Immune protection suspected in first confirmed case of coronovirus reinfection in the US

Cleveland, Ohio – Researchers in the United States have confirmed a case of COVID-19 recombination, suggesting that people who recover from the disease may not develop immunity. The case is believed to be the first North American case of revision with COVID-19.

The 25-year-old Nevada man tested positive for COVID-19 in April and again in June, separated by two negative tests, according to a case study published Monday in the Lancet. The study stated that the man was infected with two different strains of coronovirus.

The study noted that the patient’s second fight of COVID-19 was worse than the first, requiring hospitalization and breathing assistance.

“These data have implications that SARS-CoV-2 can adapt in an individual with sufficient genetic dexterity to evade a natural immune response to re-establish detectable levels of infection,” the study noted .

This data has implications for future COVID-19 vaccines. This may mean that the initial performance of coronaviruses “is not the result of immune levels that are 100% protective for all individuals,” the researchers wrote.

The Lancet study stressed that COVID-19 re-construction is rare. Nevertheless, everyone, whether they had previously suffered from the disease or not, should take precautions to avoid infection.

The Lancet case study researchers, most of whom are based in Reno, Nevada, are not sure why the man became ill during his second illness. The study states that the patient has taken high doses of a more virulent version of the coronovirus or virus.

Another possibility is that the presence of antibodies in their bloodstream made the second infection worse; This phenomenon has been observed in other diseases such as dengue fever.

The Nevada case is the fifth confirmation of COVID-19 reinfection globally.

The first documented case of reinforcement was identified in Hong Kong in August.

Cases of other reinfections have been found in Belgium, the Netherlands and Ecuador. According to press reports, the cases in Belgium and the Netherlands showed no difference in severity of symptoms.

Researchers in the Lancet study noted that the Nevada case and other confirmed revision cases included patients with COVID-19 symptoms. It is possible, the study noted, that many infections and recombination occur among asymptomatic people, and are undefined.
