A British care worker and mum-of-two is one of only five people in the world to have tested positive for coronavirus twice.
Heidi Kray, 31, from Reading, Berkshire, has been tested for Covid-19 five times over the past five months – testing positive on two separate occasions.
She told The Sun: ‘I always thought that if you develop coronavirus once then you are immune after that, but maybe I’m a special case.
‘When I caught it the first time, it was almost expected given the nature of my job. But I never expected to get it twice.’
Heidi first started showing symptoms in March, suffering with shortness of breath, a high temperature and raised blood pressure. In early April a Covid-19 test came back positive.
Two weeks later she was tested again and that came back negative.
But in June, she felt ill again and was sent to hospital for another test but the result came back negative.
Heidi was asked to stay at home in order to minimise the risk to the vulnerable residents at her care home, despite the negative result.
But a fortnight ago – taking another precautionary test before returning to work – she tested positive for coronavirus for the second time.
‘I really wasn’t well when I contracted this disease in April. It left me in bed for over a week,’ she told The Sun.
‘Once I had successfully self-isolated and recovered, I went and got tested again. As I expected, I was negative and I thought that would be the end of it. I hadn’t heard of anyone getting it twice.
‘I planned to go back to work and before I did, I took another test. I had no symptoms. I got the occasional headache of an evening but that is the only thing I could think of that was any different.’
Heidi has been self-isolating and said she could not believe she had become infected for a second time. A fifth test was carried out on Monday and she is hoping for a negative result.
The mother-of-two has been unable to care for her children properly since April and for the past six months has spent most of her time talking to family over Zoom.
She said: ‘I feel guilty I have had so much time off. But I understand I need to take time off. I need to self-isolate and do what the medical professionals have told us to do.
‘If I don’t, I’m putting the people I care for at risk and I can’t have that on my conscience.’
An IT worker, 33, from Hong Kong was the first confirmed case of coronavirus reinfection.
He was first diagnosed at the end of March after showing the key symptoms but recovered and tested negative when he was discharged from hospital.
But he tested positive again last month, after returning to Hong Kong from Spain, via the UK. This time he had no symptoms.
Genetic analysis revealed he had caught two ‘completely different’ strains of the virus.
The Department of Health has said it is aware of emerging international evidence that suggests people could be infected more than once.
A spokesman said: ‘We have been clear we are still learning about immunity to Covid-19 and there are a range of possible reasons someone could test positive twice.’
