Presence of parasite on the surface of the body of host is called as :

  • A.Infestation
  • B.Infection
  • C.Pollution
  • D.Contamination

Answer: A

Parasites living on the body surface of the host constitute an Infestation.

The term is used for ectoparasites such as lice, ticks, mites and fleas, which live on the skin or hair rather than inside the body. Infection is the corresponding term for the entry and multiplication of a parasite or microbe inside the host's tissues, for example a bacterial or protozoan infection.

Pollution refers to harmful substances in the environment, and contamination to the presence of an agent on objects or in food, water or wounds; neither describes a parasite living on a host.
