BÀ RỊA-VŨNG TÀU — A mother and her baby daughter have tested positive for COVID-19 for a second time - after they were given the all-clear and released from quarantine. 

Now the authorities are trying to trace anyone they came into contact with and are spraying disinfectant at areas they had been.

The 37-year-old woman is from Russia and came to Việt Nam with her one-year-old child to be with her husband who is working for the Việt Nam-Russia oil and gas joint venture Vietsovpetro in Vũng Tàu City in the southern province of Bà Riạ-Vũng Tàu.

They were quarantined at a hotel in Cam Lâm District in central Khánh Hòa Province on arrival, and tested positive for the virus on November 26.

The two were taken to a medical centre in the district and recovered on December 25, according to Bà Riạ-Vũng Tàu province’s centre for disease control.

After being given the all-clear, they were quarantined at a hotel in Lộc Thọ Ward, Nha Trang City, Khánh Hòa Province, and completed quarantine on January 7. During the quarantine period, both tested negative for the virus twice.

After learning about the relapse, the Vietsovpetro Medical Centre under the joint venture disinfected the areas where the two had visited, and conducted contact tracing.

They were reported to have travelled by taxi from Nha Trang to Cam Ranh Airport, then boarded flight VN 6203 to HCM City and then by bus to Vũng Tàu on January 8.

Three identified F1 cases who came into close contact with her are her husband and two health workers at the centre. All three are currently at a concentrated quarantine establishment in Bà Riạ-Vũng Tàu. 

The 21 F2 cases who have had secondary contact with the patients have all been quarantined at home. — VNS
