Facts About coronavirus: You must know

Friends Coronavirus, which came into the discussion in 2020 when its first case was first found in China Wuhan.And according to WHO data so far 113,000 people are infected and about 4,000 people have died,

So today I will tell you about some facts related to coronavirus which you need to know,


Friends, do you know that there are many types of Coronavirus,There are 4 main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta.Of the coronavirus discovered so far, Three Coronavirus commonly infect humans,

1.229E (alpha coronavirus)
2.NL63 (alpha coronavirus)
3.HKU1 (beta coronavirus)

People around the world commonly get infected with human coronaviruses 229E, NL63, OC43, and HKU1.

Sometimes coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. Three recent examples of this are 2019-nCoV, SARS-CoV, and MERS-CoV.

1.MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)

2.SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)

3.SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)


Coronaviruses are named for the crown-like spikes on their surface ,And Human coronaviruses were first identified in the mid-1960s. 

The most publicized type of coronavirus is the virus that causes Severe Acute Respiratory Syndrome or SARS. The virus that causes SARS is known as SARS-CoV. This virus first appeared in Southern China in November of 2002 and was recognized as a global threat in March of 2003.

During that time, SARS spread worldwide infecting at least 8,098 people and killing 774 people, according to the World Health Organization (WHO). 

By late July 2003, no new cases had been reported and WHO declared the global outbreak to be over.

And now recently COVID-19 most publicized type of coronavirus Which is known as the next version of SARS-CoV(SARS-CoV 2).


Researchers currently think that between five and 40 coronavirus cases in 1,000 will result in death, with a best guess of nine in 1,000 or about 1%.
the World Health Organization's Director General, Tedros Adhanom Ghebreyesus, said that "globally, about 3.4% of reported Covid-19 cases have died".
Scientists' estimate of the death rate is lower because not all cases are reported.
On Sunday, Health Secretary Matt Hancock said the UK government's "very best assessment" was that the mortality rate was "2% or, likely, lower".
But it depends on a range of factors: your age, sex and general health and the health system you are in.

The death rates were lowest for the under 30s - there were eight deaths in 4,500 cases.
And deaths were at least five times more common among people with diabetes, high blood pressure or heart or breathing problems.
There was even a slightly higher number of deaths among men compared to women.

All of these factors interact with each other and we don't yet have a complete picture of the risk for every type of person in every location.
