The lockdown will last until a further announcement from the Ministry of Health. The township, covering nearly 27,500 ha, is home to 1,629 households with 7,623 people.

Ha Giang recorded its first COVID-19 infection case on April 16 - a H’Mong ethnic minority girl in Dong Van district’s Pho La commune.

The source of her infection is yet to be determined. She has three brothers who all work across the border in China but none have tested positive for the SARS-CoV-2 that causes the disease.

Health authorities have to date taken test samples from 358 people that had contact with the patient. Of these, 302 samples were negative, with the remainder still waiting for results./.
