The patient originally entered the nation on April 17 and was immediately brought to a concentrated quarantine facility at Canh Hung Hotel in Hong Bang district of the northern city of Hai Phong.
Once in quarantine, two COVID-19 tests were taken, with the results coming back negative twice on both April 19 and on April 30, respectively. Subsequently, he ended his quarantine period on May 1 and traveled to his apartment in Vinhomes Times City by taxi.
Following this, he went to Vinmec International Hospital on May 3 to undergo a further COVID-19 test, with the results being positive for the SARS-COV-2 virus on May 4. The patient was subsequently transferred to an isolation treatment at the National Hospital for Tropical Diseases.
At present, relevant units have been able to successfully trace six F1 cases who came into close contact with the patient, including his wife and children, in addition to three residents living in the same building.
Currently, his wife and children have been put into temporary isolation at their residence, while the three remaining individuals will be taken to a concentrated quarantine facility.
