The Ministry of Health notified 4,341 new cases of covid-19 on Tuesday, raising the number of infections to 3,773,032 since the start of the pandemic, according to official statistics. It also computes 29 new deaths. The cumulative incidence continues to decline and stands at 92.25 cases per 100,000 inhabitants.
As for the situation by communities, this is uneven, but in most cases the map now paints increasingly lighter colors.
Regarding the accumulated incidence data, one of the greatest dangers is the implication it has on the health system. The collapse has been a possible scenario, the worst, but possible. That is why we must not lose sight of it.
The evolution at the national level is currently downward, both in hospital beds occupied by patients with coronavirus and in those found in intensive care units.
The daily data of the coronavirus in Spain
At present, according to
current coronavirus surveillance strategy, which came into force on May 11 and has been modified a posteriori, the cases diagnosed by an active infection test (a PCR or a rapid antigen test) are taken into account for the total count.
This graph shows the new cases reported by Health, that is, the subtraction of the infections reported each day by the autonomous communities compared to the previous day.
Since the beginning of July, the Ministry of Health does not report the data of the pandemic at the weekend, which is why on Monday there is a significant increase that adds the days not reported. There are also delays in the notification of cases by the communities. To correct for these variations, the graph shows an average of the last seven days.
When a person is exposed to the virus and becomes infected, they may or may not develop symptoms. Depending on the severity, she must be hospitalized and in the worst case, she may die. Since the beginning of the epidemic, those over 80 have been the age group most affected. The following graph shows this variable with the data collected by the National Epidemiological Surveillance Network (Renave) until May 10 and from May 11, when a new diagnosis, surveillance and control strategy came into force.
Some experts suggest multiplying the number of infected persons for March or April up to ten, due to the lower detection capacity that existed in those months, and this would imply that the fatality rate decreases. The death figure does not vary, showing an evolution with several waves marked above the average of recent years.
Days elapsed between infection, diagnosis and death
One of the data that shows the evolution of the pandemic is the time that elapses between when a person is infected, is diagnosed, hospitalized and, ultimately, dies. In the comparison between the first wave and the rest of the periods (second, third and fourth wave) it can be seen that the days between infection and diagnosis have been reduced by half and, on the other hand, from hospitalization to death elapse now twice as many days.
Data accumulated by communities
Day by day, except weekends and holidays, Health provides some new data on the coronavirus in Spain, which are summarized in the following table:
The first cases were diagnosed in La Gomera, at the end of January, and in the Balearic Islands, at the beginning of February 2020. With both patients already recovered, the virus manifested again in the country as of February 25. Later it would be known that the first victim of this epidemic died on the 13th of that same month.
The figures provided by Health every day come from the autonomous communities and are provisional in that the notification of cases may be delayed. Hence there were great
variations between these daily data and historical accountingmade available by the Carlos III Health Institute and that arrived, for example, in Madrid to the
11,000 more cases per day of those initially notified.
In a new scenario, that first history stopped being updated and after a few days without information, the Carlos III Health Institute
periodically publishes a new review of the data (also provisional).
The comparison with other countries
The coronavirus has generated different curves in the countries it has reached. One of the most effective methods to analyze the behavior of the covid, according to the experts, is through the comparison of daily deaths. A) Yes,
Although each country has a different way of counting them, it is more accurate than that of confirmed cases, which does not reflect the real number of infections (because its detection is not accurate). This graph shows the average of the last seven days of reported daily deaths (this average helps to visualize the trend because some cases are reported late).
It has been a year since China, the origin of the coronavirus, stopped being at the forefront of accumulated infections and now the United States, India and Brazil are the countries that agglutinate the most cases. In this sense, the data on infections per 100,000 inhabitants is interesting, which, beyond the different accounts existing in each country, serves to compare the situation between the different territories.
