Question

"Pranay suffered from measels at the age of 10 years. There are rare chances of his getting infected with the same disease for the rest of his life". Give reasons for the statement.

Answer 1

Measles is a disease which generally occurs in childhood and usually results in lifelong immunity. When somebody suffers from measles antibodies of this disease is produced inside his body and are stored. In future whenever the virus of this particular disease attacks the person’s body, the antibodies which are stored recognize the virus easily and start action to kill the virus. Thus if the infection is not extremely severe, the disease can be prevented by self immune system.
