The assumption made by many experts is that the patient can have an incubation period of more than 14 days;
Doctor Nguyen Hong Ha, Vice President of the Vietnam Association of Infectious Diseases, leans towards the hypothesis that quarantined people’s incubation period lasts more than 14 days.
The comment made by Dr. Ha when analyzing the context of 3 people testing positive after completing 14 days of centralized quarantine and having at least 2 negative nCoV tests.
Doctor Truong Huu Khanh, Children’s Hospital 1, Ho Chi Minh City, on May 4, leaned towards the hypothesis of cross-infection in the quarantine area, maintaining the opinion he shared with VnExpress on April 30.
Associate Professor, Dr. Nguyen Huy Nga, former Director of the Department of Preventive Medicine, and Mr. Tran Dac Phu, Senior Advisor of the Vietnam Public Health Event Emergency Response Center, both noted the above two hypotheses.
However, Mr. Phu commented that there is a high possibility of infection in the quarantine area, based on epidemiological investigation and gene sequencing results.
Nhu Nguyet 2 Hotel is the place where two delegations of Indian experts and Chinese experts are quarantined.
The Ministry of Health suspects that 5 Chinese experts were cross-infected with the Indian expert group at the quarantine hotel.
According to Mr. Phu, the risk of infection after the quarantine period still exists even though the rate is low, with cases incubation after 14 days or tests giving false negative results…
`The issue of identifying the source of infection is also very important to guide tracing and assessing the scale of the epidemic. However, the important thing now is to prioritize tracing all F0, F1, F2… in the community to avoid infection.

Should the centralized quarantine period be extended?
On May 4, the Department of Preventive Medicine, Ministry of Health requested centralized quarantine areas to temporarily extend the time and not yet resolve all subjects who have met the conditions to be released from quarantine.
Experts recommend that authorities need to strictly manage people in centralized quarantine areas.
According to Mr. Tran Dac Phu, the 14-day quarantine period is basically safe and does not need to be increased.
What needs to be done now is to review the process, tighten actual centralized quarantine management and monitor patients after returning to the community according to regulations of the Ministry of Health, according to Dr. Khanh. If done correctly,
However, there is also the opposite view.
To respond to cases where quarantined people have an incubation period of more than 14 days, Dr. Hong Ha believes that local authorities need to increase supervision for about a week with the group of people who have finished quarantined.
Localities also need to comply with the 5K measure.
The number of community infections in the country from April 27 to present is 38, including the case of Nhu Nguyet 2 hotel staff infected in the quarantine area of the Indian delegation.
