This week, for the first time in the world, a person was diagnosed with the coronavirus for the second time, after which the first case was reported in Europe and now in the United States.
According to Dawn News, so far in Asia, Europe and the United States, there have been cases of a second case of COD 19. Researchers have revealed that a US citizen has been infected with the corona virus for the second time in a study that Not published in medical journals.
The study, published online, found that it was confirmed by a 25-year-old man in Reno, Nevada, who tested positive for the virus in April, when it was mild to severe. Eventually, he fell ill again, which was very severe.
Christine Anderson, an immunology professor at Scripps Research, who was not involved in the study, told Reuters: 100% immunity is not possible. ”This week, experts at the University of Hong Kong confirmed the re-diagnosis of code 19 in a 33-year-old man, the first case of its kind in the world.
The man was first diagnosed with code 19 at the end of March and was able to defeat it in April. But several months later, in August, he was diagnosed with a different type of virus.
Experts from the Nevada University, Reno School of Medicine and the Nevada State Public Health Laboratory said in a study that they were able to prove that two different strains of the virus were identified in the American citizen. The chances of being infected again are very low, but the results do show that not everyone is protected from the virus for the first time.
"We don't know what the rate of recurrence can be and how it can change over time. To answer these questions, before conducting extensive research, we need to look at a single case of recurrence of code 19," he said. We cannot draw conclusions about the strength of the immune system and the future effectiveness of the vaccine.
In addition to Hong Kong and the United States, two such cases were reported this week in European countries, Belgium and the Netherlands. Mark van Ranste, director of Belgium's National Corona Virus and Rotavirus Laboratories, confirmed the case.
"We've proven, based on solid genetic evidence, that the woman has contracted code 19 for the second time," he said. "In fact, there are clear differences between the two different types of the virus and He said that the severity of the disease in the patient is mild while there are 2 more cases which may have been infected with code 19 for the second time, but further investigations are being carried out for confirmation.
On the other hand, Marion Copemans, a virologist at the Erasmus MC Department of Virology in the Netherlands, confirmed the disease again in an elderly patient, saying: Should be ready to watch the events of
"Patients are expected to be re-infected with code 19," he said. We know that once you are infected with the code, you are not immune to it for life. Being antibodies does not mean that you are immune to it.

It should be noted that the debate over being infected with the corona virus more than once has been going on for several months. Many people felt that they have been infected with the virus twice, but in-depth testing would be needed to confirm Yes, without which it is not clear whether it is a re-infection or the effects of being infected for the first time.
Research reports have so far indicated that most people who recover from the disease develop antibodies and T cells that play a role in protecting them from re-infection with the virus, which protects them from code 19 for some time. Can live
