The baby was diagnosed after arriving in Japan via Yanji. What is the real source of infection?

With the domestic epidemic under control, all walks of life began to resume work and production, and many people began to choose to travel. However, the epidemic situation abroad is still grim. In recent days, many places have reported cases of overseas COVID-19 people who have tested positive after leaving the country.

Bian Xiao thinks it may be an infection when leaving the country, and the specific source of infection needs to be investigated by relevant departments.

First, the specific process:

Three similar cases occurred within five days after a baby arrived in Japan via Yanji, and COVID-19 was positive.

At present, I am under isolation observation in Japan and have no symptoms such as fever.

The baby (and his mother) returned to Yanji from Japan on February 20 19, and had no travel history or contact history with COVID-19 cases.

In August 14, I went back to Japan for nucleic acid testing in Yanji, and the results of maternal and child nucleic acid testing were negative.

On August 15, I took the high-speed train from Yanji to Harbin, and on August 16, I flew from Harbin to Tokyo, Japan, where I tested positive for COVID-19 antigen.

After receiving the report, the health departments at the state and city levels quickly launched emergency plans and carried out comprehensive prevention and control measures such as epidemiological investigation, nucleic acid detection and isolation control.

At present, 66 close contacts and sub-close contacts have been isolated and controlled, and the nucleic acid test results are all negative.

Secondly, Bian Xiao called on everyone to take preventive measures.

At the same time, the relevant places will be disinfected, and the contact personnel who have been in the field will be sent an investigation letter to the relevant units.

Under the situation of normalization of epidemic prevention and control, the broad masses of people are requested to maintain good hygiene habits, strengthen the protection of individuals and their families, wear masks scientifically, wash their hands frequently and ventilate frequently, and keep a social distance of more than one meter to avoid gathering less and leaving more.

If you have symptoms such as fever and cough, you should wear a disposable medical mask or above, go to the nearest fever clinic for investigation and diagnosis in time, try to avoid taking public transport during the medical treatment, and actively inform the doctor of your travel history and contact history in the past 14 days.

May the epidemic end at an early date.
