Since the coronavirus pandemic broke out, one of the main issues at the global level has to do with the risk of contagion of coronavirus according to the season of the year. Now, scientists from the University of Veterinary Medicine in Vienna, Austria, have shed light on this matter. There are notable differences in the risk of infection in winter and in summer.
When is there a greater risk of contagion of coronavirus? In summer or in winter?
Alois Schmalwieser, the main author of the research, explains that the season of the year is one of the most influencing factors, and in summer the risk of contagion from Covid-19 is lower because the aerosols remain less time ‘floating’ in the air.
The aerosol sprays They are microscopic particles that are suspended in the air. When we sneeze, cough, speak, or simply breathe, we emit respiratory droplets. Larger droplets quickly fall to the ground, while smaller droplets mix in the air, thus forming aerosols. They can remain suspended for many hours due to the effect of air drag in relation to gravity.
Scientists have analyzed the relationship between solar radiation and the amount of ultraviolet radiation that reaches the planet Earth with the elimination of the coronavirus. According to the study’s findings, only one ten-thousandth of Covid-19 survives outdoors throughout the year. Meanwhile, in Reykjavik, the capital of Iceland, this great influence only occurs in the months of June and July, in summer.
Alois Schmalwieser adds that solar disinfection has been shown to be highly effective in aerosols. About whether or not the coronavirus is sensitive to heat, he explains that they would be necessary 60 degree to eliminate it, and this temperature is only reached in the desert.
Right now, Modern and Pfizer They are leading the race to develop an effective coronavirus vaccine. Moderna plans to produce up to 1 billion doses by the end of 2021, while Pfizer has launched a program to distribute its vaccine in several states in the United States.
This week, Juan Andrés, director of Technical Operations and Quality of the Modern Pharmaceutical, has granted an interview to ‘Antena 3’ to talk about the distribution of the vaccine in our country. He explained that right now the company is pending to sign a contract with the EU. The next step will be to receive approval from the European Medicines Agency, and from this point, distribution can begin. The director believes that by early 2021 the supply chain in Europe.
