Definition of Pandemia

Pandemia term of health sciences, which has become popular today due to the situation that the world is going through in relation to CoVID-19. The WHO has declared a pandemia, and today at we will tell you the meaning of this.

We speak of a pandemia when there is a worldwide spread of a new disease. The origin of this word is linked to the Greek pan which means everyone and demos people.

The WHO has highlighted some qualities to call itself a pandemic.

  • The virus must be new, not previously registered and that there is no population immune to it.
  • That the virus is capable of producing significant complications that compromise the patient’s life.
  • And that it is capable of being transmitted from person to person.

It must be mentioned that for a new disease to become a pandemia it must first be declared an epidemic.

The epidemia would be the number of new cases reported in a localizable area.

When this disease is spread by other means to other cities in the world and cases begin to manifest, then it becomes a pandemia.

One of the factors that influences the manifestation of a pandemia are patients who are carriers or asymptomatic and migrations.

This is why when a new virus or pathogen is reported, the relevant authorities take exhaustive measures at these key points.
