A study in the Lancet Journal of Infectious Diseases found that a 25-year-old man in the US state of Nevada contracted coronavirus on two separate occasions. Shown, The patient becomes seriously ill after the second infection.
This is the first case in which a US patient has been re-infected with Kovid-19, and the fifth case reported worldwide.
A Washoe County resident, who has no history of immune disorders or significant underlying conditions, needs hospital treatment to test positive for Kovid-19 for a second time.
Although the case raises further questions about the possibility of developing a protective immunity against coronavirus, he has now recovered.
To date, more than 37.8 million people worldwide have been infected with Kovid-19, with 1.08 million related deaths, according to data compiled by Johns Hopkins University.
The head of emergency at the WHO said earlier this month that “Best predictions“It indicates that about one in 10 people worldwide is infected with coronavirus, which is far more than the number of confirmed cases.
On March 25, In a study by the Peer-Reviewed Medical Journal, a 25-year-old man in Nevada’s second most populous county experienced a wave of symptoms consistent with a viral infection, including sore throat, cough, headache, nausea, and diarrhea.
He submitted to a community testing program conducted by the Washoe County Health District on April 18 and tested positive for Kovid-19 for the first time.
The patient’s initial symptoms were completely resolved when he was alone on April 27. He then continued to feel better and tested negative for coronavirus on two different occasions on May 9 and May 26.
The 25-year-old experienced symptoms including fever, headache, dizziness, cough, nausea and diarrhea returning from May 28.
On June 5, 48 days after the initial positive test, the patient was infected with the virus for the second time. His condition was found to be “more severe” in symptoms than the first.
He was referred to a primary care physician and required hospital treatment for shortness of breath. He later recovered and was discharged from the hospital.

Scientists say the patient caught the coronavirus in two different cases, without bouncing back after the actual infection had subsided. This is because a comparison of genetic signals showed “significant differences” between each variant associated with each instance of infection.
“These studies indicate that the patient was infected with SARS-CoV-2 in two different cases by a genetically differentiated virus. Therefore, previous exposure to SARS-CoV-2 may not guarantee total immunity in all cases,” the study’s authors said.
“All individuals, whether previously suffering from COVID-19 or not, should take the same precautions to prevent SARS-CoV-2 infection,” they said.
To protect yourself, WHO Recommends Maintain a physical distance of at least 1 meter from others, wear a mask, avoid congestion, ventilate the rooms well and clean your hands thoroughly and frequently.
The Lancet states that the Reno Institutional Review Board, with the moral approval of the University of Nevada, gave the patient written permission to publish the report.
Secondary coronavirus infections
The second case of coronavirus was thought to be milder than the first, although it is not clear why the Nevada patient became seriously ill a second time.
Reports of secondary coronavirus infections in Hong Kong, the Netherlands and Belgium are not all more severe than the first.
However, one in Ecuador reflects that the US case is more serious, but this case does not require hospital treatment.
