Health has published this Friday the data about the evolution of the pandemic that, due to the new outbreaks, continues to add infections in the ascending line. The coronavirus is being the main protagonist of the year 2020. Since its appearance in China, in November 2019, it has shown its high rate of infections and arrived a little more than four months ago in Europe, being Russia, the United Kingdom and Spain are the three countries most affected by a highly contagious virus that has gone from an epidemic to a pandemic as recognized by the WHO.
The data of deaths with date of death in the last seven days is 1,341, while the total death toll is 42,619, 328 more than on Thursday, last day of update. Regarding the positive by PCR, this Friday 15,156 infections have been added to the historical series, of which 6,021 have been dated in the last 24 hours. In total are 1,556,730 infected in Spain. In addition, the Health data shows that the Cumulative incidence stands at 168 cases per 100,000 inhabitants in the last seven days.
Madrid is the community with the most new positives in the last 24 hours, 1,131, ahead of Catalonia, with 832, while the Basque Country adds 821, Galicia 689, Andalucía 522 and Aragón 392. The data in Spain continue to rise, outbreaks continue to appear throughout the country and infections could get out of control again.
What is the peak of infections?
It is one of the key concepts and the most repeated phrases throughout these days. When the peak of infections is reached, the efforts to end the virus will intensify and that light will be seen at the end of the tunnel. One of the positives is that Spain has as references China and Italy, the two countries that suffered the COVID-19 hit before.
The first case of coronavirus in the world dates from November 17, 2019 and it was a 55-year-old man living in Wuhan (Hubei), patient zero. From that date, China took 116 days to reach the peak. A peak that reached on March 12, that is, almost four months later. The United States is the country with the highest number of infected and deceased in the world. It already has more than 12 million cases and more than 258,000 deaths. India, with more than 9 million infectedIt is the second country with the most infected, to which more than 132,000 deaths are added. Brazil, for its part, is the third country with the most infections in the world, with more than 5.9 million positives. In addition, it adds more than 168,000 deaths.
What is the epidemiological curve?
Without a doubt, this is another of the key concepts of the disease. The epidemiological curve is a graphic representation that gives information about the pattern of the pandemic and through it its evolution can be observed. It measures the number of cases (in this case of the coronavirus) during a certain number of time.
Fernando Simón, director of the Center for the Coordination of Health Alerts and Emergencies, explained it in a didactic way: “When we have an epidemic we wait for the cases to start and progressively affect the population. When the critical mass of the population disappears, we expect that curve to go down. The goal of early detection is to act early to prevent the curve from following a pattern in which cases do not increase as much and the peak is reached early in order to eliminate a large part of the epidemic. “
Actually, both the peak of infections and the epidemiological curve are directly related. The objective is that the line of that curve is not so vertical, but that it tends towards a flat mountain. When that curve sees its trend reversed, after marking its highest peak, that is when the peak of infections will have been reached. From there, the number of infections each day should begin to decline day after day.
Although currently, the coronavirus is advancing in Spain with a curve very similar to that of early March. Specifically, the week from 5 to 11 of that month, shortly before the state of alarm was decreed. The big difference is that New cases are being detected better and faster, allowing authorities to act sooner.
Cases in the autonomous communities of Spain
The most affected autonomous community it’s Madrid again, where there are already more infections confirmed by PCR (339,405) what in Catalonia (292,348). Madrid is also the community that registers more deaths (11,201). Catalonia, for its part, counts a total of 7,495 deaths. These regions are followed by Andalusia (212,439 positives and 3,527 deaths), Castilla y León (114,549 and 4,293), the Basque Country (91,404 and 2,338), and the Valencian Community (91,912 and 2,168), are behind all of these, but add cases to a similar speed.
