Researchers who have sent finger is home to more than 365.000 people in England and graduated randomly tests found that more than 26% Covid-19 antibodies is the wrong decision for three months.
"We observe a significant decline in the proportion of the population with detectable antibodies through three rounds of country surveillance, using a self-administered lateral flow test, 12, 18 and 24 weeks after the first peak of infections in England," the team wrote in a pre prior version of their report, released before parity review.
"This is the one that belongs to immunity 6 to 12 months by the decrease of the time Coronaviruses with information about emerging and infection-2-Cov SARS, which is then detected by a decrease in the muscle followed by a step to win '
Monday published a study by Imperial College London and Ipsos MORI market research company. In the study beginning in June, with 6% of those tests were a response to coronavirus and Clostridium perfringens antibody, were reported. In September, as did 4.4% of them. For health and rates stayed about the same.
The results showed that of those who are not necessarily indications that the studies also confirm that the man in front of Covid 19, there are those who are more likely to be detectable of the elements more quickly, not destroy, the more serious faults.
19, of the elements with respect to the one who is least of men, who were left after them there was a greater than 75 Covid slowly recovering from a loss of consumption, the researchers have found.
Some infections, such as measles, which cause sterilizing it does. Once infected people, the elements must be found for many years in many diseases.
The study has a time limit. For it is not by the same people to the precedents and other remarks of the time. It is possible that those who had been exposed to the coronavirus that are less likely to have a number to call them, investigators said.
"We will not know whether they are in danger of reinfection in the nation, however, the virus that causes this, I leave the COVID 19, but it is necessary so that everyone continues to follow the guidance, that is, to reduce the danger be brought to him, and, with the other," she added a guard, who is in the labored at the university.
The UK's Health Minister, Lord James Bethel, a study called "critical part of the research" may not only help to inform the British government right to take action to control the spread of Covid-19.
"When I know everyone It is also important how to get it - this study to help in the fight against the virus, but tested positive for antibodies, it is not immune to Covid 19, said in a news release to." Whatever is the effect of the antibody test; all must continue to comply with government guidelines removed from the social, personal and isolating getting to test if you have symptoms and always remember hands, face your Space ".
Dr. Hoyen claudia, who specializes in pediatric infectious diseases of hospitals to the University of London, the study of thought that it is interesting and he exhorts them, he reminds us, at least, where the elements of the law of nature, and that there, as He is another Coronaviruses coronavirus acts. Such as a cold, antibodies will not decrease because people can get a cold more than once. That, too, with a cold, robust immune system is the people's, typically the youngest of the people, I do not see that the time is typically in the older people, there is a drop in the immune system of the elements.
"This is the first part of the puzzle is actually from the really like this gives us an indication of the study is to say, that in this way, it seems to stick around the elements of these, and not to all of them," he said Hoyen. "But, at least in this case, where the virus is acting like a race to predict, which is good for all, for this was an off the wall." Hoyen study and said: "cements what we're going to be for awhile while."
"I know what we're all hoping that at the end of the first, but just think what he wants," he said.
"I sooner we resolve ourselves to the fact that what we do, so we can get and move on. These data clearly show has elements that go away. So just because it was not immediately you immune, it also means that you can in turn be contagious . "
