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 in Europe just over two months ago, being Spain and Italy are the two countries most affected by a highly contagious virus that has gone from an epidemic to a pandemic as recognized by the WHO.

The total death toll this Wednesday stands at 27,118, which is one more death than yesterday. The number of deaths with a date of death in the last seven days is 39, four more than on Tuesday, so there have been at least four deaths in the last 24 hours, which could be more considering those with more than one week old, they abandon the count. The Ministry of Health does not report the cases of each day, only of the last seven days. The positives for PCR do continue to be reported for days: there have been 231 in the last day, a slight rebound compared to 194 yesterday; in total there are 236,769.

The Community of Madrid, which Phase 1 of the de-escalation began this Monday, has added 81 new positive cases and six died in the last week. Catalonia, whose regions that were still in phase 0 have also started phase 1 this past Monday, has registered 93 new infections and nine died in the last week.

The data in Spain is stabilized, experts say, but it is still missing to return to normal. The alarm state It is currently extended until June 7, after the fifth extension of the state of alarm was approved this Wednesday

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 contagion is reached, efforts to end the virus will intensify and that light will be seen at the end of the tunnel. One of the positive aspects is that Spain has as references to China and Italy, the two countries that suffered the coup of COVID-19 before.

The first case of coronavirus in the world dates from November 17, 2019 and he was a 55-year-old man living in Wuhan (Hubei), patient zero. From that date, China took 116 days to peak. A peak that reached March 12, that is, almost four months later. The United States is the country with the highest number of infected and deceased people in the world. It already has almost 1.72 million cases and more than 100,000 deaths. Brazil, with more than 395,000 infected It is the second country with more infected, to which it adds more than 25,600 deaths. Russia, for its part, is the third country with the most infections in the world, more than 371,000 positive. In addition, it adds almost 4,000 deceased.

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 Coordination Center for Health Alerts and Emergencies, explained it in a didactic way: “When we have an epidemic, we wait for the cases to start and gradually 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 where cases do not increase as much and the peak is soon reached to eliminate much of the epidemic. “

In reality, both the peak of infections and the epidemiological curve are directly related. The goal is that the line of that curve is not so vertical, but tends towards a flat mountain. When that curve sees its trend reversed, after marking its highest peak, it is when the contagion peak will have been reached. From there, the number of infections each day should start to decrease day after day.

Cases in the autonomous communities of Spain

The Autonomous Community most affected is still Madrid, where there are more infections confirmed by PCR (68,266) and more deaths (8,691), followed by Catalonia (57,749 and 5,583) and Castilla y León (18,631 and 1,922). Castilla-La Mancha (16,984 and 2,945), the Basque Country (13,504 and 1,424) and Andalusia (12,609 and 1,404) lag behind all of these but add cases at a similar speed.

At what point in the coronavirus crisis is Spain?

Spain stands on the 75th day of the state of alarm, which entered into force on Saturday, March 14. However, its expansion has been approved in Congress several times, in sections of 15 days; it is currently in force until June 7, after the last extension agreed for another 15 more days.
