What is Coronavirus and COVID-19?
2020 has enriched our vocabulary with many new words: Coronavirus, COVID-19, vaccine, Wuhan, antibodies, and more. Combined with social distancing and constant fear of infection, this information flow gets us overwhelmed. Although we just want to know how dangerous the situation is and when it all will be over, and we shall be able to return to our healthy lifestyle. Let`s try to connect the dots and see the full picture.
Although Coronavirus became a mega-star in 2020, it is not that new and unique as you think. Medicine knew lots of types of coronaviruses before. Most of them were spread among animals only and familiar to the veterinary.
Therefore, they were invisible by common medicine. The main qualities of viruses are their microscopic size and enormous contagiousness. They also constantly mutate. It was only a question of time when Coronavirus will be able to spread among people.
Difference between “Coronavirus” and “COVID-19:
That is why it is essential to mark the difference between “Coronavirus” and “COVID-19”. Although they are mostly used as synonyms. These are two different concepts.
COVID-19 – is a disease caused by one particular type of Coronavirus. It has managed to adapt to the human body enough to become highly contagious between people. Its full name was CoronaVirus Disease in 2019. Although it became viral in 2020, it was first identified in December 2019 in Wuhan, China. This explains the origin of “19” in its name.
COVID-19 is an intensely infectious disease caused by a strain of Coronavirus. One of the main aspects of this disease is that its symptoms are very similar to regular cold or flu. Which is what helped it spread all over the world. Fever, caught, fatigue, shortness of smell – all of us experience these symptoms from time to time. That is why it was not taken seriously. And treated accordingly in the very beginning of the epidemic.
Moreover, it is quite common that an infected person does not have any symptoms at all. He may not even suspect that he is carrying a highly contagious and potentially dangerous disease. In this case, you may say that Coronavirus behaves like a parasite, using the infected person for transportation and spreading.
Complications of COVID-19:
Complications of COVID-19 mostly affect the lungs and appear as pneumonia and ARDS (a widespread inflammation of the lungs). This means that the risk of contamination is equal for everybody. Your age, health condition, place of living, and social status does not matter. But the course of the disease is different for everyone. The severity of the disease depends not only on the immune system.
The condition of the lungs and possible concomitant chronic diseases is very important. This explains that the fatality of Coronavirus is minor for young children. It rises with the age range. Babies, toddlers, and young children are very unlikely to have lungs damaged by air pollution, smoking, and other complicating factors.
WHO (World Health Organisation):
Still, there are many arguments about the fatality of COVID-19. It happens because the WHO (World Health Organisation) still did not work out a standard international method of statistical calculation of mortality rate of COVID-19. Some countries mark COVID-19 as a cause of death to every person who has died during this period. If he had Coronavirus in his blood, it means that he has died because of it.
Is COVID-19 an accompanying disease?
Others prefer to mark COVID-19 as an accompanying disease. The idea is that it has a complicated patient`s common poor physical condition. But in this case, COVID-19 was not the actual cause of death. This statistical disorganization and political ambitions of some governments lead to the fact that we still don`t know the real mortality rate of the disease.
