Coronavirus did not escape from biological warfare laboratories and was not prepared by Biotechnology Research Laboratories or by a bioterrorism-related Laboratory, according to SCRIPPS RESEARCH INSTITUTE of the USA one of the top five research centers in the world.
A big question for the Coronavirus is whether summer with sunshine and warmer weather - as with flu, for example will help in dealing with the situation. The answer is optimistic. Many experts have questioned this optimistic scenario, which is also being researched at the University of Utah, will be implemented to help understand the response of the virus as times of the year change.
Since antiquity, millions of people have died from epidemics, viruses and deadly diseases. We made a retrospective and collected the most important diseases that shocked history and killed millions of people around the world.
According to a study published in March 17 in the New England Journal of Medicine by NIAID researchers ( The National Institute of Allergy and Infectious Diseases), (part of the US National Institutes of Health) can withstand three to four days on a surface, depending on material and environmental conditions, which means it can be transmitted to whoever touches them every now and then puts his hand on his face. This also shows how important is to thoroughly clean using disinfectants everything we bring home from supermarkets, bakeries, etc. In particular, the above research shows that SARS-CoV-2 virus survives up to four hours on a copper surface, up to one day on cardboard and up to three days on plastic and stainless steel. In the air it can survive for up to three hours, depending on temperature and humidity. The new Coronavirus especially loves stainless steel and polypropylene, a widely used plastic material in plastic packaging.in toys and cars.
The Peloponnesian War (431-404 BC), where Athens was rivaled by Sparta, with each city having its allies, was a landmark in world history. It was such a significant milestone that even this war Thucydides, the historian who wrote the story of the war, considered it as a great lesson for future generations.
During the second year of the war, Athens, where Pericles's personality was dominant, occurred a catastrophic pandemic outbreak, probably by a boat that reached the port of Piraeus. The disease was impossible to be cured by the doctors of the time and within a few months claimed the lives of about 25-30% of the inhabitants of Athens, including Pericles himself and his two sons.
The European Food Safety Authority (EFSA) has announced that scientific data on previous outbreaks of similar coronaviruses such as SARS-CoV and MERS-CoV show that no coronavirus was transmitted through food consumption either domestically produced or imported from abroad. To date, there is no evidence that the new Coronavirus is different from the two previous ones in terms of its transmission.
The European Center for Disease Control states that the Coronavirus is transmitted through the respiratory tract by droplets from infected people coughing or sneezing or releasing droplets in any way. Coronavirus enters the respiratory system and particularly in the bronchi and the lungs thus multiplying and finally causing the well knows symptoms such as coughing, fever etc.
Humanity over the centuries has been tested by many infectious diseases resulting in significant human losses due to people's ignorance about the nature of diseases, hygiene rules and ways of transmitting them. Even in antiquity, as in the Plague of Athens (430 BC) during the 2nd year of the Peloponnesian War, people were not able to stop with the transmission of the disease, which was achived by the great physician Hippocrates using the scientific methods available in his time. That is, the observation of diseases and the knowledge of human physiology.
The need for control is one of our most fundamental human needs. In times such as these, the world is a lot less controllable and predictable that we would like. We are being told to self-isolate or quarantine, for an unknown length of time. Whilst this advice is extremely important and it is essential we follow it in order to contain the virus, this type of advice can also make us feel helpless, negative and uncertain about the future.
We tend to worry more about new risks than familiar ones. The vast majority of us are concerned, and some are beginning now to experience symptoms of stress. So what can we do to get back our sense of control and order, and maximise our physical and mental health?
