Police said the patient "didn't declare her specific travel schedule nor information on those whom she had been in close contact with," inhibiting contact tracing and timely prevention measures.
As a result, three of her family members were also diagnosed with the coronavirus, Vietnam News Agency reported.
She was the third person to be placed under criminal investigation for spreading the virus since Covid-19 broke out in Vietnam in January 2020. The first was a Vietnam Airlines flight attendant who allegedly breached Covid-19 quarantine protocols last December and infected three others and the second a Vinh Long man infected with the coronavirus who had illegally entered the country in January. Earlier, people flouting Covid-19 prevention regulations were let off with mere fines.
Since Jan. 28, when community transmissions returned to the nation after almost two months, Vietnam has recorded 803 cases, with Hai Duong accounting for the majority at 620.
All of Hai Duong is undergoing social distancing for 15 days starting Feb. 16 as per a government directive on Covid-19 prevention.
