The Lumpy Skin Disease

The Lumpy Skin Disease

Origin:

  • The Lumpy Skin Disease was initially found in an outbreak in Zambia in 1929.
  • The Lumpy Skin Disease is caused by the LSD virus (LSDV), a poxvirus of the genus capripoxvirus.
  • The studies indicate that until the 1980’s the virus was widely confined to African Continent until it was found in Israel in 1989.
  • And in the recent years Lumpy Skin Disease is being reported all over the world especially China, India, Nepal, Bhutan, Vietnam, Hong Kong and Myanmar.

Status in India:

  • Suspected cases of LSD were observed in Odisha in August 2019, the first laboratory-confirmed outbreak of LSD was subsequently reported in November 2019.
  • Sequences of particular genes of the isolated virus from the 2019 outbreak were genetically similar to strains from Kenya.
  • Large outbreak of LSD was reported from Gujarat and Rajasthan in July 2022, which subsequently spread to 11 other States with over 80,000 cattle deaths.
Mutations:
  • Department of Animal Husbandry in Rajasthan in association with CSIR Institute of Genomics and Integrative Biology(CSIR – IGIB) has reported the whole genome sequences of six isolates of LSDV collected from five affected animals.
  • From the report it could be inferred that there were almost 177 unique mutations when compared to those that was found in Kenya.
  • It is interesting to know that out of these 177 mutations, 47 were found to be not present in any other global genome sequences of LSDV.
Way Forward:
  • As the world is gearing up towards a holistic concept of ‘One Health’, viruses like this may disrupt the entire ecosystem.
  • As the recent experience from the Covid-19 pandemic clearly highlights the urgent need of adopting towards One Health.
  • Food security is a key factor in nurturing the human resource, so agriculture plays a huge role in the world from which the cattle cannot be separated.
  • With newer and better tools like molecular surveillance and digital technologies to identify and stop emerging pathogens, the world must gear up towards it.
