CORONAVIRUS IS DANGER FOR EVERY ONE.

What Is a CORONAVIRUS?

Coronaviruses are a family of viruses known for containing strains that cause potentially deadly diseases in mammals and birds. In humans they're typically spread via airborne droplets of fluid produced by infected individuals.

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

First described in detail in the 1960s, the coronavirus gets its name from a distinctive corona or CROUN OF SURGURY PROTEINS that projects from the envelope surrounding the particle. Encoding the virus's make-up is the longest genome of any RNA-based virus – a single strand of nucleic acid roughly 26,000 to 32,000 bases long. 

There are four known genuses in the family, named Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus. 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.

               ( Wuhan coronavirus ) was first identified in the Chinese city of Wuhan in 2019. At the time of writing, numbers of infected are still on the rise, with a number of deaths having been reported.

                                               

                     SARS was first recognised as a distinct strain of coronavirus in 2003. The source of the virus has never been clear, though the first human infections can be traced back to the Chinese province of Guangdong in 2002.

The virus then became a pandemic, causing more than 8,000 infections of an influenza-like disease in 26 countries with close to 830 deaths.

      

             THE World Health Organisation has identified around 2,500 cases of infection in 27 countries since initial outbreaks, resulting in nearly 860 deaths.
