The experts of the World Health organization warned that, until now, the evidence has not shown that a person who is positive for antibodies to the coronavirus COVID-19 develop an immunity to the disease.
The statements were made by the director of emergency Mike Ryan and the expert Maria Van Kherkove during the press conference usual of the WHO.
The experts responded to a question on the decision of the Government of Chile, which announced that it plans to issue the first report cards of immunity” in the world for people who have recovered from coronavirus, so that they can return to work and normal life. Other countries, like the united States, also have mentioned the possibility of implementing these “credentials of immunity”.
“The countries must be very cautious at this time, we need to be very sure of what tests are the ones that will define the state of an individual, and there is a lot of uncertainty around what types of tests would be, and how effective they are,” said Ryan.
According to the expert, much of the preliminary information that reaches the WHO currently suggests that a small proportion of the population is hiv positive.
“There is an expectation that the immunity of collective has been reached and that the majority of the people of the society have already developed antibodies, and the overall evidence indicates otherwise, then a test of immunity would not solve the problem that Governments are trying to solve, and there are also serious ethical issues about it, using this technique, that needs to be addressed very carefully,” he warned.
Also you have to check how much protection they can give the antibody, said. “No one is safe from someone who has the antibody is fully protected from having the disease or being exposed back to it. In addition, some of the tests have problems with sensitivity, can give a false negative,” he said.

Ryan clarified that it is not that the World Health Organization is against these tests, but he said that there is still much work to be done to standardize them, to be sure that they are validated, are part of a coherent policy, and that there is a reason for public health to use them, and that they are not misused in any way.

“We will review what Chile wants to make or propose, as in other countries, and we will issue recommendations based on the science”, he explained.
Dr. Maria Van Kherkhove assured that the guide of the World Health Organization, which will be issued this weekend, will update as we get new information.
“There are many countries that are suggesting to use test serological quick to be able to capture what is for them a measure of immunity, but as Mike said, right now we don’t have evidence the use of this type of test demonstrates that an individual is immune or protected from a new infection” he reiterated.
The doctor said, that, however, what these tests can do is to measure the level of antibodies, which is the body’s response after one or two weeks after being infected with the virus, and the test can measure the prevalence of serological, that level of antibodies, but that does not mean that someone with antibodies will be immune.
“It is something quite confusing, there are many tests that are flooding the market right nowand this is a good thing, that are ongoing, but we have to ensure that they are validated, and that what they promise that they are measuring, whether it is really what you are measuring, so we hope to publish a guide that will be updated as we get more information,” he said.
