Tran Dac Phu, director of the Preventive Health Department, said HCMC has a high risk of infection due to its large population, which is around 12 million including migrants.

HCMC has the highest number of Zika infections nationwide, and patients from 13 of the city’s 24 districts have all contracted the virus in Vietnam.

Nationally, the Zika tally stands at 44 with the other nine cases being reported from Binh Duong, Dak Lak, Khanh Hoa, Long An, Phu Yen and Tra Vinh provinces.

In late October, a four-month old child from Krong Buk district, Dak Lak province was confirmed at the first Zika-related microcephaly case in Vietnam.
