Foot-and-mouth disease has stricken two more provinces of Vietnam, raising the number of its affected localities to 30, according to a local animal health agency on Wednesday.
Foot-and-mouth outbreaks occurred in a district of northern Hai Duong province with 17 infected bulls, and in three districts of northern Lai Chau province with 125 infected bulls and buffaloes several days ago, said the Department of Animal Health under the Ministry of Agriculture and Rural Development.
On Tuesday, central Quang Ngai province declared outbreaks of foot-and-mouth disease in two districts of Son Tinh and Binh Son. Over 740 cattle in 11 communes in Son Tinh have contracted the disease, while respective figures in Binh Son are 800 and 10.
The department has sent 27 samples from infected animals abroad for testing, whose results will come out in the next 4-6 weeks. Recent studies showed that foot-and-mouth viruses could dramatically change, so surveys for choosing suitable vaccines should be conducted every two or three years, said local media.
Vietnam is intensifying control over cattle transport and trade in affected areas, surveillance of the disease and vaccination of healthy animals.
Foot-and mouth disease has jumped to 242 communes in 30 cities and provinces nationwide, hitting nearly 27,000 pigs, bulls and buffaloes, of which over 10,600 have been killed or culled by the disease, said the department.
