Coronavirus 19 in Spain during summer 2020 its behavior and climatic factors.

The evolution of the coronavirus is studied in Spain and the Valencian Community during summer 2020. The maximum number of infected coronavirus / day in this period was registered in mid-September, with a peak value of 14,389 in Spain and 960 in the CV, the increase Contagions began at the end of July at the end of the de-escalation and normality began in this stage contagion and community transmission caused by the action of human activity begins. The values ​​of contagions / day at the end of August reached 9779 for Spain and 670 for CV. In the month of September, the level of infections / day increased from 10476 to 14389 in Spain and from 540 to 960 in the CV. On 9/30 a total of 31,791 deaths were reported in Spain and a total of 769,188 contagions. The effect of temperature in this period did not follow the same trend in Spain as in China, in this stage temperatures rose but due to the high community contagion the natural evolution of the coronavirus was affected and it developed with greater intensity. It is recommended that more scientific and technical controls be used in the eradication of the virus and that one learn from the mistakes made. Juan G. R., Juan P J. A y Juan G. R.

The first coronavirus outbreak in the world originated in the city of Wuhan, in the Chinese province of Hubei on September 16, 2019, according to Chinese information sources, then it spread to different Chinese provinces and later gradually to different countries in Asia,  Europe, America, Africa and Australia.

At the end of December 2019, the virus began to spread through France and Italy, later, starting in January; it spread through different countries of the European Union, according to European information sources. On February 24, 2020, it was when the virus appeared on the Spanish peninsula according to information sources in Spain.

The WHO publishes its first part on epidemic outbreaks related to the new virus on January 5, 2020, a technical publication of reference for the global research and public health community and the media. The director general of the World Health Organization (WHO), Tedros Adhanom, declared on Wednesday, March 11, that the coronavirus covid-19 goes from being an epidemic to a pandemic.

The Pangolin is the mammal that could transmit the coronavirus in China according to research by the University of South China and is considered the intermediate carrier of the new strain of coronavirus.

The behavior of the coronavirus worldwide according to international information sources, the media and public health in different countries is as follows: 01/30.WHO declares a public health emergency.

03/13.The WHO assures that Europe is the new epicenter of pandemic.  04/28. The US exceeds one million registered coronavirus cases. 05/22. The WHO places South America as the new epicenter of the pandemic. 06/28. 10 million infections and half a million deaths are reported worldwide. 09/24. The WHO reports that the contagion by coronavirus in the world evolves very quickly, there are already 31.7 million infected and 975,000 deaths. 09/29. The WHO reports that the contagion by coronavirus in the world is 33.3 million infected and 1 million deaths.

Scientists believe that health authorities should take into account airborne transmission as part of the risk of spreading the virus, 8/7. The World Health Organization acknowledged that there is growing evidence that the coronavirus can be spread by small particles suspended in the air. It is more important to be in ventilated places than in closed places since the coronavirus can be spread by the small particles contained in the air, according to the New York Time News.                                                                                                                                                                     In China, 4 climatic zones predominate, two to the west: The Himalayan heights and dry climate deserts in the middle latitudes, 2 to the east: humid continental climate to the north and humid subtropical climate to the south. Wuhan located on the banks of the Yangtze River is the center of the epicenter of the virus and is between these two humid climates, near to the subtropical climate.

Asian scientists have investigated that in the conditions of China the temperature and relative humidity can influence the spread of the coronavirus: the low temperature favors the development of the virus, for each degree that the temperature increases it contributes to its reduction, when the humidity relative rise makes its transmission difficult, if the relative humidity drops the spread of the virus is greater.

On the other hand, there are studies on coronaviruses that report that high temperatures do not affect the spread and transmission of the virus, these investigations were carried out in 144 regions of the world until 03/27/2020, according to the Canadian Medical Association Journal.

The results of the study make a comparison of the evolution of the coronavirus in Spain and the Valencian Community during spring 2020, the statistical data were taken from sources of information reported by: The Ministry of Health of Spain and the Ministry of Health and Public Health of the Valencian Community and sources of news of the Spanish radio television and of different information media of newspapers of the country and of newspapers of information of the Valencian community in which the most used were El Desmarque and the Provinces. The climatic data were recorded from daily information sources of climatic stations of the State Meteorological Agency – AEMET

The number of maximum infected with coronavirus in the spring was on March 25, with a peak value of 9630 / day in Spain and 449 / day in the Valencian Community, then from the month of May contagions began to decrease due to the effect of confinement and the increase in temperature, with values ​​in the month of May between 1887-187 contagions / day for Spain and from 164 to 44 / day for the Valencian Community, reaching the minimum values ​​in the month of June with values ​​between 177- 99 / day for Spain and from 39 to 11 / day for the Valencian Community, Spain registers 248,970 contagions and 28,355 deaths at the end of June, the CV registers 18,339 contagions and 1,475 deaths during the spring of 2020, according to Juan and collaborators.

