More information about fleas


Physiology and Structure:

They are small, wingless insects with laterally compressed bodies, long legs that are adapted for jumping and mouthparts to suck blood from the host.


Clinical Syndromes:

  • The irriatation caused by the flea saliva may produce physical findings that vary from small, red welts to diffuse, red rash.
  • Some flea bites may be painful and pruritic.
  • Infected tissues can lead to severe inflammation and ulcerated.
  • In extreme cases, amputation is needed.



Flea infestation is inferred in a patient with disturbing bites who is also a pet owner. Both the patient and the pet usually undergo examination which reveals the characteristic insect.


Treatment, Prevention and Control:

  • Insecticides can help to control fleas at the source.
  • Repellents can also protect people against fleabites.
  • Flea collars or powder are also one of the effective preventive measures.
