Last January, some hotbeds of A/H5N1 in poultry were reported in the Cambodian province of Svay Rieng, which also borders Vietnam, according to the World Organisation for Animal Health.
There is a high risk that these bird flu viruses will enter Vietnam, Phu said.
Deputy Minister of Health Nguyen Thanh Long said avian influenza viruses, especially A/H7N9, are likely to enter Vietnam if effective preventive measures are not taken.
Meanwhile, the Ministry of Industry and Trade, the Ministry of Public Security and the border guard force need to prevent fowl smuggling and deal with illegal poultry business activities strictly.
Long also requested the National Institute of Hygiene and Epidemiology and Pasteur institutes in the central and southern regions to focus on suspected cases in localities bordering countries with bird flu outbreaks.
In 2016, Vietnam recorded A/H5N1 outbreaks in poultry in seven communes and wards of six districts and townships in Nghe An province, Ca Mau province and Can Tho city. There haven’t been any A/H5N1 outbreaks in 2017, according to the Preventive Medicine Department.
The flu viruses of A/H7N9, A/H5N8 and A/H5N1 have yet to be reported in humans in Vietnam. The A/H3N2 and A/H1N1 viruses and type B viruses are seasonal influenza viruses in the country.
