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.

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 symptom3,4, and one in ten after more than 12 weeks4.

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 loss,2,5-9.

Many organ systems may be involved and symptoms vary from mild (e.g. loss of smell) to severe (e.g. stroke, psychosis)10.

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 three months3,4,11,12.

Who is at risk?

To date (1 April 2021), no conclusions can be made about the risk of developing Long COVID based on age, sex, ethnicity, or underlying health conditions. Studies that have followed patients who were hospitalized with acute COVID-19 disease in Italy13-15, the Netherlands16, the U.K.17,18, the USA19, the Mediterranean20, and China6,21 have demonstrated differences in symptoms depending on the severity of their infection. However, many reports of Long COVID are from patients who had a mild case of COVID-19 and were not hospitalised3,11,22.

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 others17,23, and more concerned about the intensity, duration and unpredictability of their symptoms9,24,25. 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 experiences26.

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 rehabilitation27. 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.

There are emerging anecdotal reports about Long COVID symptoms improving within a few days after patients receive their second vaccine shot27-29. However, only one non-peer-reviewed prospective study has been conducted so far30.

NZ HealthPathways are currently developing local guidelines for the management of Long COVID.

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.
