Explained: What is African Swine Fever reported in India for the first time?

News:In Assam, over 2,900 pigs have died due to African Swine Fever (ASF). This is the first time that an ASF outbreak has been reported in India.


  • African Swine Fever: It is a highly contagious and fatal animal disease that infects and leads to an acute form of hemorrhagic fever in domestic and wild pigs.
  • Causes: It is caused by a large DNA virus of the Asfarviridae family.
  • Transmission: It is transmitted to pigs through: 
    • direct contact with infected domestic or wild swines
    • indirect contact through ingestion of contaminated substances or
    • contaminated material such as food waste, feed or garbage or through biological vectors such as ticks.
  • Human Transmission:It is not a threat to human beings since it only spreads from animals to other animals.
  • Mortality Rate:It is close to 100% and since the fever has no cure, the only way to stop it spreading is by culling the animals.
  • Difference: ASF is differentiated from Classical Swine Fever(CSF), whose signs may be similar to ASF but is caused by a different virus for which a vaccine exists.
  • The disease is listed in the World Organisation for Animal Health (OIE) Terrestrial Animal Health Code and thus reported to the OIE.
