  • Data from Sunday, Spain adds 674 deaths from coronavirus in the last 24 hours and marks a downward trend

A few days ago, the Imperial College of London, an advisory body to the WHO, published a mathematical estimate that calculated that 15% of Spaniards, about seven million people , would have already been infected with Covid-19 and therefore would be immunized against the coronavirus.

The head of the Health Alerts Area, María José Sierra, who replaces Fernando Simón as head of the Emergency Committee, has referred to this study at the press conference on Sunday when asked about the immunization that could already be in the population Spanish. After validating the figures , he has announced that, to refine these data, Spain is already preparing a seroprevalence study to find out the number of people immunized, although he has not given much more details of how it will be carried out.

A similar study would force massive antibody detection tests , which would be different from the rapid virus detection tests that have been discussed these days.

The tip of the iceberg

To understand what these numbers would entail, the journalist from the Data section of EL MUNDO Marta Ley explains that the numbers of infections that come to us every day are the tip of the iceberg . In the case of the iceberg, it is a matter of densities and volumes to calculate the size of the part that we do not see. With the coronavirus, it takes a little longer and a seroprevalence study like the one announced by Sierra would be key.

Imperial College London calculated that in Spain there could be between 1.6 and 18.5 million infected, which has translated into about seven million. The fork is quite wide, but the lower option indicates that less than 10% of cases are being detected , according to these estimates. This has a positive reading: if so, the case fatality rate that we know, above 10%, would be much lower than the current numbers indicate.

You can hear more about the confusion that exists regarding the data of this coronavirus crisis in this podcast:

The death toll in Spain is beginning to breathe. The deceased have increased by 674 people in the last 24 hours, according to data offered by Health this Sunday. This figure is lower than the one offered on Saturday for 809 victims and is the lowest in more than a week. The total number of deaths in Spain from coronavirus is 12,418.

ICU admissions have grown more intensely than the day before, when they totaled just over a hundred. This Sunday there are already 6,861 admitted to the ICU compared to 6,532 registered yesterday, although these figures are somewhat misleading since some autonomies report the accumulated income in the ICU since the start of the epidemic and others only those currently admitted.

María José Sierra has received the new data clinging to that "ray of hope" that she was already talking about on Saturday. "The increase in cases is around 5% and has been decreasing. In the increases in cases of hospitalized patients, we also observed a certain decrease. In most of the autonomies, hospitalized patients are less than in the previous day. Discharges already represent 29% of the total, "said the head of the Committee.
