This is a new disease, so doctors are guessing when it comes to the symptoms people will have long term.

But it’s clear this virus has a sting in its tail. The sickest patients have damage to their lungs and kidney which could be permanent. Some research shows the risk of heart attack or stroke is high. File on 4 talks to people living with the after effects of Covid 19 who say surviving was just the beginning. There are a multiotide of physical after effects - and many more have suffered post-traumatic stress disorder. People describe flashbacks to the ITU, seeing people die, overhearing their last goodbyes with loved ones on phone or the internet.

Patients who were hospitalised get follow-ups, and referrals for rehabilitation and possibly, counselling.

But what of the hundreds of thousands of other people who fell ill and who, if it weren’t a pandemic, might have gone to hospital, but were told to stay at home?

Researchers say there are at least 300,000 people who have had symptoms of Coronavirus for more than a month – so called Long Haul Covid.

Many are young and previously fit. They say they had a mild case of the virus. But they have been floored by the symptoms that followed – breathlessness, racing heart, weakness. And they're struggling to get care and support.
