The new enemy of humanity- Corona Virus is spreading rapidly accross the world afecting 177 Country claiming 30,433 Deaths and 486,063 currently infected patients (updated till 29th march 2020-2.25 AM).
The reason to worry is the ripple effect of the COVID-19 outbreak which could potentially bring major challenges to worldwide health systems
and have far-reaching consequences on the global economy if the spread of the virus is not effectively controlled.

Background
New coronavirus 2019-nCoV is now officially
designated as severe acute respiratory syndrome-related corona virus SARS-CoV-2, represents a pandemic threat to global public
health. The epicenter of the COVID-19 outbreak in December of 2019 was located in Wuhan, China.
What is it CoVs?
Coronaviruses (CoVs) are relatively large viruses containing a single-stranded positive-sense RNA genome encapsulated within a membrane envelope. The viral membrane is studded with glycoprotein spikes that give coronaviruses their crown like appearance. While coronaviruses infect both humans and animals, certain types of animals such as bats that host the largest variety of coronaviruses appear to be immune to coronavirus-induced illness.
There are four classes of corona viruses designated as alpha, beta, gamma, and delta.
The beta coronavirus class includes severe acute respiratory syndrome (SARS) virus (SARS-CoV), Middle East respiratory syndrome (MERS) virus (MERS-CoV), and the COVID-19 causative
agent SARS-CoV-2. Similar to SARS-CoV and MERS-CoV, SARS-CoV-2 attacks the lower respiratory system to cause viral pneumonia, but it may also affect the gastrointestinal system,
heart, kidney, liver, and central nervous system leading to multiple organ failure. Current information indicates that SARS CoV-2 is more transmissible/contagious than SARS-CoV.8.
