Corona virus: What are the symptoms, treatment and prevention of Covid-19 disease, how severe it is, how widespread and fast it is spreading in which country

Coronavirus, also known as Covid-19, has spread to 16 countries around the world.

The virus, which causes serious lung disease in humans - previously unknown to scientists - has spread from China.

What is the virus?

Coronavirus is a contagious virus that has never spread to humans before.

The number of deaths worldwide from this virus is on the verge of one million. And the number of global identities is on the verge of three million. (Data updated 14 September 2020)

Another name for the virus is 2019 - NCOV or Novel Coronavirus. It is a type of coronavirus. There are many species of coronavirus, but only six species can be transmitted to humans. However, due to the new type of virus, that number will be seven from now on.

The SARS (full name Severe Acute Respiratory Syndrome) virus, which has been spreading in China since 2002, has killed 64 people and infected 6,096 around the world. That too was a kind of coronavirus.

The new disease was initially called by various names, such as: 'China virus', 'Coronavirus', '2019 Encav', 'New virus', 'Mystery virus' etc.

In the second week of February this year, the World Health Organization officially named the disease Covid-19, which is an acronym for Coronavirus Disease 2019.

Coronavirus disease renamed 'Covid-19'

What are the symptoms of the disease:

In addition to respiratory symptoms, fever, cough, and respiratory problems are the main symptoms.

It attacks the lungs.

Symptoms usually begin with a dry cough and fever, followed by respiratory problems.

It usually takes an average of five days for the symptoms to appear.

The World Health Organization says the incubation period of the virus lasts up to 14 days. However, according to some researchers, it can last up to 24 days.

When people show symptoms of the virus, more people are more likely to be infected. However, the idea is that people can infect healthy people even when they are not sick.

Since the early symptoms are similar to those of the common cold and flu, it is normal to be hesitant to diagnose.

The outbreak of the coronavirus reminds many of the SARS virus, which in early 2000 killed 74 people, mainly in many Asian countries.

Analysis of the genetic code of the new virus has shown that it is very similar to the SARS virus.

"When we see a new coronavirus, we want to know how severe the symptoms are. The virus is a lot like the flu but not as deadly as the SARS virus," said Mark Ulhaus, a professor at the University of Edinburgh.
