The identity of a person from Seattle Is the third person to be infected twice with the novel coronavirus.
In March 60, a stranger contracted COVID-19 in March at a nursing home in Washington state and became so ill that he had to be hospitalized for 40 days.
Five months later, in July, he tested positive again after moving to a different facility, but this time his illness was mild and he recovered.
Genetic testing later revealed that the man was infected with two different strains.
The researchers say that because the patient was not very ill during his second round, it indicates that he developed some antibodies during the first round, even if it was not enough to prevent refraction.

A chart of all coronavirus species documented in the state of Washington is pictured. Genetic testing showed that the strain was similar to the one that first infected man in Wuhan (dark blue) and the second type (green) from Europe to the U.S. Came.
The man, who has a history of severe emphysema, tested positive for the virus on March 6, according to a pre-print published last month.
Researchers believe he may have been ill by a nursing home employee who recently returned from a trip to the Philippines with a respiratory infection.
He was hospitalized after experiencing severe symptoms such as fever, cold, cough, chest pain and shortness of breath. He also developed pneumonia.
A chest x-ray resulted in trapped air coming out of the lungs more than normal and he received supplemental oxygen and steroids.
The patient was hospitalized for about six weeks and was discharged after performing two negative tests on days 39 and 41.
In July, after visiting another nursing home, the patient reported to residents that he was suffering from a cough.
After coughing and difficulty breathing for two weeks, he was sent to the ER on July 29, where he tested positive for the second time.
Researchers say his second illness was much less serious and he recovered after being treated with rimadesivir and dexamethasone.
Genetic testing found that both strains in March and July were different enough to indicate true refraction, not relapse.
According to the team, the genetic sequence showed that the first infection was caused by a close strain occurring in Wuhan, China, and the second infection was caused by a variable that reached the U.S. through Europe.
Corresponding author Dr. Jason Goldam, an infectious disease specialist at Swedish Medical Center, told the Seattle Times that after publishing the findings – which are yet to be peer-reviewed – the team is investigating more potential cases of reinstatement.
‘It’s not uncommon, this will happen, because we know that immunity to other respiratory infections like the flu is low,’ Goldman said.
“But I was a little surprised to find him in my own hospital, and you still don’t know what level of immunity you need,” he said.
Scientists believe he may have been re-infected because his immune system was compromised during the initial illness.
‘This is something about the patient’s immune system that isn’t working really well,’ Goldman said.
U.S. There are two other well-known cases in which patients have been infected with coronavirus twice.
The first is a 25-year-old Nevada man who fell ill with a mild illness in April and then tested positive again in June in a more serious case.
Another is a 42-year-old male clinician working at a military hospital in Virginia who tested positive in March and then again in May.
Recently, an 89-year-old Dutch woman became the first person in the world to die after being infected with the virus.