Since the start of the de-escalation of Phase-0 on May 4 until the end of the de-escalation that ended in early July, only 60 days have passed, with Phase-3 being the longest, the previous phases from 0 to 2, they had a very short duration from 1 week to 2 weeks see table No. 1. A short-term de-escalation caused that after 3 weeks the community contagion began to manifest itself, which after a short time became a community transmission of great intensity with values ​​of infections / day of 5423 in Spain and 238 in the Valencian Community in mid-August and later at the end of August it reached values ​​of contagions / day of 9779 for Spain and 670 for CV. In the month of September, the level of contagions / day increased from 10,476 to 14,389 for Spain and from 540 to 960 for the Valencian community. The peak of maximum contagions / day during the summer was 14389 for Spain and 960 for CV; see the month of September in Table Nº 1. On 9/30, a total of 31,791 deaths were reported in Spain and 1,643 in the CV, a total of 769,188 contagions in Spain and 40,686 in the CV. During the summer 90 observations were made, but only 20% of them are reflected in order to easily interpret the results.

The temperature on this occasion did not follow the same trend in Spain as in China, in the summer period the temperatures increase but due to the high community contagion produced largely by the action of human activity, the natural evolution of the coronavirus was affected and this developed with greater intensity. Relative humidity did not follow the same trend since Wuhan has a humid climate and in Spain annual rainfall is around half of that which falls in that area. At the end of June the des-escalation ended and the summer began, but the coronavirus in this stage reacted differently, it had another behavior because community contamination and the spread of the virus began due to the action of human activity, despite the fact that the Ministry of Health of the country and of the Communities make the necessary recommendations regarding the mandatory use of masks, respect the distance between people and limit the capacity of public and private places to a minimum.

We recognize the effort made by the Spanish State and the different Communities of the country in the control and reduction of community pollution and the transmission of the coronavirus, as well as the economic pressure that the country, businessmen and communities have to leave the problem and to return to normality but it is necessary to act with prudence and moderation, to learn from the mistakes made.

It is worth noting the great effort made by doctors and health personnel in saving the lives of patients and being able to cure them in time. Many doctors and health personnel at all levels have left their lives in such noble commitment and continue in the daily fight for the reduction and extermination of coronavirus 19. At this stage there were still many young and old people who did not respect the recommended measures, there were more than 15% who continued to challenge the coronavirus despite the fact that in September the average number of infections / day exceeded 11,000.

The coronavirus is also more active in population centers with more inhabitants, as it generally happens in other more populated regions of Spain: Madrid, Catalonia, Andalusia and other Communities with smaller population centers but with a higher rate of infections per 100,000 inhabitants as in Navarra. In the Valencian Community there are 3 provinces and the most affected is Valencia, the one with the largest population center. Community-based coronavirus contagion has different origins: social, family, work, leisure, vacation and extra-community, the most frequent being of social origin.

The coronavirus responds to different environmental conditions: the age of the people, the large population centers, the excessive activity of the behavior of human beings, the climatic factors and a planet that is increasingly polluted than humans do, animals and plants are more vulnerable to attack by different pathogens.

Viruses, like all living beings, adapt to different conditions of the environment that surrounds them and these are becoming increasingly harmful, so it is recommended that different countries finance more investments in virology research, virus genetics and behavior. of the same before the different climatic conditions, since the virus can mutate and become more harmful, creating more unfavorable conditions to the human race, it is also necessary to reduce greenhouse gas emissions into the atmosphere and environmental pollution of land, surface waters, underground waters, seas and oceans. It is essential that man respect the principles and laws that govern nature and the world, that we learn to live in harmony with the environment that surrounds us, otherwise we will cause the gradual destruction of humanity and the development achieved.

The answer on how to combat the coronavirus must be sought in a more scientific projection and a broader knowledge of the behavior of the coronavirus in each situation and time of year. It is necessary to achieve a common consensus and economic, political and social support from the different groups that comprise it, in order to achieve a more effective unitary front committed to the definitive eradication of the virus.
