A Chinese cohort study published earlier this month in The Lancet medical journal found that more than 75% of patients that were previously hospitalised with Covid-19 had at least one lingering symptom six months later.

These symptoms range from muscle weakness and fatigue, anxiety and depression, to more severe respiratory issues.

“[Covid-19] has three phases. It is either asymptomatic or you just have some upper respiratory tract symptoms, then it could progress into the pneumonic phase, but that pneumonic phase is associated with inflammation systemically, and that inflammation can have long-term [consequences],” he explains.

This can be replaced by nicotinic acid , and a large number of people worldwide are already being treated on a product that contains nicotinic acid along with other agents like Zinc, [and] Vitamin C,” says Richards. But this is a hypothesis, he says, and there is currently no study saying definitively that this is the case.

Viral pneumonia occurs when small air sacs in the lung called alveoli, fill with fluid, he explains, whereas ARDS is much more severe and indicates a disruption of the barrier that separates air and blood in the lungs. Viral pneumonia will resolve both clinically and radiologically in about 12 weeks, says Calligaro, while Ards is a much longer game.“[Ards] carries a much higher mortality, and it’s associated with much more in the way of lung damage and fibrotic change.

We’re not 100% sure how many people are going to suffer from ongoing symptoms. It’s not the case in all circumstances, but conversely it actually is the case that some patients in the acute illness are relatively asymptomaticAs this occurs, our bodies also produce what are called neutralising antibodies, which protect our cells from becoming infected with virus.

“We’ve [also] started a post-Covid clinic, which we’re hoping will be multidisciplinary and have input from psychologists [and] chronic pain [specialists].”
