More than 1,300 pigs have died across five districts of eastern Assam of classical swine fever at a time when pig farmers have been hit by the lockdown to curb the spread of COVID-19.  

Classical swine fever  

  • Classical swine fever (CSF) or hog cholera (also sometimes called pig plague based on the German wordSchweinepest) is a highly contagious disease of swine(Old World and New world pigs).It is mentioned as a potential bioweapon.   
  • Lactating piglets show these symptoms like vomiting, diarrhea, lack of coordination, conjunctivitis, high fever, sudden death, malformations, congenital tremor(when piglets are very weak at birth)  
  • The virus is transmitted from infected or carrier pigs through nasal and mouth discharges, urine and feces. It is very contagious.  
  • It can enter a herd through contaminated meat (can be transmitted through uncooked pork meat or cured meat).  
  • Mechanical transmission is common through boots, clothing, trucks, etc.  
  • Co-infection with PRRS virus.  
  • Vaccination is effective in enzootic areas and in high risk areas may be mandatory.  
  • Most countries free of the disease do not include vaccination in their national eradication programs of the CSF, and is usually prohibited.  
  • In areas where the CSF's virus is endemic it is normal to vaccinate all pigs at two weeks of age. Piglets born from vaccinated sows would be vaccinated at the age of 8 weeks. This policy generally results in the elimination of the virus from that region.
