What is Long COVID?

Long COVID (also known as post-acute COVID, chronic COVID, long-haul- COVID) is the name given to the symptoms people experience after two-weeks, which is how long COVID-19 symptoms are expected to last1.

A positive COVID-19 test should not be seen as a pre-requisite for Long COVID as many people were not able or did not meet the criteria to get tested in the early stages of the pandemic, and false negatives are not uncommon2. Some researchers are suggesting that long COVID is a spectrum3 or can be split into different phases defined by the amount of time symptoms are persisting for since initial COVID-19 diagnosis4,5.

What is the prevalence?

Globally, around one in five people who have tested positive for COVID-19 report a range of health symptoms more than five weeks after their first symptom6,7, and one in ten after more than 12 weeks7-9.

What are the symptoms?

Symptoms are highly variable. They can differ from the typical COVID-19 symptoms. For example, patients have reported fatigue, headaches, cough, anosmia, sore throat, chest pain and delirium, but they have also reported gastro-intestinal disturbances, skin rashes, metabolic disruption, muscle pain, fatigue, muscle weakness, and hair loss2,10-14.

Many organ systems may be involved and symptoms vary from mild (e.g. loss of smell) to severe (e.g. stroke, psychosis)14. Two papers have presented summaries of Long COVID symptoms, one in list form (can be accessed here)15 and one in a diagram (can be accessed here)16.

There is no specific time course: symptoms can improve one week only for relapse to occur the following week, and this pattern can last for more than one year after initial diagnosis6,7,17-20.

Who is at risk?

To date (14 June 2021), multiple studies shown that having a severe acute COVID-19 infection21, having comorbidities21, being an older adult22, and female9,22,23 is associated with an increased risk of Long COVID16,24.  However, many reports of Long COVID are from patients who had a mild case of COVID-19 and were not hospitalised6,17,25, and in younger adults9,21.

How to support patients with Long COVID?

As awareness of Long COVID increases among the public, patients are less concerned about the lack of care and empathy from others26,27, and more concerned about the intensity, duration and unpredictability of their symptoms13,28,29. Health professionals are in a difficult position to support their patients because of the lack of information on clinical definitions or treatments. Therefore, it is vital listen to patients’ about their concerns and validate their experiences30.

Health professionals should recommend medical or self-management based on symptoms and comorbidities2, and, if required, refer patients to specialist services for multidisciplinary assessment and rehabilitation31. It is recommended that primary care professionals also promote peer support and the use of reliable information sources, where appropriate2.

NZ HealthPathways local guidelines for the management of Long COVID are now live. Click here to visit the page.

There are emerging anecdotal reports about Long COVID symptoms improving within a few days after patients receive their second vaccine shot32-34. However, only one non-peer-reviewed prospective study has been conducted so far35, and one article suggests that the effects of the vaccine on Long COVID may be temporary or placebic in nature36.  

New research findings about Long COVID and how to best manage or treat it are being published frequently. This page will be updated as new peer-reviewed evidence and guidance becomes available.
