With the approaching rainy season, health departments in various countries of the world feared an exacerbation of the epidemic, which has so far killed more than a million and 100,000 people around the world, according to a report published by the “Nature Scientific” magazine.
These concerns came from several factors related to the behavior of people during this season, and the characteristics of the virus that will be active more in cold weather conditions.
We are entering difficult months
David Relman, a microbiologist at Stanford University, revealed that the outbreak will peak during the winter, indicating that we are entering difficult months.
Despite the many opinions that had said that Corona is not seasonal, scientists are now sure that its peak will be in the winter, when viruses and respiratory diseases abound, especially in times of low temperatures and cold weather.
Other scientists have also warned that the speed in reaching results related to anti-Corona vaccines may harm its effectiveness against the virus, which is spreading strongly.
Closed places again
Mauricio Centiana, a mathematician at Harvard Medical School, explained that people during the winter, unlike what is common in the summer, will interact more in enclosed spaces, in which the air travels in a closed circuit to preserve heat in buildings and various facilities.
In turn, Rachel Baker, an epidemiologist at Princeton University, said that even if there is a slight seasonal effect of Corona, the presence of a large number of people exposed to infection remains the main driver of the spread of the virus.
Also, an epidemiologist at the London School of Medicine, Kathleen O’Reilly, noted that influenza has existed for hundreds of years, but that the causes of its peak in winter are still not fully scientifically understood, which we find no explanation except for cold weather.
And she indicated that the biggest factor that will limit the spread is only social distancing and wearing masks in indoor and outdoor places.
Although many scientific experiments conducted within the laboratory environment proved that the conditions in winter are greatly favorable for the spread of the virus, especially that the temperature inside homes and various facilities is at an average of 20 degrees Celsius, which means that it is warmer and wetter than the weather outside, but This never proves that Corona is only for winter and negates the rest of the possibilities.
Last April, a report issued by the “National Academies of Sciences, Engineering, and Medicine of America” said that there have been 10 flu epidemics in the past 250 years, two outbreaks in the northern hemisphere winter, three in the spring, two in the summer and three in the fall, and in all cases there were A second wave about 6 months after the virus first appeared, regardless of when the outbreak first occurred.
It is noteworthy that the global news about the virus in the recent period was not at all reassuring, as only a few days passed since the World Health Organization announced to the world difficult and shocking news that the northern hemisphere is facing a decisive moment in the fight against the Covid-19 pandemic, warning that “the months The next few days will be very difficult and some countries are on a dangerous path. ”
The Secretary-General of the United Nations, Antonio Guterres, has confirmed that the Corona pandemic is the largest crisis facing the world in the modern era.
Guterres’ words came when he opened the World Health Summit via the Internet, yesterday evening, Sunday, in which he called for global solidarity in the face of the crisis, calling on developed countries to support health systems in countries suffering from lack of resources.
The Corona pandemic was the main topic of the summit, which was originally scheduled to be held in Berlin.
More than 1 million deaths and 43 million injuries
It is noteworthy that the Covid-19 pandemic has killed more than 1.1 million people since the WHO office in China reported the first outbreak of the disease last December, while the world recorded more than 43 million cases of the virus.
In Europe, the number of registered cases exceeded 8.2 million, of which more than 258,000 people died.
In addition, Tedros Adhanom Ghebreyesus believed that if governments were able to make the systems of searching for contact cases ideal, and focus on quarantining all cases and placing all contacts in isolation, it would be possible to avoid a return to the imposition of comprehensive isolation measures.
