If someone gets a new coronavirus, heal and get sick again? At the end of April, Jin Korea announced that it had recorded a case in which people fell ill repeatedly. At the time, there was speculation as to whether it was not just a test error.
But now the World Health Organization has issued a scientific summary warning warns against relying on acquired immunity: Some states have presented full imunitn belts. You would blame the people who bothered her. Such a passport should allow the driver, for example, freedom of movement, because it would theoretically ensure that the virus does not follow. However, according to the WHO, this is also theoretical: At present, we have no evidence that people who are recovering from covid-19 and have relapses cannot get the disease a second time.
Most studies available to the WHO show that people recovered from covid-19 have antibodies against the SARS-CoV-2 virus. But some people have very few blood clots, suggesting that cellular immunity also plays a role, according to the WHO (PDF). And so far (until April 24) the day of the study has not assessed whether these antibodies actually occur in humans to prevent the type of infection.
According to the WHO, rapid tests that have patches in the patient’s blood must be further assessed to make it clear how accurate and reliable they are. (Even relatively accurate tests have a high percentage of falenches, as shown by our simulations.) Tests must show that they can distinguish new coronaviruses from six existing strains, three of which are relatively native to the population, first of all WHO.
The World Health Organization emphasizes that it is not against rapid tests: We support studies that use rapid tests, as these studies are important for understanding how infections are affected and what this affects. However, the fact that the presence of antibodies in the blood does not mean that the person cannot become ill with the new coronavirus. Relying on such a result could lead to further illness, warns the WHO.
Not only the so-called immune passports are hidden with immunity, but also the strategy of the so-called promo, which has recently been talked about in the Czech Republic. This requires that the population gradually develop a collective (medium) immunity. If this immunity were to be shown not to last for a long time, it would also jeopardize the functioning of this collective immunity. Until there is detailed information on how the immune response works and how long it lasts, any strategy that conceals immunity is uncertain.
