A COVID-19 patient in the northern Vietnamese province of Hai Duong who was given the all-clear on September 1 has retested positive for the coronarvirus, the provincial Center for Disease Control said on Monday.

The 34-year-old man was placed in quarantine at the dormitory of Hai Duong University on August 14 for having links to a local outbreak.

He tested positive for the coronavirus on August 17 and was identified as Vietnam's COVID-19 patient No. 972.

He received treatment at the Hai Duong Hospital for Tropical Diseases until September 1, when he was declared free of the virus and discharged from the infirmary.

He practiced home quarantine for 14 days following the hospital discharge, during which he tested negative for the virus four times.

On Saturday last week, the patient was sampled for a fifth test, which returned positive.

Another test conducted by the National Institute of Hygiene and Epidemiology on the following day confirmed the positive result.

He is now quarantined and treated at the Hai Duong Hospital for Tropical Diseases.

The man is reported to be feeling well without exhibiting any symptoms related to the pathogen.

The local administration also sampled all of his family members including his wife, two children, and a helper for COVID-19 testing.

All of their test results have returned negative.

The patient’s family members are required to self-quarantine at home, monitor their health, and frequently disinfect household appliances with antiseptic.

One-hundred and 77 people remain under quarantine in Hai Duong Province.

Vietnam has gone 20 days without registering a locally-transmitted COVID-19 case. 

The national tally stands at 1,068 cases, including 947 recoveries and 35 virus-related deaths.
