The word around us these days is not as it used to be, most of the businesses are inactive and public transportation is limited. These are just two of the many results caused by the pandemic of Covid-19, a virus which was initially identified in December 2019 in Wuhan. After the outbreak of this new virus, the entire scientific community is in a constant search for both its origin and possible treatments.
Coronavirus is not actually a new virus like everybody thinks. It was discovered in the 1930s when an intense respiratory disease of tamed chickens were OK so demonstrated to be brought about by an bronchitis infection (IBV). In the 1940s, two more animals coronaviruses, mouse hepatitis virus or else MHV and transmissible gastroenteritis virus which is also as TGEV. Those two animals were isolated. Then, in the 1960s coronaviruses were discoverd in humans. The earliest studies were from people with normal cold, which were later named as human coronavirus. But what is coronavirus? Coronavirus is a group of connected viruses that cause diseases in mammals and birds. This virus can appear as a common flu or a very severe respiratory sydrome (SARS). In 2019, a new coronavirus was identified as the cause of a disease outbreak in China that originated in China (Mayo Clinic, 2020). This new kind of virus is called COVID-19.
Severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) or Coronavirus infectious disease (COVID-19) is an infectious disease of primarily the human respiratory tract caused by the novel corona virus. The virus is believed to be of zoonotic origin and it can easily be transmissible between humans via airborne droplets. Through mathematical models the virus yields a basic reproduction number (R0) of approximately 2 to 2.5 . The incubation time of the virus is between 1 and 14 days, the hospitalization rate is 19% and the fatality rate is 1% to 3.4%. More recent studies conclude that the true R0 value is closer to 7 .
Coronavirus is a type of virus. There are many different kinds, and some of them cause disease. A newly identified type has caused a recent outbreak of respiratory illness it’s like the common cold to more severe diseases such as severe respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) now is called COVID-19.
Coronavirus is the name for a large group of illnesses, including the common cold and other respiratory infections. The 2019 novel (the term “novel” means it’s a new form of the virus) coronavirus has been named SARS-CoV-2 and causes a disease called coronavirus disease 2019, or COVID-19. The origin of the virus is still not clear, but we learned about this virus after a cluster of severe pneumonia cases were reported on New Year’s Eve 2019 in the city of Wuhan, China.
Four months ago, in China specially in Wuhan a new virus was born. Some people say that the virus came from an infected bat, and some people support the other theory which was a laboratory mistake which was done by the workers. At the first story we have an infected, bat which was ate by someone in Wuhan and then all started. This human was ignoring the symptoms and continued his life like none of that ever happened, until one day that he went to the hospital and the virus was already developed in his body and affect a lot of people in his way before everyone could notice. At the end this virus was ended up affecting the most, of the people in China.
Coronaviruses are a family of viruses which can cause acute respiratory problems like Middle East Respiratory Syndrome (MERS) or Severe Acute Respiratory Syndrome (SARS) and they were primitively spread from animals to humans. The name of this virus originates from the Latin word “corona” which means crown, beneath the electronic microscope the coronavirus looks like it is encircled by a solar corona. The newly observed novel of coronavirus is called COVID-19, it was first discovered in December of 2019 in China and had not been found in humans till then (Aljazeera 2020) (World Health Organization 2020). When a person ate a bat, the current strain was transmitted to the individual and caused respiratory problems which led to its death. The disease was rapidly appeared have a structural similarity to the virus that caused the SARS. As in two previous examples of development of coronavirus disorder in the past eighteen years – SARS and MERS – COVID-19 outbreak has provoked critical challenges for the national healthcare systems, research programs and medical associations (Fauci et al. 2020).
It is true the fact that, since the previous year there was a new treat for humankind that is called coronavirus. According to the World Health Organization (WHO), coronaviruses are a family of viruses that can cause diseases from the common cold to more severe occasions such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).
