Anti-epidemic SMS prompts who may be exposed and who is seriously exposed.

Among the "possible exposure" and "contact" prompted by epidemic prevention SMS, the contact is more serious.

Interpretation and analysis: when asked which is more serious, it can only be compared. The correct official statement of "possible exposure" is "suspected exposure", that is, people who have contacted infected patients, wild animals, or articles or environment contaminated by viruses in novel coronavirus, but at the same time have not taken appropriate protective measures. This may be a person or an animal.

And "contacts" usually refer to "close contacts", that is, people who have had contact with confirmed cases (including suspected, confirmed and asymptomatic infection cases) but have not taken effective protective measures, so the two should not be underestimated, but compared with each other, they belong to "close contacts" seriously.

Dense connection judgment:

If you have had close contact with suspected cases and confirmed cases five days before symptoms appear, or have had close contact with asymptomatic infected samples five days before sampling without effective protective measures, such as living together, taking cars, planes, high-speed trains, ships and other means of transportation, or having close contact with offices, workshops, classrooms, canteens, elevators and other places, or having eaten and entertained in a closed environment, it may be possible.
