What do you mean by popular countries?

Epidemic countries are countries or regions where animal diseases are prevalent, and refer to countries or regions where viruses or germs can spread. The epidemic area is limited by the mode of transmission and environmental conditions.

The epidemic area refers to the range where the carrier's droplets can spread, and the spread range of animals is determined according to their range of activities. When the number of infectious diseases gradually expands and reaches a certain number, they cross, expand and overlap with each other, forming an epidemic area.

Because the spread range of animals is determined according to the range of animal activities and the control is strict, the goods exported from epidemic areas will also face strict inspection and quarantine.

/kloc-If there is a life history of an epidemic area within 0/4 days (prefecture-level cities and districts with medium and high risks in China, the same below), it will pass the nucleic acid test twice within 48 hours (24 hours apart).

Each port can take centralized or home waiting for the results according to the specific situation, and individuals should do a good job in health monitoring.
