  • According to a research published in the journal “Pathogen”, virus jumped to humans from Pangolins. 
  • Also, mutation was the main reason for the virus to target human cells so easily and hence leads to fast spread of the virus.
  • Pangolins are the most trafficked animals in China. 
  • The COVID-19 virus has a spike protein. 
  • These proteins contain Receptor Binding Domain (RBD) that facilitates the entry of the virus. 
  • The RBD binds with the angiotensin-converting enzyme-2 (ACE-2) found in lungs, heart, kidneys and gastrointestinal tract.
  • The researchers say that COVID-19 is a mutated version of SARS virus that created an epidemic in 2002-03.
