In the first confirmed case of its kind in the United States, a young Nevada man has been re-infected with the CCP virus, the virus that causes COVID-19, with the second wave of illness far more severe than the first, a recent study shows.
At the end of May, he consulted at an urgent care center with his prior symptoms, as well as fever and dizziness. He was hospitalized five days later with shortness of breath, was given oxygen, and again tested positive for the CCP virus in early June.
"The second infection was symptomatically more severe than the first,” the case study authors wrote.
Since the COVID-19 outbreak first emerged in Wuhan, China, last year, only five cases of reinfection have been recorded out of more than 37 million confirmed cases. An Ecuador patient was the first recorded reinfection case where a more severe bout of illness upon reinfection was displayed.
The researchers said it is not clear why the Nevada patient displayed more severe symptoms upon reinfection.
COVID-19 ImmunityScientists are studying how the other parts of the immune system activate to fight the CCP virus. Antibodies are only one part of the body’s immune response, and over time, they wane naturally.
In examining COVID-19 immunity, some scientists are looking into other immune cells known as T-cells, which are produced as an immune response to molecules known as antigens, and can be programmed to tackle the same or similar viruses in the future.
The treatment was hailed by President Donald Trump as key to his recovery from the COVID-19. He pledged to make the monoclonal antibody treatment available to Americans for “free,” and vowed that the Food and Drug Administration (FDA) would quickly authorize the experimental drug.
