Under the plan, the test subjects will be divided into three groups based on risk levels, with red representing those with the highest risk of infection, followed by orange denoting those at-risk, and green meaning low-risk people.
Falling in the “red group” category are areas in very high-risk and high-risk communes and wards in accordance to Decision No. 2686/QD-BCĐQG dated May 31, 2021 of the National Steering Committee for COVID-19 Prevention and Control. The high-risk subjects, based on epidemiological factors, are those who travel a lot, who are highly exposed, such as people involved in supply chains, markets, frontline forces, workers, security guards at buildings, and other high-risk areas, and other high-risk subjects according to experts' epidemiological indications.
The “orange group” comprises factories, enterprises, production facilities, agencies, units, markets, supermarkets, hospitals, medical examination and treatment establishments... and areas located in risk zones in line with the Decision No. 2686. Other subjects and other at-risk areas as designated by epidemiological expertise.
The “green group” includes people in the epidemic free area.
In inner-city districts and high-risk localities, one sample will be collected from each household, from one family member at the highest risk.
Tests for F0 and F1 cases and those entering Vietnam from abroad, or returning from epidemic-hit areas, and other subjects will be performed in line with the law.
The city will use two testing methods: Realtime RT-PCR technique and quick test. The RT-PCR method will be given priority to avoid missing any infection cases.
From August 9 to 17, around 1.3 million tests using RT-PCR technique will be conducted for all people in the "red group"; those showing symptoms of cough, fever, difficulty in breathing; and some subjects in the "orange group," including medical staff, patients, frontline forces, those involved in food supply chains, markets, supermarkets, drivers, shippers, guards at buildings; and households in the “green group”, with one sample from each household.
Along with RT-PCR testing for people in the "red group" and "green group" in high-risk districts, the remaining districts will actively perform rapid tests as guided by the Hanoi Center for Disease Control (CDC), with the total of 2 million rapid tests.
The capital city has so far reported a total of 1,943 COVID-19 infection cases since the fourth COVID-19 wave started on April 27.
