Can people get coronavirus only one time? The World Health Organization has rejected the theory of people only being able to catch coronavirus once, and also suggested that society be reopened based on this supposed immunity.
The UN agency stated in a scientific report dated Friday that the view that a one-time infection could lead to immunity remains unproven and therefore unreliable as the basis for the next phase of the world pandemic response. The detection of SARS-CoV-2, the SARS-CoV-2 virus that causes COVID-19, may be the basis for an ‘immunity Passport’. There is currently no evidence of second infection protection from people who have recovered from COVID-19 and have antibodies.
The statement comes days after Chile announces that it will commence the issue of immunity cards that effectively act as passports that allow travellers to make certain that they have recovered from the virus at airports. Similar ideas have been expressed by authorities and investigators in countries like France and the UK, while some US officers, such as Los Angeles Mayor Eric Garcetti, have referred to it as a possible factor in a strategy for reopening.
The concept for such a card is based mainly on the assumption that the person can contract the coronavirus only once before the necessary antigens are developed to combat it. This premise underlines another common theory: the idea, known as herd immunity, that transmission will slow and decrease even for those who have not yet been infected if enough people have been infected with coronavirus and therefore immune.
However, these ideas largely depend on the assumption that one can’t get a second coronavirus — an idea that world health authorities have already stated that leaders shouldn’t rely on. The WHO stated Friday: There has been no study evaluating the immunity of future human infections due to antibody SARS-CoV-2.
Moreover, the data of the early COVID-19 hot spots in the world, such as South Korea and China, have revealed that an increasing number of patients recovering seem to have suffered a recurrence.
By mid-April, the health authorities in Korea reported that a second time after a positive test just over two per cent of patients recovered in the country was again in isolation. In Wuhan, China, there are data from several inhabited quarantine facilities which shows that about 5 to 10 per cent of patients decried to have “recovered” have tested positive again for observation after their hospital discharge.
Whether it is a sign of a second infection, a reactivation of the remaining virus in the body or the result of a failed antibody test is unclear. It is unclear why that is happening.
Decades of antibody tests with varying degrees of reliability and accuracy are already available for the novel coronavirus. House Democrats have launched an investigation to determine whether antibody tests should be implemented by the Food and Drug Administration, according to CNN.
“To ensure the accuracy of the ‘immunity passports’ or’ risk-free certificates,’ not enough evidence exists at this moment of the pandemic” warned the WHO.
“The use of these certificates may thus increase the risk of continuous transmission,” says the people who assume that they are immune from a second infection because the results of the test have been positive may be ignored by public health consultations.
