All Recent Corona Virus

Coronaviruses are a group or Fmily of viruses which has been identified and containing strains that cause serious deadly diseases in mammals and birds. In humans it is typically spread via air or droplets of internal fluid produced by infected persons.

Some odd but dangerous strains, which also including Wuhan coronavirus (2019-nCoV), and wich those responsible for severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), can cause death in humans.

The Corona virus first described in detail in the 1960s, the coronavirus gets its name from a distinctive corona of sugary-proteins that projects from the envelope surrounding the particle. Corona has the longest genome of any RNA-based virus – a single strand of nucleic acid roughly between 26,000 to 32,000 bases long. 

There are tottally four known genuses in the family, named Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus. Though the first two only infect mammals, including bats, pigs, cats, and humans. Gammacoronavirus mostly infects birds such as poultry, while Deltacoronavirus can infect both birds and mammals.

The Symptoms of Corona Virus

Coronaviruses make someone rise to a variety of symptoms.and also it varies animals to animals, While some strains cause diarrhoea in pigs and in turkeys, most of the time infections can be severe cold and causing mild to moderate upper respiratory problems.
There are a handful of lethal exceptions, which have had a devastating impact on livestock and human health around the globe.
COVID-19 (2019-CoV)

Wuhan corona virus was first identified in the Chinnees province Wuhan in 2019.and about a mortatlity rate of 1% but mortatlity rate increasing day by day as it's  new virus.

Initially Snakes were suspected as a potential source for the Epidemic, though some other experts have pointed it is very unlikely and proposed bats instead. As of February 2020, the search for the animal origin of (2019-nCoV) is ongoing.

Severe acute respiratory syndrome (SARS-CoV)

SARS was first found as a a unique strain of coronavirus in 2003. The source of the virus has never been found, though the first human infection is tracked back to the Chinese province of Guangdong in 2002.

The virus then became a global threat, causing more than 8,000 infections like influenza disease in 26 countries with close to 800 deaths.

Middle East respiratory syndrome (MERS-CoV)

MERS was first identified in Saudi Arabia in 2012 in people showing symptoms of fever, cough, shortness of breath and occasionally gastrointestinal problems such as diarrhoea. a zoonotic orgin of the virus never confirmed, though evidence suggest to dromedary camels as a potential reservoir of infection.

The World Health Organisation has identified around 2,500 cases of infection in 27 countries since initial outbreaks, resulting in nearly 860 deaths,which also point (MERS-CoV) much deadlier than the current (2019-nCoV) .
