A woman has tested positive for COVID-19 after completing her 21-day quarantine period at a centralized facility in the Mekong Delta province of An Giang.

The 57-year-old woman, who hails from An Phu District, An Giang Province, returned to Vietnam from Cambodia on May 30, the provincial Steering Committee for COVID-19 Prevention and Control confirmed on Monday.

She was brought to a centralized quarantine center in Tri Ton District following her arrival.

After completing the 21-day quarantine period, during which she tested negative for the novel coronavirus three times, she was required to undergo home quarantine for another 14 days.

On Monday, her fourth test returned positive, and she was confirmed as COVID-19 patient No. 15,950 by the Ministry of Health later the same day.

The woman has been admitted to the medical center in An Phu District for quarantine and treatment.

She is currently in stable health and does not have such symptoms as a fever, coughing, or difficulty breathing.

Her 12 direct contacts have been identified and quarantined in accordance with regulations.

Vietnam previously required international arrivals and direct contacts of COVID-19 patients to undergo a 14-day quarantine period at centralized facilities.

The period was extended to 21 days on May 5 following several cases of people testing positive for the virus after completing their 14-day quarantine.

As of Tuesday morning, Vietnam has recorded 16,136 coronavirus cases, with 6,519 recoveries and 76 deaths, according to the Ministry of Health statistics.

The country has recorded 12,788 local infections in 48 provinces and cities since a new outbreak began on April 27.

An Giang has detected only one case in this bout and has gone nine days without reporting a community-based infection.
