Aizawl: At least 3,168 pigs and piglets have died in Mizoram due to the outbreak of Porcine Reproductive and Respiratory Syndrome (PRRS) and Classical Swine Fever (CSF) since March this year.

State Animal Husbandry and Veterinary deputy director Dr. K. Lalrohlua (Disease Investigation) said that the figure was collected from all the eight districts of the state where the outbreak had spread.

As per the record available with the department  till 28 July, 3,168 pigs and piglets have died due to PRRS and CSF and majority of them were piglets, he said.

He said that about 7,138 pigs and piglets have taken ill till date due to the outbreak of PRRS and CSF.

According to Lalrohlua, the first PRRS case was identified from Zokhawthar village on Mizoram-Myanmar border on 17 March and that of CSF was detected on April 13.

He said that the two swine diseases have gripped the entire state and at least 105 villages in all the eight districts were affected.

Of the 620 blood sample tested during March to July, 349 pigs were found infected with PRRS, while 277 others tested positive for CSF, he added.

Although the outbreak is not fully controlled, it has been waned, he said.

According to Lalrohlua, Aizawl district was the hardest hit with 1,923 pig deaths, followed by Serchhip district with 456 deaths.

363 pigs and piglets died in southern most Lawngtlai district, 174 in Champhai district, 158 in Siaha district, 71 in Kolasib district, 12 in Lunglei district and 11 in Mamit district.

According to the deputy director, the state government is taking massive effort to curb the outbreak.

He said that the government has banned import of pigs from neihbouring states and countries and also prohibited inter-village movement of pigs.

All pig farmers were also instructed to cull their ailing pigs and also buried dead pigs in deep underground, he added.

Lalrohlua also said that the PRRS outbreak was somehow prevented in some district due to administration of CSF vaccine although there is no appropriate vaccine for PRRS.

He said that the first phase of mass CSF vaccination will be launched in all parts of the state from August to October to prevent further outbreak.

 The PRRS also hit Mizoram in 2013 and 2016. More than 3,000 pigs and piglets were died in 2013 and over 4,000 pigs were culled due to the outbreak of PRRS in 2016.
