Ephemeral Fever (Three day sickness)

  • Ephemeral fever is viral disease of cattle and buffalo.
  • It is an insect-transmitted disease.
  • Persists usually for 3 days.
  • Morbidity may be very high but mortality is very low (1-2%).



  • Biphasic to polyphasic fever with shivering, tears from eyes and decreased appetite.
  • Nasal discharge, drooling, labored breathing, depression, stiffness, lameness and sudden decrease in milk yield.



  • Spontaneous recovery usually occurs within a few days.
  • Proper fly control would help to reduce the disease (See chapter on fly management).
  • Complete rest is the most effective treatment. Recovered animals should not be stressed or worked for some days since relapse may occur.
  • Consult a veterinarian for symptomatic treatment.
