Coronavirus COVID-19

Coronavirus has glycoprotein spikes that project from their surface and look like corona from which their name derives. Coronavirus is not a newly discovered virus. Coronaviruses are a large group of related viruses which might cause illness in mammals like humans and birds. In humans, coronaviruses cause respiratory tract infections that can be mild such as a common cold or more severe diseases like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19. The COVID-19 outbreak began in Wuhan, China, in December 2019 and ever since this virus is spread all over the world with 1.503.900 confirmed cases and 89.931 total deaths. That is the reason why World Health Organization calls it a pandemic. The origin of COVID-19 is unknown but there is a theory that it was caused by bats. This coronavirus does not have an age limit.

CORONAVIRUS: The most talk about topic of 2020

Coronavirus SARS-COV2

Lately, words like "virus" and especially "coronavirus" have entered our daily lives. But what exactly is a virus? It is a pathogen that infects the cells of an organism by incorporating its genome into the genetic material of its host. Through the control of cellular mechanisms, the virus multiplies, thus creating problems in the body.

Coronavirus and conspiracy theories

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.

Summer and Coronavirus

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.

History of epidemics

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.

Coronavirus and infected surfaces

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.

Short history lessons: Epidemics in antiquity, the plague of Athens

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.
