The corona virus outbreak has been labelled an epidemic by the World Health Organization (WHO).
It is a term that the organization had refrained from using before now.
WHO chief Dr Tedros Adhanom Ghebreyesus said it was now using the term because of deep concern over “alarming levels of inaction” over the virus.
What is an epidemic?
An epidemic describes an infectious disease where we see significant and ongoing person-to-person spread in multiple countries around the world at the same time.
The last time a deadly disease occurred was in 2009 with swine flu, which experts think killed hundreds of thousands of people.
Pandemics are more likely if a virus is brand new, able to infect people easily and can spread from person-to-person in an efficient and sustained way.
Corona virus appears to tick all of those boxes.
With no vaccine or treatment that can prevent it yet, containing its spread is vital.
Why is the term being used now?
At the end of February, Dr Tedros said while corona virus “absolutely” had pandemic potential it was not there yet because “we are not witnessing uncontaminated global spread”.
What has changed is the number of countries dealing with cases. There have now been 118,000 in 114 countries.

Changing the language does not change anything about how the virus is behaving, but the WHO hopes it will change how countries tackle it.
Dr Tedros said: “Some countries are struggling with a lack of capacity. Some countries are struggling with a lack of resources. Some countries are struggling with a lack of resolve.”
He added that the WHO was asking all countries to:
- activate and scale-up emergency response mechanisms
- communicate with people about the risks and how they can protect themselves
- find, isolate, test and treat every Covid-19 case and trace every contact.
