Mizoram is heaving a sigh of relief. The state animal husbandry and veterinary department today said the outbreak of Porcine Reproductive and Respiratory Syndrome (PRRS) in the state is considered to have been temporarily contained. Since August 19, the state hasn’t seen a swine death and this points out to the fact that the disease has been contained, though a possibility of a recurrence isn’t ruled out.
What is PRRS?
PRRS (Porcine Reproductive and Respiratory Syndrome) disease causes reproductive failure in breeding stock and respiratory tract illness in young pigs. It is also referred to as “mystery swine disease” and “mystery reproductive syndrome”. Also known as blue ear disease, the disease syndrome had been first recognised in the USA in the mid 1980’s. The virus responsible is known as PRRSV.
Secretary to the department K Lalnghinglova said, there are no report of swine death, though recurrence of the endemic situation is not ruled out, and the department considered that PRRS outbreak, reported from early April this year, has been temporarily contained.
‘Unless all the suspected carriers of the dreaded PRRS virus are culled and the excretions sterilised, there is a high possibility of recurrence of the outbreak even after a few years’, he said.
Repurcussions and Eventual Control
At least 3,727 pigs and piglets died in the latest PRRS outbreak, in six districts which spared only Kolasib district bordering Assam and Mamit district on the border of Tripura. Worst hit among them was Champai district bordering Myanmar recording 2,523 deaths, the department said.
The outbreak prompted the state government to ban import of pigs and piglets, especially from Myanmar, where the dreaded swine disease is reported to be prevalent almost all the time.
