UN health agency issues definition of post COVID-19 condition to aid treatment

The first official clinical definition of “post COVID” condition has been agreed upon after global consultation and released to help boost treatment for sufferers, the UN World Health Organization (WHO) said on Friday.

The emerging illness, which is also referred to as “long COVID” among many other similar iterations, occurs in individuals who have had confirmed or probable new coronavirus infections, “usually three months on from the onset of the COVID-19 (and) with symptoms that last for at least two months and cannot be explained by an alternative diagnosis” said Dr Janet Diaz, Head, Clinical Management, WHO.

Until now, a lack of clarity among health care professionals about the condition has complicated efforts in advancing research and treatment, WHO explained, in a document detailing its reasons for pursuing a globally standardized clinical case definition.  

Speaking via Zoom at UN Geneva, the WHO official explained that symptoms include “fatigue, shortness of breath, cognitive disfunction, but also others which generally have an impact on everyday functioning. Symptoms may be new-onset, following the initial recovery from the acute episode, or persist from the initial illness. And then symptoms can also fluctuate or relapse over time.”

In issuing the definition, WHO noted that most patients who suffer from COVID-19 fully recover, although some suffer “long-term effects on several body systems, including pulmonary, cardiovascular and nervous systems, as well as psychological effects”. These effects can happen irrespective of the initial severity of infection; they also occur more frequently in women, middle age, and in those who displayed more symptoms initially.

Describing the new definition as “an important step forward” in standardizing the recognition of patients with post COVID-19 condition, Dr Diaz said it was the UN agency’s hope that “it will help clinicians and health workers recognize patients and start them on appropriate treatments and interventions and clear pathways. We hope that policymakers and health systems will set up and implement integrated health models to care for these patients.”

Although several tests exist for the initial COVID-19 infection, there is no such solution for post COVID-19 condition, and it is still unclear exactly what triggers it in sufferers.

“Is it viral persistence, and/or, is there microthrombosis (or) some problem with the vasculature,” Dr Diaz said, outlining some of the current thinking among scientists carrying out research in the field. “And/or is there problems of autoimmunity, or the immune system that is disfunctioning and that’s causing some of the symptoms?”

The full definition of Post COVID-19 condition is the following:

“Post COVID-19 condition occurs in individuals with a history of probable or confirmed SARS-CoV-2 infection, usually three months from the onset of COVID-19 with symptoms that last for at least two months and cannot be explained by an alternative diagnosis. Common symptoms include fatigue, shortness of breath, cognitive dysfunction but also others which generally have an impact on everyday functioning. Symptoms may be new onset, following initial recovery from an acute COVID-19 episode, or persist from the initial illness. Symptoms may also fluctuate or relapse over time. A separate definition may be applicable for children.”
