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. It’s important to note that a positive COVID-19 test should not be seen as a pre-requisite for Long COVID as many people were not able to get tested and there are false negatives2.

What is the prevalence?

Globally, around one in ten people who have tested positive for COVID-19 report a range of health symptoms more than three weeks after their first symptom3.

What are the symptoms?

Symptoms are highly varied and 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 and muscle weakness2and hair loss2,4 Many organ systems may be involved and symptoms vary from mild (e.g. loss of smell) to severe (e.g. stroke, psychosis)4.

There is no specific time course: symptoms can improve one week only for relapse to occur the following week, and this pattern can last from three weeks to more than three months3,5,6.

Who is at risk?

To date (11 January 2021), no conclusions are able to be made about risk of Long COVID based on age, sex, or ethnicity, or other underlying health issues. Studies that have followed patients who were hospitalized with COVID-19 have demonstrated differences in symptoms depending on the severity of their infection in Italy7,8, the Netherlands9, the U.K.10,11, the USA12, and China13. However, many reports of Long COVID are from patients who had a mild case of COVID-19 and were not hospitalised3,5,14.

How to support patients with Long COVID?

Reports from patients indicates high levels of frustration with symptoms and the lack of care and empathy from others10. Many patients with Long COVID have reported feeling dismissed by health professionals. Although health professionals can be in a difficult position to support their patients, due to the lack of information, clinical definitions or treatments, it is vital that health professionals still listen to their patients concerns and validate their experiences15. Unlike many places overseas where health systems are overwhelmed, and lockdowns are limiting access to health services here in New Zealand patients with Long COVID can present to clinicians for support and treatment. Health professionals should recommend medical or self-management based on symptoms and comorbidities2, and referrals to specialist services made as needed. It is recommended that primary care professionals also promote peer support and information platforms where appropriate2.

Research into Long COVID and how to best manage or treat it is being published frequently. This page will be updated as new peer-reviewed evidence and guidance becomes available.
