidemics, and endemic diseases based on a disease's rate of spread. Thus, the difference between an epidemic and a pandemic isn't in the severity of the disease, but the degree to which it has spread. A pandemic cuts across international boundaries, as opposed to regional epidemics. This wide geographical reach is what m...

    Several factors contribute to the outbreak of infectious diseases. Contraction can occur as a result of transmission from people, animals, or even the environment. For example: 1. Weather conditions.(link is external and opens in a new window)For example, whooping cough occurs in spring, whereas measles tends to appear in the winter season. 2. Expo...

    The current COVID-19 outbreak is not the only disease to have impacted the world on a global scale. Here are just a few examples of past pandemics that have shaped the evolution of outbreaks and human immunity: The Black Death (1346 - 1353):(link is external and opens in a new window)The Black Death caused an estimated death of 25 million people ac...

    A common attribute of epidemics and pandemics is the need to take preventive care of infection. Typically, there is a large time lag between an outbreak and when vaccinations can be distributed, as we have seen with COVID-19. In the meantime, it’s crucial to take the following steps to stay healthy: 1. Wash your hands often with soap and water. Mak...

  4. Jul 15, 2024 · By definition, a disease is said to be endemic if the prevalence remains stable within a region and persists with fairly predictable rates of infection and spread. Endemic diseases do not have to be present at high levels.

  5. Jul 14, 2017 · Health insurance organizations, which at this stage are able to predict risk, may start to cover any response in their insurance benefits (and premiums). The disease itself takes on an “identity,” and interest groups form out of the populations where the disease is becoming endemic, often advocating for attention and action.

  6. Jan 13, 2022 · Colds and flu, for instance, are endemic, circulating every winter. But given the high levels of transmissibility of SARS-CoV-2, the virus that causes COVID-19, some experts consider COVID to be endemic already.

  7. Mar 16, 2022 · The Centers for Disease Control and Prevention (CDC) says an endemic is “the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area.”...
