So far, the five provinces of Dak Nong, Quang Nam, Quang Tri, Quang Binh and Ha Tinh have not passed the 21-day deadline to declare themselves freed of the disease.

Also in the same period, the blue-ear pig disease has broken out in Dak Lak, Vung Tau, and Bac Lieu provinces.

The Deputy Minister of Agriculture and Rural Development Diep Kinh Tan has asked the infected localities to take drastic measures to prevent the spread of the epidemics. He has urged provinces, especially those in the central region to control the transport of livestock products through border gates.
