What does COVID-19 Declaration mean a pandemic or a global pandemic?
On Wednesday, corresponding to 11/3-2020 AD, the World Health Organization (WHO) announced that the viral disease, “COVID-19”, which has swept at least 114 countries and killed more than 4000 people, is now a global epidemic or what is known as a pandemic. That the World Health Organization announced the last global epidemic before the new corona in 2009, when the H1N1 swine flu virus spread, as the World Health Organization said that in the past two weeks, the number of COVID-19 cases outside of China increased 13-fold and the number of affected countries increased to three times the previous number, as you expect to see in the coming days and weeks, a more rise in number Cases, and the number of deaths, and the number of countries affected by the virus, and accordingly the organization has conducted an assessment to be described COVID-19 global pandemic.
Classification of disease cases
Epidemiology is called the science for disease characterization, distribution, and control. In the United States of America, the Centers for Disease Control and Prevention (CDC) is the primary body that collects and supervises this data, in addition to many Among other tasks such as disease prevention guidelines and guidelines, it is worth noting that determining the level of disease occurrence is carried out by two measurable factors:
- The pattern and speed of disease of the disease known as the reproductive rate.
- The size of the population exposed to the disease known as Critical Community Size.
The difference between a pandemic and a pandemic (global epidemic)
Depending on the above, an epidemiologist may describe the condition of the disease in the following ways:
- Individual cases: or what is known as intermittent, where it refers to a disease that occurs irregularly, such as foodborne pathogens, such as salmonella or E. coli that can cause disease outbreaks intermittently.
- Cluster: This term refers to diseases whose causes or incidence rates are uncertain or unknown and usually occur in larger numbers of intermittent diseases. Examples include Increased cancer cases that are discovered after the disasters of nuclear or chemical plants.
- Endemic: Refers to the persistent presence and/or usual spread of disease usually in the population of a particular geographical area.
- Epidemic: It is usually triggered when there is a rapid increase in the number of disease cases above what is expected in a population of a particular region.
- Outbreak: This term has the same definition as an epidemic, but it is often used in a more limited geographical area.
- Pandemic: This term refers to a global epidemic that has spread across several countries or continents, and affects a large number of people, as is the case with the emerging coronavirus.
Usually, the prevalence of a specific disease such as the emerging coronavirus is detected by revealing a specific set of cases of the disease, and if it does not contain it at this stage, it may develop into an outbreak stage, and thus an increase in the number of cases in a specific geographical area, then it can It becomes a pandemic, or within a country or a local area, then if there is a wider spread of cases of the disease in many countries or continents or around the world, it becomes a global pandemic or what is known as a pandemic.
