The coronavirus in Spain: maps and latest data on outbreaks and their evolution

Data from the Ministry of Health updated on December 24, 2020.

1) Accumulated incidence in 14 days, by communities

What are the autonomous communities most affected by the pandemic at this time? The following map shows the cumulative incidence (AI) today in each community. This is the number of confirmed COVID-19 cases in the last 14 days in relation to the population of each territory. Click to see the detailed data (total cases, accumulated incidence and deaths, total and per 100,000 inhabitants).

2) How is the trend?

In addition to the total data (those accumulated since the beginning of the pandemic) and the AI, the following table is useful to know what the trend is like in each community. We have calculated the number of cases in the last 14 days per 100,000 inhabitants compared to those diagnosed per 100,000 inhabitants in the previous 14 days. In this way we can know if the cases are going up, down or remain stable in each community.

3) The weekly evolution of the epidemic

To show how the epidemic is progressing, we show the evolution of daily cases as well as deaths, hospitalizations and ICU admissions during the last 7 days for the entire country. To avoid possible delays, the figures are calculated by notification date, so that new cases, admissions and deaths notified by the autonomous communities are shown. The dashed line marks the end of the state of alarm and the beginning of the ‘new normal’, on June 21.

How is the epidemic evolving now?

4) Evolution of new daily cases

How many cases are we detecting now and how many do we detect at the beginning of the epidemic? The graph below compares the number of new daily cases by symptom onset date since February 1. To avoid detection peaks on a specific day, the average of both figures including the last 7 days has also been calculated.

The figures for the last week may be underestimated since many cases that started symptoms in that period may not have been detected by the health authorities.

5) The curve of cases and deaths in each community

The records of the Ministry of Health indicate that the peak of cases of the first wave arrived the week of March 23. The sprouts and waves of autumn, however, have not come at the same time in all communities.

In the graph below, you can explore the number of people who were diagnosed with COVID-19 with a test each day in each autonomous community, as well as the number of hospital admissions, ICUs and deaths affected with the virus , by date of death. The data is shown with the daily average of the last week. In addition, it is included what percentage the figures of the last week represent with respect to the maximum (the peak) that each community has reached. Data from the last days may be underestimated due to the delay in notification, especially of hospitalizations, ICU admissions and deaths.

6) Cumulative incidence, by province

To see how controlled the pandemic is and to identify possible outbreaks, the following map shows the main variables to see the situation of the epidemic in each province: if the cases are going up or down, the incidence of cases per inhabitant in the last two weeks, the total number of cases and the incidence of the virus compared to its population.

These data are published by the Carlos III Health Institute (ISCIII) through the National Epidemiological Surveillance Network (RENAVE) and it does so for date of onset of symptoms or the date of diagnosis for asymptomatic cases. As in the previous graph, the data from the last week may be underestimated since the date of onset of the symptoms is taken into account and they take a few days to be diagnosed from the contagion.

7) Confirmed deaths in the last week

The following table shows the total number of people who died with COVID-19 and the deaths reported in the last week. We have calculated the number of deaths per 100,000 inhabitants in the last 7 days. The death figures only include the deceased with a positive in an analytical test. That is, the deceased with Covid-19 who died without a positive test are not included and it must be taken into account that the mortality figures of the last week they have significant delays.

8) The incidence of the virus in each community

To find out the degree of penetration of the virus compared to the number of inhabitants, we have calculated the rate of confirmed cases and the number of deaths in each autonomous region per 100,000 inhabitants. Confirmed cases refer to those identified by PCR, antigen or antibody tests — in the latter case, only those carried out after May 11 with compatible symptoms are counted.

9) Healthcare situation

Are the hospitals saturated? From the 20th of August The Ministry of Health includes in its updates data on the situation of the healthcare capacity in the hospitals of each community. Thus, it is possible to know how many patients with COVID-19 are admitted, both hospitalized and in the ICU, in the last 24 hours. And also how many discharges were made on the last day (Health has been since May 18 without providing the number of people recovered).

10) Evolution of positivity and diagnostic tests

Monitoring the number of tests compared to the percentage of them with a positive result (positivity) is an indicator of the diagnostic effort being made to detect new cases. When the number of tests is high and the positivity is low, the risk of a significant number of infected people not detected by the health system remains low, and therefore the calculated incidence is reliable. On the other hand, if the number of tests is low and the positivity is high, the incidence could be underestimated. The following graph shows the evolution of both indicators in each autonomous community. All the CCAA show data from PCR tests and since the end of October many are including antigen tests in their positives.

11) Diagnostic tests performed

As of November 5, the autonomous communities had notified the Ministry of Health that more than 12.6 million diagnostic tests had been carried out. The following table shows the number of PCR tests (which measure the presence of the virus in the body) and antibody tests, the so-called ‘rapid tests’, carried out by each community since the beginning of the epidemic in our country and per 100,000 population.

Some keys about the data

Due to the successive changes in the form of notification of the data in the reports of the Ministry of Health, some keys should be taken into account:

Since May 18, the Ministry of Health has not provided the number of people recovered.

Also from that day on, Health stopped including the number of cases detected by antibody tests in its reports. Thus, the total cases to the cases detected with PCR test.

On Monday, May 25, the daily updates of the Ministry of Health changed again. This change is due to the fact that on May 11 the new strategy for the diagnosis, surveillance and control of the pandemic came into force, by which the autonomous communities must notify the cases to the Ministry individually.

As a consequence of this modification, the report warns, they may appear “discrepancies with respect to the data of total cases previously reported”. “This discrepancy could persist for up to several days.”

At the moment, and until the Ministry of Health publishes the corrected and updated data series, it is not possible to see the daily evolution, raw, of the advance of the coronavirus in Spain (confirmed, deceased and recovered cases), since the series has been truncated. For this reason, we have removed some graphics that until now we included in this piece. As the CCAES corrects and updates the historical data, we will add new graphs and data analysis to our information.

He August 19, the Health Department began to include a new piece of information in its daily reports: the number of PCR tests carried out in each community (until then, this information was sent in a weekly report).

The next day the 20th of August, Health added a new information panel in its daily updates, that of the ‘Situation of care capacity and COVID-19 activity in hospitals’, broken down by autonomous communities. This panel includes data on the total number of COVID-19 patients admitted and in the ICU, the percentage of hospital bed occupancy by patients with the disease, the number of admissions and discharges with COVID-19 in the last 24 hours. Health did not provide data on people recovered since May 18 (150,376 in total).
