One of the two cases, a 57-year-old man in Da Nang City, has five times tested positive for the SARS-CoV-2 virus. The infection marks the recurrence of the virus in the community 99 days after it was brought under the control.
Da Nang authorities moved to quarantine the place where he lives, lock down Hospital C where he visited for medical check-ups, track down those who had close and direct contact with the patient, and conduct extensive testing.
Local officials said a total of 103 people who had contact with the patient had tested negative for the virus.
The patient was transferred to Da Nang hospital for medical observation and treatment. He is on a ventilator due to respiratory failure.
Doctors are considering using the extracorporeal membrane oxygenation (ECMO), a life support machine, if the mechanical ventilation therapy does not help.
The other case is a five-year-old girl, living in Thai Binh province. She was among passengers boarding Vietnam Airlines’ VN5062 aircraft on a repatriation flight from Russia to Vietnam on July 9.
She twice tested negative for the virus but the third test came back positive on July 25.
The child is being treated at the Bac Lieu provincial General Hospital in the Mekong Delta.
With two more patients confirmed on July 25, Vietnam has so far recorded a total number of 417 COVID-19 cases. No deaths have been reported.
Except for 365 patients who have fully recovered, the remaining 52 cases are closely being monitored at health facilities across the country. Eight of them have tested negative at least once.
