African swine fever:


Context:

Small farms in Asia are the worst hit by the African Swine Fever outbreak. Why?

  1. Pig farms remain dominantly an affair of small-scale farmers.
  2. In many countries, including India, 70 per cent of the pig farms are owned by small-scale farmers.
  3. In China, almost 98 per cent of the total pork production is by small-scale farmers who have fewer than 100 pigs each.

 

Impact in India:

  • African swine fever, a century-old disease that infects pigs and wild boars with a near 100 per cent fatality rate, has claimed a third of the world’s pigs since 2018.
  • Its latest victim is India, where cases have been reported since May 2020 but have exploded in the past couple of months.
  • Estimates show that ASF has caused a 50 per cent shortage in northeastern states’ pork production.

 

About African Swine Fever (ASF):

  • ASF is a highly contagious and fatal animal disease that infects domestic and wild pigs, typically resulting in an acute form of hemorrhagic fever.
  • It was first detected in Africa in the 1920s.
  • The mortality is close to 100 per cent, and since the fever has no cure, the only way to stop it spreading is by culling the animals.
  • As of now, there is no approved vaccine, which is also a reason why animals are culled to prevent the spread of infection.
