Coronavirus Declared a Pandemic. What Does That Mean?

Director-General Tedros Adhanom Ghebreyesus of the World Health Organization (WHO), a specialized agency of the United Nations that is concerned with world public health, announced on March 11 in Geneva that "[t]here are now more than 118,000 cases in 114 countries, and 4,291 people have lost their lives."

In the days and weeks ahead, we expect to see the number of cases, the number of deaths, and the number of affected countries climb even higher.

WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming levels of spread and severity, and by the alarming levels of inaction.

We have therefore made the assessment that COVID-19 can be characterized as a pandemic. 

According to WHO, "a pandemic is declared when a new disease for which people do not have immunity spreads around the world beyond expectations," writes Melissa Davey for The Guardian.

Once a pandemic is declared, it becomes more likely that community spread will eventually happen, and governments and health systems need to ensure they are prepared for that.

An epidemic, on the other hand, is a sudden increase in cases of an illness or disease that can be unique to one country or community.

Davey clarifies Tedros' statement that "[w]e have never before seen a pandemic sparked by a coronavirus. This is the first pandemic caused by a coronavirus."

The Severe acute respiratory syndrome (SARS) -related coronavirus, "identified in 2003, was not declared a pandemic by the WHO despite affecting 26 countries. However, its spread was contained quickly, and only a handful of nations were significantly affected, including China, Hong Kong, Taiwan, Singapore and Canada."

Why not to call it a pandemic?

If declaring a pandemic triggers global panic, this can defeat the purpose of trying to raise awareness. Much has been written about whether the declaration of H1N1, colloquially known as “swine flu”, as a pandemic in 2009, caused unnecessary panic, overwhelming emergency departments and causing governments to overspend on antiviral medications. Coronavirus symptoms are generally mild and most people recover within six days.

Finally, by calling in a pandemic, nothing really changes in terms of how to approach the disease. WHO continues to urge countries to “detect, test, treat, isolate, trace and mobilise their people”.

“The use of this term, however, highlights the importance of countries throughout the world working cooperatively and openly with one another and coming together as a united front in our efforts to bring this situation under control," states Dr Nathalie MacDermott, a National Institute for Health Research academic clinical lecturer at King’s College London.
