In the face of the epidemic’s complicated developments, thousands ofhealth workers have been dispatched to all communes and towns across theprovince to help put the deadly flu strain under control.
Sharing those efforts, the neighbouring province of Yen Bai ,which reported two deaths by A/H1N1, has taken a range of preventivemeasures against the flu, focusing on raising public awareness ofthe epidemic.
Over the past month, the province hasconducted testing on 118 cases, of which 28 were found positive forA/H1N1, raising the locality’s total flu infections to over 5,200 so farthis year.
The first A/H1N1 outbreak hit Nguyen Thai Hoc ward, Yen Bai city in mid-April, bringing four people to hospital.
Meanwhile, the People’s Committee of southern Dong Nai province hasrequired relevant agencies to promptly implement measures againstpossible flu outbreaks.
The province will spend part of its budge purchasing Cloramin B, protective clothes and Taminflu to deal with the epidemic.
The provincial health sector has opened H7N9 prevention trainingcourses for about 200 health workers and carried out preventive plansfor the new strain of avian influenza.
Tran VanQuang, head of the provincial Veterinary Department, said all 74 samplesof swallows (salanganes) collected from the province’s localities havebeen tested negative for the avian flu virus.
