Four new COVID-19 infections, including two cases related to the HCM City-based Buddha Bar cluster, were reported by the Ministry of Health on Friday afternoon, raising the national toll to 237.
The central province of Quảng Nam had sent 142 local people returning from HCM City to isolation sites in Tiên Phước, Quế Sơn, Thăng Bình and Núi Thành districts as of Friday.
Seven COVID-19 patients in the south central coastal province of Bình Thuận and three in HCM City have recovered and have been discharged from hospital.
The official said the city was also preparing for a worse scenario of 2,000-3,000 patients.
The report showed the country would suffer an ongoing drop in demand from its principal trade and investment partners.
The five imported cases were all quarantined right after immigration so there are no risks of community transmission.
