A 25-year-old man in the US state of Nevada has contracted coronavirus on two separate occasions, according to a study in the Lancet Journal of Infectious Diseases, which showed that a patient became seriously ill after a second infection.
This is the first confirmed case of an American patient being re-infected with Covid-19, and the fifth known case reported worldwide.
A resident of Wash Shoe County, who has no known immune disorder or a history of significant underlying conditions, needed hospital treatment for a second positive test for Covid-19.
He has now recovered, although the case raises more questions about the possibility of developing a protective immune system against the coronavirus.
To date, more than .837.8 million people have contracted covid-1 cont worldwide, including 1.08 million related deaths, according to data compiled by Johns Hopkins University.
The head of the crisis at the WHO said earlier this month that his “best estimates” suggest that about 1 in 10 people worldwide may be infected with coronavirus, a significantly higher number than confirmed.
what happened?
March 25, The 25-year-old, Nevada’s second-largest population, experienced a wave of symptoms consistent with viral infections, including sore throat, cough, headache, ause bark and diarrhea, according to a study by the peer-reviewed medical journal.
He made the presentation at a community testing event organized by the Wash Wash County Health District on April 18 and tested positive for Covid-19 for the first time.
The patient’s initial symptoms were completely cleared on April 27 during isolation. He then continued to feel well and tested negative for coronavirus on two separate occasions on May 9 and May 26.
The 28-year-old experienced symptoms again from May 28 at this time including fever, headache, dizziness, cough, nausea and diarrhea.
On June 5, 48 days after the initial positive test, the patient became infected for the second time. His condition was found to be more “severe” in symptoms than at first.
He referred the doctor to the primary care doctor and pointed out the need for treatment in the hospital for shortness of breath. He later recovered and was discharged from the hospital.

Scientists said the patient caught the coronavirus on two separate occasions, rather than spreading the original infection after becoming inactive. This is because the genetic code showed “significant differences” between each type associated with each instance of infection.
“These findings suggest that the patient was infected by SARS-Co-2 on two different occasions by a genetically specific virus. Thus, previous exposure to SARS-Co-2 cannot guarantee complete immunity in all cases,” the study authors said.
They added, “All individuals, whether previously diagnosed as having COVID-19, should take equal precautions to avoid SARS-CoV-2 infection.”
To protect yourself, the WHO recommends maintaining a physical distance of at least 1 meter from others, wearing a mask, avoiding crowds, keeping rooms well ventilated, and cleaning your hands thoroughly and frequently.
Lancet said the patient had given written consent to publish the report, a policy waiver granted by the University of Nevada, Reno Institutional Review Board.
Secondary coronavirus infection
That second case of coronavirus was thought to be milder than the first, although it is not yet clear why the Nevada patient became seriously ill a second time.
Reports of secondary coronavirus infections in Hong Kong, the Netherlands and Belgium all said they were no more serious than before.
However, a man from Ecuador said the U.S. The case reflected to be more serious, but the case did not require hospital treatment.
