Many long-haul COVID-19 patients have chronic fatigue syndrome and other breathing issues months after their initial diagnosis, according to a study.

Chronic fatigue syndrome is a medical condition that can often occur after a viral infection and cause fever, aching, and prolonged tiredness and depression.

The study, published in the journal JACC: Heart Failure, is the first of its kind to identify a correlation between long-haul COVID-19 and chronic fatigue syndrome.

The researchers noted that many COVID-19 patients, some who were never hospitalised, have reported persistent symptoms after they recover from their initial COVID-19 diagnosis.

These patients have Post-Acute Sequelae of SARS-CoV-2 infection (PASC) but are more commonly referred to as "long-haulers," the researchers said.

Severe fatigue, cognitive difficulty, unrefreshing sleep and muscle aches and pains have all been considered major symptoms for PASC patients, which is similar to what researchers saw after the 2005 SARS-CoV-1 epidemic, they said.

In that epidemic 27 per cent of patients fulfilled criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) after four years. In the latest study, researchers looked at 41 patients -- 23 women and 18 men -- with an age range of 23 to 69 years.

Patients were referred to the prospective study from pulmonologists or cardiologists and all had normal pulmonary function tests, chest X-rays, chest CT scans and echocardiograms.
