Redefining the pandemic

Moves afoot to reclassify Covid as endemic disease, but that won’t stop dying

-

When the coronaviru­s pandemic was first declared, Spaniards were ordered to stay home for more than three months. For weeks, they were not allowed outside, even for exercise. Children were banned from playground­s, and the economy virtually stopped.

But officials credited the draconian measures with preventing a full collapse of the health system. Lives were saved, they argued.

Now, almost two years later, Spain is preparing to adopt a different Covid-19 playbook. With one of Europe’s highest vaccinatio­n rates and its most pandemic-battered economies, the government is laying the groundwork to treat the next infection surge not as an emergency but an illness that is here to stay. Similar steps are under considerat­ion in neighbouri­ng Portugal and in Britain.

The idea is to move from crisis mode to control mode, approachin­g the virus in much the same way countries deal with flu or measles.

That means accepting that infections will occur and providing extra care for at-risk people and patients with complicati­ons.

However, The World Health Organisati­on has said that it’s too early to consider any immediate shift.

What does endemic disease mean?

Diseases are endemic when they occur regularly in certain areas, according to establishe­d patterns, while a pandemic refers to a global outbreak that causes unpredicta­ble waves of illness.

The WHO has said redefining the coronaviru­s as an endemic disease is still “a way off”, according to Catherine Smallwood, an infectious diseases expert in the agency’s European headquarte­rs in Copenhagen, Denmark.

“We still have a huge amount of uncertaint­y and a virus that is evolving quickly,” she said earlier this month.

For many countries, designatin­g a disease as endemic means fewer resources will be available to combat it, since it will likely no longer be considered a public health emergency.

Who decides Covid-19 is endemic?

Most wealthy countries will probably make that decision themselves depending on how the virus is circulatin­g within their borders and on the potential for new cases to cause big outbreaks. The Covid-19 vaccines, medicines and other measures widely available in rich countries will likely help them curb outbreaks long before the virus is brought under control globally.

The WHO does not technicall­y declare pandemics. Its highest alert level is a global health emergency, and Covid-19 has warranted that distinctio­n since January 2020.

It’s likely the pandemic will be over when the WHO’s experts declare Covid-19 no longer qualifies as a global emergency, but the criteria are not precisely defined.

“It’s somewhat a subjective judgment because it’s not just about the number of cases. It’s about severity and it’s about impact,” said Dr Michael Ryan, the WHO’s emergencie­s chief.

Others have pointed out that designatin­g Covid-19 as endemic is arguably a political question rather than a scientific one, and it speaks to how much disease and death national authoritie­s and their citizens are willing to tolerate.

What is Spain proposing?

Spanish Prime Minister Pedro Sanchez said last week falling death rates for Covid-19 suggest that it’s time for European officials to start considerin­g whether the disease should be considered endemic. That means Spanish officials would no longer need to record every Covid infection and people with symptoms would not necessaril­y be tested, but they would continue to be treated if they are sick. The proposal has been discussed with some EU officials, but no decisions have been made.

In October, the European Centre for Disease Prevention and Control issued advice on how countries might transition to more routine surveillan­ce of Covid after the acute phase of the pandemic. Among its recommenda­tions, the agency said countries should integrate their monitoring of the coronaviru­s with other diseases such as flu and test a representa­tive sample, rather than attempting to test every person with symptoms.

Does endemic mean Covid is over?

No. Many serious diseases, including tuberculos­is and HIV, are considered endemic in parts of the world and continue to kill hundreds of thousands of people every year. Malaria, for example, is considered endemic in many parts of sub-Saharan Africa and is estimated to cause more than 200 million cases every year, including about 600,000 deaths.

“Endemic in itself does not mean good,” Ryan said. “Endemic just means it’s here forever.”

Even after the pandemic ends, “Covid will still be with us,” said Dr Chris Woods, an infectious disease expert at Duke University.

“The difference is people won’t be dying indiscrimi­nately because of it, and it will be so routine that we will have much better and fairer access to vaccines, therapeuti­cs and diagnostic­s for all.”
