The 31-year-old nursing home worker is the first British man to catch and hit Covid-19 twice and is now facing another test
- The unnamed nurse from Reading has been tested for Covid-19 five times
- The mother of two children tested symptomatically and negative for the first time at the end of March
- In April, her condition worsened and she was retested and found positive
- She has since tested positive a second time after returning a negative test
A 31-year-old UK caregiver is one of only five people in the world who have tested positive for Covid-19 twice.
The woman, who has not been identified, has been tested for Covid-19 five times in the past five months.
She tested positive for the disease on two occasions.

The Reading, Berkshire mother-of-two told The Sun, "I always thought if you developed coronavirus you would be immune afterward, but maybe I'm a special case."
“When I first caught it, it was almost to be expected given the nature of my job. But I never expected to get it twice. & # 39;
She said she first became symptomatic in March, with shortness of breath, high temperatures and high blood pressure. She had her first Covid-19 test in early April and it has been confirmed that she has the disease.
She was retested two weeks later and came back negative.
She became symptomatic in June and was rushed to the hospital where she was tested, which gave a negative result.
Since she works in a nursing home, the mother was asked to stay at home until her condition improved, despite the second negative test.
What is the Truth About Immunity To COVID-19?
Scientists still don't know for sure if people can catch Covid-19 more than once or if they become immune after their first infection.
With some diseases, such as chickenpox, the body can remember exactly how to destroy them and fight them off before symptoms start when they get back into the body.
However, it is so far unclear whether people who have had coronavirus can get it again.
Tests have shown that many people who recover have antibodies – which can provoke future immunity – but it's not known if there are enough of them.
However, antibodies are just one type of substance that can induce immunity. The immune system is a huge network of proteins that have various functions to protect the body from infection.
Others, including white blood cells called T and B cells, can also help the body fight disease, but are more difficult to detect with the tests currently available.
There are initial indications that antibodies disappear as early as eight weeks after being infected with the coronavirus, scientifically called SARS-Cov-2.
On the other hand, T cells that target and destroy cells already infected with the virus are "permanent," said Professor Altmann.
A promising study in monkeys found that they failed to catch Covid-19 a second time after recovering from it, leading scientists to believe that the same could apply to humans.
The rhesus monkeys were purposely reinfected by scientists in China to test how their bodies reacted.
With the coronavirus only known to scientists for seven months, there wasn't enough time to investigate whether people develop long-term immunity.
So far, cases where people have been infected more than once have been neither numerous nor convincing.
Two weeks ago she tested positive for Covid for the second time.
She told The Sun, "I was really not doing well when I contracted this disease in April. I stayed in bed for over a week. After successfully isolating and recovering myself, I went and was tested again.
“As I expected, I was negative and thought that was the end. I had never heard of anyone who got it twice. I was planning to go back to work and before I did I did another test. I didn't have any symptoms. I had the occasional headache one evening but that is the only thing I could think of was something else. & # 39;
She said she had no shortness of breath or a fever.
She took a fifth test at home on Monday and is now expecting a negative test again.
She said she was self-isolating but couldn't believe she contracted the disease a second time.
She hopes that the last test will be negative again because she has not been able to look after her children properly since April.
For the past six months, she has been corresponding with her family through Zoom most of the time.
A 33-year-old man in Hong Kong was the first to contract Covid-19 after developing two different strains.
Genetic analysis revealed that his second infection, which he caught while traveling to Europe, was caused by another strain of the virus.
All viruses – including SARS-CoV-2, the virus behind the pandemic – mutate over time. Analyzing the DNA of pathogens can identify changes that can make them weaker or more deadly.
Doctors warned of their findings that "re-infection can occur just months after recovery". They said it was likely that immunity would be short-lived and that antibodies to Covid-19 would fade quickly.
But the unidentified man had no symptoms of Covid-19 for the second time – he was only discovered through screening at an airport. This could suggest that he had some level of immunity that protected him from serious illnesses, experts say.
Covid-19 survivors can be re-infected twice, according to doctors in Hong Kong reporting the first known case
Hopes of permanent immunity have been hampered in the past few months by several reports claiming people have been hit by the coronavirus twice.
So far, however, scientists have repeated that cases of re-infection are more likely to be due to a test failure or that inactive particles of the virus are still present in patients' bodies months after the onset of the disease.
