COVID-19 is group B, the average incubation period is 4 days

Accordingly, Deputy Prime Minister Tran Hong Ha has just signed Decision 26/2023/QD-TTg amending the Appendix regulating the average incubation period and the period of time when no new cases of infectious diseases are detected as a basis for declaring the end of an infectious disease epidemic, issued together with Decision No. 02/2016/QD-TTg dated January 28, 2016, regulating the conditions for declaring an epidemic and declaring the end of an infectious disease epidemic.

Specifically, the group, average incubation period and time without detecting new cases of COVID-19 (formerly known as acute respiratory infection caused by a new strain of Corona virus) are added. Accordingly, COVID-19 belongs to group B, the average incubation period is 4 days, the time without detecting new cases is 8 days.

Previously, according to the provisions of Decision No. 07/2020/QD-TTg amending and supplementing a number of Articles of Decision No. 02/2016/QD-TTg dated January 28, 2016 of the Prime Minister on the conditions for declaring an epidemic and declaring the end of an infectious disease epidemic, the average incubation period of COVID-19 is 14 days and the time without detecting any new cases of COVID-19 is 28 days.

The Ministry of Health said that the revision of the average incubation period to reduce from 14 days to 4 days and the time without detecting new COVID-19 cases to reduce from 28 days to 8 days is based on scientific grounds; the current developments of the COVID-19 epidemic; and according to the recommendations of the World Health Organization and the US Centers for Disease Control and Prevention.

According to the Ministry of Health , the transfer of COVID-19 from group A to group B is due to information comparing the provisions of the Law on Prevention and Control of Infectious Diseases and the actual developments of the epidemic in Vietnam, showing that COVID-19 no longer meets the criteria for group A infectious disease, specifically as follows:

1. From the beginning of the year to August 31, 2023, 97,628 cases were recorded, with an average of about 12,000 cases recorded per month; the average number of cases per month decreased 12 times compared to 2021 (about 144,000 cases/month) and decreased 68 times compared to 2022 (about 816,000 cases/month). The mortality rate due to COVID-19 decreased from 1.86% in 2021 to 0.1% in 2022 and is currently 0.02% in 2023 (as of the end of August 2023), equivalent to or lower than the mortality rate of some common group B infectious diseases recorded in Vietnam in the past 5 years such as: dengue fever (0.022%), malaria (0.017%), diphtheria (0.102%), whooping cough (0.417%);

2. The causative agent of COVID-19 has been clearly identified as the SARS-CoV-2 virus;

3. COVID-19 currently meets the criteria of Group B infectious diseases as prescribed in Point b, Clause 1, Article 3 of the Law on Prevention and Control of Infectious Diseases: dangerous infectious diseases that can spread rapidly and can cause death.
