Lumpy Skin Disease:

What is it?

  • Lumpy Skin Disease is a viral illness that causes prolonged morbidity in cattle and buffaloes.
  • Caused by the poxvirus Lumpy skin disease virus (LSDV).


  • It appears as nodules of two to five centimetre diameter all over the body, particularly around the head, neck, limbs, udder (mammary gland of female cattle) and genitals. The lumps gradually open up like large and deep wounds.


  • It spreads through mosquitoes, flies and ticks and also through saliva and contaminated water and food.

Affected Countries:

  • LSD is endemic to Africa and parts of West Asia, where it was first discovered in 1929.
  • In Southeast Asia the first case of LSD was reported in Bangladesh in July 2019.
  • In India it was first reported from Mayurbhanj, Odisha in August 2019.


There is no treatment for the virus, so prevention by vaccination is the most effective means of control.


  • The Bihar government sounded an alert and issued an advisory about the likely spread of the disease.


  • In India, which has the world’s highest 303 million heads of cattle, the disease has spread to 15 states within just 16 months.
  • This might have a devastating impact on the country, where most dairy farmers are either landless or marginal landholders and milk is among the cheapest protein sources.
