After reporting four Zika virus infections in Vinh Thanh Commune since end of December, the steering board of disease prevention in the southern province of Dong Nai last week announced a Zika epidemic.
Officials decided to announce epidemic to warn people of the disease and adopt measures to curb its spreading.
In the Mekong Delta province of Ben Tre, officials have reported the first case of the Zika virus in a 25-year-old woman who is 18 weeks pregnant.
Do Tan Hong, head of the province’s preventive medicine center, said because the patient lives near an industrial park crowded with migrant workers, there is a risk of the virus spreading that has to be monitored carefully.
Vietnam has reported 212 Zika virus cases since the first cases were seen last fall. The outbreak is most prominent in Ho Chi Minh City, which has 186 cases, including 12 pregnant women.
