Official statistics indicate that about 250 thousand cases. However, experts believe that 90 percent of the cases were not identified by the healthcare system of Spain, this means that the real number of survivors of the Spaniards could reach over 2.5 million people (about 5 percent of the population). If we take only the confirmed cases, the health workers will make up a quarter of all detected cases.

However, a high percentage COVID-19 observed in other professions that did not stop the work during the period of quarantine. So, in an environment of social workers (in nursing homes, for example), it was 7.9 per cent for policemen and firemen of 6.3 percent.

the Study, which was presented to the public, has been ongoing for several months. Experts are studying what percentage of the population has antibodies to coronavirus. We are talking about the immunoglobulins IgG and IgM. The presence of the first indicate that a person has been infected but are now recovered. The second appear in the body for 6-7 days after onset of the symptoms, they are produced first in response to the virus.

According to experts, based on a survey of tens of thousands of people from different parts of the country, at the moment the antibodies produced 5.2 per cent of Spaniards. This means that 95 percent of the population still vulnerable to the virus, said the Director of the Institute of health Carlos III Raquel Lotti. According to epidemiologists, to ensure that the population acquired immunity, it is necessary that antibodies to the virus had at least 60 percent of the population.

However, absence of antibodies does not mean that these people are not protected from the coronavirus, the Director of the National centre of epidemiology, Marina Pollan. The disease is still poorly understood, and people may have to it immunity at the cellular level. In favor of this theory says that sometimes the test results indicate that a person has been infected, cured, but the antibodies in his body is not found.
