Challenge continues to find accurate coronavirus antibody tests

  Challenge continues to find accurate coronavirus antibody tests Finding out who has been exposed to the coronavirus has been identified as a key to reopening the country. But there are problems. The WHO said there's no guarantee of immunity after infection but here in the U.S., medical experts overwhelmingly agree that the antibodies that remain give some level of protection. "So the tests that we have now on the market ... Don't tell you individually whether you have the neutralizing antibodies, whether you have the antibodies that can prevent you from getting an infection again," CBS News medical contributor Dr. David Agus said.

Data regarding COVID - 19 in pregnancy are limited; according to current information, presenting signs and symptoms are expected to be similar to those for non-pregnant patients, including the presence of fever. Other considerations that may guide testing are epidemiologic factors such as the occurrence

The study distinguishes itself from past Covid - 19 research by using seroprevalence data, meaning While it may seem like bad news that the virus could be that much more widespread on a global level — which is what the study concludes — it presents several positive factor including the fact that the

Encouraging news. A study by the Institut Pasteur and the CHU in Strasbourg indicates that one month after contracting the new coronavirus, patients still show antibodies and therefore signs of immunity. The tests were carried out on 160 caregivers of the Strasbourg hospital who were reached by covid-19 in mild forms, reports France Inter .

"Antibodies have been found in almost all of them: 159 out of 160," commented Professor Arnaud Fontanet of the Pasteur Institute, to the radio. “More interestingly, we were looking for neutralizing antibodies which we know are protective against, for example, reinfection. And there, from a month, we find in 98% of people who had been infected with SARS-CoV-2. These results are indeed good news, ”he added. These results indicate that patients would therefore be protected from possible reinfection.

The World Health Organization is warning that people who have had Covid - 19 are not necessarily immune by the presence of antibodies from getting the virus again.

Herd immunity hopes dealt blow by report suggesting only 2%-3% of people have been infected.

However, doubts remain about the duration of the immunity, which could last "from a few weeks to a few months", according to the scientists. To find out more, they will have to retest the patients. France Inter specifies however that France is far from the collective immunity which could allow the epidemic not to start again. Only 10% of the inhabitants of the red zones would have been contaminated and 2% in the green zones. Far from the 70% needed. But this news of effective immunity thanks to antibodies is also a good indicator to take into account in the search for a vaccine against covid-19.
