Have you ever been down with a kind of cough that takes your whole breath away, and just within a few seconds, you catch a glimpse of death? Coughs can leave you with a completely dry and scratchy throat, making you crave water now and then like a jellyfish. This scary and chronic cough is called a Whooping Cough. 
Whooping cough is a disease of the respiratory mucous membrane, and it is otherwise known as Pertussis. It is a bacterial infection caused by a bacteria called Bordetella pertussis. It is also contagious and is transmitted through airborne respiratory droplets (coughs and sneezes), saliva, and close contact with an infected person.
