GUIDELINES
COVID-19 MONITORING AND PREVENTION
(Issued together with Decision No. 3985/QD-BYT dated October 29, 2023 of the Ministry of Health)
I. GENERAL CHARACTERISTICS
COVID-19 is an acute infectious disease caused by the SARS-CoV-2 virus. This virus mutates regularly, resulting in more infectious variants. According to monitoring results, Vietnam has recorded the majority of variants common in the world. The Omicron variant of SARS-Cov-2 is the most common variant in Vietnam and in the world at present.
...
...
...
Clinical manifestations of SARS-CoV-2 patients vary, ranging from no symptoms, mild symptoms to severe pneumonia, acute respiratory distress syndrome, sepsis and multiple organ dysfunction syndromes and death. People who are at higher risk of severity include the elderly, those with underlying conditions, including diabetes mellitus/cardiovascular disease, those with immunodeficiency diseases and pregnant women. Now, preventive vaccines and antiviral drugs for treatment are available.
On May 5, 2023, the World Health Organization (WHO) announced that COVID-19 no longer constitutes a public health emergency of international concern, but advised that countries still implement monitoring and prevention measures and make the transition from pandemic prevention to sustainable management.
These guidelines are formulated, updated and adjusted on the basis of actual COVID-19 containment and COVID-19 monitoring, prevention and control as appropriate to current situation and they shall be implemented by provincial governments, health units and relevant units according to actual local situation.
II. MONITORING GUIDELINES
1. Definition of cases
Suspected cases (monitored cases):
a) Suspected cases are those with:
- Symptoms: fever and cough; or
- At least three of the following symptoms: fever, cough, headache, body ache - fatigue - chill; throat pain, runny or stuffy nose; reduction or loss of taste or smell; nausea, vomiting, diarrhea or difficulty breathing.
...
...
...
1.2. Confirmed cases (F0 cases):
a) Confirmed cases are persons getting SARS-CoV-2 positive test results via genetic material detection testing (Realtime RT-PCR).
b) Confirmed cases are persons mentioned in Section 1.1. and getting positive rapid antigen test results for SARS-CoV-2.
2. Definition of epidemic hotspots
2.1. Epidemic hotspot is an area where there are at least 02 cases with epidemiological connection*, at least one of which is the confirmed cases, Depending on the level of epidemiological connection, the scope of epidemic hotspots shall be determined as appropriate to reality (household/accommodation, household clusters, offices, classrooms or equivalent areas).
* Person meeting epidemiological criteria is a person who closely contacts with confirmed cases or is involved in cluster of confirmed cases
2.2. Inactive epidemic hotspot: An epidemic hotspot is considered inactive if no new cases are recorded after 8 days from the date on which the last confirmed case was detected and managed.
3. Monitoring contents
...
...
...
- Collecting samples of the first 5-10 cases from places where there are many suspected cases to determine epidemic hotspots.
- Quickly collecting samples from people suffering from severe respiratory tract infection or people who are at higher risk of severity (the elderly, those with underlying conditions, including diabetes mellitus/ cardiovascular disease, those with immunodeficiency diseases and pregnant women).
- Integrating COVID-19 monitoring into the system for monitoring respiratory pathogen, including monitoring of influenza-like illness (ILI), monitoring of severe viral pneumonia (SVP) and monitoring of genetic characteristics of SARS-CoV-2 to monitor its variants.
4. Sample collection, preservation and transport
- Sample collection, preservation and transport are specified in Appendix 1.
- Test request forms and reports on test results are provided in Appendix 3.
5. Reporting

a) Method for nasopharyngeal swab collection
- Ask the patient to sit still, sneeze nasal discharge into tissue paper, and tilt their head slightly backwards. Children shall be held by adults.
- Tilt the patient’s head back 70° and support the back of the patient’s neck with one hand.
...
...
...
Note: if resistance is met before reaching such depth, remove the swab and try the other nostril. When reaching the posterior nasopharynx, stop, rotate the swab and slowly remove it.
- Keep the swab in place for 5 seconds to ensure maximum absorbency.
- Slowly rotate and remove the swab.
- Put the tip of the swab in a vial containing transport medium and break the shaft of the swab at the score mark to fit it in the vial. Note: the nasopharyngeal swab and the throat swab shall be put together in one vial.
- Recap the vial tightly and wrap it in paraffin paper (if any).
Note: Children shall sit in their parents’ laps with their backs to their parents' chests. The parent shall hold the child’s body and hands tightly and tilt the child’s head back.
Insert the sterile swab in a straight line into one nostril (do not tilt upwards) along the nasal floor until reaching the pharynx.

...
...
...
- Ask the patient to open their mouth wide.
- Use a tongue depressor to hold the patient’s tongue down.
- Insert the swab into the throat, rub and rotate the swab 3-4 times against both tonsils and the posterior pharyngeal wall to obtain secretion and cells from the throat.
- Place the swab in a vial containing 3ml of transport medium (VTM or UTM) for preservation. Note that the tip of the swab shall be completely submerged in the transport medium. If the swab is longer than the vial, cut or break its handle to fit it inside the vial.

Integration of COVID-19 vaccination into regular immunization:
1. Integration principles
- According to the number of recipients, the quantity of vaccines provided, expiry date, vaccine storage conditions and immunization practices, provincial governments shall consider deciding COVID-19 vaccination on a regular/monthly/periodic basis.
- Organizing widespread communication about COVID-19 vaccination and notifying people of vaccination time and location.
- Organizing a COVID-19 vaccination session which is separated from other regular immunization sessions in order to ensure safety and avoid confusion because COVID-19 vaccine recipients are different from vaccine recipients of regular immunization:
- Vaccine plan formulation, allocation and distribution, arrangement of locations, resources, vaccination devices, organization of vaccination sessions, statistics, report on vaccination results and monitoring, supervision, and report on post-vaccination reactions shall comply with regulations of Government's Decree No. 104/2016/ND-CP dated July 01, 2016 and relevant Circulars and instructions of the Ministry of Health.
- Vaccine demands shall be identified according to people's vaccination needs for recipients under the guidance of the Ministry of Health and recommendations of WHO.
2. Vaccine recipients
- High priority group: the elderly, adults with underlying conditions, including diabetes mellitus/cardiovascular disease, people with immunodeficiency diseases and pregnant women and frontline medical staff.
...
...
...
- Low priority group: Healthy children and adolescents (5-18 years of age).
