Secondly, the districts had bird flu outbreaks or cases of bird flu reported at least twice in the last five years (2014-18) or within two years after they are removed from the low-risk district list. Now, there are six disease-free poultry production zones in Việt Nam and 654 poultry farms are certificated disease-free. Deputy Minister of Agriculture and Rural Development Phùng Đức Tiến said monitoring the bird flu virus circulation effectively helped prevent and control bird flu. Between 2014 to March, 2019, about 90,000 poultry were killed because of bird flu each year. Since April, 2014, no one in Việt Nam has been infected with bird flu.
