`Patient 2899` was recorded by the Ministry of Health on the afternoon of April 29, as a 28-year-old man, from Dao Ly commune, Ly Nhan district, Ha Nam province.

On the afternoon of April 29, this person’s father, mother, wife and daughter tested positive for nCoV.

Mr. Tran Dac Phu, Senior Advisor to the Vietnam Public Health Event Emergency Response Center, said that `patient 2899` tested positive after returning from the quarantine area, many factors must be considered,

Mr. Phu pointed out 3 possibilities of infection.

In addition, after completing the centralized quarantine period, the patient moves home and comes into contact with many people.

Experts believe that specific epidemiological investigations are needed to be able to draw accurate conclusions, but cannot conclude that `the patient has an incubation period of over 14 days`.

`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

Mr. Tran Dac Phu.

An anonymous epidemiologist said there are many possibilities about the source of infection of `patient 2899`.

Currently, experts have not ruled out any possibilities and need more evidence, such as virus gene sequencing results, investigation of the testing process, and epidemiological history, to clearly determine the patient’s source of infection.

Doctor Truong Huu Khanh, Children’s Hospital 1, Ho Chi Minh City, said that Mr. 2899 could have been infected in the quarantine area because this location had recorded people infected with nCoV during his quarantine period, or infected from Japan but when

`It is necessary to clarify the time of the last test of `patient 2899` at the Da Nang quarantine area to clarify these two possibilities,` Mr. Khanh said and agreed with Mr. Phu’s third hypothesis.

After the centralized quarantine period, people returning to the locality are required to quarantine at home for another 14 days and closely monitor their health.
